“…Presently, the acquisition and processing of 3D data have become key technologies [ 1 , 2 ]. These technologies play a crucial role in various fields, including innovative basic surveying and mapping [ 3 , 4 , 5 ], the creation of high-precision maps for autonomous driving [ 6 , 7 , 8 , 9 ], geological landslide monitoring [ 10 , 11 ], and the preservation of cultural heritage [ 12 , 13 , 14 , 15 , 16 ]. Point cloud data, as a primary form of 3D data, are highly favored for their ability to precisely depict the physical space’s shape and structure.…”
