Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and more specifically, to an unmanned aerial vehicle landing platform and system. Background Art

[0002] An unmanned aerial vehicle is an unpiloted aircraft that is controlled by a radio remote control device and a self - contained process control device, and has the advantages of small size, low cost, and convenient use. With the rapid development of unmanned aerial vehicle technology, unmanned aerial vehicles are increasingly widely used in fields such as agricultural plant protection, power line inspection, aerial photography and mapping, express delivery logistics, and security monitoring. Unmanned aerial vehicles have become an essential key tool in many industries.

[0003] When the unmanned aerial vehicle returns after performing a mission, it usually relies on the GPS positioning system to automatically guide the return flight, and then the unmanned aerial vehicle is landed by manual control or visual automatic guidance. During the process of manual control, the accuracy of the unmanned aerial vehicle landing is significantly affected by the skill level of the operator. Even a slight change in the operator's inexperience or movement amplitude may cause the unmanned aerial vehicle to roll over or tip over, thereby causing damage to the unmanned aerial vehicle and its related equipment. During the process of visually automatically guiding the unmanned aerial vehicle to land, it is extremely vulnerable to environmental influences, resulting in difficult precise landing.

[0050] Please refer to Figure 1 and Figure 2 , this embodiment provides a drone landing platform 100, which includes a platform board 1, a light-emitting board 2, a transparent sticker 3, and a brightness regulator 4.

[0051] The light-emitting board 2 is arranged on the platform board 1, and the transparent sticker 3 is arranged on the surface of the light-emitting board 2 away from the platform board 1.

[0052] The light-emitting board 2 includes a control line 21, and the control line 21 is connected to the output end of the brightness regulator 4.

[0053] A guiding code 5 is arranged on the transparent sticker 3.

[0054] The brightness regulator 4 is used to output a brightness adjustment signal to the light-emitting board 2.

[0055] Among them, the shapes of the platform board 1, the light-emitting board 2, and the transparent sticker 3 can be the same. Moreover, the platform board 1, the light-emitting board 2, and the transparent sticker 3 can be regular shapes, such as, it can be a rectangle, or a circle, or an ellipse, etc. The platform board 1, the light-emitting board 2, and the transparent sticker 3 can also be irregular shapes, such as the shape shown in the figure. Here, the shapes of the platform board 1, the light-emitting board 2, and the transparent sticker 3 are not limited.

[0056] Here, for the convenience of maintenance and replacement, the platform board 1 and the light-emitting board 2 can be adhesively connected, threadedly connected, key-connected, hook-groove connected, snap-connected or any other detachable connection method, and the transparent sticker 3 is adhesively connected to the light-emitting board 2.

[0057] Through the structure of the above-mentioned drone landing platform 100, in an environment where it is difficult for the drone camera to obtain a clear image of the guiding code 5 in insufficient light, at night, etc., the brightness of the light-emitting board 2 can be dynamically adjusted by the brightness regulator 4 so that the guiding code 5 remains in the best visible state, ensuring that the guiding code 5 on the platform can always be clearly captured by the drone camera, thereby helping to improve the reliability and accuracy of drone landing. At the same time, by using the uniform light emission of the light-emitting board 2, each part of the transparent sticker 3 exhibits a consistent brightness level, reducing the shadows and contrast differences that may be caused by uneven illumination, and significantly improving the image clarity and recognition accuracy of the drone, providing more reliable support for the landing of the drone in various lighting environments.

[0058] In order to quickly and accurately adjust the brightness of the drone landing platform 100 to the required brightness at which the drone camera can capture and recognize the identification code, a function is added to the drone landing platform 100: automatically adjusting the platform brightness according to the image capture and recognition situation of the drone camera to ensure that the identification code is always within the best brightness range recognizable by the camera.

[0059] To implement the above function, referring to Figure 3 , the brightness controller 62 may further include a communication module 41, and the communication module 41 is used for communication connection with the controller 62 of the drone 6.

[0060] The brightness regulator 4 is used to output a brightness adjustment signal to the light-emitting board 2 in response to the recognition information received by the communication module 41. Among them, the recognition information is the recognition result of the image captured by the camera 61 of the drone 6 by the controller 62.

