[0002] At present, the target reporting systems on the market are mainly divided into manual target reporting systems and automatic target reporting systems. The traditional manual target reporting system equipment has defects such as human false alarms and low safety, and manual target reporting takes a long time and a lot of work. For the existing automatic target reporting systems, such as the indoor automatic target reporting equipment based on image processing technology produced by Nanjing Ruichen Xinchuang Company, it uses the target to move freely between the shooting site and the bullet collector and is controlled through a computer network. However, this automatic target reporting system based on traditional image processing technology cannot meet the shooting training requirements in actual environments due to its high layout and maintenance costs and low environmental adaptability.

[0003] The fully automatic target reporting system of the present invention is used to guide military shooting training. It is suitable for garrison training grounds and can also be used for combat troops' live-fire test grounds. It is not restricted by the external environment and uses high-precision photoelectric sensing equipment and computer algorithms to measure and analyze the strike positions and bullet holes on the target. The data is processed by an industrial computer and sent to a single-soldier briefcase through a wireless transparent transmission method, so that the soldiers can observe their own shooting positions in real time. At the same time, the high-precision identification of bullet hole points can greatly help improve the overall shooting ability. Summary of the invention

[0028] Specific implementation method 1. Combination Figures 1 to 5 The present embodiment is described as a fully automatic target reporting system based on GPRS wireless transparent transmission, which includes a target reporting camera system 10, an environment detection system 20, a target 40, a single soldier display system 30 and a remote control and display terminal 50;

[0029] The target reporting camera system 10 automatically identifies the target position of the target 40 , and transmits the target position information of the identified target to the individual soldier display system 30 and the remote control and display terminal 50 .

[0030] like Figure 2 As shown, the target reporting camera system includes a bottom moving frame 11, a target finding component 12, a first radio station 16, a first antenna 17, an industrial computer component 18 and a waterproof power supply compartment component 19.

[0031] The whole target camera system is powered by the waterproof power compartment assembly 19. The industrial computer assembly 18 and the waterproof power compartment assembly 19 are integrated with heat dissipation structures such as fans, thermal pads, and shutters. There is also a temperature detection device inside the industrial computer assembly 18 and the waterproof power compartment assembly 19. The temperature value is transmitted to the remote control and display terminal 50 through the first radio station 16 and the first antenna 17. When the temperature exceeds 35°C, the remote control and display terminal 50 calls the cooling fan to work for heat dissipation. The industrial computer assembly 18 is responsible for the storage, display and processing of image data. The bottom mobile frame 11 of the target camera system 10 can be placed in various usage environments due to its wheel-free design.

[0032] In this embodiment, the target-seeking component 12 integrates five sets of zoom cameras 15, three sets of pitch mechanisms 13, and five sets of rotating platforms 14 to realize the target-seeking function. Each set of zoom cameras uses a 4K high-definition 40x optical zoom network integrated movement, and its internal zoom mechanism can achieve a camera focal length change from 6.0mm to 240mm. From left to right, the zoom cameras are numbered 1 to 5. Zoom cameras 1-5 are respectively mounted on a rotating table 14 with a table size of φ40mm, and are driven by a servo motor inside the rotating table 14 and a high-precision worm gear mechanism, with a repeat positioning accuracy within ±5″; the rotating table 14 has integrated zero position and limit functions, which are used to control the rotation angle of zoom camera No. 1 to 0°~45°, the rotation angle of zoom camera No. 2 to 0~25°, the rotation angle of zoom camera No. 3 to ±15°, the rotation angle of zoom camera No. 4 to -25°~0°, and the rotation angle of zoom camera No. 5 to -45°~0°.

[0033] In this embodiment, the pitch mechanisms are defined as No. 1 to No. 3 in order from left to right. The pitch mechanisms are installed on the bottom surface of the rotating platform and connected by a screw rigid connection method. The rotating platform can be synchronously pitched according to the pitch mechanisms to control the zoom camera placed on the platform. That is, the pitch mechanism No. 1 is installed on the bottom surface of the rotating platforms No. 1 and No. 2 to control the pitch angles of the zoom cameras No. 1 and No. 2, the pitch mechanism No. 2 is installed on the bottom surface of the rotating platform No. 3 to control the pitch angle of the zoom camera No. 3, and the pitch mechanism No. 3 is installed on the bottom surface of the rotating platforms No. 4 and No. 5 to control the pitch angles of the zoom cameras No. 4 and No. 5. The pitch mechanism is pitch-controlled by an electric push rod, and the pitch angle of the pitch mechanism No. 1 is 0-20°, the pitch angle of the pitch mechanism No. 2 is 0°-20°, and the pitch angle of the pitch mechanism No. 3 is 0°-20°. Each zoom camera has three degrees of freedom that can be adjusted. During the target search process, the zero position function of the rotating stage is used to control the initial position of each camera to face forward. The camera's internal focusing mechanism is used to adjust the camera's field of view so that all five targets in front can be seen.

