Abstract

Commodity-level scan cameras generally capture RGB-D image with depth missing or incorrect depth points if the surface of the object is transparent, bright, or black. These incorrect depth points are generated randomly and limit the downstream applications of raw RGB-D images. In this paper, we propose a coarse-to-fine method to detect and eliminate the incorrect depth points via RGB semantics. In our flowchart, deep learning-based networks are applied to predict the potential regions with incorrect depth points and the normals of the point cloud. Then we develop a three-step elimination method to remove the incorrect depth points in the regions. Experimental results show that our method leads to great improvements for downstream applications of RGB-D images, especially in depth completion application.
