Abstract: With the in-depth development of open-pit mine,more slopes have been produced,which further increases the risk of landslide and collapse. Therefore,the deformation detection and stability analysis of slope is also a very important work in mine safety production. As a fast,simple and safe image acquisition technology,UAV tilt photogrammetry has been studied in the field of geological survey and so on. In this paper,UAV tilt shooting technology is used to realize slope inspection and replace or assist manual inspection,so as to ensure the work safety of inspectors,find and deal with the potential risks of mine slope in time.

Key words: open-pit mine, slope monitoring, UAV, tilt photography, model reconstruction
