Camera and auxiliary sensor calibration for a multispectral panoramic vision system with a distributed aperture

Abstract

Abstract The constructions of test objects for calibrating cameras of the visible and infrared ranges that make up the panoramic survey optoelectronic system, as well as calibration algorithms for auxiliary inertial microelectromechanical sensors for determining the angular position are considered. The results of image forming from a virtual camera that realizes the transfer of the centre of the generated panoramic video image to the observer’s placement point are presented. As part of the field experiment with cameras of the visible and long-wave infrared ranges, it was shown that calibration of the sensors of the panoramic system with a distributed aperture at a known distance to the objects of observation results in an error of combining multi-spectral images of not more than 3′.
