Abstract
Visualization of the 3D point cloud model has played a crucial part in augmented reality and virtual reality for a long time. Besides, the technique of modeling also greatly benefit the application related to understanding crowd dynamics. In this paper, we introduce a technique to restore the the background area occluded by the front objects from a single viewpoint. In our procedure, we adopt the idea of exemplar-based in-painting and the surface detection method. We first detect the plane in the 3D point cloud model to help recover the depth map of the scene and reconstruct the geometric structure behind our target object. Further, we decide the colors of the hole on background which is resulted from the removal of the foreground object. At last, we rebuild the scene according to the inpainted RGB and depth images to achieve a more well-rounded visualization. We present several indoor examples with satisfying results.
