Video metrology for documentation of engineering construction

A practical method was developed to calibrate the interior geometry of CCD cameras. The method employs a flat brick wall as a control field. A brick wall is an excellent control field, because it provides a large number of well-defined points at almost any focal setting. When compared with laboratory calibration, which requires a three-dimensional control field, the method of the planar constraint was capable of providing results of comparable accuracy. A RMS error of better than 0.2 pixels in the image residuals was achieved consistently for various focal settings. Using about 50 stereo image points, the interior geometry of a CCD camera was effectively modeled. Increasing the number of image points could increase the accuracy of the calibration parameters.
