TRACKING MOVING-OBJECTS WITH DIGITAL PHOTOGRAMMETRIC SYSTEMS

Fully digital photogrammetric close range systems allow for on line or even real time processing of data. This gives access to a great number of new applications, especially in those cases where a moving object has to be dynamically recorded or a moving sensor has to be positioned and oriented in three dimensional space, as is the case in robotics. This article gives a brief survey of the problems and potential of these new systems and techniques. Aspects of fast data acquisition and processing are addressed and a concise description of the DIPS II digital station is provided. The accuracy of digital systems is reviewed and two significant new algorithmic developments are referenced. Finally, three characteristic projects demonstrate the potential and performance of digital close range photogrammetry.
