Multi-resolution 3D reconstruction of city statue based on laser scanning and photogrammetric concept

In order to improve the visualization effects of some areas in cyber city, it´s often required to reconstruct 3D model of city statues. In this paper, we present a pipeline to build 3D city statue model of high fidelity that fusing multi-resolution LIDAR data and high-resolution digital images. Firstly, the classic ICP algorithm is used to register multi-resolution LIDAR data. Secondly, the geometric seams between multi-resolution LIDAR data are fused by a progressive fusion strategy. Finally, a virtual camera based on basic Photogrammetry concept is proposed to do the texture mapping. Combining all kinds of automatic and semi-automatic methods, the pipeline works well for 3D reconstruction with multi-resolution laser scanning data and high-resolution digital images.
