Abstract:
For controlling an autonomous vehicle, a novel stereo robot vision system using a two-layer liquid crystal display ( LCD ) is proposed. Images of an object captured by right and left CCD cameras mounted on the vehicle are displayed on the two-layer LCD. The intensity of the light transmitted through the two-layer 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 sophisticated computer algorithm. An example of the drafting is shown; according to the distance from the autonomous vehicle to the other vehicle driving ahead, the autonomous vehicle advances, stops or retreats for keeping proper following distance.
