Non-learning Stereo-aided Depth Completion under Mis-projection via Selective Stereo Matching

Yasuhiro Yao, Ryoichi Ishikawa, Shingo Ando +4

We propose a non-learning depth completion method for a sparse depth map captured using a light detection and ranging (LiDAR) sensor guided by a pair of stereo images. Generally, c…
