【Abstract】 Aim\ To summarize the technology of 3D reconstruction based on layer data. Methods\ The technology is expatiated and the advantage and disadvantage of each technologies are analysed. Results\ Almost all technology are used in medical imaging, but the theory for industrial application is not yet ripe. Conclusion\ Transplanting the reconstruction technology in medical imaging to the 3D modeling of industrial product, the technology adapted to industry would be developed.更多还原
