In the field of industry, Reverse Engineering was paid more attention than before, and had been widely used. Reverse Engineering was a process of gaining digital model from the prototype. It fitted for the sculpting design of products which were complicated in the shape, and had sever free-from surfaces. The key techniques of reverse engineering include: data acquisition，data processing and model reconstruction. By researching on the techniques of data processing, the general manipulation flow of data processing is explored. In light of the characteristics of the model, it is completed with reverse engineering. The data is collected with SEREIN I optical scanner efficiently and accurately. The data processing of shroud parts of the model is done with SURFACER, which results in an integrated and accurate data convenient for model reconstruction. Taking advantage of the Pro/E , the shroud model reconstruction is conducted. The research indicates that the shroud model reconstruction, completed with reverse engineering, is an effective technique, which can bring about high quality model and efficiency and have great actual and practical value.
