Three Dimensional Information Extraction of Buildings Using ShadowFrom A Single Image

Abstract

The three dimensional information of buildings is an important issue in urban
monitoring, planning, management and various economic activities, and as a result
of the tremendous development in the devices and remote sensing sensors, there is a
need to obtain information about geographical locations with less cost, therefore the
goal of this research is to extract the three dimensional information of buildings
using shadow analysis appears in the 2D image and solving for the slope of view for
this shadow without the need for additional data (another overlapping image or
digital elevation model).
