Application of Point Clouds from Terrestrial 3d Laser Scanner for Deformation Measurements

3D laser scanning technology has become an exciting and beneficial alternative in the collection of as-built data for plant and facilities applications, where accurate three-dimensional detail of complex facilities is critical for efficient design and construction projects. This paper introduces terrestrial 3D laser scanner as an instrument for two experiments which may be applicable to the field of deformation monitoring. Firstly, results of a Landslide experiment are presented, with Fujiayan Landslide in Wanzhou district in Chongqing as a case study area, investigates the method on high resolution and accuracy DTM generation. Secondly, results of a deformation monitoring experiment are presented. In this instance, a deformation monitoring for the side slope of metro in shenyang within a controlled environment. This forms the basis of a preliminary investigation into the viability of using a laser scanning instrument for deformation measurements. * Corresponding author
