Dual-TOF camera depth information acquisition method adopting binocular principle

The invention provides a dual-TOF camera depth information acquisition method adopting a binocular principle, and relates to an image processing technology, and the method comprises the steps: processing a left TOF depth map and a right TOF depth map to obtain a TOF depth map, carrying out the noise reduction of the TOF depth map to obtain an initial depth map, and obtaining a parallax image according to a left TOF light intensity gray-scale map and a right TOF light intensity gray-scale map; obtaining a TOF depth map credibility weight function based on the TOF depth map, obtaining a stereo matching depth map based on the parallax image, and obtaining a credibility weight function of the stereo matching depth map; enabling the TOF depth map and the stereo matching depth map to be subjected to pixel-level fusion processing based on the TOF depth map credibility weighting function and the stereo matching depth map credibility weighting function, and obtaining the target depth image.
