“…Applications of 3D information have extended from digital elevation model (DEM) and digital surface model (DSM) generation to many other fields including archeology [1,2], topographic monitoring [3,4], facial geometry and dynamic capture [5,6], cultural heritage protection [7,8], forest and agriculture modeling [9,10], and medical treatment [11]. Since laser scanning can produce highly accurate, reliable, dense, and more integrated 3D point clouds of objects [12], it has been utilized as the preferred technology for 3D modeling over the last two decades.…”
