The invention discloses a factory building structure restoration method based on three-dimensional laser scanning and BIM reverse modeling. The method comprises the steps that site investigation is conducted on a factory building, and factory building data are scanned through three-dimensional laser; carrying out point cloud splicing processing on the scanning data, uniformly registering the scanning data into the same coordinate system, and carrying out point cloud denoising processing to obtain a point cloud model; the method comprises the steps of obtaining point cloud data based on a point cloud model, analyzing and processing the obtained point cloud data through BIM software, performing reverse upset to form a reverse upset model based on original structure stress analysis, matching the reverse upset model with the point cloud model again, analyzing errors and correcting data, obtaining an original factory building BIM model, and realizing factory building restoration. Through combination of the three-d
