This paper introduces three laser ranging principles widely used in three-dimensional laser scanning system based on the working principle of three-dimensional laser scanning technology. By comparing the mainstream equipment parameters in the market, we can find the technical gap between domestic and foreign counterparts. This paper focuses on the introduction of the overall working process of three-dimensional laser scanning, including the development of scanning plan, field data acquisition and internal data processing, and the introduction of relevant technical details. Finally, the existing problems of three-dimensional laser scanning technology are summarized and the preliminary countermeasures and Suggestions are given.
