摘要: Knowledge about the imaging geometry and acquisition parameters provides useful geometric constraints for analysis extraction of man-made features in aerial imagery, particularly oblique views. We discuss identification horizontal vertical lines scene, using image orientation information vanishing point calculations, calculation their dimensions. The attributions are used to constrain set possible building hypotheses, extracted at corners estimate structure height permit generation three-dimensional models from monocular Results these techniques presented nadir imagery evaluated against manually generated 3D ground truth models. >
