Application of Ground-based 3D Laser Scanning Technology in Engineering Surveying

Abstract

In this paper, the technological process of fixed ground-based 3D laser scanning technology in practical production of engineering survey is introduced, and application methods of the technology in topographic map surveying and mapping, earthwork calculation, road surveying, 3D modeling and other aspects are systematically discussed. Meanwhile, the paper summarizes the advantages and disadvantages of this technology compared with traditional surveying and mapping methods, discusses the application direction and prospect of ground-based 3D laser scanning technology in the future11, and provide a reference for the application of this technology in urban engineering surveying.
