Abstract

Knowledge about the imaging geometry and acquisition parameters provides useful geometric constraints for the analysis and extraction of man-made features in aerial imagery, particularly in oblique views. In this paper, we discuss the application of vanishing points for the identification of vertical and horizontal lines, and the use of multiple views for verification of these lines. The vertical and horizontal attributions are used to constrain the set of possible building hypotheses. Preliminary results exploiting these attributions are described.
