A camera target reporting device and target reporting method

Abstract

The invention discloses a camera target reporting device and a target reporting method. The camera target reporting device is composed of a target body, a main light source, a camera and a target reporting processing module. The target body is a cavity structure, and the inner wall of the target body cavity has reflective properties; the main light source is set inside the cavity of the target body, and the main light source continuously emits light of a single wavelength; multiple auxiliary light sources are also set on the target surface of the target body to assist The wavelength of the light emitted by the light source is the same as that of the main light source; the camera is aimed at the target surface, and a filter is set on the lens of the camera. The filter can only pass through the light of a single wavelength emitted by the main light source and the auxiliary light source, and filter out other The light of the wavelength; the video data captured by the camera is sent to the target reporting processing module. During live ammunition shooting, when the bullet passes through the target body, the light emitted by the main light source is reflected by the inner wall of the target body cavity and then penetrates through the projectile hole, and the camera sends the captured image of the projectile hole light spot to the target report processing module. The target reporting processing module can accurately calculate the position where the bullet hits the target surface according to the relative position of the light spot of the projectile hole and the light spots of multiple auxiliary light sources. The camera target reporting device and target reporting method of the present invention use a plurality of auxiliary light sources to assist in measuring the position where the bullet hits the target surface, which can effectively reduce the difficulty of image recognition, improve the accuracy of target reporting, and overcome the impact of ambient light on image recognition and accuracy. Impact.

Description

technical field [0001] The invention relates to the field of military training equipment, in particular to a camera target reporting device for live ammunition shooting. The invention also proposes a method for using the camera target reporting device for target reporting. Background technique [0002] In the field of live ammunition target reporting technology, there have been many patents and papers on target reporting using image recognition technology, but at present these methods and technologies have many defects, resulting in that they can only be used in specific occasions such as indoors, and the target reporting accuracy is not good. High, prone to misstatements and omissions. [0003] The main flaws and deficiencies are: [0004] (1) The false alarm rate is high. The commonly used image target reporting technology performs target reporting by identifying and comparing existing bullet holes and newly added bullet holes on the target surface. If a newly fired bull...
