METHOD OF CORRECTING ARTILLERY FIRE USING A MULTICOPTER Russian patent published in 2020 - IPC F41G3/00 

FIELD: military equipment.

SUBSTANCE: invention relates to methods of air artillery reconnaissance and can be used for correction of firing of artillery by targets, unobserved from firing positions. To correct artillery fire, a multicopter with an onboard video camera and a ground-based control panel with a computer system are used to determine the scale of the video image taken into account in calculating corrective corrections. At the same time with the help of on-board satellite navigation and angular orientation systems the multicopter is suspended with the video camera in the nadir position at the required height above the target with the specified rectangular planned coordinates. Using a software unit built into the computer system software, based on the multicopter height and angular field of vision of the video camera, calculating the length of the diagonal of the rectangular area of the area fixed by the video camera, dividing length of section diagonal in meters by length of video frame diagonal in pixels, determining the scale of the video image in the area of the target, in real time, combining the first crosshair of the under-camera point with the center of the target image and the second movable cross-hairs with the image center of the sighting rupture on the video image. Automatically read from the video frame the difference in coordinates of the centers in pixels, taking into account the scale of the video image, is converted into corresponding differences in meters, which are used as correction corrections during subsequent rounds with projectiles for damage.

EFFECT: higher accuracy and efficiency of correcting artillery fire when using a multicopter in stabilization conditions as a center of mass of the multicopter in space (above the target at the required height), and angular stabilization around the center of mass.
