Abstract: The indoor mobile measurement system plays an important role in the spatial entity construction of the new basic surveying and mapping system in Beijing. This paper proposes the technical framework of the indoor mobile measurement system in the spatial entity construction of the new basic surveying and mapping system, which includes indoor external data collection, processing procedures and methods, multi-source point cloud data splicing and fusion and integrated point cloud and panoramic image data application in all-element 3D modeling. NavVis M6 indoor mobile measurement system is used as the experimental equipment, and Huairou district is selected The area of BBMG cement plant is a pilot area for the development of Beijing's new basic surveying and mapping. The experimental results show that the operation process of the indoor mobile surveying system proposed in this paper can meet the needs of the spatial entity construction of the new basic surveying and mapping system.

Key words: new basic surveying and mapping, 3D laser scanning, indoor mobile measurement, SLAM, multi-source fusion, all-element 3D modeling
