Method for judging targeting of simulated shooting for tank element training based on image analysis

The invention discloses a method for judging the targeting of simulated shooting for tank element training based on image analysis, which comprises the following steps of: installing a video camera facing forwards on one's own gun barrel, and acquiring images by using the video camera, wherein the optical axis of the video camera coincides with or is parallel to the axis of the gun barrel or the axis of a sighting telescope; installing the video camera on a dual-axis tilt sensor in parallel, and providing the horizontal angle and the pitch angle of the video camera by the tilt sensor; installing invisible infrared light sources with different flicker frequencies and beats on different targets to mark the numbers and the indicating positions of the targets; starting to collect images when one's own gunner sights the target, and stopping collection until the gunner presses a shooting button and images that a cannonball reaches the target; and transmitting the collected images to a processing unit, detecting the existence of the light source in each image and the position of the light source by the processing unit, obtaining the flicker frequencies and the beats of the light sources in the visual field through multiple continuous images so as to obtain the identity of a tank, and judging whether the target is hit and the hitting position.

Digital aerogun target-correcting method applied to airplane general assembly

The invention discloses a digital aerogun target-correcting method applied to airplane general assembly. The method comprises the following steps of: 1) leveling an airplane and unifying a measuring coordinate system of a laser tracking instrument with an assembling coordinate system of an airplane general assembly station; 2) measuring 2# and 12# points by using the laser tracking instrument andautomatically building a symmetrical axis of the airplane by using a computer; 3) starting a measuring program and measuring four target points on an aerogun target-correcting tool in a manually or automatically measuring mode; 4) calculating and graphically displaying a distance between a midpoint of a connecting line of left and right gun barrel aiming points and a central point of a target plate, if the distance meets the requirement, finishing the aerogun target-correcting process, and if the distance does not meet the requirement, turning to a step 5); and 5) according to the prompt of acomputer, manually regulating the aerogun and repeating the steps 3) and 4) after regulating until the distance meets the aerogun target-correcting requirement. The method has the advantages of effectively improving target-correcting precision, greatly improving target-correcting efficiency, obviously reducing the dependence of the target-correcting operation on the work on-site space size and improving the automation and integration levels of the airplane general assembly.

Gun target

ActiveCN111854537AFolding stableSolve the technical problems of unstable support and inconvenient transportation and storageTargetsTarget surfaceClassical mechanics
The invention provides a gun target, and belongs to the technical field of shooting training equipment. The gun target comprises a target surface, a turnover frame, a supporting frame, supporting legsand connecting rods; the turnover frame is used for supporting the target surface, the position of the target surface on the turnover frame is adjustable, and the target surface is telescopically sleeved with the turnover frame through an inserting telescopic mechanism; the supporting frame is used for supporting the turnover frame, the turnover frame is hinged to the supporting frame and can rotate around a hinge point, and first storage grooves are formed in the lower portion of the supporting frame; the supporting legs are arranged on the front face and the back face of the supporting frame and used for supporting the supporting frame, and second storage grooves are formed in the supporting legs; and one ends of the connecting rods are hinged to the lower portion of the supporting frame, the other ends of the connecting rods are hinged to the middle parts of the supporting legs, and the connecting rods and the supporting legs can be stored in the first storage grooves. The gun target has the technical effects that the target surface and the turnover frame are telescopic and foldable, so that the occupied space is small; the height and the position of the target surface can be adjusted according to scenes when the gun target is used, so that the target surface is stably supported; and the gun target is convenient to store, fold, carry and transport.
