Sažetak
This paper examines the influence of radial and tangential lens distortion of non-metric digital cameras on the accuracy of the photogrammetric survey, primarily using the method of photo-triangulation with self-calibration. 2D-template with the marks measured using image correlation is being used as a test field to determine the distortion. The results indicate decisive influence of radial and tangential distortion on the results of photogrammetric measurements and also of self-calibration. Therefore, we propose an independent predetermination of the effects of distortion and its elimination before self-calibration. The results were confirmed by independent equalization of photo-triangulation with newly introduced parameters.
