Description

Technical Field

[0001] The utility model relates to the technology of unmanned aerial vehicles, in particular to an unmanned aerial vehicle device for continuously collecting multi-angle remote sensing images. Background Art

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are fully or intermittently autonomously operated by onboard computers. With the development of UAV technology and hyperspectral imaging technology, UAV-based hyperspectral remote sensing has become an important tool in the fields of environmental monitoring and agricultural remote sensing.

[0003] Traditional drone imaging devices are usually installed on drones at fixed angles, which means that data can only be collected from one or a few fixed angles during imaging. This leads to incomplete ground target information, especially for targets with complex three-dimensional structures, where a single perspective cannot fully capture their full picture. Moreover, using a single perspective for target range recognition often leads to blurred boundaries, especially in areas with similar spectral features, making it difficult to accurately distinguish different types of ground objects, affecting the accuracy of subsequent analysis. It can only improve recognition accuracy by adding hyperspectral data from multiple independent perspectives, but this will greatly increase the cost of use. Therefore, it is necessary to further improve the existing drone structure. Utility Model Content

[0025] Please refer to Figures 1 to 4 As shown, it shows the specific structure of the preferred embodiment of the present utility model, which includes a drone 1, a fixed-angle imaging module 2, and a multi-angle imaging module 3.

[0026] The fixed-angle imaging module 2 is arranged on the drone 1 and is located at the bottom of the drone 1. The fixed-angle imaging module 2 includes a first mounting bracket 21 and a first lens 22. The first mounting bracket 21 is fixedly installed at the bottom of the drone 1. The first mounting bracket 21 has a first installation cavity 201 with one end open. The first lens 22 is arranged in the first installation cavity 201 and is directly opposite to the opening of the first installation cavity 201.

[0027] In this embodiment, there are two first lenses 22 arranged at intervals left and right, and the first lenses 22 are hyperspectral sensor lenses; both sides of the first mounting bracket 21 are provided with first air vents 202 communicating with the inside of the first mounting cavity 201, and a first fan 23 is arranged in each first air vent 202. During the flight of the drone, the airflow passes through the two first air vents 202 in sequence, thereby driving the two first fans 23 to rotate. The first fans 23 can ensure the flow of the gas inside the first mounting cavity 201, thereby enhancing the internal heat dissipation function. Two first baffles 24 and a second driving mechanism 25 are arranged in the first mounting cavity 201. The two first baffles 24 are movably arranged beside the inner sides of the corresponding first air vents 202. The second driving mechanism 25 is arranged on the first mounting bracket 21 and drives the two first baffles 24 to move back and forth. In a harsh environment, the first air vents 202 can be closed by the first baffles 24, thereby preventing external dust and foreign objects from entering the interior, effectively protecting the internal structure of the fixed-angle imaging module 2; a first wind plate 26 is arranged on the inner side of each first air vent 202, and a plurality of first inclined holes 203 corresponding to the first air vents 202 are penetrated through the first wind plate 26.

The first heat dissipation plate 27 is located on the back of the first lens 22 and is attached to the inner side wall of the first mounting cavity 201. The first heat dissipation plate 27 is used to increase the heat dissipation speed of the heat generated by the first lens 22 during operation, avoiding heat accumulation and damaging the overall structure. A first heat dissipation hole 204 communicating with the first mounting cavity 201 is arranged on the side wall of the first mounting bracket 21. The first heat dissipation holes 204 are multiple and arranged at intervals. A first filter screen 28 is arranged in each first heat dissipation hole 204.

[0029] The multi-angle imaging module 3 is arranged on the top of the drone 1. The multi-angle imaging module 3 includes a second mounting bracket 31, a rotating seat 32, a first driving mechanism 33 and a second lens 34; the second mounting bracket 31 is arranged on the top of the drone 1, and the second mounting bracket 31 has a second mounting cavity 301 with one end open. The rotating seat 32 is rotatably arranged in the second mounting cavity 301; the first driving mechanism 33 is arranged in the second mounting cavity 301 and drives the rotating seat 32 to rotate back and forth. The second lens 34 is arranged on the rotating seat 32 and rotates back and forth with the rotating seat 32, thereby realizing the multi-angle imaging process. The second lens 34 faces the opening of the second mounting cavity 301.

