Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a light perception and adjustment device for an image recognition UAV. Background Technology
[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices. They have no cockpit but are equipped with autopilots, program control devices, and other equipment. Ground-based, shipboard, or mother-aircraft remote control stations track, locate, remotely control, telemetry, and transmit digital data to them using radar and other equipment. They can take off like ordinary aircraft under radio remote control or be launched into the air with a booster rocket, or be carried into the air by a mother aircraft for deployment. During recovery, they can land automatically in the same manner as ordinary aircraft, or be recovered remotely using parachutes or nets. They can be reused multiple times. They are widely used for aerial reconnaissance, surveillance, communication, anti-submarine warfare, and electronic jamming.
[0003] For example, Chinese utility model patent (CN212473902U) discloses a high-strength image recognition drone structure, which states: "This utility model is a high-strength image recognition drone structure. The drone adopts a novel connection and installation structure, which can withstand strong winds and is suitable for harsh environments. It is equipped with visual recognition components to facilitate image monitoring and reduce operator workload. It also features an onboard computer to enhance machine performance. A novel sponge foot structure facilitates landing of the drone in various locations. The arms use pin positioning to increase the drone's accuracy." It further states: "Based on the existing technical conditions of drones, there are still many shortcomings in terms of usability and convenience. Most drone equipment is not suitable for flying in harsh environments, with a maximum wind resistance of only three to four levels. It lacks the corresponding automatic image detection function, and its flight time is short, only about ten minutes. Its remote control and image transmission range is also short, failing to meet modern usage needs and causing great inconvenience."
[0004] In summary, it can be seen that the existing technology uses camera components to collect image data. However, this method has the following technical problems: when the camera component is collecting images, if the external sunlight is strong, the strong sunlight may interfere with the captured image and thus affect the quality of the image collection. Therefore, this application proposes an image recognition drone light perception and adjustment device to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content
[0005] Based on this, it is necessary to provide a light perception and adjustment device for image recognition drones to address the aforementioned technical problems. This device uses a light intensity sensor to detect the intensity of external light. When the sunlight is strong, a first motor drives a threaded rod to rotate, causing a moving frame to move under the constraint of a fixed rod. This, in turn, uses a polarizing filter to block the lens of the camera body, reducing glare caused by sunlight reflection and improving image clarity, thus facilitating drone control. When the light intensity sensor detects weak external light, the first motor drives the threaded rod to rotate in the opposite direction, retracting the moving frame and polarizing filter into the connecting housing. This removes the obstruction of the camera lens, ensuring that the image captured by the camera body is not affected by the polarizing filter when the external light intensity is relatively low, thereby maintaining clarity and improving the device's practicality.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0029] As described in the background art, when the camera component is capturing images, if the external sunlight is strong, the intense sunlight may interfere with the captured image and thus affect the quality of the captured image.
[0030] To address this technical problem, this invention provides an image recognition drone's light perception and adjustment device, which is applied to the tracking and positioning of surveying drones.
[0031] For details, please refer to Figures 1-4 The light perception and adjustment device for image recognition drones specifically includes:
[0032] The drone body 1 has a fixed shell 2 fixedly connected to its bottom. A rotating cover 3 is rotatably connected to the outer wall of the fixed shell 2. A fixed frame 4 is fixedly installed on the outer wall of the rotating cover 3. A rotating shaft 5 is rotatably connected to the inner wall of the fixed frame 4. A camera body 6 is fixedly installed on the outer wall of the rotating shaft 5. A shielding mechanism 7 is provided on the camera body 6. An adjustment mechanism 8 is provided on the fixed frame 4. A positioning module body 9 is fixedly installed on the outer wall of the rotating cover 3.
[0033] The blocking mechanism 7 includes a support shell 10, a connecting shell 11, a light intensity sensor 17, a driving component, and a blocking component. Two support shells 10 are fixedly connected to the outer wall of the camera body 6, and a connecting shell 11 is fixedly connected between the two support shells 10. A light intensity sensor 17 is fixedly installed on the outer wall of the connecting shell 11.
