Abstract
The reverse-engineering technology is based on the new design ideas and methods. This technique led to the product model for the accuracy of expression and reconstruction.For further analysis, optimization and manufacture of products establishes a unified object ,product design and development of rapid and complex aspects of surface machining of great significance.The reverse-engineering applying to the automobile panal product may reduce the development cycle greatly,and promote the quality assurance. This paper presents a reverse engineering process solutions for automotive product development, to make some brief discussion of the key technologies, then described how to reconstruct the car by engineering processing and make a error analysis. In the specific implementation process, firstly by imageware software in reverse engineering on point cloud data of cars, for point cloud data preprocessing, point cloud block, the feature extraction, construction and other operations section curve get to the surface reconstruction information, then input to the UG for reconstruction surface, finally obtains the automobile three dimensional surface model the completion of the reverse design.
