| Abstract: | The vehicle-borne laser mapping system(VLMS) integrates laser scanners,GPS,INS and odometer and CCD cameras by controlling system,so as to form a complete and highly effective vehicle mapping system.We discuss about the structure of the presented system,and the principles of sensor,positioning device and controlling system and date process.It was applied in water conservancy engineering with advantages of automation and high precision.The positioning error of GPS reaches centimeters level,while 3D laser scanning reaches resolution level of millimeters,thus digital 3D modeling for dikes can be realized. |
