This paper discusses a technique for converting digitized oblique aerial photography to gray level imagery as seen from other viewing perspectives. The one- and two-camera perspective transformations are derived and applied. Inputs to these transformations are camera model information and a stick figure representation of the scene. The required camera model information is extracted from the imagery in conjunction with limited map data. Three-dimensional stick figure models are constructed interactively using the camera model and the digitized photograph. Using the stick figure information, pixel-by-pixel gray level transformations and hidden surface corrections are performed to produce the new perspective views. The resulting images maintain the noise and resolution qualities of the original digitized imagery.
