The invention discloses a BIM (Building Information Modeling) three-dimensional reconstruction method for a steel structure factory building. The method comprises the following steps: constructing a steel structure factory building key site visual identification network; constructing three-dimensional coordinate data of key sites of the steel structure factory building based on the visual identification network; obtaining a sparse point cloud model based on the constructed three-dimensional coordinate data of the key site, and constructing a three-dimensional model of the steel structure factory building based on the sparse point cloud model; and triple information is extracted from the engineering file based on the knowledge graph, and the extracted triple information and the constructed three-dimensional model of the steel structure factory building are combined to jointly construct the BIM model of the steel structure factory building. According to the method, for the steel structure factory building of wh
