Abstract :
This paper presents a method to solve the correspondence problem in matching the stereo image using Sum of Absolute Differences (SAD) algorithm. The computer vision application in this paper is using an autonomous vehicle which has a stereo pair on top of it. The estimation of range is using curve fitting tool (cftool) for each detected object or obstacles. This tool is provided by Matlab software. The disparity mapping is produced by block matching algorithm Sum of Absolute Differences (SAD). The range determined by cftool will be used as a reference for navigation of autonomous vehicle. The process of camera calibration, image rectification and obstacles detection is also discussed in this paper.
