Title:
BINOCULAR STEREO MATCHING METHOD, COMPUTER STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/241374
Kind Code:
A1
Abstract:
Provided in the present invention are a binocular stereo matching method, a computer storage medium, and an electronic device, the method comprising: projecting a light beam to a calibration plate by means of a projector; then collecting a first plane graph and a first phase graph of the calibration plate by means of a left camera, and collecting a second plane graph and a second phase graph of the calibration plate by means of a right camera; determining a mapping relationship among the left camera, the right camera and the projector in a pixel coordinate system according to the first plane graph, the second plane graph, and the first phase graph and/or the second phase graph; and finally, according to the mapping relationship, acquiring a matching initial value. In the present invention, the initial value of binocular stereo matching is deduced by means of calibration, so that a matching result can be obtained simply by performing fine matching in a small range near the initial value. In this way, a matching range can be greatly reduced, thus increasing the matching speed, lowering memory demands of computation, reducing the impact of noise on a matching result, and improving the matching effect.
