Abstract
We propose a new expression of space-time image which is called "Temporal Height Image (THI)". Assigning a gray value which is in proportion as height to all objects in the space-time volume, we can get THI by looking at the space-time volume above. THI is supposed to be used at urban area mainly. The THI has similar concept as EPI (Epipolar Plane Image), whereas, EPI can't extract edge of object stably. Here, THI can overcome the shortage of EPI by using height of buildings effectively. In this paper, we constructed THIs from actual urban image and 3D-city model, and then aligned these two THIs by DP-matching to verify the effectivity of THI. Then, using the matching result, we tried taking texture mapping onto building models.
