MATHEMATICAL FORMULATION AND DIGITAL ANALYSIS IN CLOSE-RANGE PHOTOGRAMMETRY
One of the major trends in the development of close-range photogrammetry during the past several years has been the increasing use of electronic computers for both data reduction and analysis. In many areas of applications, the most desirable end product of the photogrammetric mapping process is not a contour map but a list of coordinates which define the spatial position of a finite but large number of discrete points. The set of coordinates represents a digital model of the surface. Digital data can be generated by digitizing existing maps, measuring photo image coordinates (fully-analytical approach), or digitizing a stereo model in a stereoplotting instrument (semi-analytical approach). Analytical methods and computer programs are now available for computing object space coordinates from either photo coordinates or arbitrary model coordinates, for modeling lens and film distortions, for camera calibration, and for the generation of graphics such as contour maps and perspective views. Significant advancements have also been made in the application of analytical techniques in stereoscopic measurement using non-metric cameras and scanning electron microscopes. /Author/
