Description

Technical Field

[0001] This invention relates to the field of surveying and mapping technology, and in particular to an intelligent acquisition device for UAV surveying and mapping images and its usage method. Background Technology

[0002] Surveying work often requires fieldwork under harsh conditions. In recent years, with the development of drone technology, drone-based aerial photography tools have been increasingly used in surveying engineering. These tools mainly involve mounting surveying data acquisition devices on drones, which then move the data acquisition devices to any area to capture images of different terrains. This provides a good equipment foundation for saving manpower and improving personnel safety.

[0003] However, in actual use, the installation mechanism is often quite troublesome, making the installation and disassembly of the surveying and mapping data acquisition device difficult to maintain or use.

[0004] Furthermore, the lack of protection for the mapping and data acquisition equipment during flight allowed dust to easily accumulate on the lens. The inability to clean the lens promptly resulted in inaccurate images.

[0005] To address the aforementioned problems, this invention proposes an intelligent acquisition device for UAV mapping images and its usage method. Summary of the Invention

[0006] This invention provides an intelligent image acquisition device for UAV mapping and its usage method, which solves the shortcomings of the prior art, such as the inability to easily install or remove the mapping acquisition device from the UAV, and the inability to protect the mapping acquisition device.

[0007] This invention provides the following technical solution:

[0008] A drone-based intelligent image acquisition device includes an upper frame, with columns fixedly installed at the four bottom corners of the upper frame. A lower frame is fixedly installed at the bottom of the four columns. Two uprights are symmetrically fixedly installed on the top of the lower frame, with the tops of both uprights fixedly connected to the bottom of the upper frame. The acquisition device also includes:

[0009] The mounting mechanism is installed on the drone and is snapped into the upper frame.

[0013] In one possible design, the mounting mechanism includes a U-shaped plate inserted into the upper frame, the U-shaped plate contacting the inner wall of the upper frame, multiple bolt holes evenly spaced on the U-shaped plate, and sliding plates slidably connected to both inner walls of the U-shaped plate. Movable plates are fixedly installed on the sides of the two plates that are close to each other, and the movable plates are slidably connected to the U-shaped plate. An adjustment assembly is installed at the bottom of the U-shaped plate, and the adjustment assembly is connected to the sides of the two movable plates that are close to each other. Two slots are symmetrically opened at the bottom of the U-shaped plate, and the adjustment assembly is movably engaged with each of the two slots.

[0014] In one possible design, the adjustment assembly includes a mounting shaft fixedly installed at the bottom of the U-shaped plate.

The connecting rod is fixedly connected to a corresponding movable plate. Two insert rods are symmetrically slidably connected through the rocker arm. The top ends of the insert rods extend into corresponding slots and engage with the slots. The same pull plate is fixedly installed at the bottom ends of the two insert rods. A tension spring located below the rocker arm is sleeved on the insert rod. The top and bottom ends of the tension spring are fixedly connected to the bottom of the rocker arm and the top of the pull plate, respectively.

[0015] In one possible design, multiple fixing plates are fixedly installed at equal intervals on both sides of the U-shaped plate, and positioning rods are fixedly installed at the bottom of the fixing plates. Multiple positioning plates are fixedly installed at equal intervals on both sides of the upper frame. Positioning holes are opened on the positioning plates, and positioning rods are inserted into the corresponding positioning holes and engaged with the positioning holes.

[0016] In one possible design, the angle adjustment mechanism includes a stepper motor fixedly mounted on one side of the upright plate. The output shaft of the stepper motor passes through the upright plate and is fixedly mounted with a transmission screw. One end of the transmission screw is rotatably connected to the upright plate on the other side. A threaded plate is threaded onto the transmission screw. Two drive rods are symmetrically fixedly mounted on the bottom of the threaded plate. The bottom end of the two drive rods is equipped with the same gear assembly. The gear assembly is connected to the inner walls of the two upright plates and the lower frame on both sides, respectively. The bottom of the gear assembly extends to the bottom of the lower frame and is connected to the protective mechanism.

