Autofocus industrial cameras are generally installed on the machine assembly line to replace the human eye for measurement and judgment. The digital image capture target is converted into image signals and sent to a dedicated image processing system. The image system performs various operations on these signals to extract the target. characteristics, and then control the operation of the equipment in the field according to the result of the judgment.
1. Usually you first need to know the system accuracy requirements and camera resolution, you can use the formula:
X-direction system accuracy (X-direction pixel value) = field of view (X-direction) / CCD chip pixel number (X-direction)
Y direction system accuracy (Y direction pixel value) = field of view (Y direction) / CCD chip pixel number (Y direction)
2. Of course, the theoretical pixel value should be comprehensively considered by the system accuracy and sub-pixel method; then you need to know the system speed requirements and the camera imaging speed:
System single operation speed = system imaging (including transmission) speed + system detection speed
Although the system imaging (including transmission) speed can be theoretically calculated based on the camera's asynchronous trigger function, shutter speed, etc., the best method is to actually test it through software.
