Description
The application of monocular vision to measure the depth information of image feature points is one of the important tasks of monocular vision slam. Triangulation is a method often used to measure the depth information of feature points, but in the actual application process, the uncertainty of feature point matching will cause greater depth uncertainty. This paper proposes an improved ORB feature point extraction strategy, combined with the quad-tree model to achieve the homogenization of feature points. The feature points matching method uses the brute force matching method, RANSAC filters the matching point pairs, and obtains better matching results for depth estimation. Experiments show that the improved feature point extraction and matching method can effectively obtain camera pose estimation value and depth estimation value. And in this way, the accuracy of the estimated value is improved .
