Problems solved by technology

One of these two methods requires installing a photoelectric positioning probe inside or around the target, which not only increases the difficulty of target paper processing itself, but also makes daily maintenance more complicated.
The existing target paper has a rubber target paper that can be used repeatedly, which can be reused many times. Live ammunition can penetrate directly, and manual target reporting cannot be realized at all.
[0003] At present, the rubber target paper with self-closing performance (due to the self-closing performance, only a small impact point is left after the bullet passes through, with a diameter of about 1mm). When the number of training increases, it is very difficult to distinguish dense impact points using conventional methods. Difficult, it is difficult to locate the impact point of the bullet, and it is impossible to achieve accurate detection and intelligent output of the shooting results, which affects shooting training

Embodiment 1

[0088] Embodiment 1, the mapping processing algorithm of the impact point mapping module 400 is as follows:

[0089] S411 acquire data, acquire the information data corresponding to the outline of the design drawing of the forward image of the target design model; acquire the information data corresponding to the outline of the real picture in the actually shot side image;

[0090] The information data acquisition of the corresponding design drawing outline of the forward image of the target design model is specifically, according to the design of the target by the manufacturer, the frontal image of the target is obtained (such as Figure 5-1 ); Afterwards, the image is processed to calculate the overall outline of the image and the starting position of the outline map in the design drawing (such as Figure 5-2 ).

[0091] The acquisition of the information data corresponding to the outline of the real picture in the lateral image of the actual shooting is specifically, obtai...

Embodiment 2

[0098] Embodiment 2, the mapping processing algorithm of the impact point mapping module 400 is as follows:

[0099] S421 acquires data, and acquires three-dimensional model data of the target;

[0100] Obtain the 3D model data of the target. The target has a corresponding design drawing when it is produced, and the designed model data can be used directly (this data can be directly obtained according to the manufacturer of the target).

[0101] S422 Obtain the mapping table, make a mark point on the target, identify the position of the mark point on the image through the impact point detection algorithm, and record a point P(P x , P y ,P z ) and a point P on the image (P u , P v ) correspondence; after marking all positions, a P(P x , P y ,P z )P(P u , P v ) mapping table, store the mapping table in the system;

[0102] To make a mark on the target, you can use a high-temperature object to mark on the target, such as inserting a red-hot iron wire into the target, an...

Embodiment 3

[0107] Embodiment 3, the mapping processing algorithm of the impact point mapping module 400 is as follows:

[0108] S431 Acquire data, obtain the three-dimensional model data of the target, the parameters of the thermal camera, and the relative positional relationship between the thermal camera and the target, so as to obtain a virtual shooting image;

[0109] 1.1 Obtain the 3D model data of the target first. The target has corresponding design data when it is produced, and the designed model data can be used directly (this data can be obtained directly according to the target manufacturer), or the target can be reconstructed by 3D reconstruction and other methods. 3D data;

[0110] 1.2 Obtain the parameters of the thermal camera (camera). The camera is calibrated when it leaves the factory; therefore, you can directly use the internal parameters of the camera provided by the manufacturer; In the existing technology, the calibration principle of the camera is the same as tha...

Abstract

The invention discloses an intelligent scoring system and method for shooting and shooting. Target shooting visual collection, image collection processing, processing of raw data obtained by a thermal camera to generate images that are convenient for detection and observation; impact point detection processing, based on the generated images, identification The position of the impact point in the image; the impact point mapping processing, mapping the impact point in the image position and the position of the impact point on the target, and finally calculating and restoring the actual position of the bullet hitting the target; scoring processing , scoring grades by definition. This design scheme takes the thermal energy analysis of the bullet as an important reference factor for target identification, uses the principle of thermal imaging, and uses the original data of the thermal camera to reconstruct its data, and uses the correlation mapping algorithm to accurately and high-precision the impact point of the bullet. Positioning, and finally get a highly accurate intelligent scoring effect, which greatly improves the effectiveness of shooting training.

Description

technical field [0001] The invention relates to the field of intelligent processing devices and technologies, in particular to an intelligent scoring system and method for shooting and shooting. Background technique [0002] At present, the target reporting methods of the existing shooting training systems at home and abroad include the photoelectric positioning method of the actual impact point or the manual target reporting method of the paper screen. One of these two methods needs to install a photoelectric positioning probe inside or around the target, which not only increases the difficulty of processing the target paper itself, but also makes the daily maintenance more complicated. Existing target paper has rubber material target paper that can be used repeatedly, which can be reused many times. Live ammunition directly penetrates, and artificial target reporting cannot be realized at all. [0003] At present, the rubber target paper with self-closing performance (due...
