Image-Based Vehicle Localization Using a Series of Building Height Information Timeline Height Image and Texuring Building Model.

This paper proposes a novel expression of space-time volume, called Temporal Height Image (THI). Assigning a gray value in proportion to height to all the objects in this space-time volume, the authors can obtain THI by looking at the volume from above. THI is supposed to be applied to urban area mainly. Having the similar concept to Epipolar Plane Image (EPI), but THI can overcome the shortages of EPI (i.e. edges inside the building disrupt result). In this paper, after constructing THIs from actual urban imageand 3D-city model, we align the two THIs by DP-matching. Then we use matching result to make texture mapping onto building model surface.