[0061] After the drone 6 returns to the preset landing site and enters the landing mode, it controls the camera 61 lens to face the ground, and captures images in real time through the camera 61, and recognizes the current image to obtain recognition information. The recognition of the image may include the recognition of the identification code, and may also include brightness recognition, etc., which is not limited in this embodiment.

[0062] When the identification code on the UAV landing platform 100 is at a brightness level recognizable by the camera 61, the identification information includes the identification ID corresponding to at least one identification code on the UAV landing platform 100. When the identification code on the UAV landing platform 100 is not at a brightness level recognizable by the camera 61 (i.e., insufficient brightness), there is no identification ID in the identification information, or it includes an error code and a brightness adjustment value, or only includes an error code. At this time, the flight control device packs the identification information into an adjustment instruction and sends the adjustment instruction to the brightness regulator 4. Thus, after receiving the adjustment instruction, the brightness regulator 4 gradually increases the brightness of the light-emitting panel 2 by outputting a brightness adjustment signal to the light-emitting panel 2, or adjusts the brightness of the light-emitting panel 2 by outputting a brightness adjustment signal to the light-emitting panel 2 according to the brightness adjustment value in the identification information until the flight control device no longer issues an adjustment instruction.

[0063] In addition, in the UAV landing platform 100 provided in this embodiment, the brightness of the light-emitting panel 2 can also be adjusted according to the ambient brightness. At this time, the UAV landing platform 100 further includes a brightness sensor, and the output end of the brightness sensor is connected to the input end of the brightness regulator 4.

[0064] The brightness regulator 4 is configured to output a brightness adjustment signal to the light-emitting panel 2 in response to the detection value of the brightness sensor.

[0065] In addition, an adjustment instruction and an adjustment amount can also be manually input to the brightness regulator 4 to output a brightness adjustment signal to the light-emitting panel 2 through the brightness regulator 4.

[0066] It should be noted that the above methods of adjusting brightness are only examples, and their implementation methods are not limited.

[0067] In order to be able to guide the UAV 6 to land on the UAV landing platform 100 in an expected pose to adapt to landing platforms of different sizes. Refer to Figure 4 , the UAV landing platform 100 includes a landing area 11. There are multiple guiding codes 5, and the area of the guiding code 5 is proportional to the landing area distance of the guiding code 5. Among them, the landing area distance is the distance between the guiding code 5 and the landing area 11.

[0068] On this basis, a priority can be set for each guiding code 5. The priority refers to the guiding priority. When the flight control device recognizes multiple guiding codes 5, the guiding code 5 with the highest priority is selected for descending pose adjustment.

[0069] Thus, the area of the identification code closer to the landing area 11 is smaller, so that during the process of the UAV 6 landing close to the landing platform, the complete identification code always exists in the image captured by the camera 61, and the UAV descends according to the guidance based on this, improving the reliability of landing. At the same time, the closer the identification code is to the landing area 11, the higher its priority (i.e., the guidance priority), so that the UAV 6 can finally land accurately in the expected pose (i.e., the pose guided by the identification code in the landing area 11), which helps to further improve the landing accuracy of the UAV 6.

[0070] In order to accurately guide the UAV 6 to land on the landing platform in the expected pose and avoid increasing the landing complexity due to too many identification codes. Please continue to refer to Figure 4 , the guidance code 5 includes a first-level two-dimensional code 51, a second-level two-dimensional code 52, a third-level two-dimensional code 53 and a fourth-level two-dimensional code 54 with gradually increasing areas.

[0071] The first-level two-dimensional code 51 is located in the landing area 11.

[0072] There are at least two second-level two-dimensional codes 52, third-level two-dimensional codes 53 and fourth-level two-dimensional codes 54.

[0073] The first third-level two-dimensional code 53 is located in the area close to the landing area 11, and the second third-level two-dimensional code 53 is located on one side of the first third-level two-dimensional code 53 and far from the first-level two-dimensional code 51.

[0074] Two second-level two-dimensional codes 52 are located on both sides of the first third-level two-dimensional code 53.

