Problems solved by technology

The above methods are not only inefficient, and the accuracy of naked eye observation cannot be guaranteed when there are multiple bullet holes on the target, but also pose a certain threat to the safety of the target reporting personnel, and there is a great potential safety hazard
The second-generation target shooting system adopts a semi-automatic method. The existing technology can realize target reporting or target replacement alone, but due to technical reasons, it is difficult to combine target reporting and target replacement to realize fully automatic target reporting and target replacement.
This method is more difficult to control, and the distance between the target position unit and the roller is not easy to determine, and requires on-site debugging by technicians; the other usually requires a larger storage box to store the target paper, and because the box is larger, often It needs to be installed under the ground, causing great difficulties for installation
Due to the different ways of implementation, the above schemes can only achieve single target reporting or target paper replacement, which is inconvenient for fully automatic target shooting training, low efficiency, and there is a certain degree of danger when artificially assisted
In addition, the existing target shooting system is relatively complicated to install, and it is difficult to adapt to motorized training
[0006] At present, there are mainly two methods for realizing automatic target reporting: one is to install sensors on the target unit, and obtain the shooting results by processing the sensor signals. This method requires a special target unit, which is expensive and the sensor is easily damaged. It is difficult to change the target; the other is to install a scaffold with a fixed camera above the target unit, and obtain the target shooting results by processing image information. This method has high requirements on the mechanical structure of the site, is not easy to install, and is not convenient for motorized training.

Embodiment 1

[0042] Such as Figure 1-Figure 4 As shown, this embodiment provides a target shooting system capable of automatic target reporting and target replacement, including a target carton 9 with an open upper end, a target paper acquisition unit, a target paper delivery unit, a target paper fixing unit, a target position unit, and target information collection unit, the target paper box 9 is vertically stacked with multiple layers of target paper 10; state; the target paper transfer unit can transfer the target paper acquisition unit and the adsorbed target paper 10 directly above the target paper fixing unit; the target paper fixing unit can support the target plate in a horizontal state, and the target paper fixing unit includes a glue spraying mechanism. The glue mechanism can spray glue to the surface of the target plate to bond and fix the target plate and the target paper 10 released by the vacuum suction cup 18 assembly; Toggle between horizontal orientations.

Embodiment 2

[0081] This embodiment provides a method for automatic target reporting and target replacement, utilizing the target shooting system described in Embodiment 1 that can realize automatic target reporting and target replacement, including the following steps:

[0082] After the installation of the shooting system capable of automatic target reporting and changing, the targets are arranged vertically, and the shooting personnel shoot towards the target at a set distance; after each shooting, use the telescope set on the shooting personnel's side to collect distant target boards The high-definition camera can capture the image from the telescope and transmit it to the shooting information processing unit for image analysis to judge the shooting information.

[0083] Using image recognition to judge the shooting performance, the operator judges whether the target paper 10 needs to be replaced, when necessary, the target in the target unit is rotated to a horizontal state, and the ta...

Embodiment 3

[0090] A target image processing algorithm proposed in this embodiment consists of Image 6 As shown, it specifically includes the following steps:

[0091] 1. Targeting image preprocessing: After shooting the shooting image, first convert the image into a grayscale image, then perform Gaussian filtering to remove the noise generated during image transmission, and then perform histogram equalization to overcome the interference of light intensity changes , save the preprocessed image (gray_Image).

[0092] 2. Judging whether it was shot or not: make a difference with the last saved image to obtain a frame difference image. (difference_Image), binarize and sum the frame difference images, because the size and area of ​​the actual bullet holes are relatively fixed, so a threshold interval is artificially set according to the area of ​​the bullet holes, and the summed image is compared with the set threshold , if it is within the threshold interval, it is considered that the ta...

Description

technical field [0001] The present disclosure belongs to the technical field of target shooting, and in particular relates to a target shooting system and method capable of realizing automatic target reporting and target changing. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Target practice is one of the indispensable daily training for soldiers or athletes. During training, it is usually necessary to obtain target shooting results in real time (this work is also called target reporting); when the target paper cannot clearly mark the results, it is necessary to replace the target paper (this work is called target replacement); and due to training or confidentiality needs, the target shooting device It is often necessary to change the location, which also puts forward higher requirements for the complexity of the structure of the shooting system...
