Abstract
Abstract. Multimedia camera calibration is a challenging, yet increasingly important task. Due to the lack of software with appropriate models, implicit calibrations with standard single-media models are often performed, despite the well-known fact that distance-dependent errors arise from neglecting the specific multimedia influences. This becomes particularly relevant when test field calibrations are employed. We present a thorough simulation approach that shows the influence of distance-dependent errors when performing implicit calibration. Results show major accuracy decreases for performing measurements far from the calibration distance while closer distances may compensate the errors quite well. Furthermore, we investigate on the behavior of different test field geometries and angles between interface and optical axis which particularly affects the achievable accuracy.
