On Campus Building Modeling Based on the Terrestrial Three-dimensional Laser Scanning System

Based on the principles and characteristics of the terrestrial three-dimensional laser scanning system,this paper determines the technological process of campus building modeling,taking the administration building as the research object.It mainly studies the research procedures and methods of data collection by using terrestrial three-dimensional laser scanning system,and some key technologies such as noise removing,data registration and data reduction.It first makes the wire frame model of tested object drawing from feature line,then creates three-dimensional model by using 3DS Max.by which a digital campus can be realized.