[0034] In this embodiment, the target-seeking function of the target-reporting camera system is to extract the image data with the lowest resolution from the camera data stream. First, the remote control and display terminal 50 sends a target-seeking instruction to the industrial computer component 18. The industrial computer component 18 analyzes the image data captured by each zoom camera in the target-seeking component 12 to obtain the coordinate value of the current target corresponding to each zoom camera and the ratio between the target and the field of view. The image resolution is 720*1280, and the output of the target-seeking is the coordinate value of the entire field of view where the center point of the target is located and the ratio of the target filling the field of view. The output result is the coordinate (x, y, K), where (x, y) is the deviation of the target center relative to the center of the field of view, and K is the ratio of the target filling the field of view. After each zoom camera finds its own target, it performs a zoom operation, and when the target target 40 is enlarged to 8 / 9 of the field of view, the target reporting operation is performed; the target reporting function of the target reporting camera system 10 is to transmit the images taken by each zoom camera to the industrial computer component 18, and the industrial computer component processes the image, extracts the effective area of ​​the target paper, obtains the chest ring target detection, and then performs bullet hole recognition processing, and finally outputs and displays the target reporting result.

[0035] In this embodiment, the target reporting result display is divided into three situations.

[0036] 1. When there are bullet holes on the target paper, and it is the output result under normal working conditions.

[0037] a) Determine the effective area of ​​the target to determine whether it is off-target.

[0038] b) Perform target ring detection on the target paper, determine the score, and output the final score.

[0039] c) Output the coordinates of the bullet hole position.

[0040] 2. Output results when there are no bullet holes or abnormal conditions: that is, the target reporting camera system works normally, but no shooting operation is performed, and the shooting result is directly output as empty.

[0041] 3. Equipment abnormality, including equipment contamination, target paper missing, etc.

[0042] The target reporting camera system sends various target reporting results from the first radio station 16 transmitting end to the individual display system 30 and the remote control and display end via the first antenna 17.

[0043] like Figure 3 As shown, the environment detection system includes a temperature and humidity sensor 21, a first power source 22, a wind speed sensor 23 and a third radio station 24;

[0044] The environment detection system 20 is powered by a first power source 22, the temperature and humidity of the shooting range environment is detected by a temperature and humidity sensor 21, the wind speed sensor 23 detects the wind speed of the shooting range, and finally the third radio station 24 transmits the data via an antenna to the individual display system 30.

[0045] like Figure 4 As shown, the interior of the individual soldier display system integrates a second power supply 31, an individual soldier headset 32, a second antenna 33, a second radio station 34 and an individual soldier display screen 35;

[0046] The individual soldier display system 30 is powered by a second power supply 31, and receives the wind speed, temperature and humidity real-time data transmitted by the third radio station 24 of the environment detection system and the target position information of the five targets transmitted by the first radio station 16 of the target reporting camera system through the receiving end of the second radio station 34. The target position information includes two groups: the number of rings and the direction. The target position information is transmitted to the soldier's ears in real time through the individual soldier headset 32. The individual soldier display system 30 processes various information and displays it on the individual soldier display screen 35. The soldier can observe the current environmental status and target position information in real time to guide the soldier's next shooting operation.

[0047] In this embodiment, the remote control and display terminal 50 is used for issuing commands and receiving information. It can simultaneously control several sets of target camera systems 10 to perform target searching operations, and can synchronously receive the shooting information of each soldier transmitted back by the first radio stations 16 of several target camera systems, and summarize and archive the final results.

[0048] In the target reporting camera system described in the present invention, the target reporting camera system is placed 10-20m in front of the target, the position deviation between zoom camera No. 3 and the middle target of the five target targets in the target reporting camera system is controlled within ±1m, and the automatic target reporting function can be satisfied when the inclination angle between the target reporting camera system and the target target is not greater than 30°.

[0049] Specific implementation method 2: Combination Figure 6 This embodiment is described. This embodiment is a method for marking a target using the fully automatic marking system based on GPRS wireless transparent transmission described in the specific embodiment 1. The method is implemented by the following steps:

[0050] Step 1: Initialize the fully automatic target reporting system; that is, the target reporting camera system, the environmental detection system, and the individual soldier display system are initialized for self-inspection, and start normally after the self-inspection is normal. If there is a problem, re-initialize the self-inspection;

[0051] Step 2: The remote control and display terminal 50 starts the target reporting camera system 10 by one-key control, and the target reporting camera starts to automatically search for targets, and transmits the target search results to the remote control and display terminal 50 and the individual soldier display system 30 respectively through the radio station 16.

[0052] Step 3: The environment detection system 20 is started, and the wind speed and temperature and humidity values ​​detected by the wind speed sensor 23 and the temperature and humidity sensor 21 are transmitted to the remote control and display terminal 50 and the individual display system 30 respectively.

[0053] Step 4: The individual soldier display system is started, and the information received through the radio station is displayed on the individual soldier display screen.

[0054] Step 5: The remote control and display terminal 50 receives the target shooting information of each soldier transmitted back by the target reporting camera system, and summarizes and archives the final results; target recognition is completed and the test ends.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
