Abstract
The present invention proposes a kind of Portable Automatic scoring round target device based on telephoto lens, and the device is used in small arms ball firing training or examination, is easy to point of impact on shooter's Real Time Observation target plate.The device is made up of following part：Telephoto lens (1), mainframe box (2), the display screen (3) and support (4) of adjustable-angle.Wherein contain IMAQ and processing module and supplementary module in mainframe box (2).In automatic scoring round target device proposed by the present invention, its IMAQ and processing module will not be broken away from shooting target plate during ball firing；And can stay shelves as test result with existing artificial indication of shots means parallel practice, the target sheet of every shooter；All constituents in device mechanically link into an integrated entity, and simplify the erection procedure of device, reduce the erection time.The detection object of this scoring round target device is the target sheet at sharpshooter visual angle, and display point of impact is consistent with actual point of impact.
Description
Technical field
The invention belongs to target automatic detection report technical field, and in particular to it is a kind of based on telephoto lens it is portable from
Dynamic scoring round target device.
Background technology
Small arms ball firing training is the basic subject of the daily military training of army.At present, penetrated in most live shell
Hit in training, indication of shots is manually carried out, after one is shot round, by marker by showing target bar to achieving the result, this mistake
Journey time length, shooter can not be directly observed point of impact.
Due to the lifting of indication of shots means automaticity demand, the automatic scoring round target system based on various detection techniques also emerges in large numbers
Out.
Current most popular automatic scoring round target system is the electric pole short circuit sampling based on the soft conductive material of bilayer/multilayer
System (1, Huang Sheng,《The design and realization of automatic target-indicating machine》, data acquisition and procession, 1997, Vol.12, No.2:155~
158；2nd, scheme, Wang Zhuozhu etc. are prolonged in war,《The design and realization of a kind of automatic scoring round target system》, electronic measurement technique, 2008,
Vol.31, No.5:1~3；3rd, old silk ribbon, high source receipts etc.,《A kind of device of small arms ball firing automatic target-indicating and its work side
Method》, number of patent application：CN201310077701.0；4th, Chen Zaiwang, Wang Hong,《AVR single chip is in wireless automatic scoring round target system
Application》, micro computer is with applying, 2011, Vol.30, No.5:15~16.).The target body of this system is soft by conductive rubber etc.
Conductive material is constituted, and the change of relevant position resistance between electrode on target plate can be caused when target body is worn in group attack, so as to judge bullet
Position.In addition the system is also equipped with wireless transport module, and is placed on the display module near shooter, by point of impact position
It is shown to shooter in real time.Material is lossy in use for this system, thus cost is higher.Again because target sheet is interim patch
Up, it can be relatively moved with the calibration position of target plate circuit, thus cannot guarantee that target sheet real result and system meter
It is counted as achievement consistent.
Another kind of widely used hit telling system is the hit telling system based on photoelectric detecting technology.This system is mostly in target
Plate arranged in front photoemission and reception device, form the light curtain parallel with target plate, caused light when passing through light curtain by bullet
Line power change judges drop point site of the bullet on target plate.(1, Xi Kaidong,《A kind of radium-shine target automatic scoring round target device》, patent
Application number：CN201620947666.2；2nd, Wang Jianping,《Multi-layer sector optical curtain bullet projection locating target surface》, number of patent application：

CN201510633578.5；8th, Ning Xuanjing, Zhang Zhonghua,《Automatic scoring round target device》, number of patent application：CN201610352767.x).
The system fabrication and installation required precision is high, costly, and its operation principle is based on flying over light curtain this process to bullet
Capture, due to the limitation of light beam grid and time for exposure, High-velocity Projectiles are easily failed to report, and it cannot be guaranteed that actual falling point with
Detect that drop point is consistent.
An also class is the hit telling system based on image processing techniques.Video image letter of this kind of system based on target target plate
Breath, by image processing techniques, extract impact dot position information (1, Zhang Wei, Gao Hang,《Automatic report based on image processing techniques
Target system is designed and realized》, Nanjing Aero-Space University's journal, 2000, Vol.32, No.6:691~695.；2nd, Luo Jie, Zhang Zhi
It is bright,《Based on image processing techniques automatic scoring round target system summary》, laser magazine, 2016, Vol.37, No.7:1~6.；3rd, Zhang Xiao

CN201310249220.3；5th, Tang Jiaxing, Jiang Rongxin,《Indication of shots data interaction system based on image recognition and intelligent mobile terminal
System and method》, number of patent application：CN201610015192.2；6th, Jiang Guiping, Kuang Yong etc.,《A kind of intelligent hit telling system》, specially
Sharp application number：201510263274.4；7th, Li Yong,《A kind of automatic target-indicating method based on video analysis》, number of patent application：
CN201610728040.7).In these systems, although image processing method is had nothing in common with each other, but all it is by IMAQ in structure
Module is all placed near target plate, and display module is placed near commander and sharpshooter, passes through radio communication therebetween
Technology carries out signal transmission.In this kind of system, because the camera and target plate distance that gather video image information are near, generally using high
Elevation angle mode is placed, and does not have vertical relation between camera optical axis and target surface, and the slight bumps of target sheet all cause the mistake of topography
It is true and block；In addition the high elevation angle causes camera cisco unity malfunction it is also possible to cause periods of direct sunlight.
Based on ultrasonic sensor automatic scoring round target system (1, Huang Keping, Wu Gaoqiang etc.,《Horizontal is structured the formation ultrasonic automatic
Hit telling system》, number of patent application：CN200410014100.6；2nd, Tang Yong, Liu Xiaohong,《Triangle is structured the formation ultrasonic automatic target-indicating system
System》, number of patent application：CN201610210511.5；3rd, Chen Xiangchun, Li Peng's brightness etc.,《Curve distribution formula shock wave automatic target-indicating system
System》, number of patent application：CN201510267871.4), it is also current study hotspot.This hit telling system is passed through using bullet
The shock wave produced during cavity target plate judges point of impact position of the bullet on target plate, affected by environment big, it is difficult to be accurately positioned.
In addition, also have based on pressure sensor automatic scoring round target system (Dong Bo,《Automatic target-indicating based on pressure sensor
Device》, number of patent application：CN201310485052.8), the two-layer electrode short circuit sampling of rigid conductive material is supported based on spring
System (1, Li Ruijie, LI XUEMEI etc.,《Live shell target Design of automatic report target system and research》, digital technology is with applying, and the 2014, the 4th
Phase, 104；2nd, yellow hairdressing, Li Zuyu etc.,《Automatic target-reading device of live ammunition target》, number of patent application：CN200920140604.0) etc. no
The hit telling system of same type, but it is introduced into the practical stage at present.
In any of the above automatic scoring round target system, detection module and achievement display module are discretely located, and erection process is complicated,
And detection module is usually placed on shooting target plate or near target plate, is easily broken by bullet.Except based on image processing method
Outside scoring round target device, other types of scoring round target device is it cannot be guaranteed that as the actual falling point position on the target sheet of track record with surveying
Measure position consistency.
