Research on calibration technology of vehicle laser scanning system

With the development and maturation of GPS technology, inertial navigation technology, CCD imaging and laser scanning technology, vehicle movement measurement technology has become a trend of urban spatial information acquisition. In the process of the vehicle to improve the measuring precision, the calibration field layout processing is particularly important. This paper takes Daxing Campus of Beijing University of Architecture calibration field as an example. According to the established calibration mathematical model, use control point calibration method. The error equation is established and the algorithm is realized by programming. The attention of control field layout fully described, and the acquired data is processed. At the end of the 3D laser scanning system of vehicle after calibration is making accuracy analysis.
