Executive Summary

The camera parameters are changed due to temperature variations, which directly influence calibrated cameras accuracy. Robustness of calibration methods were measured and their accuracy was tested. An error ratio due to camera parameters change with respect to total error originated during calibration process was determined. It pointed out that influence of temperature variations decrease by increasing distance of observed objects from cameras the building site images should be captured from multiple cameras, with fixed positions and orientations. Joining multiple cameras views is possible, if multiple camera system setup is calibrated. Camera calibration can be performed by various methods like eight-point algorithm,
