| Abstract: | Aiming to adapting to today's production need for a versatile products on small volume. This thesis discusses how to use 3 D measurement technology, which employs linear laser and dual CCD image-catching technology, to build a reverse engineering measurement system. The key element in reverse engineering is the application of new measurement technology to digitizing a sample's 3 D appearance to create 3 D CAD data.Reverse engineering measurement system can efficiently digitize a 3 D,and,by utilizing an edge detector,data filter,and curve and surface restructuring technology create a 3 D surface model,shortening products' design time. |
