Technical Field

[0001] This invention relates to the field of target location detection, and in particular to a target location detection method and apparatus based on a hardware-in-the-loop simulation system. Background Technology

[0002] In hardware-in-the-loop simulation systems, target simulators are typically used to test the functionality and performance of a weapon system. There are many types of simulators, such as static simulators, which do not actively move or change their state and can be cardboard targets, steel plate targets, humanoid targets, etc. Static simulators are mainly used to test the aiming and firing accuracy of guided bullets; dynamic simulators, through simulator control, can achieve movements such as up, down, left, right, tilting, and rotating. Dynamic simulators can test the ability of guided bullets to track and fire at moving targets; multiple simulators refer to placing multiple simulated targets in the same scenario, and testing when multiple targets appear simultaneously. Guided bullets need to quickly locate, aim, and fire targets using target recognition algorithms to improve their responsiveness and reaction speed. Targets can be combined and adjusted according to development needs, providing customized solutions.

[0003] Target simulators play a crucial role in hardware-in-the-loop (HIL) simulation systems, but traditional target detection methods often require complex hardware support and high-cost maintenance, failing to meet practical needs. Existing technologies cover all aspects of HIL simulation systems, but none have proposed an effective detection method or device specifically for target simulators. Summary of the Invention

[0013] like Figure 1 As shown, this invention proposes a target position detection device based on a hardware-in-the-loop simulation system. A CCD camera is mounted on the hardware-in-the-loop system in a direction relative to the target simulator; this allows all the movement positions of the target simulator to be within the imaging field of view of the CCD. The simulation computer acquires and receives image data from the CCD camera, processes the images using image processing software, extracts the location information of the target area, and feeds it back to the control terminal of the hardware-in-the-loop simulation system. A hardware-in-the-loop simulation system is used to simulate and verify the function of guided bullets. By adjusting and detecting the position of the target simulator, the guidance accuracy of the guided bullets is verified. The laser illuminator, target simulator, and guided bullet of the hardware-in-the-loop simulation system are all placed on a two-axis turntable, which can perform pitch and yaw attitude modulation.

[0014] The simulation computer is connected to a laser illuminator, a target simulator, a guided bullet, a dual-axis turntable, and a CCD camera, which are used for: Set the pulse width, repetition rate, and laser power of the laser; The target simulator's movement position; Receive guidance commands from guided bullets; The control turntable is used to adjust its position, process the CCD image, and identify the target position.

[0015] The device of this invention uses a CCD camera because CCD cameras have advantages such as high-quality images, fast imaging speed, low noise, low power consumption, and suitability for scientific experiments.

[0016] 1. High-quality images: CCD sensors can capture more light and provide higher-quality images, especially in low-light environments. CCD cameras generally produce better image quality than CMOS cameras.

[0018] 3. Less noise: CCD cameras have lower electronic noise than CMOS cameras, resulting in clearer and more accurate images.

[0019] 4. Low power consumption: CCD cameras consume less power than CMOS cameras when used in low light conditions, which means they have longer battery life and less heat generation.

[0020] 5. Suitable for scientific experiments: Due to the accuracy and stability of CCD cameras, they are frequently used in scientific experiments and measurements, such as in fields like astronomy and biology.

Implement on / off control of the target recognition function according to actual needs; 3. Imaging area: This mainly uses a CCD camera to display the entire target simulator within the camera's field of view, and uses image processing algorithms to calculate the specific position information of the target simulator. 4. Based on requirements, realize the digital printing of the target identification position, so as to facilitate comparison with the target position information obtained by the guided bullet through the guidance law and verify the accuracy of the guidance law.

[0022] This invention relates to a target position detection method based on a hardware-in-the-loop simulation system, comprising: Step 1: Mount the CCD camera on the hardware-in-the-loop system in a direction opposite to the target simulator to ensure that real-time images of the target simulator can be captured. Step 2: Acquire image data from the CCD camera and transmit it to the simulation computer; Step 3: Use image processing software to process the image and extract the location information of the target area; Step 4: Feed back the extracted location information to the control terminal of the hardware-in-the-loop simulation system; Step 5: When simulating and verifying the guided bullet function, the guidance accuracy of the guided bullet is verified by adjusting and detecting the target simulator position.

[0023] This invention employs a high-definition CCD camera for imaging, and obtains clear and stable image data by adjusting parameters such as focal length and imaging brightness. Simultaneously, this invention utilizes efficient image processing algorithms to optimize the extraction and detection process of the target region, ensuring the accuracy and stability of the location information.
