Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) target recognition and tracking technology, and in particular to a target orientation device for UAVs. Background Technology

[0002] With the rapid development of UAV technology, its application in target recognition, tracking, inspection and reconnaissance-strike integration is becoming increasingly widespread. Target locking and tracking are the foundation and core of achieving the above-mentioned advanced tasks. At present, mainstream target tracking technology usually consists of photoelectric sensors, image processing units and navigation and positioning systems. Its working principle is mostly based on registering and fusing the acquired target visual information with spatiotemporal references to achieve continuous guidance and locking of the target.

[0003] During the tracking of UAV targets by ground-based orientation equipment, the target plate needs to receive photoelectric signals to achieve accurate positioning. However, in strong outdoor light environments, stray light in the environment will form a high-brightness glare reflection layer on the target plate surface. This reflection layer will interfere with the target plate's reception and analysis of effective photoelectric signals, resulting in a reduced signal-to-noise ratio, difficulty in extracting target features, and ultimately affecting the stability and accuracy of the tracking system.

[0004] Therefore, to address the above issues, a target orientation device for UAVs can be designed. By deploying a light-blocking structure around the target, the influence of stray light from the external environment on the photoelectric signal received by the target can be effectively reduced. Utility Model Content

[0005] In order to overcome the problem that stray light in the outdoor environment will form a high-brightness glare reflection layer on the target plate surface, which will interfere with the target plate's reception and interpretation of effective photoelectric signals, resulting in a reduced signal-to-noise ratio, difficulty in target feature extraction, and ultimately affecting the stability and accuracy of the tracking system.

[0006] The technical solution of this utility model is as follows: a target orientation device for unmanned aerial vehicles, including an outer shell and a target, the target being fixedly installed on the upper end of the outer shell by fasteners, and a control motherboard disposed inside the outer shell. The outer shell is provided with a fixing mechanism for positioning and assembling the control motherboard, and a light-blocking mechanism is disposed on the outer periphery of the outer shell, the light-blocking mechanism being located on the periphery of the target.

[0007] Preferably, the control motherboard is stably positioned and mounted inside the outer casing by a fixing mechanism. The target receives the photoelectric signals emitted by the UAV and transmits them to the control motherboard. The control motherboard integrates a photoelectric processing module, a guidance module, and a positioning transmission module. Its working principle is based on spatiotemporal registration technology. First, the positioning transmission module obtains the precise spatial location information and time series data of the target. Then, this information is dynamically matched and fused with the target visual features processed by the photoelectric processing module. On this basis, the guidance module continuously tracks the target and locks the key feature points of the target in real time, ensuring high stability and high-precision tracking capability of the target even in complex environments. The light-blocking mechanism can effectively reduce the impact of stray light in the external environment on the photoelectric signals received by the target.

[0008] Preferably, the light-blocking mechanism includes a light-blocking plate that is fixedly mounted to the rear side of the housing by fasteners.

[0009] Preferably, the fixing mechanism includes several blocks fixedly installed inside the housing, and each block has mounting holes on its surface.

[0010] Preferably, the light-blocking mechanism includes a mounting bracket that is fixedly installed on the periphery of the housing by fasteners. A connector is slidably connected to the upper end of the mounting bracket, and a light-blocking plate is fixedly installed on the upper end of the connector. The connector has a circular structure and is interference-fitted with the mounting bracket.

[0011] Preferably, the fixing mechanism includes several brackets fixedly installed inside the housing, each bracket having mounting holes on its surface, and several plugs corresponding to the mounting holes fixedly installed on the rear side of the control board.

[0012] Preferably, each set of blocks is rotatably connected to a pressure plate at its upper end, and the lower end of the pressure plate is set on an anti-slip pad, with the lower surface of the anti-slip pad in interference contact with the upper surface of the control main board.

[0013] Preferably, the outer periphery of the housing has several wire holes of different sizes, and a front cover plate is fixedly installed on the front side of the housing by fasteners.

[0014] Preferably, a mounting flange is fixedly installed at the lower end of the outer casing, and an internal threaded sleeve is fixedly installed at the lower end of the mounting flange.

[0015] The beneficial effects of this utility model are:

[0016] 1. The mounting bracket and connectors are used to enable the movable assembly of the light-blocking plate on the periphery of the target. The interference fit between the connectors and the mounting brackets ensures the stability of the light-blocking plate in the non-adjustable state. This allows the light-blocking plate to dynamically adjust its position and blocking orientation according to the external lighting environment, thereby effectively reducing the interference of stray light from the outside. This significantly enhances the anti-interference capability and dynamic stability of the target tracking system, ensuring that it can maintain high-precision and high-reliability target locking and tracking performance even in complex lighting environments.

