Repairing Incomplete Measured Data with Haptic Interaction

Measured data of a product can be incomplete because of the inaccessibility or invisibility of some portions of the product surface for measure tools in reverse engineering, which could makes it difficult for reverse engineering systems to create the CAD model from those measured data. In this paper, a novel incomplete data repair method based on haptic interaction is presented. Starting from the import of a dataset digitized from a physical object, various haptic sculpting tools are explored to repair the incomplete measured data, and the shape and size of these tools may be changed dynamically to satisfy specific situations, which forms a flexible and intuitive sculpting toolbox used to clean and repair the measured data. A high-quality STL file can be obtained from the system which is ideal for rapid prototyping. Case study is also given to demonstrate the feasibility of this new method, and finally a future direction of integration repairing measured data with designing innovative new object through haptic interaction in reverse engineering is proposed.
