Abstract
A method, system, and computer readable medium for producing orthoimages of the images of a (typically) high-resolution imager of an urban area, the orthoimages of high buildings being imaged with improved accuracy by increasing constraint conditions on the building edges, such as perpendicularity, collinearity. These constraint conditions are merged into an orthorectification model for orthorectifying the images captured at a predetermined elevation, whether by airborne or spaceborne. Constraint conditions may be formed by the building edge points, such as corners, and may be used with a digital building model. Thus, an aspect of embodiments is that the constraint conditions may be directly formed from the building themselves. The higher the buildings, the more effective the constraint controls.
