Abstract

We propose a method of constructing 3D building facade models using high resolution panoramic images. This system mounts three line scan cameras linked by a rotary encoder on a vehicle. The rotary encoder allows the method to capture each line image at regular intervals independent of vehicle speed. We can construct a 3D facade model by the stereo method. We mounted a prototype system and confirmed that high resolution panoramic images, 4mm/line, could be acquired while the vehicle was running at a speed of about 40km/h. 3D building facade models could be constructed from the high resolution panoramic images.
