Underwater cave mapping using stereo vision
WebIn this paper, we propose an underwater real-time 3D reconstruction system based on stereo camera. Aiming at the problem of blurred underwater images, we propose a lightweight image enhancement algorithm. For the problem of real-time point cloud generation, we adopt the method of computing disparity maps by using stereo cameras. WebThis work presents a systematic approach for 3-D mapping and reconstruction of underwater caves. Exploration of underwater caves is very important for furthering our …