[0017] In one possible design, the gear assembly includes a guide rail, with both ends of the guide rail fixedly connected to two upright plates respectively. A slide bar is slidably connected inside the guide rail, and the bottom of the slide bar extends to the bottom of the guide rail and is fixedly installed with an adjusting plate. Two drive rods are fixedly connected to the top of the adjusting plate, and a rack is fixedly installed at the bottom of the adjusting plate. A rotating shaft is rotatably connected inside the lower frame, and a gear is fixedly sleeved on the rotating shaft. The rack meshes with the gear, and two connecting plates are symmetrically fixedly sleeved on the rotating shaft. The bottom of both connecting plates extends to the bottom of the lower frame and is connected to the protective mechanism.

[0018] In one possible design, the protective mechanism includes a mounting frame that is fixedly connected to the bottom of two connecting plates. Support components are installed on the inner walls of both sides of the mounting frame. The same transparent spherical cover is fitted onto the two support components. The same support bracket is installed on the side of the two support components that are close to each other. An image acquisition camera is fixedly installed inside the support bracket. A cleaning mechanism is installed on the mounting frame and is used to clean the transparent spherical cover.

[0019] In one possible design, the support assembly includes a mounting rod fixedly mounted on the inner wall of one side of the mounting bracket, a mounting cover fixedly mounted on the inner wall of the transparent spherical cover, a second limiting ring fixedly mounted on one side of the mounting cover, a fixing rod rotatably connected inside the second limiting ring, one end of the fixing rod extending into the transparent spherical cover and fixedly connected to one side of the support bracket, one end of the mounting rod extending into the second limiting ring and fixedly connected to the other end of the fixing rod, a support ring fixedly sleeved on the mounting rod inside the mounting cover, a first limiting ring rotatably sleeved on the support ring, and the first limiting ring fixedly mounted inside the mounting cover.

[0020] In one possible design, the cleaning mechanism includes a drive motor fixedly mounted on the bottom of one side of the mounting frame. The output shaft of the drive motor extends into the mounting frame and a transmission shaft is fixedly mounted thereon. One end of the transmission shaft is rotatably connected to the bottom of one side of the mounting frame. A drive roller is fixedly sleeved on the transmission shaft. Multiple arc-shaped grooves are equally spaced on the drive roller. The drive roller contacts the transparent spherical cover and is used to drive the transparent spherical cover to rotate. A scraper is fixedly mounted on the inner top wall of the mounting frame and contacts the transparent spherical cover.

[0021] The method of using the aforementioned UAV mapping image intelligent acquisition device includes the following steps:

[0022] S1. Frame and U-shaped plate engagement: When engaging the upper frame and U-shaped plate, align the positioning rods and positioning holes to maintain lateral stability and ensure stable installation of the image acquisition camera.

[0023] S2. Rocker-driven mounting: Rotating the rocker causes the collar to move in an arc shape, which, through the sliding engagement of the connecting rod, moves the moving plate so that the insertion rod aligns with the slot; releasing the pull plate stretches the spring to pull the insertion rod into the slot, positioning and braking the rocker, and stabilizing the mounting plate and the upper frame.

[0024] S3. Start the drone: Start the drone and fly the device to the shooting area.

[0025] S4. Adjusting the pitch angle: Start the stepper motor, rotate the transmission screw, and move the threaded plate through the threaded transmission; when the threaded plate moves, it drives the adjustment plate and rack to move through the drive rod; the rack and gear mesh to drive the rotating shaft to rotate, and then adjust the angle of the protective mechanism through the connecting plate to realize the adjustment of the pitch angle of the image acquisition camera.

[0026] S5. Cleaning the transparent spherical cover: Start the drive motor and rotate the transmission shaft and drive roller; under the action of static friction, drive the transparent spherical cover to rotate; the scraper cleans the rotating transparent spherical cover and keeps its outer surface clean.

[0027] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] In this invention, the installation mechanism allows the upper frame to be engaged with the U-shaped plate after it has been pre-installed on the drone. Then, the adjustment component can be operated to drive the two moving plates away from each other, so that the two plates can contact the bottom of the upper frame. This allows the upper frame to be engaged with the U-shaped plate, facilitating the installation of the image acquisition camera.