[0017] 2. The control board can be quickly positioned on the upper part of the support block by the cooperation of the plug rod and the mounting hole. Then, the pressure plate rotates on the upper part of the support block to move it above the control board, so that the anti-slip pad is in close contact with the control board. The pressure plate is fixed by friction, thereby realizing the installation and locking of the control board. Quick maintenance can be achieved without the use of tools. Attached Figure Description

[0029] Please see Figure 1 and Figure 3 This utility model provides an embodiment: a target orientation device for a drone, including a housing 1 and a target 2. The target 2 is fixedly installed on the upper end of the housing 1 by fasteners. It also includes a control motherboard 6 disposed inside the housing 1. A fixing mechanism for positioning and assembling the control motherboard 6 is provided inside the housing 1, and a light-blocking mechanism is provided on the periphery of the housing 1, located around the target 2. The fixing mechanism stably positions and assembles the control motherboard 6 inside the housing 1. The target 2 receives photoelectric signals emitted by the drone and transmits them to the control motherboard 6. The control motherboard 6 integrates… It has an optoelectronic processing module, a guidance module, and a positioning and transmission module. Its working principle is based on spatiotemporal registration technology. First, the positioning and transmission module obtains the precise spatial location information and time series data of the target. Then, this information is dynamically matched and fused with the target visual features processed by the optoelectronic processing module. On this basis, the guidance module continuously tracks the target and locks the key feature points of the target in real time, ensuring that it can maintain high stability and high precision tracking capability of the target even in complex environments. The light-blocking mechanism can effectively reduce the impact of stray light in the external environment on the optoelectronic signal received by the target 2.

[0030] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the light-blocking mechanism includes a light-blocking plate 301 fixedly installed on the rear side of the outer casing 1 by fasteners; the light-blocking plate 301 can reduce the influence of external stray light on the target 2; the fixing mechanism includes a plurality of support blocks 7 fixedly installed inside the outer casing 1, and each set of support blocks 7 has mounting holes 701 on its surface; the support blocks 7 support and install the control main board 6, and the mounting holes 701, together with the fasteners, can realize the positioning and fixing of the control main board 6; the outer casing 1 has a plurality of wire-passing holes 101 of different specifications on its periphery, and the front cover plate 5 is fixedly installed on the front side of the outer casing 1 by fasteners; by reasonably planning the wire-passing holes 101, the control main board 6 can be fixedly installed on the target 2; the control main board 6 can be fixedly installed on the target 2 by fasteners ... The cable hole 101 position meets the wiring requirements of different application scenarios, while optimizing the internal cable routing path, reducing signal crosstalk and improving the electromagnetic compatibility of the equipment. The front cover 5 can effectively block external dust, moisture and other contaminants from entering the equipment. At the same time, the fastener installation method facilitates the later maintenance of the outer shell 1. The lower end of the outer shell 1 is fixedly installed with a mounting flange 4, and the lower end of the mounting flange 4 is fixedly installed with an internal threaded sleeve 401. The internal threaded sleeve 401 provides a standardized interface that can be adapted to various mounting brackets, improving the versatility and installation adaptability of the equipment, and the mounting flange 4 achieves a stable fixation.

[0031] Example 2

[0032] Please see Figure 4 and Figure 5 The difference from Embodiment 1 is that, in this embodiment, the light-blocking mechanism includes a mounting bracket 302 fixedly installed on the periphery of the outer casing 1 by fasteners. A connector 303 is slidably connected to the upper end of the mounting bracket 302, and a light-blocking plate 301 is fixedly installed on the upper end of the connector 303. The connector 303 has a circular structure and is interference-fitted with the mounting bracket 302. The mounting bracket 302 and the connector 303 enable the movable assembly of the light-blocking plate 301 on the periphery of the target 2. The interference fit between the connector 303 and the mounting bracket 302 ensures the stability of the light-blocking plate 301 in the non-adjusted state, so that the light-blocking plate 301 can dynamically adjust its position and blocking direction according to the external lighting environment, thereby effectively reducing the interference of stray light from the outside and improving its applicability.

[0033] Please see Figure 6 , Figure 7 and Figure 8The difference from Embodiment 1 is that, in this embodiment, the fixing mechanism includes several support blocks 7 fixedly installed inside the outer casing 1. Each set of support blocks 7 has mounting holes 701 on its surface. Several insertion rods 601 corresponding to the mounting holes 701 are fixedly installed on the rear side of the control main board 6. Each set of support blocks 7 has a pressure plate 702 rotatably connected to its upper end. The lower end of the pressure plate 702 is set on an anti-slip pad 703. The lower surface of the anti-slip pad 703 is in interference contact with the upper surface of the control main board 6. The cooperation between the insertion rods 601 and the mounting holes 701 can realize the quick positioning of the control main board 6 on the upper end of the support block 7. Then, by rotating the pressure plate 702 on the upper end of the support block 7, it is moved to the top of the control main board 6, so that the anti-slip pad 703 is in close contact with the control main board 6. The pressure plate 702 is fixed by friction, thereby realizing the installation and locking of the control main board 6. Compared with fasteners, this is more convenient and faster, and quick maintenance can be achieved without the use of tools.

[0034] Through the above steps, the target 2 receives the photoelectric signal emitted by the UAV and transmits it to the control motherboard 6 for processing. The control motherboard 6 is stably positioned and assembled inside the outer shell 1 by the fixing mechanism. The light blocking mechanism can effectively reduce the influence of stray light in the external environment on the photoelectric signal received by the target 2, significantly enhancing the anti-interference capability and dynamic stability of the target tracking system, and ensuring that high-precision and high-reliability target locking and tracking performance can still be maintained in complex lighting environments. This solves the problem that in strong outdoor light environments, stray light in the environment will form a high-brightness glare reflection layer on the target plate surface. This reflection layer will interfere with the target plate's reception and analysis of effective photoelectric signals, resulting in a reduced signal-to-noise ratio, difficulty in target feature extraction, and ultimately affecting the stability and accuracy of the tracking system.
