Stereo Disparity Vision for Determining Object Contour Position
This study was aimed at determining the position of an object's contour using stereo vision. A stereo disparity algorithm, which functionally consists of scene reduction, epipolar line selection, and features matching, was implemented. Measurement inaccuracy arises generally from three sources: camera imaging resolution, camera focal length inaccuracy, and camera-to-camera distance error. An error analysis was performed which shows that camera imaging resolution is the major source of inaccuracy.
