Paper Abstract

Aiming at the problems of low accuracy, low positioning accuracy and low efficiency of feature points extraction in existing binocular vision positioning methods, and classical Harris corner detection algorithms depending on the selection of experiential threshold and the setting of corner points extraction, a corner detection algorithm based on PSOHarris operator to detect the double threshold is proposed in this paper, which calculates the optimal threshold by dynamic iterative optimization of the threshold. On this basis, the feature point parallax is calculated to match the image features, and the coordinates of the world coordinate system are calculated according to the coordinates of the target point. The comparison experiments show that the algorithm effectively improves the positioning accuracy and efficiency of feature point extraction.
