3D building models are helpful for interpretation of the image contents. Registering them with the images a matching of image features and corresponding structures in the 3D model is required. In this work a method to register a building model and extracted features detected in IR image sequences taken by helicopter or UAVs is presented. Polygons of the building model are projected to the images, using coarse orientation parameters obtained by GPS/INS. By the point-to-point matching of projected polygons and features extracted from the image the values of the projection matrix are improved. Two different point types, i.e. Förstner points and intersection points, are extracted in infrared (IR) images and used for matching. For experiments a sample data set from a dense urban area is used and presented results are evaluated.     «
