heal.abstract	Terrestrial laser scanning has now become a standard tool for 3D surface modeling. In order to exploit such fully 3D data in texturemapping or for the creation of large-scale ‘true orthos’ suitable software is needed, particularly to allow handling surface self-occlusions and image occlusions, as well as multi-image texture interpolation. The authors have presented such an automatic approach for creating orthoimages and perspective views, based on fully 3D models from laser scanning. All surface points visible in the direction of projection are first identified, and then texture from all images which view each particular surface point is blended. Means for automatically eliminating colour outliers from individual images, especially near image occlusion borders, are also provided. In this contribution, the algorithm is evaluated using image sets with large variations in image scale and unconventional imaging configurations. The presented results indicate that this approach, which involves a cooperation of photogrammetry with laser scanning for the automatic multi-view synthesis of textured projections, performs quite satisfactorily also under demanding circumstances.	en
