Description

Technical Field

[0001] The utility model relates to the technical field of automatic target marking, in particular to a full-automatic target marking system and a target marking method based on GPRS wireless transparent transmission. Background Art

[0002] Currently, target registration systems on the market are primarily divided into manual and automatic systems. Traditional manual systems suffer from flaws such as false alarms and low security, and manual registration requires a long time and a high workload. Existing automatic systems, such as the indoor automatic target registration device based on image processing technology produced by Nanjing Ruichen Xinchuang, utilize the target's ability to freely move between the shooting range and the ammunition collection device, controlled via a computer network. However, this traditional image processing-based automatic target registration system, due to its high deployment and maintenance costs and low environmental adaptability, cannot meet the requirements of real-world shooting training.

[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 in 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 impact positions and bullet holes on the target. The data is processed by the industrial control computer and then sent to a single-soldier briefcase through wireless transparent transmission, allowing soldiers to observe their 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. Utility Model Content

[0022] Specific implementation method 1. Combination Figures 1 to 5 This embodiment describes a fully automatic target marking system based on GPRS wireless transparent transmission, which includes a target marking 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;

[0023] The target reporting camera system 10 automatically identifies the target position of the target 40 and transparently transmits the target position information of the identified target to the individual display system 30 and the remote control and display terminal 50.

[0024] like Figure 2 As shown, the target reporting camera system includes a bottom moving frame 11, a target seeking assembly 12, a first radio station 16, a first antenna 17, an industrial computer assembly 18 and a waterproof power supply compartment assembly 19.

[0025] The entire target camera system is powered by a waterproof power supply compartment assembly 19. The industrial computer assembly 18 and the waterproof power supply compartment assembly 19 are equipped with cooling mechanisms such as fans, thermal pads, and shutters. Each assembly contains a temperature detection device. The temperature is transmitted to the remote control and display terminal 50 via a first radio station 16 and a first antenna 17. When the temperature exceeds 35°C, the remote control and display terminal 50 activates the cooling fan to dissipate heat. The industrial computer assembly 18 is responsible for image data storage, display, and processing. The bottom mobile frame 11 of the target camera system 10 features a wheelless design, allowing it to be placed in a variety of environments.

[0026] In this embodiment, the target-finding assembly 12 integrates five zoom cameras 15, three tilt mechanisms 13, and five rotating stages 14 to achieve target-finding functionality. Each zoom camera utilizes a 4K HD 40x optical zoom network-integrated core. Its internal zoom mechanism allows for a variable focal length from 6.0mm to 240mm. From left to right, the zoom cameras are numbered 1 through 5. Zoom cameras 1-5 are mounted on a rotating stage 14 with a φ40mm surface. Driven by a servo motor within the stage 14 and employing a high-precision worm gear mechanism, each achieves a repeatable positioning accuracy within ±5°. The rotating stage 14 controls the rotation angles of zoom camera 1 between 0° and 45°, zoom camera 2 between 0° and 25°, zoom camera 3 between ±15°, zoom camera 4 between -25° and 0°, and zoom camera 5 between -45° and 0°.

[0027] In this embodiment, the pitch mechanisms are defined as No. 1 to No. 3, from left to right. These mechanisms are mounted on the bottom surface of the rotating platform and rigidly connected using screws. The rotating platform can tilt synchronously with the pitch mechanisms, thereby controlling the zoom cameras mounted on the platform. Specifically, pitch mechanism No. 1 is mounted on the bottom surfaces of rotating platforms No. 1 and No. 2, controlling the pitch angles of zoom cameras No. 1 and No. 2; pitch mechanism No. 2 is mounted on the bottom surface of rotating platform No. 3, controlling the pitch angles of zoom cameras No. 3; and pitch mechanism No. 3 is mounted on the bottom surfaces of rotating platforms No. 4 and No. 5, controlling the pitch angles of zoom cameras No. 4 and No. 5. The pitch mechanisms are controlled by electric push rods. The pitch angles of pitch mechanism No. 1, No. 2, and No. 3 are 0-20°, respectively. Each zoom camera has three degrees of freedom that can be controlled. During the target search process, the zero position function of the rotating stage is first 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.

[0028] In this embodiment, the target-finding function of the target-reporting camera system extracts the lowest-resolution image data from the camera data stream. First, the remote control and display terminal 50 sends a target-finding command to the industrial computer component 18. The industrial computer component 18 analyzes the image data captured by each zoom camera in the target-finding component 12 to obtain the coordinates of the current target and the ratio of the target to the field of view corresponding to each zoom camera. The image resolution is 720*1280. The target-finding output is the coordinates of the target center point across the entire field of view and the ratio of the target to the field of view. The output is the coordinates (x, y, K), where (x, y) is the deviation of the target center point relative to the field of view center, and K is the ratio of the target to the field of view. After each zoom camera finds its own target, it performs a zoom operation. When the target target 40 is magnified 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. 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. Finally, the target reporting result is output and displayed.

[0029] In this embodiment, the target reporting result display is divided into three situations.

[0030] 1. When there are bullet holes on the target paper, and it is the output result under normal working conditions.

[0031] a) Determine the effective area of the target and whether it is off-target.

[0032] b) Perform target ring detection on the target paper, determine the score, and output the final score.

[0033] c) Output the coordinates of the bullet hole position.

[0034] 2. Output results when there are no bullet holes or abnormal conditions: that is, the target camera system is operating normally, but no shooting operation is performed, and the shooting result is directly output as empty.

[0035] 3. Equipment abnormality, including equipment contamination, target paper missing, etc.

[0036] If the output result is abnormal, the device will send an abnormal code to the remote control and display terminal, which will be transferred to manual operation to detect the abnormality of the system. The target reporting camera system transmits various target reporting results from the first radio station 16 to the individual display system 30 and the remote control and display terminal via the first antenna 17.

[0037] like Figure 3 As shown, the environment detection system 20 includes a temperature and humidity sensor 21, a first power supply 22, a wind speed sensor 23 and a third radio station 24;

[0038] The environmental detection system 20 is powered by a first power supply 22 , the temperature and humidity sensor 21 detects the temperature and humidity of the shooting range environment, 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 soldier display system 30 .

[0039] like Figure 4 As shown, the interior of the individual soldier display system 30 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;

[0040] The individual soldier display system 30 is powered by a second power source 31. It receives real-time wind speed, temperature, and humidity data transmitted by the third radio station 24 of the environmental monitoring system, as well as target position information of five targets transmitted by the first radio station 16 of the target reporting camera system, via a second radio station 34. This target position information, consisting of two sets of ring counts and azimuths, is transmitted to the soldier's ear in real time via an individual headset 32. The individual soldier display system 30 processes this information and displays it on an individual display screen 35. This allows the soldier to observe the current environmental conditions and target position information in real time, guiding their next practice.

[0041] In this embodiment, the remote control and display terminal 50 is used to issue commands and receive information. It can simultaneously control several sets of target camera systems 10 to perform target search operations, and can synchronously receive the shooting information of each soldier transmitted back by several target camera system radio stations 16, and summarize and archive the final results.

[0042] In the target-marking camera system 10 described in the present invention, the target-marking camera system is placed 10-20m in front of the target, and the position deviation between the No. 3 zoom camera and the middle target of the five targets in the target-marking camera system is controlled within ±1m. The target-marking camera system can meet the automatic target-marking function when the inclination angle with the target is not greater than 30°.

[0043] 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.

[0044] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
