In this paper, we propose a 3D point cloud sequence compression algorithm based on inter-frame coding. First, we create an octree structure for the 3D point cloud. For the first frame, we compress geometric and color attributes through intra-frame coding. Then we apply inter-frame coding to the rest of the frames. We compress the geometric attributes using a dual octree and compress the color attributes using the k-means clustering. Both intra-frame coding and inter frame coding are performed with arithmetic codes. Experimental results demonstrate that the proposed algorithm compresses point cloud sequences more efficiently than the algorithm using only intra-frame coding.
