Binocular stereo vision ranging method taking contour boundary center of measurement object as matching features was investigated. And experimental platform for binocular stereo vision ranging system was built up. The stereo vision ranging system comprised four modules: camera calibration, stereo calibration, stereo rectification and features extraction. Firstly, the intrinsic parameters of single camera were obtained by camera calibration and relative pose of two cameras was obtained by stereo calibration. Then the left and right images were rectified into a frontal parallel arrangement by Bouguet’s method. The edge pixels of contours were detected by image processing. Then the disparity and the distance was calculated taking contour center as matching features. Finally, measurement error analysis was performed to verify the proposed method with good practicability.

Camera calibration is the most important stage of machine vision measurement. The principle and method of camera calibration for binocular stereo vision system are introduced and the left and right CCD are respectively calibrated by using the prepared calibration target and the MATLAB program. Then internal and external camera parameters are obtained by the calibration experiments. The experimental results show that the calibration results have high precision.

Measuring Experiment

The intelligent Aim system of the Tear Bomb Emitter based on binocular stereo vision has been designed for the armored car equipped in our Armed Police Force. In this paper, according to the intrinsical feature of the background, the binocular stereo vision is chose to detect the forward distance between the bomb emitter and the crowd which the emitter needs to aim at. A new way which is based on integrating temporal information with spatial information has been presented. Then the forward distance was obtained according to the camera calibration, image processing, and error model. The error and measuring experiment shows that the percentage error is less than 2% and this method is feasible and effective.
