Paper Abstract

Nowadays high-resolution cameras are used more frequently for solving measuring problems. Applications range from 2D- to complex photogrammetric 3D-measurements. Using a digital image recording system for measuring purposes however requires an exact knowledge about the reachable accuracy, taking into account the different modules like lenses, sensor, analog- to-digital converter and components, which in most cases are necessary to get a higher resolution (for example shifting devices or reseau plates). At the IPB a photogrammetric procedure was developed, which allows a fast determination of the geometrical efficiency and a calibration of any digital image recording device. A testfield with points, which 3D- coordinates must be known only approximately, is recorded in different images, which defines a geometrically stable photogrammetric network. All measured image points are used to compute a bundle adjustment. The results of the computation show the overall geometric accuracy of the system and the effect of different system parameters (for example lens distortion and pixel affinity). The paper gives a detailed description of the method and shows results of the evaluation and calibration of different high resolution camera systems.
