Geometrical calibration of multispectral calibration
In this paper, we introduce a novel calibration pattern board for visible and thermal camera calibration. Our pattern board is easy to make, handy to move and efficient to heat. Also, it preserves a uniform thermal radiance for a long time. Proposed method can be employed in single- and multi- spectral camera system, and also used in the splitter or stereo camera system. As a result, our method shows a good performance comparing with previous works, and we also shows that the calibrated system is enough to use in ADAS systems.
