We focus on ground-based sensing techniques, consisting of two stages. In the first stage, I present two new methods using either images or mobile LiDAR data alone for 3D urban modeling. The limitations of using each data alone are discussed, which leads to the sensor fusion research in the next phase. In the second stage, I introduce methodologies to maximize the synergy by fusing images and mobile LIDAR for upsampling range data towards the goal of generating 3D photorealistic urban models. There are fundamental research challenges involved in each stage of this work. In the first stage, I address the ill-posed problem of how much 3D information we can infer from single images. Proposed is a new model-based approach to 3D building reconstruction from single images. This method does not require model-to-image projection and readjustment ...
