Being pioneering, integrated and comparatively practical, reverse engineering has become an indispensable technique in product exploitation. Reverse engineering can enhance the precision of design, produce high quality model and shorten the cycle of design and manufacture. As a result, it holds out broad prospects for application and is thought highly of in both industrial and academic circles in many countries. The key techniques of reverse engineering are researched and applied to shroud model reconst- ruction of toy car in this thesis.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 shroud parts of motorcycles, the shroud model reconstruction of toy car is completed with reverse engineering. The data is collected with ATOS I optical scanner efficiently and accurately. The data processing of shroud parts of toy car is done with CATIA, which results in an integrated and accurate data convenient for model reconstruction. Taking advantage of the combination of Pro/E and CATIA, the shroud model reconstruction of toy car is conducted.The research indicates that the shroud model reconstruction of toy car, completed with reverse engineering, is an effective technique, which can bring about high quality model and efficiency and have great actual and practical value.Key words: Reverse Engineering; CATIA; Pro/E;Signature of Supervisor:Yu Fei
