If you compare an optical lens to a human eye, [optical lens] is like an eyeball. It is directly related to the distance, range, and effect of the object. There are many kinds of optical lenses, which can be divided into short focal length, medium focal length, long focal length and zoom lens. They can be divided into wide-angle, standard and low price YLF laser crystal according to the size of the field of view. Can also be divided into fixed aperture fixed focus lens, manual aperture fixed focus lens, automatic aperture fixed focus lens, manual zoom lens, auto iris power zoom lens, electric three variable lens (aperture, focal length, focus can be all three) Types of. Lens imaging is more or less distorted. Larger distortions can cause significant problems for the vision system. In imaging design, detailed consideration should be given to this, including the use of a lens with a small distortion, and an effective field of view with only a small field of view. Another characteristic of an optical lens is its spectral characteristics, which are mainly affected by the interference characteristics of the lens coating and the absorption characteristics of the material. It is required that the light of the ideal high resolution of the optical lens should be matched with the illumination wavelength, the wavelength accepted by the custom high purity KTP nonlinear crystal, and the light transmittance of the optical lens to the wavelength should be as high as possible. Some special effects can be achieved by selecting appropriate filters in the imaging system. In addition, the design of the imaging optical path also needs to pay attention to the influence of various stray light. In recent years, the use of image measurement of item size has become a trend in the industry. Advances in equipment such as cameras, imaging software, and lighting components have made the accuracy of image-measuring items comparable or better than manual or laser measurements. Integrating the application of optical system engineering, we can find out the quality of the optical product determines the quality of the system, and the telecentric lens can perform various forms of optical measurement. Software engineering requires images with high resolution, high contrast and low geometric distortion to determine accurate measurement data. In addition to the requirements of the optical device itself, the choice of viewing angle is also of considerable importance. Measuring objects under inappropriate observation points can cause distortion of the image captured by the object. In addition to the interference that can occur during image processing, system designers also consider several limitations of optical equipment that can affect the accuracy of optical measurements: 1. Abnormal enlargement due to the placement of objects 2. Image deformation 3. Error caused by angle of view selection 4. Low image resolution 5. Uncertainty of boundary caused by inappropriate light source interference Telecentric lenses can effectively reduce or even eliminate the above problems, so telecentric custom BBO nonlinear crystal have become a decisive factor in precision optical measurement systems.

With the advent of the Industry 4.0 era, the role of machine vision in the field of intelligent manufacturing is becoming more and more important. Next, Conrad Smart will take you to understand how machine vision technology works, why it is process automation and quality improvement. The right choice. A wholesale infrared Germanium lenses is an optical contactless sensing device that automatically receives and interprets images of real scenes to obtain information to control the machine or process. Machine vision is the automatic extraction of information from digital images for process control or inspection of manufactured products. The information on the computer display is used to obtain the production inspection status of the product at a glance, achieving easy and efficient intelligent effects. As each bottle moves past the detection sensor, the detection sensor will trigger the vision system to emit a stroboscopic light and take a picture of the bottle. Once the image of the bottle is captured and saved to memory, the vision software will process or analyze the image and send a pass-fail response based on the actual fill level of the bottle. If the vision system detects that a bottle is not filled in place, ie fails the test, the vision system will signal the diverter to remove the bottle from the production line. The operator can view the rejected bottles and ongoing process statistics on the display. Guide the robot to align the components during the manufacturing assembly process, determine the spark plug gap or provide position information. The example shown in Figure 2 mainly shows how the smart wholesale large size infrared Silicon optics can be used for the oil filter (right) pass or fail detection, and measurement The width of the central shaft head on the bracket (left). The composition of the optical lens: 1. Image acquisition: light source, lens, camera, capture card, mechanical platform; 2. Image processing and analysis: industrial control host, image processing analysis software, graphical interactive interface; 3. Judgment execution: telex unit, mechanical unit. Although human vision is good at qualitative interpretation of complex and unstructured scenes, machine vision is good at quantitative measurement of structured scenes by virtue of speed, precision and repeatability, which can effectively avoid fatigue due to long hours of work. And the problems caused by work omissions, etc., to maintain a long working condition. By eliminating direct contact between the inspection system and the component being inspected, the multispectral/cleartran and standard CVD ZnS optics also prevents component damage and also avoids maintenance time and cost of mechanical component wear. Machine vision also brings additional security and operational advantages by reducing manual involvement in the manufacturing process. In addition, machine vision also protects the clean room from human contamination and protects workers from the dangers of a hazardous environment.

