Geometric and Radiometric Evaluation of the Potential of a High Resolution Cmos -camera

The progress of digital imaging systems has created manifold opportunities and new applications to close range photogrammetry. The classical techniques have found significant changes and this seems to be an ongoing process which is heavily influenced by new technologies showing up on the sensor market. CMOS (Complimentary Metal Oxide Semiconductor) sensors are on of the challenges to CCD sensors as they are providing a similar performance at a cheaper price level. One of the demands is to investigate the radiometric and geometric characteristics of the imaging sensor. This includes considering other factors involved in image acquisition with CMOS sensors and requires a detailed analysis on the factors and its effects for the overall performance of CMOS cameras. This paper analyses the radiometric and geometric performance of the Canon EOS-1Ds, a high resolution CMOS camera. Presented are issues of restoration and geometric correction as well as an experimental investigation using different Canon EOS-1Ds images. Visual inspection and quantitative analysis of the obtained results demonstrate the high productive capability of the Canon EOS-1Ds camera. *Corresponding author.
