Abstract

In stereo vision, depth information is one of the important parameters to understand the real world. One method for extracting such depth information is based on the geometry of stereo vision using two cameras displaced from each other by a baseline distance. In this paper, we show an improved triangulation method based on stereo vision angles. We setup a stereo vision system which extracts the distance to the object by detecting moving objects using difference image and by obtaining depth information using the improved triangulation method It has been implemented employing a TMS320C30 DSP board in a stereo vision system. As a result of experiment, the proposed vision system has the accuracy of 0.2mm in the range of 400mm.
