Application of SLAM 3D scanning in surveying and mapping of illegal construction
Compared with the traditional surveying and mapping technology,simultaneous localization and mapping(SLAM)three-dimensional(3D)scanning technology has the characteristics of high efficiency and precision,complete and diversified data,and non-contact acquisition.It is widely used in engineering fields such as topographic surveying and mapping,building surveying,area measurement,and earthwork calculation.Taking the illegal construction surveying and mapping project as an example,this paper analyzed the working principle,operation process,and key technologies of the SLAM 3D scanning system.According to the data requirements of illegal construction management and later treatment,this paper summarized the main idea of point cloud data processing and the output of the result map and verified and counted the precision of SLAM 3D scanning data on site,so as to provide a reference for the design and implementation of future projects.
