The paper reviews the problems involved in the calibration of photog- rammetric solid-state camera stations and especially describes a method for the continuous online calibration of such a station. In this proce- dure the orientations of the CCD cameras of the station are continuous- ly checked under working conditions by utilizing image matching techni- ques and calibrated reference coordinates. The system is installed in a pilot system working in a car factory. Both simulation and practical results on the performance capabilities are given.
