Abstract

This thesis shows an approach to remove discontinuities in the color appearance from range images. To produce a point cloud of an object it is necessary to scan it with an 3D Scanner from several positions that the whole object is covered in the point cloud. After the scanning the different scans have to be merged which causes the problems in the color appearance. These discontinuities come e.g. from different light situations and the distance between scanned point and scanner.

This thesis shows an possible solution for this problem. The solution covers an image processing part, here are just the pictures which are made during the scanning process revised. The second part is about the processing of the already colored point cloud and re-color points according to different factors like the distance from the scanner, occlusion and so on.
