Abstract – Object distance measurement is becoming more and more important in mobile autonomous systems. Information of the distance of objects are useful for navigation and avoidance of autonomous mobile systems. The system can easily avoid obstacles if the accurate position of obstacles can be acquired. With the advancement of technology, the stereo vision technology has become more and more mature. Many related applications have hence emerged, such as 3D movie, face recognition, obstacle detection and recognition. Previous research works have obtained object distances from images using one vision sensor. For example, in, the system utilized a single camera and a laser pointer to obtain distance measurement. Hai-Sung Baek et al. discussed the differences on crossing camera setups and parallel camera setups. They also suggest a method to measure the distance when an object is located outside the optical axes in the overlapping area of two cameras.

Keywords— 3D images; parallel camera; navigation; obstacles; stereo vision technology
