Abstract:

This paper reports an automated multiview threedimensional data registration scheme for fullyautomated threedimensional scanning system. We used singleaxis precise turntable to help to get multiview point cloud and to integrate them together. First, we used a quick and easy way to get the three dimensional information of the turntable’s central axis, and then integrated the multiview point cloud to get model body via the axis. After that we completed the initial registration of point cloud with the help of minimum bounding box. At last we completed the precise registration using improved ICP algorithm. In this paper, we provided several suggestions for the imprecise registration problem between the top and the bottom of the model. At the end of this paper, experiment results are presented, and experiments show that the scheme has good maneuverability and high accuracy.

Key words: 3D integration, ICP algorithm, minimum bounding box
