Image-based Approach to Generation of Offset Curves from Point Cloud*
In this paper, an image-based approach for the generation of offset curves from point cloud is presented. The offset curves/surfaces can be applied to refine the prototype produced by using the rapid prototype method to remedy the potential low precise problem. To reduce the computational complexion, in the approach, the cloud data is segmented into a number of layers by slicing the point cloud along a user-specified direction, i.e. machining direction. The data points in each layer are projected onto a plane that is perpendicular to the machining direction. Furthermore, the data points on the place are transformed into grey-level values on a two dimensional space based on the distance away from the plane. After that, the offset curves can be directly computed by using the linear diffusionbased segmentation method. Although a perfect result hasnt be achieved, the numerical experimental result shows that the proposed approach is more prospective than the existing ones. One of most advantages is more efficiency and with much less computational cost.
