Description

Technical Field

[0001] This invention relates to the field of artillery shell guidance technology for military weapons, specifically to an intelligent guidance device for artillery shells based on image recognition and real-time attitude control. Background Technology

[0002] Traditional artillery shells cannot autonomously correct their trajectory during flight. Their landing point mainly depends on the trajectory calculation before firing, and is easily affected by factors such as wind speed, air pressure, terrain and target movement, resulting in a low hit rate.

[0003] Existing guidance methods mostly rely on laser, radar, or satellite positioning, which have drawbacks such as susceptibility to interference, high cost, and the need for continuous external guidance. To address these shortcomings, this invention proposes a projectile guidance device capable of autonomously identifying targets and adjusting its flight attitude in real time, thereby significantly improving the hit probability. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an intelligent guidance device for artillery shells. It includes a video input module, an image recognition and processing module, a path planning module, an output action command module, and a rudder module. During the shell's flight, the video input module transmits images in real time to the image recognition module. When the image recognition module detects a target, it locks onto the target with an optimal trajectory. The image recognition module detects the target's position and distance on the screen, calculates the optimal flight path, and outputs adjustment control direction commands to the rudder control module, thus controlling the shell's flight direction in a closed loop. This enables the shell to autonomously lock onto the target and correct its trajectory during flight, achieving flight direction adjustments until a hit is achieved.

[0005] The present invention adopts the following technical solution: A smart guidance device for artillery shells, used in military artillery shells, includes: a video input module, an image recognition and processing module, a path planning module, an output action command module, and a rudder module.

[0006] The video input module is used to acquire real-time video footage of the projectile's flight path. This module can use a camera with infrared or thermal sensing capabilities, enabling it to acquire clear target images in complex environments such as day and night.

[0007] The image recognition processing module has a pre-trained target recognition model built in. Through extensive image annotation and deep learning training on targets such as tanks, armored vehicles, and individual soldiers, the module is equipped with the ability to autonomously identify and lock onto designated targets, and can set priority target types according to operational needs.

[0008] Once the image recognition module locks onto the target, the path planning module obtains the target's location information based on image recognition processing and calculates an optimal flight path for the projectile based on its real-time flight attitude.

[0009] The output action command module calculates the trajectory deviation based on the interpreted projectile flight path and generates corresponding directional control commands, which are then sent to the rudder module.

[0010] The rudder module is the projectile's directional actuator. It receives control signals from the output action command module and controls the rudder deflection via a micro motor to adjust the projectile's flight direction, achieving real-time trajectory correction.

[0011] A smart guidance device for artillery shells includes the following steps:

[0012] 1. Load the trained target recognition model into the image recognition processing module and select the priority target type for this attack. Before launch, attach the device to the threaded head at the front of the projectile via the internal thread interface.

[0013] 2. After the shell is fired, the video input module continuously captures real-time images of the environment ahead and transmits them to the image recognition and processing module.

[0014] 3. The image recognition and processing module performs real-time detection of the image, identifies and locks onto the optimal target.

[0015] 4. The path planning module calculates the optimal control flight route based on the locked target, its orientation, and distance.

[0016] 5. Output action command module, which generates control rudder action signal commands based on target azimuth deviation and the current attitude of the projectile.

[0017] 6. The rudder module executes the commands for controlling direction. Upon receiving output action information commands, it controls the micromotor of the rudder to change direction, thereby controlling the projectile's flight attitude and continuously correcting its trajectory until it accurately hits the target.
