Target height measurement method based on stereo vision

摘要

The key to using binocular stereo vision technology to achieve target height measurement is to obtain accurate predicted box of target. We propose a disparity-method and an edge-method to correct the original predicted box of the target. The main idea of the disparity-method is to use the disparity discontinuity between the target area and the background to find the location of the highest point of the object, so as to correct the upper edge of the original predicted box. The main idea of the edge-method is to find the boundary between the target and the ground based on the edge map, so as to correct the lower side of the original predicted box. It can be seen from the experiment that the corrected predicted box has higher accuracy than the original predicted box obtained by Yolo. Finally, we give a specific method for measuring the height of the object based on binocular stereo vision.
