Stereo matching method and system based on binocular camera

The invention discloses a stereo matching method and system based on a binocular camera. The method comprises the following steps: collecting continuous multi-frame left and right eye images in a target area; performing parallax matching cost calculation on the left eye image and the right eye image to obtain a plurality of parallax matching cost values; aggregation in multiple directions is carried out on each parallax matching cost value, and calculation is carried out through argmax (maximum independent variable point set) to obtain a parallax map corresponding to the maximum parallax matching cost value; and carrying out normalization processing on the disparity map, and carrying out sub-pixel disparity calculation to obtain a stereo matching result. According to the method, effective deployment in a deep learning chip is realized, time and effects are met, the method has better generalization ability, the effect in sub-pixel precision is better, and the algorithm precision and generalization ability of s
