Description
Technical field
The present invention relates to gunnery training fields, specifically provide a kind of real-time automatic scoring round target system.
Background technology
Ball firing is the grounding examination item of the departments such as public security, People's Armed Police, army, and the indication of shots of these departments at present
Mode mainly uses artificial indication of shots, that is, after the completion of shooting, the point of impact of target surface target sheet is estimated, by counting point of impact one by one
Mode carries out indication of shots.This indication of shots mode compares the efficiency for influencing gunnery training, Bu Nengshi higher to indication of shots personnel qualifications
When report number of rings information.
For automatic target-indicating problem, there is the automatic scoring round target system based on various sensors, as acoustic-electric positions automatic target-indicating
The target surface of system, photoelectric sensor automatic scoring round target system etc., such system is made of the smaller sensor of some sizes, sensor
It is connected with integrated circuit, IC system handles the signal generated when bullet impact microphone, so that it is determined that impact
The position of point.This hit telling system can generally accomplish very high accuracy, but target surface cost is relatively high, as sensor is beaten
The factors such as bad, the service life of each target surface is shorter, and due to electronics target surface, does not have the impact information of picture, unfavorable
In the analysis to trainer's training.
The existing automatic target-indicating method based on video analysis, preshot remove target surface image using datum mark geometric correction
Distortion, establishes target surface parameter model on the target surface image of correction, in shooting course, the target surface image sequence of analysis acquisition in real time
Row, it is determined whether shooting behavior has occurred, when shooting behavior occurs, shell hole is determined according to the target surface parameter model having built up
Number of rings.This method has judged whether to shooting by the way of frame difference, gunnery target is shaken, illumination variation, even hole etc.
In the case of, it be easy to cause wrong report or fails to report；Shell hole number of rings is determined using the target surface parameter model of the foundation of preshot, for penetrating
The number of rings hit under process target surface jitter conditions determine can exist error, especially loop wire nearby shell hole number of rings determination there may be
Large error.
For existing automatic scoring round target system, sensor automatic scoring round target system is of high cost, now with video analysis automatic target-indicating
The not high problem of system accuracy, those skilled in the art provide a kind of real-time automatic scoring round target system, to solve above-mentioned background skill
The problem of being proposed in art.
