Description
Technical Field
The invention relates to the technical field of shooting training equipment, in particular to a grating target scoring system and an automatic target scoring system comprising the same.
Background
In shooting sports and shooting training, assessment and competition of troops, target showing, target checking and score recording are very important work contents. Therefore, the research on the automatic target scoring system is very significant.
According to the technical principle of automatic target scoring, the existing automatic target scoring system can be divided into an electrode embedding mode, a photoelectric sensing mode, an image processing mode and an acoustoelectric positioning mode.
The electrode embedding mode is that in the production process of the special target body, a two-dimensional grid formed by electrodes is embedded in an interlayer of the target body. When the spacing between every two electrodes is smaller than the diameter of the bullet or shell in the vertical and horizontal directions, the target body is cut off by each bullet or shell to break down the target body. The position of a bullet or a cannonball hitting a target body can be determined by measuring the resistance value change between electrodes with different numbers, so that the coordinates of the bullet points are formed, and the number of rings is judged.
In the photoelectric sensing type automatic target scoring system, two sets of high-sensitivity photoelectric receiving and transmitting devices (such as light emitting diodes and photosensitive diodes) are correspondingly arranged around a target body in the vertical direction and the horizontal direction. The light emitted by the two groups of densely arranged light-emitting devices divides the target into a matrix grid shape. Each small grid corresponds to a square area on the target. The combination of the numbers of each set of photoelectric devices in the vertical direction and the horizontal direction is the coordinate of the corresponding point on the target. Under the condition that the distance between every two adjacent photoelectric devices is smaller than the diameter of a bullet or a cannonball, at least two rays of light can be cut off in the vertical direction and the horizontal direction at the moment that the bullet or the cannonball passes through the target body every time, and the change of the brightness of the light changes the electrical parameters of the photosensitive devices. Therefore, the numbers of the photosensitive devices can be collected to form the coordinates of the impact points, and then the number of the rings of the impact points is obtained by means of table lookup and the like. The photoelectric sensing type automatic target-scoring system has higher requirements on the collimation and the cross-sectional area of a light beam, and a transmitting device is formed by combining a laser diode and a lens, so that a better effect can be achieved. The receiving device employs a photodiode. This system requires that the photodiode be able to detect the rapid blocking of the light path by the bullet, which is mainly determined by the response time of the photodiode.
The automatic target scoring system of the image processing technology uses a camera to collect a conventional standard target picture, finds out real bullet points in the target picture by using a computer image recognition technology according to the characteristics and the change of the collected target picture, and then confirms the ring number value of the bullet points by judging the positions of the bullet points in the target.
An automatic target scoring system based on the sonic explosion effect is a typical system in the acoustoelectric positioning automatic target scoring system. The acoustoelectric positioning automatic target scoring system can realize the position positioning of the bullet or the shell by measuring the shock wave of the projectile of the supersonic flying bullet or the shell or the pressure induced by the projectile under specific conditions.
The automatic target scoring system has the common problems that the environmental adaptability is poor, when a target vehicle passes through a complex road surface with unevenness and the like, the automatic target scoring function cannot be accurately finished, only a single target scoring technical guarantee is provided, the automatic target scoring system cannot be used when the system breaks down, and the reliability is poor.