[0030] In this embodiment, there are two second lenses 34 arranged at intervals left and right, and the second lens 34 is a hyperspectral sensor lens; in other embodiments, the number of the first lens 22 and the second lens 34 can also be multiple set according to actual situations. Both sides of the second mounting bracket 31 are provided with second air vents 302 communicating with the inside of the second mounting cavity 301, and each second air vent 302 is provided with a second fan 35. During the flight of the drone, the air flow passes through the two second air vents 302 in sequence, thereby driving the two second fans 35 to rotate. The second fan 35 can ensure the flow of the gas inside the second mounting cavity 301, thereby enhancing the internal heat dissipation function; two second baffles 36 and a third driving mechanism 37 are arranged inside the second mounting cavity 301. The two second baffles 36 are movably arranged beside the inner sides of the corresponding second air vents 302, and the third driving mechanism 37 is arranged on the second mounting bracket 31 and drives the two second baffles 36 to move back and forth; in a harsh environment, the second air vents 302 can be closed by the second baffles 36, thereby preventing external dust and foreign objects from entering the inside, effectively protecting the internal structure of the multi-angle imaging module 3; a second air plate 38 is arranged inside each second air vent 302, and a plurality of second inclined holes 303 corresponding to the second air vents 302 penetrate through the second air plate 38. The second inclined holes 303 are used to effectively reduce the noise and excessive impact generated when the air flow enters the multi-angle imaging module 3. A second heat dissipation plate 39 is arranged inside the second mounting cavity 301. The second heat dissipation plate 39 is located on the back of the second lens 34 and is attached to the inner side wall of the second mounting cavity 301. The second heat dissipation plate 39 is used to increase the heat dissipation speed of the second lens 34 when it is working, and avoid damage to the overall structure due to heat accumulation. A second heat dissipation hole 304 communicating with the second mounting cavity 301 is arranged on the side wall of the second mounting bracket 31. The second heat dissipation holes 304 are multiple and arranged at intervals. A second filter screen 311 is arranged in each second heat dissipation hole 304. The second filter screen 311 is used to prevent external dust from entering the multi-angle imaging module 3. Both the first heat dissipation plate 27 and the second heat dissipation plate 39 are graphene heat dissipation fins.

[0031] A first transmission gear 321 is arranged on the rotating seat 32, and a second transmission gear 331 meshing with the first transmission gear 321 is arranged at the output end of the first driving mechanism 33. The first driving mechanism 33 drives the rotating seat 32 to rotate through the cooperation of the second transmission gear 331 and the first transmission gear 321, thereby driving the second lens 34 to perform multi-angle rotation. The second mounting bracket 31 is connected to the drone 1 through a push rod 312. The push rod 312 is telescopically arranged. A fourth driving mechanism 313 is arranged on the drone 1 and drives the push rod 312 to expand and contract. When the multi-angle imaging module 3 does not need to take pictures, the multi-angle imaging module 3 can be retracted into the drone 1 through the push rod 312, thereby reducing the wind resistance during the flight of the drone 1 and ensuring the stability of the flight process of the drone 1.

[0032] Furthermore, an anti-fog film is provided on the surfaces of the first lens 22 and the second lens 34. The anti-fog film is formed by spraying an AF material (perfluoropolyether) on its surface and then undergoing high-temperature curing to form an anti-fog coating, thereby preventing the surfaces of the first lens 22 and the second lens 34 from fogging during operation and affecting the imaging effect.

[0033] The working principle of this embodiment is described in detail as follows:

[0034] When the drone 1 takes off and executes a mission, the fixed-angle imaging module at the bottom is immediately activated to quickly scan a large area of the target area and collect macroscopic environmental data, providing a preliminary positioning for subsequent refined analysis. When the drone approaches a specific target, the multi-angle imaging module at the top automatically extends through the lifting push rod 312 to perform continuous imaging from different perspectives, and high-resolution multi-angle image data can be obtained.

[0035] The design focus of the present utility model lies in: through the fixed-angle imaging module and the multi-angle imaging module, and the multi-angle imaging module includes a second mounting bracket, a rotating base, a first driving mechanism, and a second lens; and the second lens is arranged on the rotating base and rotates back and forth with the rotating base, so that when imaging, it can first perform a quick large-area scan of the target area through the fixed-angle imaging module, and then through the conversion of the second lens in the multi-angle imaging module, continuous imaging can be performed from different perspectives, making the ground information more complete, thereby avoiding the situation where the recognition boundary of the target range is blurred. Especially in areas with similar spectral characteristics, it is difficult to accurately distinguish different types of ground objects, ensuring the accuracy of subsequent analysis, and there is no need for multiple fixed-angle lenses, effectively reducing the overall usage cost.

[0036] The above description is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change, and modification made to the above embodiment based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