[0034] In this application, the drone body 1, the camera body 6, and the positioning module body 9 are identical in specific structure and working principle to the drone body, camera component, and GPS positioning module in the prior art mentioned in the background.
[0035] The image recognition drone light sensing and adjustment device provided by this utility model can detect the intensity of external light through a light intensity sensor 17. When the external sunlight is strong, the first motor 14 drives the threaded rod 13 to rotate, causing the moving frame 15 to move under the restriction of the fixed rod 12. Then, the polarizing mirror 16 blocks the lens of the camera body 6, thereby reducing glare caused by sunlight reflection and improving image clarity, making it easier for operators to control the drone. When the light intensity sensor 17 detects that the external light is weak, the first motor 14 drives the threaded rod 13 to rotate in the opposite direction, retracting the moving frame 15 and the polarizing mirror 16 into the connecting shell 11, thereby releasing the obstruction of the lens of the camera body 6. When the external light intensity is relatively low, the image captured by the camera body 6 is not affected by the polarizing mirror 16, thus maintaining clarity as much as possible and improving the practicality of the device.
[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0037] Example 1:
[0038] Please refer to Figures 1-4 A light-sensing adjustment device for an image recognition drone, comprising:
[0039] The drone body 1 has a fixed shell 2 fixedly connected to its bottom. A rotating cover 3 is rotatably connected to the outer wall of the fixed shell 2. A fixed frame 4 is fixedly installed on the outer wall of the rotating cover 3. A rotating shaft 5 is rotatably connected to the inner wall of the fixed frame 4. A camera body 6 is fixedly installed on the outer wall of the rotating shaft 5. A shielding mechanism 7 is provided on the camera body 6. An adjustment mechanism 8 is provided on the fixed frame 4. A positioning module body 9 is fixedly installed on the outer wall of the rotating cover 3.
[0040] The blocking mechanism 7 includes a support shell 10, a connecting shell 11, a light intensity sensor 17, a driving component, and a blocking component. Two support shells 10 are fixedly connected to the outer wall of the camera body 6, and a connecting shell 11 is fixedly connected between the two support shells 10. A light intensity sensor 17 is fixedly installed on the outer wall of the connecting shell 11. The blocking mechanism 7 can block the lens of the camera body 6 according to the intensity of light in the external environment to ensure the clarity of the image captured by the camera body 6. The light intensity sensor 17 is model BH1750FVI.
[0041] The driving assembly includes a fixed rod 12, which is fixedly connected to the inner wall of the connecting shell 11. The outer wall of the fixed rod 12 is fixedly connected to the inner wall of one of the supporting shells 10. A threaded rod 13 is rotatably connected to the inner wall of the connecting shell 11, and the threaded rod 13 is rotatably connected to the inner wall of the other supporting shell 10. A first motor 14 is fixedly installed on the outer wall of the connecting shell 11, and the output end of the first motor 14 is fixedly connected to the inner wall of the threaded rod 13. The driving assembly can drive the blocking assembly to move accordingly. When it is not necessary to block the lens of the camera body 6, the blocking assembly can be driven into the connecting shell 11 to provide a certain degree of protection for the blocking assembly. A processor is provided on the connecting shell 11 to process the relationship between light intensity, light intensity sensor 17 and the first motor 14. The external light intensity is monitored in real time by the light intensity sensor 17. The signal detected by the light intensity sensor 17 is transmitted to the processor. The processor determines whether the position of the sunglasses needs to be adjusted according to the preset light intensity threshold and sends a signal to the first motor 14.
[0042] The blocking component includes a movable frame 15. The outer wall of the threaded rod 13 is threadedly connected to the movable frame 15. The movable frame 15 is slidably connected to the outer wall of the fixed rod 12. The inner wall of the movable frame 15 is fixedly connected to a polarizing filter 16. The blocking component can block the lens of the camera body 6 to a certain extent, thereby reducing the adverse effects of external light on the image captured by the camera body 6.
