Shooting aiming track detection method based on live ammunition bullet holes in target and gun gesture detection

Abstract

Provided is a shooting aiming track detection method based on live ammunition bullet holes in a target and gun gesture detection. The shooting aiming track detection method based on the live ammunition bullet holes in the target and gun gesture detection comprises the following steps that (1) a gesture track on the target is obtained through a six-dimensional gesture sensor additionally installed on a gun; (2) image acquisition is carried out on the target surface through a camera, and the relative impact point position of the recent bullet on the target surface is determined in real time through image processing and image recognition after live ammunition percussion is accomplished according to images of the target surface and pulse trigger signals generated by live ammunition percussion; (3) the data deviation between a synchronous coordinate point and the relative impact point position is calculated to obtain the drift distance of the gesture track; (4) subtraction between discrete values of points on the gesture track on the target and the drift distance is carried out, a gesture track sequence can be corrected to form an aiming track penetrating through the impact point, and a shooting aiming track can be obtained. According to the shooting aiming track detection method based on the live ammunition bullet holes in the target and gun gesture detection, detection accuracy is effectively improved.

Description

technical field

[0001] The invention relates to a live ammunition shooting and aiming training technology, in particular to a method for detecting a shooting and aiming track. Background technique

[0002] At present, the method of cursor tracking description is used in shooting aiming training, that is, the laser beam emitting device on the gun is used to generate a laser pointing mark, and the light point mark formed by the cursor on the target surface is used to record the position of the cursor on the target surface by the camera. The trajectory on the target surface, that is, the record of the aiming and pointing trajectory. This method of detection and recording is restricted by the frame rate of the camera, that is, 25-30 frames per second, which is equivalent to a description accuracy of 25-30 points per second for the aiming and pointing trajectory. Hundreds of dots per second, in order to more finely describe the fine trajectory changes of the forced aiming point ...

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] refer to figure 1 and figure 2 , a shooting aiming track detection method based on live ammunition bullet holes and gun attitude detection on the target, comprising the following steps:

[0020] (1) Use the six-dimensional attitude sensor 1 composed of a three-dimensional acceleration sensor and a digital gyroscope installed on the gun to form a real-time detection of the gun's aiming attitude. The instantaneous pointing of the gun muzzle is described through the attitude data of the gun, and then the aiming trajectory of the sequence on the target surface is calculated through the data sequence of these instantaneous pointing positions. We call this the on-target pose trajectory. The discrete description accuracy of this trajectory is restricted by the data sampling rate of the above-mentioned six-dimensional attitude sensor, which can reach up to 800 point...
