N1 - Funding Information: The presented work has been done within in the scope of the junior research group “Automatic methods for the fusion, reduction and consistent combination of complex, heterogeneous geoinfor-mation”. The project is funded by the VolkswagenStiftung. Funding Information: Our registration method proposed in this paper is based on extracted planar patches from 3D terrestrial laser scanning data. The matching of correspondent patches is supported by geometrical features derived from the data. We also work with a hybrid sensor system and also take advantage of recorded image data. In the next section hybrid data acquisition sensors and the combination of 3D point data and 2D image data are described. Then the registration technique using geometric constraints and finally the integration of the image data into the registration process is discussed. We conclude this paper with a summary and outlook.

N2 - The fully automatic registration of terrestrial scan data is still a major topic for many research groups. Existent methods used in commercial software often use artificial markers which are placed in the scene and measured from each scan position. This is a reliable method to get the transformation parameters, but it is not very efficient. These manual or semi-automated registration techniques should be substituted by new methods in order to make terrestrial laser scanning also profitable for larger projects. In this paper we present a registration method based on the extraction of planar patches from 3D laser scanning data. A search technique is used to find corresponding patches in two overlapping scan positions. Since laser scanning instruments are nowadays often equipped with an additional image sensor, we also use the image information to improve the registration process. Assuming that the calibration parameters of a hybrid sensor system are known, the extracted planar patches can be textured automatically. The correlation between corresponding textured patches can be calculated and the registration method is improved by shifting the patches until they fit best.
