Conceptual issues of softcopy photogrammetric workstations

A conceptual approach to digital photogrammetry is presented. Automation of photogrammetric processes on digital photogrammetric workstations is considered with particular attention given to the automatic orientation and the surface reconstruction module. It is suggested that major progress toward autonomous softcopy workstations depends more on advances on the conceptual level rather than on refinement of system components such as hardware and algorithms.
