Zusammenfassung: | The invention discloses a steel box arch rib quality monitoring method based on BIM and 3D laser scanning. The steel box arch rib quality monitoring method comprises the following steps that first BIM three-dimensional models are constructed according to drawings and parameter information of all arch rib pre-assembled components; scanning each arch rib pre-assembled component to respectively construct a first point cloud model; performing primary fitting on the first BIM three-dimensional model and the first point cloud model, and judging whether the quality of the arch rib pre-assembled component reaches the standard or not; performing space operation on the first BIM three-dimensional model of each arch rib pre-assembled component to obtain a second BIM three-dimensional model of the arch rib segment; scanning the actually assembled arch rib sections to obtain a second point cloud model of the arch rib sections; and performing secondary fitting on the second point cloud model and the second BIM three-dimens |
