Abstract
Description
Technical Field
[0001] This application relates to the field of photoelectric tracking and detection technology, specifically to a photoelectric guided tracking and detection method and system based on a tracking relay scenario. Background Technology
[0002] In recent years, with the rapid development of drone-related technologies, the application scenarios have become increasingly widespread and complex. The characteristics of drones include low flight altitude, slow speed, small reflective area, and indistinct target characteristics, making drone tracking, detection, and identification a significant challenge.
[0003] Currently, the primary detection methods for small unmanned aerial vehicles (UAVs) both domestically and internationally rely on radio detection, supplemented by other methods such as photoelectric detection. Radio detection offers advantages over photoelectric detection, including longer detection range, wider search area, distance information, and all-weather operation. However, it lacks the ability to identify low-flying UAVs, and is particularly vulnerable to interference from sea birds and waves, especially in shipborne detection technology, easily missing targets with small reflective surfaces. Furthermore, in practical applications, considering overall cost, the detection accuracy and performance of radio equipment used for UAV detection and tracking are not very high. Therefore, photoelectric detection systems, with their strong detail resolution, intuitive image display, and immunity to electromagnetic interference, are more advantageous.
[0004] Optoelectronic devices offer high detection accuracy. Once a target drone is captured and tracked, combined with laser ranging technology, it can provide accurate target information such as azimuth, pitch, and distance. However, in shipboard applications, due to installation limitations, a single optoelectronic detection device typically has blind spots and cannot completely cover the 360° area of the ship platform. When a drone enters the blind spot of the detecting and tracking device, the target is easily lost. Therefore, multiple optoelectronic detection devices are generally distributed and installed at multiple locations such as the bow and stern of the ship platform, forming a network architecture to achieve relay guidance, detection, tracking, and identification of target drones within the 360° range of the shipboard platform.
[0005] For target drones with small cross-sectional areas, optoelectronic devices typically operate within a narrow field of view (below 1°) to achieve stable tracking and identification. Since these devices are distributed across different locations on the shipboard platform, and baselines exist between them, the platform's swaying can cause significant issues. If the azimuth and pitch guidance data from one optoelectronic device is used to guide the next device at a distance of less than 5km, the drone is highly likely to be outside the narrow field of view of the next device, resulting in target loss. Furthermore, without ranging capabilities, the optoelectronic devices cannot perform position calculations, making it impossible to determine the precise guidance position of the target drone relative to the relay tracking sensor. Summary of the Invention
[0006] This application provides a photoelectric guidance tracking and detection method and system based on a relay tracking scenario. It can solve the technical problems in the prior art where, during the relay guidance of a target UAV, it is highly likely that the UAV will not be within the small field of view of the next photoelectric detection device, resulting in the loss of the target UAV. Furthermore, when the photoelectric detection device does not have a ranging function, it is impossible to perform position conversion and calculate the precise guidance position of the target UAV relative to the photoelectric detection device of the relay tracking.
[0007] Firstly, this application provides a photoelectric guided tracking and detection method based on a tracking relay scenario, comprising the following steps: Establish a 360° unobstructed drone detection platform; Based on the constructed UAV detection platform, an UAV photoelectric collaborative detection guidance coordinate system was established, and the spatial positions of multiple photoelectric detection devices within the UAV detection platform were determined. Once a photoelectric detection device detects the target drone, it acquires observation information about the target drone. When the captured target drone is about to fly out of the sensor field of view of the photoelectric detection device, switch the photoelectric detection device to be taken over to the wide field of view mode to perform coarse guidance operation to extract multiple drones; Perform scalar triple product calculation on the extracted multiple drones to filter out the target drones; Perform relay detection operations on the selected target drones.
[0008] In conjunction with the first aspect, in one implementation, the step of constructing a 360° unobstructed drone detection platform specifically includes the following steps: Multiple photoelectric detection devices are distributed on the shipboard platform and connected by a high-speed fiber optic network to form a network architecture, creating a 360° unobstructed drone detection platform.

