Level of Detail-based 3D Space Point Cloud Streaming and its Evaluation

Developing an efficient quality control method for streaming a 3D space expressed by point clouds is mandatory. Based on this motivation, we develop a Level of Detail (LOD)-based quality optimization method for 3D space point cloud streaming. The proposed method adopts a 3D tile-based method and considers a distance between a user's viewpoint and a 3D tile (i.e., LOD) to maximize the user's perceptual quality. In the experiment, we capture an actual 3D space of our laboratory room using a LiDAR camera and conduct performance evaluations on the Unity platform. The results conclude that the proposed method achieves the highest perceptual quality.