[0075] Two fourth-level two-dimensional codes 54 are located on both sides of the second third-level two-dimensional code 53.

[0076] Based on the above settings, under normal circumstances, during the descent of the UAV 6, the pose is first adjusted according to the fourth-level two-dimensional code 54 and then descends. When descending to a certain height, the third-level two-dimensional code 53 starts to be recognized, the pose is adjusted according to the third-level two-dimensional code 53 and continues to descend. After descending a certain distance, the second-level two-dimensional code 52 starts to be recognized, the pose is adjusted according to the second-level two-dimensional code 52, and finally, after the pose is adjusted according to the first-level two-dimensional code 51 recognized last, the UAV will land on the UAV landing platform 100 with the camera 61 facing the landing area 11.

[0077] At the same time, there are at least two second-level two-dimensional codes 52, third-level two-dimensional codes 53 and fourth-level two-dimensional codes 54, so that when other two-dimensional codes with the same priority are blocked or cut by the shadow, the UAV 6 can adjust the descent pose according to another two-dimensional code. In this way, it can not only accurately guide the UAV 6 to land on the landing platform in the expected pose, but also avoid increasing the landing complexity due to too many identification codes.

[0078] To enable the drone 6 to land on the landing platform in the expected pose, facilitating the subsequent retrieval of the drone 6 by the nest and further improving the landing accuracy. Please continue to refer to Figure 4 The landing area 11 includes a main area and a secondary area, and the main area is located at the center of the landing area 11. There are at least three first-level two-dimensional codes 51, one first-level two-dimensional code 51 is located in the main area, and the remaining two first-level two-dimensional codes 51 are located in the secondary areas and on both sides of the main area.

[0079] Thus, when the recognized guiding code 5 includes the first-level two-dimensional code 51 in the main area, the drone 6 is controlled to horizontally move in the direction close to the first-level two-dimensional code 51 in the main area, and after the horizontal movement ends, the drone 6 is controlled to land. When the recognized guiding code 5 only includes the first-level two-dimensional code 51 in the secondary area, the drone 6 is controlled to horizontally move in the direction close to any first-level two-dimensional code 51 in the secondary area, and after the horizontal movement ends, the drone 6 is controlled to land.

[0080] In this way, it lands in the expected pose as much as possible, improving the landing accuracy.

[0081] To enable the light-emitting panel 2 to work for a long time, the drone landing platform 100 may further include a battery module, and the output end of the battery module is connected to the power input end of the light-emitting panel 2.

[0082] Here, the battery module can be a power supply module composed of solar cells, or a power supply module composed of rechargeable batteries such as lithium batteries, or a power supply module composed of a parallel connection of solar cells and lithium batteries. And the above are only examples, and the implementation method of the battery module is not limited.

[0083] To reduce the cost of the drone landing platform 100 and improve safety, the light-emitting panel 2 may include a power cord for connecting to a power socket. In this way, the battery is omitted, the cost is reduced, and the safety can also be improved.

[0084] Based on the above drone landing platform 100, after the drone 6 returns to the landing site, the camera 61 is controlled to take an image, and in the case where at least one guiding code 5 cannot be normally recognized in the image, identification information is sent to the brightness adjuster 4 to instruct the brightness adjuster 4 to adjust the brightness of the drone landing platform 100. When it is adjusted to a state where the guiding code 5 can be recognized, the drone 6 starts to descend.

[0085] At the beginning of the descent, when the altitude of the drone 6 is relatively high, through the vision of the camera 61, the drone 6 will first recognize two four-level two-dimensional codes 54. If one of the codes is blocked or cut by a shadow, the vision of the camera 61 makes a judgment and feeds the judged information back to the flight control device, and the flight control device adjusts the position of the drone 6 to directly above the four-level two-dimensional code 54 that is not blocked or cut by a shadow. If it is not blocked or cut by a shadow, one of the four-level two-dimensional codes 54 is selected to adjust the pose. After adjusting the pose, the drone 6 continues to descend.

