Abstract
Various examples are directed to systems, devices, and methods effective to transform an image perspective to compensate for a foreshortening effect resulting from an image taken at an angle. An image capture device may capture an image of a subject. A pitch angle of the image capture device may be determined. A transformed, stretched image may be generated by performing a linear perspective transformation of the image. At least one compression value for a portion of the transformed, stretched image may be determined based at least in part on the pitch angle. A nonlinearly transformed image may be generated based at least in part on the portion and the at least one compression value.
