Summary:This paper presents a new non-electrically powered calibration rig designed for geometric calibration and spatial alignment of cameras operating in the VIS-NIR, SWIR and LWIR wavebands. Quantitative tests and experiments have been performed to identify materials, paint, varnish and configuration offering optimal properties in all wavebands. The performances obtained with this new rig were evaluated in terms of image contrast and corner detection ability. We demonstrate that the design is suitable to be used not only indoor, but also in outdoor environment with varying illumination (night, sunny and overcast day) and weather conditions (wind, cold temperature).
