Abstract: Most of the existing 3D geometry compression algorithms employ two strategies: successive quantization and predictive coding, and induce accumulative error. The accumulative error is mainly caused by the inconsistency of values at predictive vertexes in predictive coding. In this work, we propose a novel approach to eliminate the accumulative error. The new approach employs a set of reference planes instead of predictive vertexes in coding. The values of the reference planes maintain consistency in coding, so the accumulative error can be eliminated efficiently. Both theory and experiments show that this approach can achieve higher precision and less distortion without reducing the compression ratio and processing speed. The approach is also compatible with most of the existing compression algorithms.
