Application of Vehicle-borne 3D Laser Scanning Technology in Large-scale Topographic Map Inspection
Traditional quality inspection data acquisition methods for large-scale topographic maps are generally network RTK,base station RTK,total station and other technologies. However,in complex urban environments,tall buildings,factory areas,etc.,these data acquisition methods have relatively low efficiency and obvious disadvantages. Through project case analysis,this paper finds that the data collected by vehicle-borne three-dimensional laser scanning technology,as compared with traditional measurement methods,not only greatly shortens the data quality inspection cycle,but also reduces the labor intensity of quality inspection personnel,and solves the problem of night optical mapping. The collected data can also be digitally visualized,the accuracy of the results in line with the "Basic specifications for surveying and mapping of national fundamental scale maps" in the accuracy measurement,planimetric ac-curacy and vertical accuracy requirements.
