Photogrammetric manipulation of imagery has been, for the major part, a point-based operation. The utilization of points remains to be convenient since few manually digitized points can be accurately obtained to carry out various photogrammetric orientation procedures (e.g., relative and absolute orientation as well as photogrammetric triangulation). On the other hand, the constant evolution of...

Considerable research attention has been given to close-range videometric systems for vision-based, three-dimensional object measurement over recent years. These systems have to demonstrate high speed, high accuracy capability and high flexibility to compete as a three-dimensional coordinate measurement tool. Especially in industries where instant feedback is required, such as production line o...

The modeling of three-dimensional objects is a current topic in digital photogrammetric research. The modeling of buildings in digital imagery or digital surface models involving automation processes has reached a level where it can compete with classical photogrammetric stereo measurements. There are many different ways on how to integrate automation. We describe our system and its automated f...

The massive introduction of modern digital photogrammetric workstations into routine mapping activities has obviously changed the tools and context of photogrammetric practice.
