摘要：At the moment, fundamental changes in sensors, platforms and applications are taking place. The paper describes present development activities and future application aspects of data processing and auto mation in the workflow of the Digital Modular Camera DMC from Z/I Imaging. For many decades, Aerial Cameras developed and manufactured by Carl Zeiss Photogrammetry Division have been used successfully all over the world as high performance systems for aerial photography. These activities are now com- pletely taken over b y Z/I IMAGING, an Intergraph - Carl Zeiss joint venture. At present, two different approaches of digital camera systems, one based on linear sensors and the other based on ma- trix sensors, are under development. The key issue of the whole photogrammetric system process is the geometric im- age accuracy, which is mostly defined by the camera sensor itself. In order to fulfill the high requirements of mapping applications, ZI Imaging has decided to base the new DMC on a CCD-matrix sensor. High ground coverage of this new approach is achieved b y a combination of several camera modules, where each CCD sensor is mou nted to its own lens. First flight tests with a demonstrator have already shown high resolution and accuracy in the centimeter range at low flying altitudes, due to the electronic FMC function of the DMC. This paper also gives a complete overview of the needed data processing steps and the integration of DMC imagery into existing photogrammetric workstations. The paper discusses in detail the fully automatic data post-processing steps, to apply sensor normalization for each CCD array, the functional approach of setting up panchromatic image mosaics and finally the generation procedure for color composites. Additional focus is drawn to several image products optionally deliverable directly from the post-processing procedure