[0030] In this invention, by setting an angle adjustment mechanism, the stepper motor can be started to drive the transmission screw to rotate. At this time, under the action of thread transmission, the thread plate can be driven to move laterally. When the thread plate moves, the gear assembly can be driven to run through two drive rods, thereby driving the protective mechanism to rotate and adjust, so as to adjust the angle captured by the image acquisition camera.

[0031] In this invention, the protective mechanism allows for the installation and support of the transparent spherical cover using two support components. After the image acquisition camera is installed in the support frame, the transparent spherical cover can protect it, thereby preventing the image acquisition camera from being interfered with by dust and ensuring that the captured image remains clear.

[0032] In this invention, the cleaning mechanism can be set up so that the drive motor can drive the transmission shaft to rotate, which in turn drives the drive roller to rotate. Under the action of the scraper, the rotating transparent spherical cover can be cleaned so that its outer surface remains clean.

[0033] This invention enables easy installation of an image acquisition camera on a drone, providing convenience during installation and removal. Furthermore, it prevents dust from falling onto the image acquisition camera during shooting, ensuring that the image remains clear. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0047] Example 1

[0048] Reference Figures 1-9 The UAV mapping image intelligent acquisition device of this embodiment includes an upper frame 1, a column 2, a lower frame 3, a vertical plate 4, as well as an installation mechanism, an angle adjustment mechanism, a protection mechanism and a cleaning mechanism.

[0049] First, the four uprights 2 are fixedly installed at the four bottom corners of the upper frame 1, ensuring that the uprights 2 are vertical and stable. Next, the bottom ends of these four uprights 2 are fixedly connected to the same lower frame 3 to form a stable support structure. Subsequently, two upright plates 4 are symmetrically installed on the top of the lower frame 3, and the tops of the two upright plates 4 are then fixedly connected to the bottom of the upper frame 1 to enhance the stability and rigidity of the overall structure.

[0050] Prepare a U-shaped plate 5, slightly smaller than the inner cavity size of the upper frame 1, ensuring that the U-shaped plate 5 can be smoothly inserted into the upper frame 1 and make tight contact with the inner wall of the upper frame 1. Make multiple bolt holes 52 at equal intervals on the U-shaped plate 5 for subsequent bolt fixing.

[0051] On the inner walls of both sides of the U-shaped plate 5, a retaining plate 91 is slidably connected. A movable plate 9 is fixedly installed on the side of the two retaining plates 91 that are close to each other. The movable plate 9 is slidably connected to the side wall of the U-shaped plate 5 to ensure smooth movement.

[0052] A mounting shaft 51 is installed at the bottom of the U-shaped plate 5, and a rocker arm 6 is rotatably connected to the bottom end of the mounting shaft 51. Connecting brackets 71 are rotatably connected to both ends of the rocker arm 6, and a collar 7 is fixedly installed on the other side of the connecting brackets 71. A sliding connecting rod 8 passes through the collar 7, and the other end of the connecting rod 8 is fixedly connected to the corresponding movable plate 9.

[0053] Insert rods and tension springs: Two insert rods 10 are symmetrically slidably connected through the rocker arm 6. The top end of the insert rod 10 extends into a slot at the bottom of the U-shaped plate 5 for locking and fixing. The bottom end of the insert rod 10 is fixedly connected to the pull plate 11, and a tension spring 12 is sleeved on the insert rod 10. The top and bottom ends of the tension spring 12 are fixedly connected to the bottom of the rocker arm 6 and the top of the pull plate 11, respectively, to provide elastic force so that the insert rod 10 can automatically lock into the slot.

[0054] Installation and Fixing: The U-shaped plate 5 is pre-installed on the drone, and then the upper frame 1 is engaged with the U-shaped plate 5. At this point, the pry bar 6 is operated to rotate, causing the two collars 7 to move in an arc shape. This, in turn, pushes the moving plate 9 and the locking plate 91 away from each other via the connecting rod 8, until the locking plate 91 is in tight contact with the bottom of the upper frame 1, achieving the locking mechanism. Subsequently, the pull plate 11 is released, and the tension of the spring 12 causes the insertion rod 10 to automatically insert into the corresponding slot, completing the final fixation.

