Abstract: With the help of CCD images, realization of high-precision positioning and measurement has become the basic standard for machine vision and real-time photogrammetry systems. However, deformation and other degradation occurring during transmission are major limiting factors of the precision attainable with most current CCD cameras and framegrabbers. So precise radiometric and geometric transmission of images from CCD sensor to memory is a fundamental aspect of CCD camera calibration. A geometric calibration system that uses some image processing algorithms of the CCD camera based on the SOKKIA analytical plotter is discussed. Reliability is also discussed. The experimental results for the calibration of the CCD array are taken as an important quality index for CCD evaluation. !14
