3D building facade model reconstruction using parallel images acquired by line scan cameras

This paper proposes a stereo method robust against occlusions that can reconstruct 3D building facades from images captured from a vehicle. When using ground-based views of facades, the occlusion problem caused by roadside trees and telegraph poles in urban areas is the one of the most difficult barriers. In this study, we show the stereo matching based on parallel images minimize the occlusion effect. To acquire the parallel images, we use two line scan cameras linked a rotary encoder mounted on a vehicle. Experimental results using outdoor scenes confirm the effectiveness of this method.