An optical lens is a key component in an optical lens. Its basic function is to transform an optical signal into an ordered electrical signal. Choosing the right large size YVO4 laser crystal is also an important part of the design of intelligent optical lens. The optical lens not only directly determines the image resolution and image quality, but also directly relates to the operating mode of the whole system. Optical lens performance advantages A good optical lens should have high precision, high definition, good color reproduction, low noise, etc., and can be programmed to control the exposure time, brightness, gain and other parameters through the computer, and the image window is steplessly scaled with an external trigger input. Features such as flash control output. Microvision, a well-known optical lens manufacturer and seller in China, combines years of R&D and production experience with customer needs, and carefully selects the precautions and necessary parameters when selecting wholesale YLF laser crystal, so that general customers can make reasonable choices. Basic parameters of [optical lens] Resolution The number of pixels of the image captured by the camera each time generally corresponds to the number of pixels arranged on the surface of the photosensor, such as 1920*1080. Pixel depth The number of bits per pixel data is usually 8bit, 10bit, 12bit. The resolution and pixel depth together determine the small size of the image. For example, for a 5 megapixel pixel with a pixel depth of 8 bits, the entire image should have 5 million*8/1024/1024=37M (1024bit=1KB, 1024KB=1M). Increasing the pixel depth enhances the accuracy of the measurement, but it also reduces the speed of the system and increases the difficulty of system integration (increased cable, larger size, etc.). Large frame rate/line frequency The speed at which the camera captures and transmits images is typically the number of frames captured per second (Frames/Sec) for area array cameras and the number of lines (HZ) collected per second for line array cameras. Exposure method and shutter speed The high precision YVO4 laser crystal is a progressive exposure method. You can select the fixed horizontal frequency and external trigger synchronization. The exposure time can be consistent with the line period, or you can set a fixed time. The area array camera has frame exposure, field exposure and scrolling. There are several common ways of exposure. Industrial digital cameras generally provide external triggering. The shutter speed is generally 10ms, and the high-speed camera is faster. Cell size The cell size and the number of pixels (resolution) together determine the size of the camera's target surface. At present, the industrial digital camera pixel size is generally 3μm~10μm. Generally, the smaller the pixel size is, the more difficult it is to manufacture, and the less the image quality is improved. Spectral response characteristics It refers to the sensitivity of the pixel sensor to different light waves. The general response range is 350nm~1000nm. Some cameras add a filter in front of the target to filter out the infrared. If the system needs to be sensitive to infrared, the filter can be removed. Optical lens] noise Noise refers to signals outside the actual imaging target that are not desired to be acquired during imaging. Generally divided into two categories, one is the shot noise caused by the effective signal, this kind of noise exists for any camera; the other is the inherent noise of the camera itself and the signal without light. It is due to the inherent noise caused by the image sensor readout circuit, camera signal processing and amplification circuit, and the inherent noise of each camera is different. Signal to noise ratio The signal-to-noise ratio of the camera is defined as the ratio of signal to noise in the image (the ratio of the average gray value of the effective signal to the root mean square of the noise), which represents the quality of the image. The higher the image signal-to-noise ratio, the better the camera performance and image quality. .

