Abstract

Photogrammetry in conventional practice requires the use of fixed focus cameras of high precision and calibrated internal geometry. The largest historical application of photogrammetry is aerial topographic mapping which utilizes near vertical photography at infinity focus in a well ordered scheme of flight path terrain coverage with very little vertical ground relief relative to the planned flight altitude. Serious efforts have been made to apply photogrammetry for non topographic purposes (terrestrial photogrammetry) by utilization of conventional or scaled down cameras and stereo compilation instruments with various hardware and applications schemes, Success has been limited, at best, and the solutions have not been economical enough to warrant broad application. With the advent of digital computors, the evolution of numerical photogrammetry in general and the analytic stereo compiler in particular the technical tools are available for a truly comprehensive universal system. With miniaturization and new mathematical techniques small commercial non-precision cameras can be utilized and the photogrammetric process can be greatly simplified and extended to broader application.
