Abstract

A 3-D model reconstruction method based on modifying measured points is proposed in this article. In this study, an automatic feature-section generating system for constructing a 3-D product model is built based on reverse engineering concepts. The designer can construct a 3-D model with PU foam artificially. Data points on product surface are then measured using a non-contact 3-D scanning device. Then the point clouds for cross-sections of this product are gotten based on the measured data points. A parametric program for generating cross-sectional curves of a product by regulating the designed parameters is built in this study. With the aid of this program, smooth product models can be obtained by regulating the required parameters. Two different product models can further be used to generate new shapes by using shape-blending techniques. The obtained results can also be taken as the input data of another commercialized CAD system in IGES format to create a 3D product model in rendered form. In this manner, designers can construct a smooth product that fits user's demand in a shorter time.
