Influence of temperature variations on calibrated cameras
Peter Podbreznik, Božidar Potočnik, 2008, izvirni znanstveni članek

Opis: 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.

Analytical camera model supplemented with influence of temperature variations
Peter Podbreznik, Božidar Potočnik, 2008, izvirni znanstveni članek

Opis: A camera in the building site is exposed to different weather conditions. Differences between images of the same scene captured with the same camera arise also due to temperature variations. The influence of temperature changes on camera parameters were modelled and integrated into existing analytical camera model. Modified camera model enables quantitatively assessing the influence of temperature variations.
