Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) surveying and mapping technology, specifically to an automatic data acquisition device for multi-view surveying and mapping based on UAVs. Background Technology

[0002] As is well known, the current surveying and mapping field, especially when using drones for geographic information data collection, faces a series of technical and operational challenges. These challenges not only limit work efficiency but also affect the quality and comprehensiveness of the data. Traditional drone surveying equipment is usually equipped with a single camera or sensor, which means that each flight can only acquire ground images or data from a fixed angle. This limitation leads to the need for multiple flights to cover different angles, increasing the time cost and complexity of the project. In addition, data from a single perspective often cannot provide enough detail to meet the needs of accurate surveying, especially in scenarios with complex terrain or multi-layered structures. Existing drone surveying equipment is often cumbersome to install and adjust. For example, changing different types of cameras or sensors may require complex tools and a long time, which is not ideal for rapid response tasks. Furthermore, in order to obtain multi-angle data, it is sometimes necessary to manually adjust the angle or position of the camera, which is not only inefficient but also prone to introducing human error. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-4This utility model relates to an automatic data acquisition device for multi-view mapping based on a drone, comprising a mounting plate 1, which is equipped with a mounting mechanism, an anti-collision mechanism, and a wireless control mechanism. The bottom end of the mounting plate 1 has a threaded hole and a mounting groove. Four mounting grooves are arranged in a circular array around the threaded hole. Each mounting groove has a wiring plug 2 and a mounting block 3. The mounting block 3 has a wiring interface and a camera 4. One end of the mounting block 3 has a slanted groove 8. The top of the threaded hole has a fastening groove. An opening is formed between the fastening groove and the mounting groove, and a fastening plate 5 is mounted on the opening. A push plate 6 is mounted on the top of the fastening plate 5. An elastic component 7 is provided between the push plate 6 and one side of the fastening groove. The fastening plate 5 has beveled edges at both ends, and a threaded post 9 is provided on the threaded hole. A cone 10 is provided between the top of the threaded post 9 and the fastening groove. In this embodiment, the mounting plate 1 is placed on the drone equipment using an installation mechanism. For example, if a fixed-wing or rotary-wing drone is selected, the camera 4 is aligned with the mounting block 3 and inserted into the mounting groove, so that the wiring interface of the mounting block 3 is precisely matched with the wiring plug 2. At this time, the wiring of the camera 4 can be directly connected to the wireless control mechanism wiring. When the wiring interface is matched with the wiring plug 2, the beveled groove 8 of the mounting block 3 is precisely aligned with the opening in the fastening groove. The push plate 6 is elastically supported by the elastic component 7, which allows the push plate 6 to move the fastening plate 5. One end of the fastening plate 5 moves from the assembly slot to the fastening slot. Four cameras 4 can be installed simultaneously through the four assembly slots, each facing one of the four directions, enabling multi-angle data acquisition. The number of cameras 4 can be installed according to the usage requirements. Then, the threaded column 9 is rotated, moving within the threaded hole. The threaded column 9 drives the cone 10 to rotate, causing the cone 10 to contact and align with the inclined edge of one end of the fastening plate 5. The elastic component 7 is compressed and deformed by the push plate 6, causing the other end of the fastening plate 5 to abut against the inclined groove 8 on the mounting block 3, thus locking it in place. Mounting block 3 is mounted on the mounting slot. The fastening plate 5 blocks the opening to prevent dust and impurities from entering the fastening slot. The inclined side and the inclined groove 8 allow the mounting block 3 to be stably and securely installed in the mounting slot, thus enabling the rapid assembly and installation of multiple cameras 4. Then, it can be remotely controlled through a wireless control mechanism. Using the cameras 4, it is convenient to carry out automatic acquisition of multi-view mapping data. When it is necessary to remove the cameras 4, simply rotate the threaded column 9 in the opposite direction to make the cone head 10 leave the inclined side of the fastening plate 5. Then, the elastic support force of the elastic component 7 drives the push plate 6 to reset, thereby making one end of the fastening plate 5 leave the mounting slot, thus making it easy to remove the cameras 4.

[0023] To facilitate remote control, the wireless control mechanism in this solution includes two mounting slots located at the bottom of the mounting plate 1. One mounting slot houses the wireless control module 11, and the other mounting slot houses the energy storage mechanism 12. A sealing cover 13 is provided between the mounting slot and the mounting plate 1, and the sealing cover 13 is connected to the mounting plate 1 by a bolt assembly 14. The energy storage mechanism 12 on the mounting slot can supply power to the camera 4 and the wireless control module 11. The wireless control module 11 facilitates remote control of the structure. The symmetrical arrangement of the two mounting slots ensures overall weight balance.

[0024] To prevent the ground from hitting the camera 4 when the drone lands, the anti-collision mechanism in this solution includes anti-collision posts 15. The anti-collision posts 15 are installed at the bottom of the mounting plate 1. There are four anti-collision posts 15 arranged in an array. The anti-collision posts 15 arranged in an array are higher than the position of the camera 4 and can make contact with the ground first. This can prevent the camera 4 from hitting the ground due to uneven ground during landing or forced landing.

[0025] To further improve the cushioning and anti-collision performance, in this solution, the bottom end of the anti-collision post 15 is provided with a buffer sleeve 16, which can buffer the impact when in contact with the ground.

[0026] To improve the sealing between the mounting block 3 and the assembly groove, in this solution, a sealing strip is provided around the outer perimeter of the mounting block 3. By setting the sealing strip around the perimeter of the mounting block 3, the contact surface between the mounting block 3 and the assembly groove can be stably and reliably sealed.

[0027] The sealing strip and the buffer sleeve 16 can be made of any material. In order to improve the adaptability to extreme temperatures, in this solution, the sealing strip and the buffer sleeve 16 are both made of rubber. The rubber material can be used in both high and low temperature environments.

[0028] To ensure the elastic support of the push plate 6, in this design, the elastic component 7 is an alloy spring. The excellent elastic support force and long service life of the alloy spring ensure the long-term elastic support effect of the push plate 6.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
