Image Control Points Layout Method for UAV Monitoring of Road Subsidence in Mining Areas
In order to efficiently monitor the road subsidence caused by mining, this paper uses the UAV photogrammetry technology to study the effect of different image control point layout schemes on the monitoring accuracy of road subsidence at a working height of 50 m. In this paper, the method of combining simulation experiment and actual measurement verification is used to analyze the influ-ence of 10 different image control points layout interval on the subsidence monitoring accuracy, and a more reasonable image control point layout interval is 100 m, and the elevation monitoring accuracy is 1. 5 cm. Taking the cross road in the mining area of 9313 working face of Nantun Coal Mine, Jining city, Shandong province as the object to verify the simulation experiment results, the subsid-ence monitoring error is 1.6 cm. The results can meet the requirements of subsidence monitoring with centimeter-level accuracy, and provide guidance data for underground coal mining and road repair work.
