The development of the linear matrix CCD test system based on the single chip machine

Published:2011/8/23 22:39:00 Author:qqtang | Keyword: linear matrix, CCD test system, single chip machine

Let's assume to set a white line(the width is 300mm) on a plate of deep color (e.g black, blue and green, etc) as the moving track outgoing line of the robot, the test system of the white track is developed by using the linear matrix CCD. We first image the road information on the CCD sensitivesurface by using the optical system camera; and then the white line position is read out as the vision sense of the robot which is controlled to move along the white line. This is a typical CCD time test system.   (View)
