Abstract
Reverse Engineering (Reverse Engineering, referred to as RE), also known as reverse engineering or reverse engineering is to convert the CAD model of physical digital technology related, geometric model reconstruction, and general manufacturing technology.For the rapid development of today; automotive industry, how to shorten the development cycle to ensure product quality, and how fast, accurate and easy access to car parts has become a key three-dimensional data and models.
This paper presents a reverse engineering for automotive lamp product development process solutions to some of the key technologies with a brief discussion, and explained Ruhejinxing car Chedeng's Fan request processing and error analysis.In the specific implementation process, through the software Geomagic reverse on the original point cloud phase, the original scanned point cloud data processing, and then polygon phase, surface phase, CAD phase of the four stages of further processing to arrive at a car light of the three-dimensional surface model, and eventually analyze the errors.
