The state-of -the-art in sensor techniques for close-range photogrammetry is characterized by two major trends. In the field of photographic sensors reseau cameras are gradually superseding conventional metric systems and leading to camera systems of very high accuracy. Fully digital imaging systems are also advancing, and particular use is made of CCD cameras with standard video output. Higher resolutions can currently be only achieved if the object is recorded sequentially by a moving CCD sensor in the image space. Additional illumination devices and object targeting have to be involved in the photogrammetric recording process. Image recording systems are only one component of a total system. In order to judge the efficiency of the system the complete object recording and data processing procedure must be taken into account.
