Image Perspective Transformationsâ€â€?Urban Scenes [PDF]

open access: possibleOptical Engineering, 1981
This paper discusses a technique for converting digitized oblique low-altitude aerial photography to gray level imagery as seen from other viewing perspectives. The technique makes use of one- and two-camera perspective transformations. Inputs to these transformations are camera model information and a stick figure representation of the scene.
