The message analysis method of binocular camera is that binocular camera shoots left and right images in the same scene, and uses stereo matching algorithm to obtain parallax map, and then obtains depth map. Binocular camera uses the principle of bionics to obtain synchronous exposure images through calibrated dual cameras, and calculates the third depth information of pixels in 2D images. In order to monitor different environmental occasions, a new adaptive recognition algorithm based on binocular computer vision is proposed.
