In recent years, considerable developments have occurred in the field of digital photogrammetry. These have been due mainly to increases in computing power, the refinement of feature- and area-based image matching algorithms and the reduction in cost of equipment capable of producing near real-time images in digital format. Despite the progress, a major limitation to the widespread application of digital photogrammetry is the resolution of the digital images being used. Much time and effort has been expended trying to improve resolution through hardware solutions consisting of imaging sensors with increased numbers of pixels. An alternative solution is offered in this paper. An algorithm which uses a combination of photogrammetric techniques and a rigorous mathematical solution to enhance the resolution of digital images is described.