[0043] With the above structural design, after the device is placed in a suitable working position, the light intensity sensor 17 can detect the intensity of the external light. When the external sunlight is strong, the first motor 14 will drive the threaded rod 13 to rotate, causing the moving frame 15 to move under the restriction of the fixed rod 12. Then, the polarizing mirror 16 will block the lens of the camera body 6. When the light intensity sensor 17 detects that the external light is weak, the first motor 14 will drive the threaded rod 13 to rotate in the opposite direction, so that the moving frame 15 and the polarizing mirror 16 can be put into the connecting shell 11, thereby releasing the obstruction of the lens of the camera body 6.
[0044] Example 2:
[0045] The light perception and adjustment device for the image recognition UAV provided in Example 1 has been further optimized, specifically, as follows: Figures 2-6As shown, the adjustment mechanism 8 includes a protective shell 18, a third motor 24, a transmission assembly, and a rotation assembly. The protective shell 18 is fixedly connected to the outer wall of the fixed frame 4 and to the left and right sides of the camera body 6. The third motor 24 is fixedly installed on the inner wall of the fixed shell 2. The output end of the third motor 24 is fixedly connected to the inner wall of the rotating cover 3. The third motor 24 drives the rotating cover 3 to rotate relative to the fixed shell 2, which allows the camera body 6 to rotate in the horizontal plane. The protective shell 18 can reduce the dust and other impurities adhering to the drive gear 23 and the sector gear 19, thereby reducing the wear caused by dust or other small particles during the meshing motion of the sector gear 19 and the drive gear 23, and extending the service life of the device.
[0046] The transmission assembly includes a second motor 22. The second motor 22 is fixedly installed on the outer wall of the fixed frame 4. A rotating rod 21 is rotatably connected to the inner wall of the fixed frame 4. The rotating rod 21 is rotatably connected to the inner walls of the two protective shells 18. The output end of the second motor 22 is fixedly connected to the inner wall of the rotating rod 21. A drive gear 23 is fixedly connected to the outer wall of the rotating rod 21 and located inside the two protective shells 18. The transmission assembly is used to adjust the pitch angle of the camera body 6.
[0047] The rotating assembly includes a sector gear 19. The sector gear 19 is fixedly connected to the outer wall of the rotating shaft 5 and located inside the two protective shells 18. The sector gear 19 meshes with the outer wall of the drive gear 23. The inner walls of the two protective shells 18 are fixedly connected to limiting rods 20. The limiting rods 20 are slidably connected to the inner walls of the sector gear 19. The rotating assembly allows the rotating shaft 5 to rotate on the fixed frame 4, thereby moving the camera body 6. An arc-shaped groove is provided on the sector gear 19. The limiting rod 20 slides in the arc-shaped groove, which can limit the degree of rotation of the sector gear 19 and ensure the stability of the tilt angle adjustment of the camera body 6.
[0048] Through the above structural design, the positioning module 9 positions the drone body 1, and then the third motor 24 and the second motor 22 rotate the camera body 6 to face the drone, so that the camera body 6 can collect information. The third motor 24 can drive the rotating cover 3 to rotate on the outer wall of the fixed shell 2, thereby driving the camera body 6 to rotate in the horizontal plane to adapt to the position of the drone. The second motor 22 can drive the rotating rod 21 to rotate, thereby causing the two active gears 23 to rotate, which in turn causes the two sector gears 19 to rotate and slide relative to the limiting rod 20, thereby adjusting the pitch angle of the camera body 6.
[0049] In this application, the first motor 14, the second motor 22 and the third motor 24 are all stepper motors with self-locking function. Stepper motors with self-locking function are existing technology, so they will not be described in detail.

The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply ground is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
