We conduct research on the photogrammetry technology of coal mine slopes,elaborate on the principle of drone photogrammetry,and analyzes the process of drone photogrammetry.Based on the actual situation of the slope,the selection and parameter selection of drone equipment have been completed.Based on the model generated from the first shooting,the extracted fixed landmark coordinates are used as the initial coordinates of the slope and compared with the coordinates of subsequent models.The results indicate that the drone photogrammetry has low error values and high measurement accuracy.Compared with traditional measurement methods,drone photogrammetry technology has the characteristics of high accuracy,high efficiency,and wide applicability,and has achieved good application results in open-pit coal mine slope monitoring.
