Specialized classification of camera systems and image processing equipment that realize visual recognition functions for industrial robots. Includes CCD cameras, CMOS cameras, 3D vision sensors, laser displacement sensors, image processing controllers, lighting equipment, and lenses. Used for automation tasks such as workpiece position detection, quality inspection, dimensional measurement, color discrimination, and character recognition, functioning as the 'eyes' of robots. Unlike simple proximity sensors or photoelectric sensors, these are advanced vision systems that analyze image data to control robot operations. Achieves improved accuracy and labor reduction in assembly lines, inspection processes, and picking operations.
