How to choose the right industrial camera for industrial vision inspection
1. Choose CCD or CMOS camera according to different applications. CCD industrial cameras are mainly used in image extraction of moving objects, such as machine vision for placement machines. Of course, with the development of CMOS technology, many placement machines are also choosing CMOS industrial cameras. CCD industrial cameras are generally used in visual automatic inspection schemes or industries.
2. The choice of resolution First consider the accuracy of the object to be observed or measured, and select the resolution according to the accuracy. Camera pixel accuracy = size of field of view in one direction / resolution of camera in one direction. Then the resolution of the camera in one direction = the size of the field of view in one direction/theoretical accuracy. In this way, the camera requires a resolution of 1000 in one direction, and it is enough to choose 1.3 million pixels.
3. The size of the sensor chip that matches the lens needs to be smaller than or equal to the size of the lens, and the C or CS mount should also match (or add an adapter).
4. Camera frame number selection When the measured object has motion requirements, an industrial camera with a high frame number should be selected. But generally speaking, the higher the resolution, the lower the frame rate.
