Optimization of the Feedback and Control Module for Light Source of High-Speed Vision Inspection System

Abstract:

The situations of insufficient or too much exposure of lights often happen in high-speed vision inspection system. In order to improve the ability to adapt to environment, the feedback and control system is used. If we use the processing method of integral threshold value, the control of light source wont work. Besides, the former feedback system has the stoboflash problem, so optimization design is needed. A new feedback signal extraction method is put forward and the program of source control is optimized, and the adaptability of the diction system to the change of the environment light is improved, it works out the function of controlling the LED light source automatically and steadily under the effects of environment light and the problem of stroboflash.
