Abstract

Monocular visual camera measurement can obtain the accurate pose information of 3D objects from a single image, but the pose ambiguity problem will inevitably occur when using the same method to process 2D object images. To solve this problem, this paper proposes a binocular vision method, using two pre-calibrated cameras to shoot the coplanar target from different angles at the same time, and matching the corresponding image points of the coding markers on the coplanar target. After obtaining the 3D coordinates of the coded points, the pose information of the target is calculated by Bundle Adjustment method. The experiment results show that this method can effectively solve the problem of pose ambiguity in monocular vision. Compared with other methods, the pose measurement method proposed is faster and more robust with larger coding capacity , more accurate positioning, and better comprehensive performance.