[0086] When continuing to descend to a medium altitude, the vision of the drone 6 will recognize two three-level two-dimensional codes 53 (with an area second only to the four-level two-dimensional code 54). If both three-level two-dimensional codes 53 are blocked or cut by a shadow, the flight control device continues to descend until two second-level two-dimensional codes 52 (with an area smaller than the three-level two-dimensional code 53) are recognized, and then adjusts the pose according to the recognized two-dimensional code and continues to descend. If the three-level two-dimensional code 53 is not blocked or cut by a shadow, the flight control device selects one to adjust the pose and controls the drone 6 to continue descending.

[0087] When the drone 6 descends close to the landing platform, the drone 6 will recognize three first-level two-dimensional codes 51. Normally, the vision of the drone 6 will adjust the landing pose with the middle first-level two-dimensional code 51 (i.e., the first-level two-dimensional code 51 in the main area), and then land on the platform. When the middle first-level two-dimensional code 51 is blocked or cut by a shadow, the drone 6 will adjust to above any one of the first-level two-dimensional codes 51 on both sides (i.e., the sub-areas), and then continue to descend until it lands on the landing platform.

[0088] Based on the same concept as the above-mentioned drone landing platform 100, an embodiment of the present invention also provides a machine nest, including a machine nest body and the drone landing platform 100 provided above.

[0089] Based on the same concept, an embodiment of the present invention also provides a drone landing system, including a drone 6 and a machine nest. The machine nest includes a drone landing platform 100, and the drone landing platform 100 includes a platform board 1, a light-emitting board 2, a transparent sticker 3, and a brightness adjuster 4.

[0090] The light-emitting board 2 is arranged on the platform board 1, and the transparent sticker 3 is arranged on the surface of the light-emitting board 2 away from the platform board 1.

[0091] The light-emitting board 2 includes a control line 21, and the control line 21 is connected to the output end of the brightness adjuster 4.

[0092] The transparent sticker 3 is provided with a guiding code 5.

[0093] The brightness adjuster 4 is used to output a brightness adjustment signal to the light-emitting board 2.

[0094] Further, the drone 6 includes a controller 62 and a camera 61, and the brightness adjuster 4 includes a communication module 41. The controller 62 is communicatively connected to the camera 61 and the communication module 41 respectively.

[0095] The controller 62 is configured to send the recognition result of the image captured by the camera 61 to the communication module 41.

[0096] The brightness adjuster 4 is configured to output a brightness adjustment signal to the light-emitting panel 2 in response to the recognition information received by the communication module 41.

[0097] In the above drone landing system, in an environment where it is difficult for the drone camera to obtain a clear image of the guiding code 5, such as in insufficient light or at night, the brightness of the light-emitting panel 2 can be dynamically adjusted by the brightness adjuster 4, so that the guiding code 5 remains in the best visible state, ensuring that the guiding code 5 on the platform can always be clearly captured by the drone camera. Furthermore, the drone 6 can adjust its pose based on the scanning and recognition result of the guiding code 5 to accurately land on the landing area 11, greatly improving the landing accuracy.

[0098] Regarding the specific implementation and effects of the drone landing platform in the drone landing system, reference can be made to the description of the implementation of the drone landing platform in the above text, which will not be elaborated here.

[0099] In summary, the drone landing platform and system provided by the embodiments of the present invention have at least the following beneficial effects:

[0100] (1) Through the setting of the light-emitting panel, the brightness of the drone landing platform can be adjusted, so that the guiding code can remain in the best visible state whether in bright daytime or dim night, ensuring that the guiding code on the platform can always be clearly captured by the drone camera, which helps to improve the reliability and accuracy of drone landing;

[0101] (2) By connecting the brightness adjuster to the controller of the drone, the brightness adjuster can quickly and accurately adjust the brightness of the drone landing platform to the required brightness for the drone camera to capture and recognize the identification code according to the image scanning and recognition result of the drone camera;

[0102] (3) Utilizing the uniform light emission of the light-emitting panel, each part of the transparent sticker shows a consistent brightness level, reducing the shadows and contrast differences that may be caused by uneven illumination, and providing more reliable support for the drone to land in various lighting environments.