According to a survey of optical lenses, 52 users and 8 manufacturers were surveyed, 55% of which were from Europe, 23% from North and South America, 22% from Asia/Middle East, and held in Stuttgart. The results of the survey were announced at the VISION2016 conference. Europe ranks among the best in terms of procurement and production, with a market share of 62% and 43% respectively. Manufacturers are also producing in Asia (13%) and the US (6%). After Europe, Asia and the United States have the same strong purchasing market, each occupying 28% of the market. Compared with 2015, the US market share in production fell to 28%, which may also be affected by the small number of vendors participating in the survey in North and South America. Optical lens manufacturers say that from a sales point of view, measurement and logistics account for 50% and 13% respectively; production automation and quality assurance applications each occupy 63% of the market; medical diagnostics and scientific applications also occupy A 38% market share. Survey data from large size YVO4 laser crystal users also showed similar results: 48% of cameras were used in the automation field, 46% for quality assurance applications, 40% for measurement and 29% for scientific applications. Medical diagnostic applications account for 10% of user camera deployments. Transportation applications (including vehicle assistance systems) are also an important market for manufacturers, but for users, this market is not as important. As in previous years, camera manufacturers and system developers have seen continued growth in the image processing and machine vision industries, with 90% of users planning to roll out or replace existing equipment in the next two years. Camera pricing For the medium-priced high precision YVO4 laser crystal production ratio between 150-650 US dollars, in the manufacturer's production roadmap, it has steadily dropped from as high as 70% in 2014 to 44%, indicating that the price has passed the previous years. After a continuous decline, it has been relatively stable. For low-cost cameras below $150, the manufacturer's production ratio and user purchase ratio are 26% and 11%, respectively, and the importance is relatively low. Compared with 2015, high-priced cameras have dropped by 12 percentage points from $650/$1,000/$3,000 (see Figure 1). Therefore, for small camera manufacturers, producing customized cameras for specific applications seems to be a strong selling point and market advantage. CMOS compared with CCD As Sony stopped producing CCD image sensors, users have witnessed tremendous growth in the performance of companies such as ON Semiconductor, which currently accounts for 29% of the market. In last year's study, the decline in Sony users and manufacturers' expectations was not realized, and 32% of camera manufacturers still rely on Sony. In the next two years, Sony is expected to return to its market share before the announcement of the CCD shutdown: 37%. Compared with 2015, more users chose Sony in 2016, and the proportion of users increased from 35% in 2015 to 53% in 2016. Camera manufacturers point out that CMOS technology accounts for 85% of camera sales. Camera users are expected to reach this level of purchase in the next two years. Today, 51% of users use CMOS, but this percentage is expected to grow to 83% soon. With the gradual replacement of CCD technology, e2v will benefit from camera manufacturers (from 3% to 12%) and custom sensors (from 4% to 19%), both of which have shown the same positive prediction. In 2015, about 30% of users used sensors below 1 million pixels, but in 2016 this percentage dropped to only 10%. The use of 1 million pixel sensors has dropped significantly, resulting in an increase in usage of 1 to 3 million pixel products (up 10%), 3 to 5 million pixel products (up 2%), and 500 to 10 million pixel products (up 3%). In the next two years, manufacturers and users are expected to focus their applications on applications with frame rates between 25 and 60 fps. At the same time, applications with frame rates in excess of 100fps (user-oriented: 13% growth) and 200fps (for manufacturers: growth of 14%) began to increase significantly compared to 2015. According to survey data from wholesale YLF laser crystal manufacturers, GigE Vision is currently the most popular interface standard (33%), followed by Ethernet (15%). Compared with 2015, the proportion of the high proportion of Ethernet interface standards has declined in the past due to the low participation rate in the United States. Both camera manufacturers and users expect USB 3.0 and GigEVision to experience rapid growth with market growth rates of 8% and 10% respectively. Today, more than 75% of manufacturers and 60% of users believe that 5GB or more of bandwidth becomes critical. For interface selection for high-speed applications, feedback from camera manufacturers: 50% of manufacturers believe that USB 3.1 is an important interface for high-speed applications; 38% of manufacturers believe that 10GigE is ideal for high-speed applications. Let's take a look at feedback from users: 44% of users support high-speed transmission through 10GigE; and the proportion of users who support high-speed transmission via USB3.1 is 37%.