[0010] In conjunction with the first aspect, in one implementation, the step of performing scalar triple product calculation on the extracted multiple drones to filter out the target drone specifically includes the following steps: Based on the target UAV observation information, obtain the center detection line vector of the current photoelectric detection equipment; Based on the relative positions of the current photoelectric detection device and the photoelectric detection device to be relayed, obtain the line vector connecting the two photoelectric detection devices; Based on the position information of multiple targets under the large field-of-view mode of the photoelectric detection equipment to be relayed, obtain the multi-target detection vector; Perform triple product calculation on the obtained center detection vector, connection vector and multi-target detection vector, and obtain the triple product calculation result; Based on the obtained triple product calculation results, the target drones are selected.
[0011] In conjunction with the first aspect, in one implementation, the step of filtering out target drones based on the obtained triple product calculation results specifically includes the following steps: If the result of the triple product is not zero, then the center detection vector, the connection vector, and the multi-target detection vector are determined to be non-coplanar. If the triple product result is zero, it is determined that the center detection vector, the connection vector, and the multi-target detection vector are coplanar. Then, the i-th UAV currently being tracked by the photoelectric detection device to be relayed is selected as the target UAV currently being tracked by the photoelectric detection device. The target position of the i-th UAV is then selected and loaded as the fine guidance command of the photoelectric detection device to be relayed.
[0012] In conjunction with the first aspect, in one implementation, the observation information is azimuth and elevation angle values.
[0013] In conjunction with the first aspect, in one implementation, the step of performing relay detection of the selected target UAVs specifically includes the following steps: Switch the photoelectric detection device to be relayed to the small field-of-view mode, and perform fine guidance operation on the photoelectric detection device to be relayed until the target UAV is located at the center of the small field of view of the photoelectric detection device to be relayed.
[0014] Secondly, this application provides a photoelectric guided tracking and detection system based on a tracking relay scenario, comprising: The detection platform assembly module is used to assemble a 360° unobstructed UAV detection platform. The coordinate system establishment module is communicatively connected to the detection platform assembly module. It is used to establish a UAV photoelectric cooperative detection guidance coordinate system based on the assembled UAV detection platform and to determine the spatial positions of multiple photoelectric detection devices within the UAV detection platform. The target acquisition module is communicatively connected to the coordinate system establishment module and is used to acquire the target UAV observation information after a photoelectric detection device acquires the target UAV. The multi-target extraction module is communicatively connected to the target acquisition module. When the captured target UAV is about to fly out of the sensor field of view of the photoelectric detection device, the photoelectric detection device to be taken over is switched to the wide-view mode to perform coarse guidance operation to extract multiple UAVs. The target filtering module is communicatively connected to the multi-target extraction module and is used to perform scalar triple product calculation on the extracted multiple UAVs to filter out the target UAVs. The relay tracking and adjustment module is communicatively connected to the target screening module and performs relay detection operations on the screened target UAVs.
[0015] In conjunction with the second aspect, in one implementation, the target screening module includes: The first vector acquisition unit is used to acquire the center detection line vector of the current photoelectric detection device based on the acquired target UAV observation information; The second vector acquisition unit is used to acquire the line vector connecting the two photoelectric detection devices based on the relative positions of the current photoelectric detection device and the photoelectric detection device to be relayed.

Then, it switches to a narrow field-of-view mode to set fine guidance commands, ensuring accurate relay tracking guidance of the target UAV by the next photoelectric detection device. This improves the target acquisition and tracking capabilities of the photoelectric system and fully utilizes the high detection and recognition accuracy of photoelectric equipment. Even without ranging functionality, it achieves accurate guidance between photoelectric devices for UAVs with indistinct target characteristics, avoiding the impact of factors such as baseline distance and lack of target distance information on photoelectric tracking.

[0025] In one embodiment, step S1, the step of constructing a 360° unobstructed UAV detection platform, specifically includes the following steps: Please refer to Figure 2 Multiple photoelectric detection devices are distributed across a shipboard platform, such as at the bow, stern, and port and starboard sides. These devices are interconnected via a high-speed fiber optic network to form a network architecture, creating a 360° unobstructed drone detection platform. The photoelectric sensors of the detection devices are mounted on servo turntables, which control the azimuth and pitch angles of the devices. Upon detecting a target drone, the system captures, tracks, and identifies the drone, outputting its azimuth and pitch angle observation information.
[0026] In one embodiment, step S2, establishing a UAV photoelectric cooperative detection guidance coordinate system based on the assembled UAV detection platform and determining the spatial positions of multiple photoelectric detection devices within the UAV detection platform, specifically includes the following steps: Based on the constructed UAV detection platform, with one of the photoelectric detection devices as the origin of the coordinate system, denoted as P0(0,0,0), the geodetic coordinate system n is defined as follows: adopting the northeast-central celestial coordinate system, with the ship's position as the farthest point, the X-axis pointing due east, the Y-axis pointing due north, and the X, Y, and Z axes following the right-hand coordinate system rule.

[0037] Step S55: Based on the obtained triple product calculation results, select the target drone.
[0038] In one embodiment, step S55, the step of filtering out target drones based on the obtained triple product calculation results, specifically includes the following steps: Step S551: If the result of the triple product is not zero, then it is determined that the center detection vector, the connection vector, and the multi-target detection vector are not coplanar; Step S552: If the triple product result is zero, it is determined that the center detection vector, the connection vector, and the multi-target detection vector are coplanar.
