Implementation of Real-Time Stereo Matching System Based on Speckle Structured Light

Real-time and accurate acquisition of target depth information is the prerequisite for subsequent 3D reconstruction and abnormal behavior detection. For this application, this paper designs and implements a binocular stereo real-time system based on speckle. The main hardware components are binocular and speckle projector, and the main algorithm is (Semi-Global Matching) SGM's GPU implementation. The detection range of the system is 1.2m-6m, the frame rate can reach 30, the parallax level is 256, and the image resolution can reach 1280×720 pixel.
