Abstract:

3D laser scanning technology has been successfully applied to static surface measurement because it can measure 3D coordinate with high speed, high precision and high density to describe the surface detail. At present, the deformation analysis of the landslide surface is carried out mainly with some observed characteristic points by GPS or total station, but because of few data, this analysis is not complete. The detailed deformation of landslide has an important role for the correct deformation analysis. To introduce this technology to the landslide monitoring is significant for detailed deformation analysis, if a lot of natural rocks are used as monitoring points. In this paper, the theoretical analysis and the practical tests have been carried out; and the preliminary result has been obtained.

Key words: 3D laser scanning, landslide monitoring, deformation computation, deformation analysis
