Abstract：The stabilityofrock slope isa key control factor for the construction and operation of major projects，and the traditional monitoring methods have problems such as low effciencyand limited coverage.In this study，UAV photogrammetry technology was inovativelyused，combined with motionrecovery structure（SfM）and multi-view stereo vision（MVS）methods，toconstructa high-precision 3D terainmodel，whichrealizedtheaccurate monitoring of the surface displacement of rock slopes with high steep fractures.Inthis study，the influence of the ground control point（GCP）layoutschemeon the reconstructionaccuracy was systematicallyanalyzed，and the 3D modeling process was optimized.Based onthe image corelation technology，COSI-Corr optimized the quantitative extractionmethodof horizontaland vertical displacementof land surface.Theexperimental resultsshow thatthe proposed method can obtain displacement monitoring results with centimeter-level accuracy，which provides a new technical means for early warning and has important engineering application value.