[0055] Multiple fixing plates 13 are fixedly installed at equal intervals on both sides of the U-shaped plate 5, and a positioning rod 14 is installed at the bottom of each fixing plate 13. At the same time, positioning holes are opened at equal intervals on corresponding positions on both sides of the upper frame 1, and the positioning rods 14 are inserted into the corresponding positioning holes to enhance the lateral stability between the U-shaped plate 5 and the upper frame 1, and ensure that the image acquisition camera 30 can be stably installed.

[0056] A stepper motor 38 is fixedly installed on one of the upright plates 4, ensuring that the stepper motor 38 is stable and does not wobble. Then, the output shaft of the stepper motor 38 is passed through the upright plate 4, and a transmission screw 39 is fixedly installed at its end. The other end of the transmission screw 39 passes through and is rotatably connected to the upright plate 4 on the other side, ensuring that the transmission screw 39 can rotate freely without affecting the structural stability of the upright plates 4 on both sides.

[0057] A threaded plate 40 is threaded onto the transmission screw 39 to ensure a tight fit and to drive the threaded plate 40 to move laterally when the transmission screw 39 rotates. Two drive rods 41 are symmetrically fixed at the bottom of the threaded plate 40, and the bottom ends of these two drive rods 41 are connected to the gear assembly.

[0058] First, a guide rail 16 is fixedly installed between the two upright plates 4, and a slide bar 17 is slidably connected within the guide rail 16. The bottom of the slide bar 17 extends below the guide rail 16 and is fixedly installed with an adjusting plate 18. The ends of both drive rods 41 are fixedly connected to the top of the adjusting plate 18 to ensure that the movement of the drive rods 41 can drive the adjusting plate 18 to move. A rack 19 is fixedly installed at the bottom of the adjusting plate 18, and a rotating shaft 20 is rotatably connected within the lower frame 3. A gear 21 is fixedly sleeved on the rotating shaft 20 so that the rack 19 meshes with the gear 21. Two connecting plates 22 are symmetrically fixedly sleeved on the rotating shaft 20, and the bottom of the connecting plates 22 extends below the lower frame 3, ready to be connected to the protective mechanism.

[0059] The stepper motor 38 is started, and its output shaft drives the transmission screw 39 to rotate, which in turn drives the threaded plate 40 to move laterally through the threaded transmission. The movement of the threaded plate 40 is transmitted to the adjusting plate 18 through the drive rod 41, causing the adjusting plate 18 to drive the rack 19 to move. The movement of the rack 19 meshes with the gear 21, thereby driving the rotating shaft 20 to rotate. The rotation of the rotating shaft 20 then drives the two connecting plates 22 to rotate, ultimately realizing the adjustment of the shooting angle of the protective mechanism and the image acquisition camera 30.

[0060] The mounting bracket 23 is fixedly connected to the bottom of the two connecting plates 22 to ensure that the mounting bracket 23 is stable and does not wobble. Support components are installed on the inner walls of both sides of the mounting bracket 23. Each support component includes a mounting rod 24, one end of which is fixed to the mounting bracket 23, and the other end extends into the second limiting ring 36 inside the transparent spherical cover 25 and is fixedly connected to one end of a fixing rod 28. The other end of the fixing rod 28 is fixedly connected to one side of a support bracket 29, and the image acquisition camera 30 is fixedly installed inside the support bracket 29.

[0061] A mounting cover 27 is fixedly installed on the inner wall of the transparent spherical cover 25. The mounting cover 27 contains a support ring 32, a first limiting ring 31, and other structures to provide rotational support for the transparent spherical cover 25. The support ring 32 is sleeved on the mounting rod 24 and rotates in cooperation with it, while the first limiting ring 31 is fixedly installed inside the mounting cover 27. Together, they ensure that the transparent spherical cover 25 can rotate smoothly.

