What should I pay attention to when choosing a camera and lens for machine vision inspection equipment?

The lens is the eye in the field of machine vision. It has been playing the role of the eye since the detected object. The detection situation is fed back to the industrial camera. The lens is a high-performance resolution lens and adopts ultra-low distortion design technology to reduce the distortion rate. Reflect the image effect more realistically. Because the distortion technology can effectively reduce the reflection loss of the lens, reduce glare, increase the contrast, effectively improve the color reproduction, and improve the clarity of the image. The quality of machine vision cameras and lenses directly affects the performance of machine vision inspection equipment. Choosing a good machine vision camera can improve the overall performance of the machine vision system. What should I pay attention to when choosing a camera and lens for machine vision inspection equipment? Choosing a machine vision lens should follow the following principles: 1. Spectral characteristics of the lens; 2. What kind of interface type is the camera, C interface, CS interface or other interface; 3. Field of view of the lens 4. The working distance of the lens 5. Lens distortion rate 6. Lens mechanical structure size 7. What is the chip size of the matching camera? When choosing a CCD camera, the following aspects should be considered: 1. Video features; including dot frequency and line frequency 2. The working mode of the camera: continuous, trigger, control, asynchronous reset, long time integration 3. Video parameter adjustment and control method: Manual, RS232 4. Signal output interface 5. Type of photosensitive chip; CCD or CMOS At the same time, when choosing CCD, it should be noted that l inch = 16mm instead of equal to 25.4mm.
