Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping technology, and in particular to a surveying and mapping unmanned aerial vehicle for surveying and mapping geographic information. Background Art

[0002] Drone mapping is a technical method that uses drones equipped with sensors to obtain aerial data to achieve rapid, high-precision mapping, three-dimensional modeling and data processing of ground objects. In practical applications, drone mapping technology can complete land surveying, building surveying, investigation and evaluation, monitoring and management, three-dimensional modeling and other operations. For example, in the field of land surveying, drone mapping can be used for dynamic monitoring and investigation of land resources, updating of land use and coverage maps, etc.; in environmental monitoring, drone mapping can accurately obtain high-resolution aerial images and timely monitor environmental pollution and other problems; in agricultural and forestry applications, drone mapping can be used for farmland navigation, land rights confirmation, farmland plant protection operations, etc., to improve work efficiency and accuracy.

[0003] The principle of drone mapping is mainly based on the aerial photography equipment carried by drones, such as cameras, laser radars, etc., for aerial photography and data collection. In drones that shoot with cameras, the lens is easily contaminated due to the large amount of flying dust generated near the ground during takeoff, thus affecting the photography after takeoff; in addition, when drones are operating at high altitudes, they are affected by crosswinds, and the camera position is prone to vibration, affecting the photography effect.

DETAILED DESCRIPTION

[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0018] like Figure 1-Figure 8 A surveying and mapping UAV for surveying and mapping geographic information shown in the figure comprises a frame 1, a lifting mechanism is arranged at the corner of the frame 1, a processing module is fixedly mounted on the upper surface of the frame 1, a camera 2 is mounted on the lower surface of the frame 1, baffles 3 are fixedly mounted on the lower surface of the frame 1 near the front and rear edges, two symmetrical arc plates 4 are arranged near the two sides of the lower surface of the frame 1, and a driving mechanism is arranged on the upper surface of the arc plate 4; The lower edges of the arc-shaped plates 4 on both sides are close to each other and cover the bottom of the camera 2, which can protect against dust.

[0019] The arc plate 4 is pulled by the driving mechanism to block the two sides of the camera 2, and the state is as follows: Figure 6 As shown, at this time, the shooting of the camera 2 may not be affected, and at the same time, the camera 2 is protected and the impact of the crosswind on the camera 2 is reduced.

[0020] like Figure 1 As shown, the lifting mechanism includes a connecting frame 13 fixedly installed at the corner of the frame 1, a motor 14 is fixedly installed at the end of the connecting frame 13, a fan blade 15 is fixedly installed on the output shaft of the motor 14, and the motor 14 drives the fan blade 15 to rotate, thereby assisting the drone to take off.

[0021] like Figure 4 , Figure 8 As shown, the processing module includes a circuit board 18 fixedly mounted on the upper surface of the frame 1, and a surveying and mapping module 22, a positioning module 23, a data storage device 24, a first data transceiver module 25 and a controller 21 are arranged on the surface of the circuit board 18. The controller 21 is electrically connected to the surveying and mapping module 22, the positioning module 23, the data storage device 24 and the first data transceiver module 25 through the circuit board 18; It also includes a ground signal base station 26, which is provided with a second data transceiver module 27 and an image processing module 28 which are electrically connected to each other. The image processing module 28 is electrically connected to a data storage library 29, and the data storage library 29 is used to store valid information extracted from the image.

[0022] The controller 21 is also called a central processing unit, which is used to control the mapping module 22, the positioning module 23, the data storage 24 and the first data transceiver module 25. The positioning module 23 is used to determine the position signal, thereby cooperating with the ground signal base station 26 to control the drone.

[0023] like Figure 7 As shown, a wire passing port 19 is formed through the upper surface of the frame 1, and the port of the camera 2 is electrically connected to the circuit board 18 through wires. After the wires pass through the wire passing port 19, they are connected to the interface on the side of the circuit board 18 to complete the electrical connection between the two.

[0024] like Figure 1 As shown, a cover 16 is fixedly mounted on the upper edge of the frame 1, and a battery 17 is fixedly mounted on the upper surface of the cover 16. The battery 17 can be a lithium battery, which has high energy and is relatively light.

[0025] like Figure 3 , Figure 4 , Figure 5As shown, the driving mechanism includes a telescopic rod 5 rotatably connected to the upper surface of the arc plate 4, the upper end of the telescopic rod 5 is fixedly passed through the upper surface of the frame 1, two connecting shafts 11 are fixedly installed between the front and rear baffles 3, the connecting shafts 11 are located on both sides below the camera 2, and the upper surface of the arc plate 4 is fixedly connected with spring pieces 8 near the front and rear edges, respectively, and the upper ends of the spring pieces 8 are fixedly connected to the lower surface of the frame 1, and the lower surface of the frame 1 is provided with through openings 9 near both sides, and a barrel cover 10 is fixedly installed at the upper end of the through opening 9. The design of the through opening 9 and the barrel cover 10 provides space for the arc plate 4 to rise, and at the same time, it is relatively closed to prevent dust from entering the surface of the circuit board 18.

[0026] The outer surface of the connecting shaft 11 is rotatably sleeved with a roller 12 for making smooth contact with the surface of the arc-shaped plate 4 to prevent mutual scratching.

[0027] A rotating shaft 6 is fixedly connected to the lower end of the telescopic rod 5, and two connecting seats 7 are fixedly provided on the upper surface of the arc plate 4. The connecting seats 7 are arranged at the front and rear sides of the lower end of the telescopic rod 5, and the connecting seats 7 are rotatably matched with the rotating shaft 6. This part is the specific rotational connection method between the telescopic rod 5 and the arc plate 4.

[0028] When the drone takes off, the motor 14 drives the fan blades 15 to rotate, and the airflow blowing toward the ground turns up, and part of it blows toward the bottom of the arc plate 4, thereby assisting the drone to take off.

[0029] When the fan blades 15 blow air to the ground, the dust blown up will be blocked by the arc plate 4, and cooperate with the baffle plate 3 to block the dust coming from the front and rear directions to prevent the camera 2 from being dirty.

[0030] After the UAV rises to a high altitude, the arc plate 4 can be lifted up by controlling the telescopic rod 5 to contract, and then blocked by the roller 12. At the same time, the arc plate 4 will rotate around the rotating shaft 6. After continuing to rise, the upper end of the arc plate 4 will pass through the inner side of the through hole 9 and reach the tube cover 10. Figure 6 As shown, after the arc plate 4 is rotated and erected, it can block the cross wind from the side of the camera 2, and cooperate with the front and rear baffles 3 to block the cross wind from the front and rear directions, ensuring the stability of the camera 2 during shooting.

[0031] After the camera 2 takes a picture, the original image data is collected by the surveying and mapping module 22, and the data is imported into the data storage 24. Then, the data is transmitted between the first data transceiver module 25 and the second data transceiver module 27, so that the ground signal base station 26 receives the data. The image data is processed by the image processing module 28 to extract useful information from the original image to meet the needs of measurement and mapping.
