Abstract
In order to solve the problems existing in mining area subsidence monitoring,such as large amount of measurement work,complex operation,low monitoring frequency and image resolution,and low accuracy of collected data,we proposed a mining area subsidence aerial photogrammetry method based on PPK differential technology.We used UAV terrain following technology to collect the image data of mining area,used PPK differential technology to obtain the image geographical location elevation information,and synthesized them into the dense point cloud.Then,we used the adaptive irregular triangulation algorithm to filter the discrete points in the dense point cloud,and used the local polynomial spatial interpolation method to build the subsidence basin DEM model of target mining area,realizing the aerial photogrammetry of mining area subsidence.The experimental result shows that this method has high measurement accuracy,accurate positioning,flexible,efficient and easy operation,and can monitor the subsidence of mining area as a whole.The subsidence basin model built by this method has high fidelity,and very clear visual effect,which can better analyze and study the subsidence law of mining area.关键词
