FIELD: radio engineering, communication.SUBSTANCE: coordinates of fault locations are determined based on coordinates of points of thermal images with high temperature. In a differential mode of a satellite radio navigation system, directional cosines of vectors from points of the centre and corners of the thermal image to the centre of the camera lens of the thermal imager are calculated in a coordinate system linked with an aircraft based on values of the viewing angles of the camera of the thermal imager; directional cosines of these vectors are determined in a topocentric coordinate system based on the measured spatial orientation angles of the aircraft and a rotation matrix, expressed through Euler angles; distance from the points of the thermal image to the centre of the camera lens of the thermal imager is determined based on information on the height of the diagnosed object above the earth, the altitude of the aircraft, measured by an altimeter.EFFECT: broader functional capabilities.4 dwg |
