Training ground multi-target-position automatic target-scoring method and system based on high-definition camera

Abstract

The invention discloses a training ground multi-target-position automatic target-scoring method and system based on a high-definition camera. The method comprises the steps that digital mark numbers are arranged on target surfaces of a plurality of target positions placed in parallel target surface directions; the high-definition camera is adopted to shoot panoramic images of all target positionsin the direction perpendicular to the target surfaces; target surface images and the digital mark numbers of all target positions are identified on the shot panoramic images; a pressure sensor is mounted on each target position, current target surface images of the corresponding target positions are stored according to pressure sensing information generated by shooting, the radius ranges of the target ring numbers are inquired according to the distances between the identified shot point coordinates and the target center coordinates, and shooting results are obtained; whole field shooting results and shot point calculation images are output through liquid crystal displays; and individual firing scores are singly played to all shooters through sound playback devices. The positions where bullets in the target surfaces enter the target surfaces are obtained, the high-precision, high-resolution, high-speed automatic target-scoring system is achieved, and the system is as shown in an abstract drawing.

Description

technical field [0001] The invention relates to a target reporting device for firearm shooting, in particular to a target reporting method and system based on a high-definition camera, which can perform automatic target reporting on multiple target positions at the same time. Background technique [0002] At present, in shooting training and competitions, the automatic target reporting technologies used mainly include: automatic target reporting based on acoustics, automatic target reporting based on video images, laser sensor target reporting, and multi-mode fusion target reporting. The Chinese patent "An automatic correction method and target reporting system for a target reporting system" (Domestic Patent Publication No. CN103591852A) comprehensively uses the ultrasonic signal of the impact point and the image coordinate analysis results to locate the impact point of live ammunition shooting. Large environmental impact, poor reliability, low detection accuracy and other p...

Problems solved by technology

The Chinese patent "An automatic correction method and target reporting system for a target reporting system" (Domestic Patent Publication No. CN103591852A) comprehensively uses the ultrasonic signal of the impact point and the image coordinate analysis results to locate the impact point of live ammunition shooting. Large environmental impact, poor reliability, low detection accuracy and other problems; Chinese patent "a camera-based target reporting method and system"

[0003] (domestic patent publication number CN101694363A), designed an automatic target reporting system based on multiple cameras to determine the coordinates of the impact point, each target position needs to install at least two cameras, the cost is high, and it needs to be based on the size of the target paper and the installation position of the cameras The mapping relationship is calculated in advance, and the maintenance is complicated; the Chinese patent "A Laser Target Automatic Reporting Device" (Domestic Patent Publication No. CN206037842U) has designed a high-sensitivity laser emitting and receiving device, which is generated by the electrical parameters of the laser receiving device. For the automatic target reporting system that changes and determines the coordinates, a large number of light sources need to be aligned with the corresponding photosensitive tube receivers one by one for irradiation, the debugging workload is heavy, and maintenance is difficult. Enough, the accuracy of detecting the position of the bullet is not high enough