The robot vision inspection system is characterized by increased flexibility and automation. In some dangerous working environments that are not suitable for manual work or where artificial vision is difficult to meet the requirements, machine vision is often used instead of manual detection. At the same time, in large-scale industrial production process, manual visual inspection is used to check product quality with low efficiency and low precision. Machine vision inspection methods can greatly improve production efficiency and automation of production. Moreover, machine vision is easy to implement information integration, and is the basic technology to realize computer integrated manufacturing. The product can be measured, guided, detected, and identified on a fast-producing production line, and the production task can be completed with quality and quantity. In a robotic vision system, it is important to get a high quality, manageable image. The success of the system must first ensure that the image quality is good and the features are obvious. The failure of a machine vision inspection project was mostly due to poor image quality and inconspicuous features. To ensure a good image, you must choose a suitable zero order/multiple order/achromatic optical waveplate. Basic elements of optical lens selection Contrast: Contrast is very important in smart high precision optical waveplate. The illumination task of machine vision applications is to create a large contrast between the features that need to be observed and the image features that need to be ignored, thus facilitating the differentiation of features. Contrast is defined as having a sufficient amount of grayscale difference between the feature and the area around it. Good lighting should be able to ensure that features that need to be detected stand out from other backgrounds. stability: Another way to test a good light source is to see if the light source is sensitive enough to the position of the part. When the light source is placed in a different area of ​​the camera's field of view, the resulting image should not change. A highly directional light source increases the likelihood of specular reflections in the highlighted area, which is detrimental to subsequent feature extraction. brightness: When choosing two high-quality laser grade optical waveplate, the better choice is the brighter one. When the light source is not bright enough, there may be three bad conditions. 1. The signal to noise ratio of the camera is not enough; 2, because the brightness of the light source is not enough; 3. The contrast of the image is not enough, and the possibility of noise appearing on the image also increases.

Optical lenses have a higher advantage in image stability, anti-interference ability and data transmission. They are a key part of the machine vision system. The performance of the purchasing BIBO nonlinear crystal determines the stability of the machine vision system. First determine the project requirements, determine the resolution of the camera according to the field of view and detection accuracy, determine whether to use the CCD or COMS according to the speed of the object being photographed, or determine the camera frame rate according to the unit time requirement of the captured image. Determine what connection method to use (USB or Gigabit, etc.) based on the project site environment. Therefore, choosing customized large size and special shape CaF2 optics suitable for an automated vision project is critical to the success of the entire project. Summarize the following points: 1. Items that require testing, such as size, or yo! 2, the state of the workpiece, the movement is still still! 3. Product size and detection speed. 5. What is the background color of the workpiece! 6, product reflective is good, product batch consistency is the same! The parameters to be noted when selecting the camera: 1, camera type For still detection or general low speed detection, the area array camera is preferred, and linear array cameras are considered for special applications such as large-format high-speed motion or roller motion. Depending on the speed of detection, the frame rate of the selected camera must be greater than the speed of the object's motion, and must be completed within the exposure and transmission time of the camera. 2, camera resolution If the measurement accuracy of the project and the field of view size, then the selected camera pixel calculation relationship is as follows: Camera resolution (L/W) ≥ field of view (L/W) / accuracy. If the project requires a field of view of 100mm*75mm and an accuracy requirement of 0.05mm, the camera's pixel length is 100/0.05=2000PIX, which is a camera that requires 2000*1500=3000000=3 million pixels. This is just the pixel accuracy of the camera, it does not mean that the accuracy of the entire system is so high, there are other precisions to consider, such as the resolution of the lens, the jitter of the system, the wavelength of the light source, and so on. The pixel precision of the purchase plano/spherical/aspherical/cylindrical CaF2 optics must be higher than the precision required by the system, so that the actual measurement significance can be realized. The accuracy improvement of the sub-pixel does not have much influence in the actual measurement, and the problem of insufficient precision cannot be fundamentally solved. In general, if conditions permit, we will require an increase in the resolution of the camera by an order of magnitude or an increase in the pixel accuracy of the camera by an order of magnitude. 