Abstract
In this paper two cameras have been used to determined the interior orientation parameters (IOP) for each camera. To carry out the calibration, Photomodeler Scanner software was used. The lab calibration process was completely automatic using a calibration grid. The focal length was fixed at narrowest and widest angle and the network includes a total of twelve images with ± 90º roll angles. Each zoom was calibrated for five times. After the software processing, the camera calibration parameter values were obtained.The paper presents the results and the accuracy of this calibration method, Furthermore the overall RMSs obtained from the calibration for both cameras are in micron but calibration cannot be considered as constant or fixed for non-metric cameras, because such cameras have different (IOP) for each capture.
