Research on the application of new surveying and mapping technology in the surveying and mapping of large scale topographic map of mine
This paper first introduces the oblique photography technology and Lidar technology,and then analyzes the application process of the two new technologies in the mapping of large-scale topographic maps in mines.Finally,the two technologies are combined in the mapping of large-scale topographic maps in a mine,and the accuracy of the topographic maps is tested with detection points.Through the analysis of the test results,it can be seen that the accuracy of the topographic map produced by the scheme in this paper can meet the accuracy requirements of 1∶500 topographic map in mines,and it has high efficiency and low cost,and has certain popularization and application value.
