Problems solved by technology

This method adopts a unified threshold in the bullet hole recognition method, and does not consider the influence of ambient light and uneven illumination, nor does it take into account the distortion of the image, so the number of rings will also have errors

Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings.

[0065] The live ammunition shooting system is a military and police live ammunition shooting training system under the full control of the computer. It consists of a target projector (TPU) and a CCD camera (CCD). Both the target computer (TC) and the central computer (CC) can be ordinary personal computers, the target screen (TS) is double-layer paper fixed on the bullet hole self-covering control unit (ARU), and the chest ring target projector (TPU) It is used to project on the target screen (TS) to generate a target image, and the CCD camera (CCD) captures the image on the target screen (TS) for program analysis on the target computer (TC), the central computer (CC) and multiple target The bit computer (TC) is interconnected with the network access device through TCP / IP.

Abstract

The invention provides a kind service practice firing system and the method for identifying the bullet hole of slow fire, the system includes: a centre computer (TC), a target position computer (TC), a bullet hole automatic overlaying control device (ARU), a chest ring target projecting apparatus (TPU), a target screen (TS), a CCD camera; the method includes: it intercepts the smaller chest ring target from the target position diagram; when carries on bullet hole identification, it uses area integrating, reduces the computing area, uses self-adaptive fuzzy decision function to identify the bullet holes in the small area around the bullet hole; the calculating rings quantity uses one calculation and two times of check.

Description

technical field [0001] The invention relates to the field of military police and sports training automation, in particular to a live ammunition shooting system and a method for identifying slow-fire bullet holes, which adopts a computer image processing and pattern recognition training guidance system. Background technique [0002] Related technologies in this field have been studied at home and abroad. Most of the shooting training systems that exist at present are separate instruments, or stand-alone systems with a PC as the core, which only allow a certain shooting result of an individual to be identified. In order to support multi-person and multi-group training at the same time, some systems have proposed a network-based method, but those solutions have the disadvantages of high system cost, fixed number of target computers, no fault-tolerant mechanism, or weak statistical function due to the need for special instrument support. , and there are still many places to be ...
