3D scanning reverse modeling method based on point cloud data

The invention discloses a 3D scanning reverse modeling method based on point cloud data. The 3D scanning reverse modeling method comprises the steps of obtaining 3D scanning point cloud data of each component unit of an equipment module; establishing a unit 3D model of each component unit according to the 3D scanning point cloud data, and performing detection and model adjustment on the unit approximation degree; acquiring an assembly sequence relationship of each component unit of the equipment module, and sequentially numbering each unit 3D model according to the assembly sequence relationship; sequentially performing 3D model assembly on each unit 3D model according to the serial number to construct an equipment 3D model of the equipment module; performing equipment similarity detectionand model adjustment on the equipment 3D model and the equipment module; preserving equipment 3D models. According to the 3D scanning reverse modeling method based on the point cloud data, three-dimensional modeling can be c
