Description

Technical Field

[0001] This utility model relates to the field of drone image acquisition technology, and more specifically, to a drone oblique photography image acquisition device. Background Technology

[0002] As an aircraft that flies through remote control or autonomous programs, drones have become an important tool for aerial observation and data collection. Their core systems include the aircraft itself, flight control system, power system, remote sensing equipment, and ground control system. They can replace humans in dangerous, remote, or repetitive work environments to complete data collection tasks at low cost and high efficiency, and are widely used in fields such as aerial surveying and mapping, agricultural plant protection, and power line inspection.

[0003] In aerial surveying and 3D modeling scenarios, traditional UAV orthophotography can only acquire a "top view" of the ground or objects, failing to capture side details and making it difficult to fully restore the 3D shape of buildings and terrain. Existing oblique photogrammetry devices, in order to achieve 3D data acquisition, usually need to be equipped with multiple cameras corresponding to different shooting angles. Although they can acquire top and side images, the multi-camera configuration significantly increases the hardware cost of the UAV. At the same time, the additional camera weight increases the load on the UAV's power system, shortens the flight time, and the multi-camera calibration operation is complicated, raising the threshold for use and maintenance costs, which is not conducive to the widespread application of oblique photogrammetry technology. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drone oblique photography image acquisition device, which aims to solve the problems mentioned in the background art.

[0019] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment discloses a drone oblique photography image acquisition device, which aims to solve the problem of high cost caused by the installation of multiple cameras in the existing drone oblique photography device.

[0021] Specifically, the device includes a mounting plate 1, which serves as the core support structure. The bottom of the mounting plate 1 is provided with an adjustment component for adjusting the angle and position of the camera, and the top is provided with a limiting structure for fixing the position of the adjustment component.

[0022] The adjustment assembly includes a connecting frame 2 slidably connected to the bottom of the mounting plate 1. The connecting frame 2 adopts a rectangular frame structure, which ensures structural stability and facilitates sliding adjustment in conjunction with the mounting plate 1. A support cylinder 3 is detachably installed in the middle of the connecting frame 2 via bolts. The bolt connection facilitates the disassembly and maintenance of the support cylinder 3. A hinge frame 4 is fixedly installed in the middle of the support cylinder 3, and a camera 5 is movably connected to the middle of the hinge frame 4. The camera 5 can rotate around the hinge frame 4 to adjust its vertical angle. The camera 5 passes through one end of the support cylinder 3 and extends to the outside of the support cylinder 3. The support cylinder 3 can provide a certain degree of protection and limit the movement of the camera 5, preventing excessive displacement of the camera 5 during adjustment.

[0023] A limiting plate 6 is welded and fixed to the top of the mounting plate 1. A limiting rod 7 is rotatably connected to the limiting plate 6 via a pin. The limiting rod 7 can rotate freely around the pin. When the connecting frame 2 slides to the target position on the mounting plate 1, the limiting rod 7 is rotated so that it abuts against the outside of the connecting frame 2. The sliding of the connecting frame 2 is restricted by friction, thereby fixing the position of the connecting frame 2.

[0024] One end of the mounting plate 1 is integrally formed with a connector 8, and a first adjusting rod 9 is threadedly connected to the connector 8. The threaded connection facilitates the disassembly and assembly of the first adjusting rod 9 and fine-tuning of its length. One end of the first adjusting rod 9 is provided with an angle-adjustable adjusting block 10. The end of the adjusting block 10 away from the first adjusting rod 9 is rotatably connected to a second adjusting rod 11 via a rotating shaft. The second adjusting rod 11 can rotate around the rotating shaft relative to the adjusting block 10 to achieve left and right angle adjustment. One end of the second adjusting rod 11 is welded and fixed with a mounting block 12 for mounting on the drone. The mounting block 12 has mounting holes, and the entire device can be fixed to the designated position on the drone with bolts.

[0025] Two locking screws 13 are threaded onto the adjusting block 10, with one end of each locking screw 13 extending to the first adjusting rod 9 and the second adjusting rod 11, respectively. After the relative angles between the first adjusting rod 9 and the adjusting block 10, and between the second adjusting rod 11 and the adjusting block 10, are adjusted to the target angles, the corresponding locking screws 13 are tightened. The increased friction between the locking screws 13 and the first adjusting rod 9 and the second adjusting rod 11 achieves the fixation of the angles between the first adjusting rod 9, the second adjusting rod 11, and the adjusting block 10.

[0026] The specific working principle is as follows: First, the entire device is fixedly installed on the drone by the mounting block 12. According to the installation position of the drone and the initial data collection requirements, the relative angle between the first adjusting rod 9 and the adjusting block 10 and the relative angle between the second adjusting rod 11 and the adjusting block 10 are adjusted. After the adjustment is completed, the two locking screws 13 are tightened to fix the relative position and angle between the entire device and the drone.

[0027] If it is necessary to adjust the left and right position of camera 5, the limiting rod 7 can be loosened, and the connecting frame 2 can be pushed to slide on the mounting plate 1. After sliding to the target position, the limiting rod 7 can be rotated again to contact the connecting frame 2, thus completing the adjustment of the left and right position of camera 5.

[0028] If it is necessary to adjust the up and down shooting angle of camera 5, camera 5 can be directly pushed to rotate around hinge frame 4. After rotating to the target angle, a fastening bolt can be added to the connection position between hinge frame 4 and camera 5 for locking.

[0029] Through the above multi-dimensional adjustments, a single camera can capture images of the ground or the top and sides of objects from different angles, eliminating the need for multiple cameras and effectively reducing the cost of the drone, while also meeting the requirements of oblique photography for three-dimensional shape reproduction.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