[0062] Example 2

[0063] Reference Figure 6 and Figure 8 Based on Embodiment 1, this embodiment, regarding the UAV mapping image intelligent acquisition device proposed in Embodiment 1, has a drive motor 33 fixedly installed on the bottom side of one side of the mounting frame 23, with its output shaft extending into the mounting frame 23 and fixedly connected to a transmission shaft 34. The other end of the transmission shaft 34 is rotatably connected to the bottom side of the other side of the mounting frame 23, ensuring that the transmission shaft 34 can rotate freely.

[0064] A drive roller 35 is fixedly sleeved on the drive shaft 34, and multiple arc-shaped grooves 37 are equally spaced on the drive roller 35 to ensure close contact with the outer surface of the transparent spherical cover 25 without generating excessive friction. At the same time, a scraper 26 is fixedly installed on the top inner wall of the mounting frame 23. The scraper 26 contacts the outer surface of the transparent spherical cover 25 and is used to scrape off dust.

[0065] The drive motor 33 is started, and its output shaft drives the transmission shaft 34 to rotate, which in turn drives the drive roller 35 to rotate. The static friction between the drive roller 35 and the transparent spherical cover 25 drives the transparent spherical cover 25 to rotate slowly. During the rotation, the scraper 26 continuously scrapes the outer surface of the transparent spherical cover 25 to remove attached dust and other impurities, keeping the transparent spherical cover 25 clean, thereby ensuring the clarity of the image captured by the image acquisition camera 30.

[0066] This invention proposes a method for using an intelligent image acquisition device for UAV mapping, characterized by the following steps:

[0067] S1. When the upper frame 1 and the U-shaped plate 5 are engaged, multiple positioning rods 14 can be aligned with the positioning holes. This ensures that the lateral position of the U-shaped plate 5 and the upper frame 1 does not change when the positioning rods 14 and the positioning plate 15 are engaged, thereby enabling stable installation of the image acquisition camera 30.

[0068] S2. By rotating the rocker arm 6, the two collars 7 can be driven to move in an arc. At this time, under the sliding cooperation between the collars 7 and the corresponding connecting rods 8, the moving plate 9 can be driven to move laterally until the insertion rod 10 is moved to correspond to the corresponding slot. At this time, the pull plate 11 can be released, and the tension spring 12 under force can pull the pull plate 11 to move upward, so that the insertion rod 10 is inserted into the corresponding slot, and the rocker arm 6 is positioned and braked, so that the locking plate 9 and the upper frame 1 can be stably locked.

[0069] S3. Start the drone and fly this device to the area where you need to take pictures;

[0070] S4. When it is necessary to adjust the pitch angle of the image acquisition camera 30, the stepper motor 38 can be started to drive the transmission screw 39 to rotate. At this time, under the action of the screw transmission, the screw plate 40 can be driven to move laterally. When the screw plate 40 moves, the two drive rods 41 can drive the adjustment plate 18 to move. When the adjustment plate 18 moves, it can drive the rack 19 to move. Thus, under the meshing transmission action with the gear 21, the rotating shaft 20 can be driven to rotate. When the rotating shaft 20 rotates, it can drive the two connecting plates 22 to rotate. Therefore, the angle set by the protective mechanism can be adjusted through the two connecting plates 22 so as to adjust the pitch angle of the image acquisition camera 30.

[0071] S5. Since the transparent spherical cover 25 is rotated and supported by two mounting covers 27, when cleaning the transparent spherical cover 25, the drive motor 33 can be started to drive the transmission shaft 34 to rotate. At this time, the drive roller 35 can be driven to rotate. Under the transmission action of the static friction between the drive roller 35 and the transparent spherical cover 25, the transparent spherical cover 25 can be driven to rotate. Under the action of the scraper 26, the rotating transparent spherical cover 25 can be cleaned, so that the outer surface of the transparent spherical cover 25 is in a clean state.

[0072] However, as is well known to those skilled in the art, the working principles and wiring methods of the image acquisition camera 30, the drive motor 33 and the stepper motor 38 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0073] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.
