Application of handheld three-dimensional laser scanner and mobile backpack scanning system in integrated measurement of buildings and buildings

Yu Long   Dai Longchang   Shi Zhiling  
[Abstract]: Due to the influence of signal interference, 3D laser scanner with GPS can not acquire 3D data completely and accurately in the process of data acquisition. In this paper, the same data source format of different equipment is used for 3D data acquisition. Combined with the handheld three-dimensional laser scanner (blk2go) and the mobile backpack scanning system (Pegasus backpack), the 3D data of HAMA group house in Shuanglong street, Panlong District, Kunming City were collected. Based on the point cloud data of mobile backpack scanning system, the point cloud data of hand-held three-dimensional laser scanner are fused to obtain the complete three-dimensional point cloud of the target in the survey area, and carry out digital mapping. Practice has proved that the combination of the two systems can provide reference for data acquisition of similar projects in weak GPS signal survey area.
