Abstract

The acquisition of the spatial data is a fundamental problem in multi-dimensional and dynamic GIS construction and infrastructure. Ground-based mobile Laser scanning System, which is mainly used in the reconstruction of 3D city and acquisition of local region geographic information, has an important function in rebuilding 3D spatial object. This integrated systems have the same sensors GPS/INS for positioning. In this paper, our researches are focused on multi-sensor integration without GPS/DGPS/INS. The application system we developed is a ground-based motive platform, upon which multi-sensors were integrated. In system, a relative positioning sensor we employed is the Rotary Encoder, which determines the relative positions of the platform from original position and the Laser Scanner’s posture. The Laser Scanner surveys the distances between the platform and the object. All data were transferred through wireless cable into the server located in the office. The wireless modem we applied provides reliable wireless data communication for either point-to-point or multipoint applications. In this paper the outline of system, principles and algorithm are presented. Moreover, some trials and experiences are presented in this paper. Finally some conclusions and further research work are introduced.
