Robotic visual inspection system is to use robot instead of human eyes to make a variety of measurement and judgment. In general, the robotic visual system includes an illumination system, camera lens, camera system and image processing system. For each application, we need to consider the system operation and image processing speed, to choose a color or black and white camera, and other actual details.

From the functional point, a typical robotic visual system can be divided into: image acquisition, image processing and motion control.
