To overcome the difficulty of deploying control points in complex geological environments, this paper presents a point cloud registration method using stable rock features as constraints. Stable rock patches are extracted based on local geometric and reflectance attributes. Coarse registration is performed via feature point matching on rock surfaces, followed by fine registration using the point-to-plane ICP algorithm. Experimental results indicate that this method effectively reduces registration errors induced by geological deformation, offering significant theoretical and practical value for improving deformation monitoring accuracy and analysis.
