【 摘 要 】

Surface reconstruction is the core of reverse engineering. Based on Geomagic Studio software for point-stage processing, polygon stage processing and surface construction, two different surface reconstruction methods, the precise surface reconstruction method and the B-spline surface reconstruction method, are discussed. Reconstruction and error analysis were performed on the same blade model. The analysis shows that the overall reconstruction error of the blade reconstructed model based on the approximate surface reconstruction method is 4.91%, and the overall reconstruction error of the blade reconstructed model based on the B-Spline reconstruction method is 28.83%. Obviously, the exact surface reconstruction is more suitable for the reconstruction of complex surfaces than the B-spline reconstruction method.
