Description
Technical field
The present invention relates to a kind of automatic scoring round target device, and in particular to a kind of automatic scoring round target device.
Background technology
In modern military training, target practice is one of essential military training project；Also have increasing simultaneously
People regard shooting sports as the hobby of oneself.
In the past, artificial indication of shots (the i.e., number of rings that bullet is passed through) is used during ball firing, still, due to it
Have that security is poor, the low many drawbacks of efficiency, therefore, automatic scoring round target device arises at the historic moment and instead of artificial indication of shots, its energy
The drawbacks of enough efficiently solving artificial indication of shots.
Existing automatic scoring round target device mainly has image procossing coordinate target, acoustic-electric coordinate target etc., but they are all mostly
Based on the sensor on target, so, due to being limited to target material problem, cause target frequent breakage, make
The training cost that must practice shooting remains high.
In addition, image procossing coordinate target is that by image capturing system Physical Target is converted into digital picture, then to mark
The image of target is handled, and the number of rings drawn is exported to display interface.The core of the system is image processing system, at it
The quality of adjustment method directly affects the accuracy of final target number, by acquired image determine the position of shell hole and pinwheel with
And distance and the transforming function transformation function of target number, you can calculate number of rings.But the automatic scoring round target device can not ensure to be used to gather physics
Strict vertical relation between the camera and target target disc of image, and target disc microrelief, can all influence become exchange the letters
Several linear property, and the collection result of image is influenceed larger by illumination, it is impossible to adapt to the round-the-clock requirement used.
Acoustic-electric coordinate target is that several acoustoelectric sensors are housed on a rectangular frame.When bullet is passed through out of framework,
Air in impact frame is allowed to produce disturbance, is formed around an impact wave direction and spreads (bullet crossing point is wave source), from
The nearest sensor of wave source captures the ripple at first, starts inspection target instrument and starts timing, remaining each sensor is sequentially received the ripple,
Several time differences are thus obtained, by the speed (velocity of wave) of these time differences and bullet, calculation process are carried out, it is possible to
The position of wave source, i.e. bullet are obtained through position.But, the automatic scoring round target device is easily influenceed by environmental noise, causes measurement
Lack accuracy, moreover, two interference sent out between bullets of the influence and continuous fire between adjacent target position are also relatively large, to making
It is harsh with environmental requirement.
