Abstract :
Geospatial information technology has been the research hotspot around the world nowadays, 3-D digital city is the highest priority of it. More and more city digital information is needed. In this paper we present a mobile mapping system for three dimensional environment modeling which consists of an instrumented vehicle equipped with 2D laser range scanners for data mapping, frame CCD for color stereo images, and POS/LV for vehicle positioning and attitude information. The advantage of this system is its ability to perform distance and color data acquisition at same time during the vehicle navigation. This system integrates the laser scanner data and stereo images with the POS/LV system and is capable of reconstructing the 3D geometry of the environment.
