Abstract

The invention discloses a binocular stereo matching method and a binocular stereo matching system based on dense network depth learning. Firstly, stereoscopic image pairs with real values are preprocessed to construct training samples for network learning. Then a dense convolution neural network model is trained to calculate the matching cost. Finally, cross-aggregation algorithm is used to optimize the matching cost, and the optimal disparity is calculated by WTA strategy, and the corresponding disparity map is obtained. A method for extracting features of convolution layer features that a dense convolution neural network model is used to extract features of convolution lay, Attempt to find a better matching cost, effectively solve the problem that pixel matching point can not be found accurately in weak texture region and the performance of detail features is poor, with higher computational accuracy and better robustness.

Description

technical field [0001] The invention relates to the technical field of image sequence stereo matching, in particular to a binocular stereo matching method and system based on dense network deep learning. Background technique [0002] Stereo matching is the process of finding the same feature point from the left and right images and calculating its disparity. A classic stereo algorithm is summarized in four steps: matching cost calculation, cost aggregation, computing disparity, and disparity refinement. With the substantial improvement of computer software and hardware levels, stereo matching technology has gradually become a hot research direction in many fields such as computer vision, image processing and pattern recognition, and its research results are widely used in many fields such as robotics, military, aerospace, medical information Fields, such as unmanned automatic driving systems, robot vision systems, drone navigation and take-off and landing systems, industria...
