Abstract

At first, the paper introduces a non-contact measuring system with a new proximity sensor researched by South China University of Technology and its constitutions. The measuring system not only has high measuring precision but also could obtain 3D coordinates and normal vectors compared with common measuring systems. The paper puts forward two new data-compressing algorithms according to its measuring characteristics, the one is based on dichotomy and the other is based on quadrangle. They are all own the advantages of simple theories, high calculating speed and large compressing ratio. The former is fit to deal with smooth measured surface with less measuring points. The later can do data compressing according to surface varying current which is fit for compressing scanning data of complex surface especially; at the same time, it can homogenize measuring data and improve data processing speed and nicety.
