Abstract

We have developed the wide and narrow dual image guidance system for ground vehicle on fast focusing and stereo matching operation. The fast focusing catches the distance information of outside world. The stereo matching operation on the focused two wide images finds the characteristic position to detect the fine distance information through the fast focusing using the narrow images due to the camera with the long focal length. Our fast focusing algorithm works precisely on the differential image such as the Daubechies wavelet transformed high pass image, the Roberts image, Prewitt image, Sobel image and the Laplacian image. After the stereo matching operation on the focused wide images, the two cameras serves the narrow image focusing operation. This procedure establishes the reliability of the detection of the object and gives the fine image information of the object. The pointing operation of the long focal length camera of the narrow image uses the related pixel address information due to the stereo matching and the 2 axes gimbal equipment of the precise resolution. We experimented the detection of the object by stereo matching and ranging the fine distance by narrow image focusing. The experiment gives the appropriate detection and fine pointing of the narrow image focusing to meet the guidance capability of the ground vehicle.