3, camera frame rate The camera's frame rate determines the measurement efficiency of the device. If the camera's frame rate is 30FPS, it will take 30 shots per second. And if the speed of the camera is 120FPS, if the algorithm is fast enough, then 120 products can be detected every second. In general, the lower the resolution of the camera, the higher the frame rate of the same interface, and the higher the resolution, the lower the frame rate. Frame rate * resolution ≤ bus bandwidth, that is, when the interface is certain (bus bandwidth has been determined), the frame rate also has a large value when the resolution is constant. That is, if the resolution of the camera is fast and the frame rate of the camera is high, then it is necessary to find a bus with a larger bandwidth, that is, an output interface of the camera. 4, camera output interface Under the same pixel condition, the camera frame rate of the bus of various interfaces is different. Generally, Camera Link>USB3>GIGE>1394B>USB2, 1394A. Now the Camera Link bus is fast. The theoretical speed of USB3 is 5Gbps or 640MB. In actual performance, there should be 80% effective bandwidth, that is, the total bandwidth of 512M is available for actual transmission, so if a 5 megapixel The camera, 5M per image, can reach 100 frames per second, and the speed is not fast. For the GIGE Gigabit network camera, the 5 megapixel camera can achieve 23FPS faster. 1394B's 5 megapixel camera can do 13FPS, USB2, 1394A is generally 5 to 6 frames.

Analog controller The analog brightening integrated module combines the functions of both the analog controller and the brightening module. A separate brightening module requires an external input of 24v, while the analog brightening integrated module has a 24v voltage output inside, which does not require external power. It has an infinitely adjustable function, and the customer can adjust the input voltage by simulating the knob outside the integrated module to control the brightness of the light source. The analog brightening integrated module has the following features: 28v output, short rising edge time (2us), 3 standard channels, each controllable and trigger function. Digital controller The digital brightening integrated module integrates the digital controller and the controller of the brightening module function. It has the following functions: 256-level brightness adjustment function (4 channels for standard channels, individually controllable brightness for each channel), computer communication function (RS232 interface), and brightness enhancement. The light source will not light when the product is not triggered, and the light source will only be on and off when triggered. The key part of the low price YLF laser crystal designed for machine vision applications is the reflected light on the surface of the object. The geometry, gloss and color of the surface of the object determine how the light reflects on the surface of the object. The choice of machine vision application light source comes down to how to control the light reflection of an object. If the reflected light is well controlled, the acquired image can be controlled. The optical controller is the main purpose of the machine custom BBO nonlinear crystal controller to supply power to the light source, control the brightness of the light source and control the illumination state of the light source (bright\off), and also realize the strobe of the light source by triggering the signal to the controller, thereby greatly extending the light source. Life expectancy. Commonly used controllers on the market include analog controllers and digital controllers. The analog controllers are manually adjusted, and the digital controllers can be remotely controlled by a computer or other device. Simply put, the main function of the custom high purity KTP nonlinear crystal is to receive pre-defined various commands and setting parameters sent by the PC host, and process it through the main controller, and then control the LED light source through the driving circuit to realize digital PWM dimming according to the setting. The optical controller can be divided into a software part and a hardware part according to the architecture, wherein the software part can be further divided into a Pc end user interface application, a USB driver, and a controller hardware firmware. The hardware part can be divided into a main control module and an LED drive module. The main control module is mainly responsible for communication with the PC, command response, and transaction management. It is the core part of the entire controller.

