Abstract:
In order to solve the application problem of multi-view images for different mine monitoring requirement in UAV oblique photogrammetry, based on the characteristics of vertical and five-lens images, and the key techniques of oblique photogrammetry, by experiment of 3D model, digital orthophoto map(DOM), and digital surface model(DSM) production using vertical and five-lens images on five-lens UAV oblique photogrammetry system.The differences of geometric precision, characterization quality, and production efficiency of the results are compared in detail.The best application scheme in mine monitoring using two kinds of images for different needs is put forward.To be efficient and practical, the results show that when it is used to monitor the mining order of a mine and discover clues of illegal mining in a timely manner, vertical images production mode should be preferred; when it is used in mineral resources planning and obtain objective basic data, the production mode of five-lens images could be used preferentially.Through the experimental analysis, this article summarizes the different application programs, which has good practical value.
