Precautions for selection of industrial cameras Color mode determination: According to the application scenario, black and white cameras can usually meet most needs. If color image measurement and analysis are involved, color cameras are selected. Resolution adaptation accuracy: Selected according to the measurement accuracy and field of view of the target object. The camera resolution (length × number of pixels) should be at least equal to the field of view (length × width) divided by the accuracy, for example, the detection accuracy is 0.01mm, the field of view is 21mm×16mm, the camera resolution should reach (21/0.01)× (16/0.01), about 3 million pixels, and you can choose 5 million pixels or above cameras for higher quality. Frame number matching motion target: When the object to be measured is in a state of motion, choose a high-frame number industrial camera, but generally the higher the resolution, the lower the frame number, and the relationship between the two needs to be balanced. The frame rate determines the test efficiency. For example, a 30FPS camera can take up to 30 shots per second, and a 120FPS camera can take 120 shots per second. Output interface selection: The performance of interface buses such as Camera Link, USB3, GIGE, etc. will affect the frame rate. Among them, Camera Link has the best performance and needs to be selected based on actual needs and device compatibility. Exposure time control: The minimum exposure time determines the maximum speed of the target movement. Before selecting the model, you must consider the target movement speed to avoid blurring of the image due to improper exposure time. Sensor Type and Size: Static Targets Optional Roller Blind CMOS Camera Reduces Cost, Dynamic Targets Prioritize Global CMOS or CCD Camera. The larger the sensor size, the larger the pixel photosensitive area and the higher the image quality. At the same time, the sensor chip size must be less than or equal to the lens target size.
