ABSTRACT:Airborne LiDAR data and optical imagery are two datasets used for 3D building reconstruction. By study of the complementarities of these two datasets, we proposed a primitive-based 3D building reconstruction method, which can use LiDAR data and optical imagery at the same time. The proposed method comprises following steps: (1) recognize primitives from LiDAR point cloud and roughly measure primitives' parameters as initial values, and (2) select primitives' features on the imagery, and (3) optimize primitives' parameters by the constraints of LiDAR point cloud and imagery, and (4) represent 3D building model by these optimized primitives. Compared with other model-based or CSG-based methods, the proposed method has some advantages. It is simpler, because it only uses the most straightforward features, i.e. planes of LiDAR point cloud and points of optical imagery. And it can tightly integrate LiDAR point cloud and optical imagery, that is to say, all primitives' parameters are optimized with all constraints in one step. Recently, an ISPRS Test Project on Urban Classification and 3D Building Reconstruction was launched, two datasets both with airborne LiDAR data and images are provided. The proposed method was applied to Area 3 of Dataset 1 Vaihingen, in which there are some buildings with plane roofs or gable roofs. The organizer of this test project evaluated the submitted reconstructed 3D model using reference data. The result shows the feasibility of the proposed 3D building reconstruction method.

“…The performance of digital aerial cameras has recently been investigated by several research groups (Jacobsen, 2011), (Haala et al, 2010), (Spreckels et al, 2010), (Höhle, 2009a&b). Besides the camera also the flight parameters (altitude, side lap) and the processing tools influence the accuracy of derived elevations.…”

ABSTRACT:Based on practical experiences with the first generation of digital cameras the impact of four new digital aerial cameras on the DEM generation is estimated. The cameras are evaluated with respect to elevation accuracy, area coverage and image quality. In the derived formulae for the absolute accuracy of elevations a camera factor is applied, which summarizes several features in one number. The produced graphs show the potential of the new cameras regarding the relative and absolute accuracy of automatically derived elevations. For better absolute elevation accuracy the increase of the base/height ratio and of the resolving power of lenses are more important than the reduction of the pixel size. Improvement of the elevation accuracy by means of multi-ray photogrammetry is discussed.

“…Finally, Spreckels et al (2010) reported the results obtained in the project DGPF "Evaluation of Digital Photogrammetric Camera Systems", within the working group "stereoplotting". Multiple cameras were used in this project: Film Camera Zeiss RMK Top 15; large format digital cameras UltraCamX Vexcel Imaging and Intergraph / ZI DMC, and the combination of four medium format cameras Digi-CAM Quattro IGI.…”
