Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to an UAV aerial photography and mapping device. Background Technology

[0002] With the rapid development of drone technology, drone aerial surveying has been widely used in fields such as land resource surveys, urban planning, and disaster monitoring. The high-precision cameras carried by drones can efficiently acquire surface image data and generate surveying results such as orthophoto maps and 3D models through post-processing.

[0003] Existing UAV mapping devices mostly use fixed-mount cameras, rigidly connected to the UAV fuselage, whose attitude is entirely dependent on the UAV's flight state. When the UAV flies at high speed or performs maneuvers, the dynamic adjustment of the fuselage causes the camera to tilt synchronously, resulting in a large tilt angle in the captured image. This tilted image not only increases the workload of post-processing image correction but also reduces mapping accuracy due to occlusion and distortion, and may even fail to meet the requirements of large-scale mapping.

[0004] To address these issues, we provide an unmanned aerial vehicle (UAV) aerial mapping device. Utility Model Content

[0005] The purpose of this invention is to provide a drone aerial photography and mapping device that solves the problem that existing drone aerial photography and mapping devices cannot dynamically adjust the camera level during use by using an automatic leveling mechanism and a limiting mechanism.

[0013] The present invention is further configured such that a support rod is fixedly connected to the top of the limiting shell, a limiting slider is fixedly connected to the top of the support rod, and the limiting slider is slidably connected to the UAV body.

Detailed Implementation

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5 This utility model relates to an unmanned aerial vehicle (UAV) aerial surveying and mapping device, comprising a UAV body 1. The UAV body 1 is an unmanned aerial vehicle, controlled by remote control or an autonomous system, and is typically used in various fields such as military, commerce, scientific research, agriculture, and entertainment. With the continuous development of technology, the functions and application scenarios of UAVs are becoming increasingly widespread. As this is a mature existing technology, it will not be elaborated further here. A surveying camera 2 is installed at the bottom of the UAV body 1. The UAV body 1 serves as a flight platform, carrying the surveying camera 2 and other auxiliary equipment, providing power and flight control functions. The surveying camera 2 is used to capture high-precision surface images and acquire surveying data. An automatic leveling mechanism 3 is installed at the bottom of the UAV body 1. The automatic leveling mechanism 3 includes a mounting shell 31 located at the bottom of the UAV body 1, a rotating frame 32 fixedly connected to the top of the mounting shell 31, and a fixed connection... A counterweight 33 attached to one side of the mounting shell 31 automatically adjusts the horizontal state of the mounting shell 31 and the mapping camera 2 when the UAV tilts, ensuring that the captured image is perpendicular to the ground. A limiting mechanism 4 is provided on the surface of the mounting shell 31. The limiting mechanism 4 includes a limiting shell 41 set on the surface of the mounting shell 31, a rotating frame 32 rotatably connected to the limiting shell 41 through a bearing, and an airbag 42 fixedly connected to one side inside the limiting shell 41. The limiting shell 41 supports and fixes other limiting components. The airbag 42 buffers the swing during the leveling process through gas flow, enhancing stability.

[0028] Example 2

[0029] Please see Figures 1-5 Based on Embodiment 1, the limiting mechanism 4 further includes a conduit 43 connected to one side of the airbag 42. The airbag 42 is in contact with the mounting shell 31. There are two airbags 42, which are horizontally symmetrically designed. The two airbags 42 are connected by the conduit 43. A one-way valve 44 is sleeved on the surface of the conduit 43. The conduit 43 and the one-way valve 44 control the unidirectional flow of gas between the airbags 42 to prevent gas backflow and shaking. The limiting mechanism 4 also includes a cylinder 45 fixedly connected to one side of the limiting shell 41, and a limiting plate 46 fixedly connected to the output end of the cylinder 45. An anti-slip pad is fixedly connected to one side of the limiting plate 46. The anti-slip pad is in contact with the mounting shell 31. The cylinder 45 drives the limiting plate 46 to clamp or loosen the mounting shell 31, fixing or releasing the leveling mechanism. A motor 5 is fixedly connected to the bottom of the UAV body 1. The output end of the motor 5 is fixedly connected to the limiting shell 41. The motor 5 drives the limiting shell 41 and the leveling mechanism to rotate as a whole to adjust the mapping. Camera 2 is oriented to adapt to the flight direction of the UAV. A mounting block 6 is fixedly connected to one side of the mapping camera 2. A mounting groove 7 is opened on one side of the mounting block 6. The size of the mounting groove 7 is adapted to the limiting block 9. A threaded rod 8 is threadedly connected to one side of the mounting shell 31. A limiting block 9 is fixedly connected to one side of the threaded rod 8. A handwheel 10 is fixedly connected to the other side of the threaded rod 8. The limiting block 9 and the mounting groove 7 are used for quick installation and removal of the mapping camera 2, which is convenient for maintenance or equipment replacement. By manually rotating the handwheel 10, the threaded rod 8 is driven to move the limiting block 9, thereby realizing the mechanical locking or release of the mapping camera 2. A support rod is fixedly connected to the top of the limiting shell 41. A limiting slider is fixedly connected to the top of the support rod. The limiting slider is slidably connected to the UAV body 1. A limiting groove adapted to the limiting slider is opened at the bottom of the UAV body 1. The support rod and the limiting slider support the limiting shell 41 and make it slide along the limiting groove at the bottom of the UAV body 1, ensuring that the limiting shell 41 rotates smoothly.

[0030] The working principle of this utility model is as follows: the cylinder 45 drives the limiting plate 46 and the anti-slip pad to move, releasing the leveling mechanism. When the drone body tilts, the counterweight 33 drives the mounting shell 31 and the mapping camera 2 to rotate around the rotating frame 32, restoring it to a horizontal state. During the rotation, the mounting shell 31 squeezes one side of the airbag 42, and the gas flows into the other side of the airbag 42 through the conduit 43 and the one-way valve 44 to avoid swaying and ensure a smooth leveling process. After leveling is completed, the cylinder 45 drives the limiting plate 46 to clamp the mounting shell 31 and fix its position with the anti-slip pad to prevent the mapping camera 2 from shaking during flight. The motor 5 can drive the limiting shell 41 to rotate as a whole and adjust the orientation of the mapping camera 2 to adapt to the flight direction of the drone.

[0031] During disassembly, rotating the handwheel 10 drives the threaded rod 8 to move the limiting block 9, disengaging it from the mounting slot 7, thus removing the surveying camera 2. During installation, the operation is reversed, locking the limiting block 9 through the threaded rod 8 to ensure a stable connection of the surveying camera 2. The support rod and the limiting slider slide along the groove at the bottom of the UAV to ensure the stability of the limiting shell 41 during rotation. Through the above design, dynamic leveling of the surveying camera 2 is achieved during UAV aerial surveying, solving the image quality problem caused by the tilt of the body of the traditional fixed surveying camera 2, and significantly improving surveying efficiency and the reliability of results.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
