Combining Intensity and Range Data for 3D Architectiral Modelling
A major problem in 3D Reconstruction based on laser range data is the poor spatial resolution of laser measurements. This creates some jitter in spatial discontinuities. This paper presents techniques combining video intensity and range data to improve 3D models of architectural environments rich in geometric features. The main novelty is the use of the intensity information not only for texturing the final 3D model but also to improve the segmentation of the range data. The technique registers video and range, i.e., the camera parameters are computed in order to get both data in the same reference frame. Edge extraction techniques are then applied to select corresponding edges and a line-straightening algorithm is used to correct the 3D model. Results are presented for both indoor and outdoor environments.
