Building component assembly analysis method and system based on point cloud wireframe constraint

The invention discloses a building component assembly analysis method and system based on point cloud wireframe constraint, and relates to the related field of building construction pre-assembly, and the method comprises the steps: obtaining the position parameters of a sampling measurement device; performing data acquisition of the building component through the sampling and measuring device to obtain a point cloud data set; obtaining wireframe data of the building component, and performing point cloud constraint processing according to the point cloud data set, the wireframe data and the position parameters to obtain a processed point cloud data set; according to a fabricated building model component library and the processing point cloud data set, constructing a fabricated building BIM model; and importing the fabricated building BIM model into Geomagic Control, performing comparison by setting a reference model, and outputting an assembly analysis result. The technical problems of high cost, long consumed
