With the development of digital twin technology and the improvement of indoor high-precision positioning accuracy, industrial plants, transportation and other industries have more and more demands for 3D display of indoor scenes. In order to meet the needs of China Mobile in the field of Indoor 3D map, industry-based technology solutions are used to build indoor 3D map capability and provide diversified map capability support.
The first is indoor point cloud processing and 3D modeling. The infipoints platform is used to preprocess, automatically extract and model the imported point cloud, and output 3D models and visual browsing files. The platform has the functions of creating textures, interference checking, 2D line drawing, etc. for the models. The second is the production of indoor Panoramic Map, which makes and publishes the panoramic image output by infipoints.
