Developers and users of industrial inspection systems can choose from a variety of CCD- cameras with large differences in performance and price. Many industrial inspection tasks require the extraction of metric information and ever more frequently of accurate 3D metric information. The performance of CCD-cameras for metric inspection tasks is influenced by a large number of factors such as illumination, sensor characteristics, signal transmission and frame grabbing, calibration techniques, and algorithms. Recent advances in characterization and calibration of CCD-cameras are presented. Measurement accuracies exceeding 1/50th of the pixel spacing were attained with off-the-shelf equipment in controlled laboratory tests. Selection criteria of cameras as a factor of resolution and accuracy requirements are discussed.
