Further, the output end of the laser mapping planning platform is connected with a mapping model planning module 60, and the mapping model planning module 60 is used for positioning the mapping position of the mapping instrument and binding with the mapping result. When the method is specifically used, since model planning is carried out in the later stage and the building assembly process is carried out, in order to determine the positions of all assembled components, the vacant spaces of all areas of a mapping model are required to be determined, in order to ensure the reasonable allocation space of the final building assembly, mapping positions of mapping instruments are positioned through the mapping model planning module 60 and bound with mapping results, the detection results of different mapping areas are determined, space planning is carried out from multiple angles, and all building spaces are reasonably allocated.
