Paper Abstract

A system for real-time applications in close-range and industrial photogrammetry is presented. Special attention is given to system design and implementation. The system consists of a variable number of active and passive image sensors controlled by an multi-processor computer environment. The image processing unit incorporates various methods for automated measurement of targets, laser spots and object elements. System calibration is done by rigorous bundle adjustment. Target determination is performed by single-image measurements, while spatial object elements (circles, planes, edges) are processed by multi-image edge-matching techniques. Overall system control is implemented by a flexible programming language. The system can work in two different modes, teach-in and automatic measurement. Both hardware and software components are designed for use in an industrial environment. Particular importance is given to ease-of-use and robust operations. The system will initially be used for quality control applications in the automobile industry.