Optical lens shape Machine vision is commonly used for fixed-focus lenses, and both are manually adjusted apertures. Generally, the aperture is not allowed to be automatically adjusted. There are two rings on the lens for focusing and dimming. To prevent accidental touch, the two rings of the zero order/multiple order/achromatic optical waveplate have locking screws. Note that the focus ring is not used to adjust the focal length, but to adjust the image distance to ensure that the clear image falls on the focal plane. Common optical lens parameters: focal length Focal length is a commonly used parameter for lenses. The lenses used in our packaging inspection series are available in 3.5mm, 4mm, 6mm, 8mm, 12mm and other specifications (1/3mm CCD standard lens is 8mm). Use a 28mm wide-angle lens (the standard lens of the line scan camera is about 40mm). The smaller the focal length, the better the lens, the higher the price, the more the edge deformation and other problems, so try to use the standard lens, the cost is higher. Common lens parameters: aperture Aperture is a device for controlling the amount of light that passes through the lens and enters the photosensitive surface of the body. Aperture f value = focal length of the lens / diameter of the lens aperture According to the formula, the smaller the aperture f value, the more the amount of light entering the same unit time. The aperture of each level is generally multiplied, for example, f8 is adjusted to f5.6, and the amount of light is doubled. The smaller the aperture, the larger the depth of field Increase the depth of field In our products, it is often required to increase the depth of field. For example, in the machine, the tobacco leaves are not completely in the same plane. Only by increasing the depth of field can the leaves at different distances be clear. Increasing the depth of field is only achieved by reducing the aperture, while reducing the aperture will also cause the image to darken, which requires an increase in illumination brightness. Common high precision optical waveplate parameters: resolution The lens resolution refers to the logarithm of black and white lines that can be distinguished within 1 mm of the image plane, in units of “pairs/mm”. The computar MP0814-MP lens on the strip detector is a megapixel lens with a resolution of 100 line pairs/mm. This resolution is higher. In fact, in addition to visual measurement, in fact, our products generally do not use such a high resolution. The higher the resolution of the CCD chip, the higher the resolution of the required lens. Common lens parameters: deformation rate The definition of deformation rate: two negative films, one is the negative film taken by the lens (the negative film 1), and the other is the standard negative film without negative film (the negative film 2). The two negative films have the same framing, the center is strictly consistent, first in the Determine the distance from the center point of the film (distance 1) on the film 1, then find the corresponding point on the film 2, and measure the distance from the point to the center point (distance 2), then: (distance 1 - distance 2) /distance 2 *100% All high-quality laser grade optical waveplate have deformation phenomena. They can be tested with a grid line template. In general, the lens with a shorter focal length has a higher deformation rate and a deformation rate of less than 2%. C interface: the lens reference plane to the focal plane (that is, the CCD target surface) is 17.526mm CS interface: the lens reference plane to the focal plane (that is, the CCD target surface) is 12.5mm Note: How the mechanical design determines the focal plane (that is, the CCD target surface) is generally 12.5mm or 17.526mm from the camera lens interface (depending on the camera interface type) Check the CCD manual to get the target size and position, and draw the position of the target on the CAD drawing. Find the center of the lens from the front of the target facing the front f (the focal length of the lens, for example 35mm) Connect to get the CCD's field of view If the field of view does not meet the requirements, you can achieve the goal by replacing lenses with different focal lengths. If the space of the video cabinet is not enough, you can use the mirror to adjust the actual position of the camera. When making the picture, you can use the mirror as the mirror for the central axis. Both ends of the mirror should extend beyond the ends of the field of view to ensure that the field of view is full of mirrors. The camera can't appear in the angle of view, otherwise it will block the camera's field of view. The mirror should not face upwards, otherwise it will be easy to fall. If it is necessary to face up, you must make a cover to seal the camera and mirror in the same closed body.
