Abstract
A novel stereo robot vision system using a two-layer liquid crystal display ( LCD ) is proposed. The images of an object captured by right and left CCD cameras mounted on the robot are displayed on the two-layer LCD. The light intensity transmitted through the LCD depends on the degree of matching, i.e., parallax, between the images of two cameras. Therefore, the distance from the cameras to the object can be deduced from the intensity of the transmitted light without using a sophisticated computer algorithm. An example of the application of this stereo robot vision system for the automated chasing by an autonomous robot is presented. According to the distance between the camera-mounting autonomous robot and an object ahead, the autonomous robot advances, stops, or retreats to maintain a proper interval between the object. In this paper, the ability for real time processing of the autonomous vehicle is shown by the experiments.
