Abstract
In modern urban planning and construction,more and more attention has been paid to the effective use of underground space,especially the construction of underground parking lots,which solves the problems of ground traffic congestion and parking difficulties.Three-dimensional laser scanning technology,or LiDAR technology,provides a high-precision and efficient terrain mapping method that enables rapid data acquisition and accurate spatial analysis in complex underground environments.This paper first introduces the basic principles of 3D laser scanning technology and its application in topographic surveying,and then expounds in detail the design requirements of underground parking lot topographic maps and the selection criteria of 3D laser scanning equipment.The article also describes in detail the data acquisition process,data processing and topographic map generation steps,and verifies the effectiveness of the method through technical testing,demonstrating the practical application and potential advantages of 3D laser scanning technology in underground parking lot surveying and mapping.关键词
