[0026] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 4A multispectral remote sensing device for UAV mapping includes a first steering mechanism 1. A first connecting arm 3 is fixedly connected to the movable end of the first steering mechanism 1. A second steering mechanism 4 is fixedly connected to one end of the first connecting arm 3. Two second connecting arms 7 are fixedly connected to the movable end of the second steering mechanism 4. A housing 8 is installed between the two second connecting arms 7. A connecting socket 9 is integrally connected to one outer surface of the housing 8. A multispectral camera 10 is snapped into the mounting slot of the connecting socket 9. The multispectral camera 10 is electrically connected to a processing unit inside the housing 8 via a quick-connect terminal. A microprocessor 19, a wireless communication module 20, a charging / discharging control module 21, and a battery 22 are installed inside the housing 8. The battery 22 is connected to the charging / discharging control module... Block 21 is electrically connected, the charge / discharge control module 21 is electrically connected to the microprocessor 19, and the microprocessor 19 is electrically connected to the wireless communication module 20. During use, the device can be flexibly and conveniently installed on the bottom of the drone. Then, the multispectral camera 10 is clipped into the slot of the connector 9. After installation, it can be used normally. During the shooting process, if the shooting accuracy of the multispectral camera 10 is not up to standard, the multispectral camera 10 can be flexibly disassembled and replaced, which effectively improves the flexibility of use. During the surveying process, the images captured by the multispectral camera 10 are transmitted to the inside of the microprocessor 19. After being compressed by the microprocessor 19, they are transmitted to the remote receiving end through the wireless communication module 20.

[0028] Reference Figure 1 , Figure 2 , Figure 4The internal structures of the first steering mechanism 1 and the second steering mechanism 4 are identical. The rotation center axis of the first steering mechanism 1 is perpendicular to the rotation center axis of the second steering mechanism 4. The first steering mechanism 1 includes a connecting seat 5 and a movable end 6, which are rotatably connected. A bearing 12 is installed at the rotatable connection between the movable end 6 and the connecting seat 5. A motor 2 and a reduction structure 11 are snapped together inside the connecting seat 5. One end of the rotation shaft of the motor 2 is connected to the input end of the reduction structure 11. The output shaft of the reduction structure 11 is fixedly installed at the central axis position of the movable end 6. A remote control circuit board 18 is installed inside the outer casing 8. The charging and discharging control module 21 is connected to the remote control circuit board. The remote control circuit board 18 is electrically connected to the first steering mechanism 1 and the second steering mechanism 4 respectively. During surveying, a remote control signal can be sent to the remote control circuit board 18 using a remote controller. The remote control circuit board 18 controls the motor 2 inside the first steering mechanism 1 and the second steering mechanism 4 to rotate. Then, under the transmission of the reduction structure 11, it can effectively drive the first connecting arm 3 and the second connecting arm 7 to rotate. Since the rotation center axes of the first steering mechanism 1 and the second steering mechanism 4 are vertically distributed, the multispectral camera 10 can perform multi-directional shooting operations, ensuring that the surveying operation can be carried out effectively. The overall applicability is effectively improved, and the device has a wide range of applications.

[0029] Reference Figure 2 , Figure 3 The reduction structure 11 includes a housing. Inside the housing are a worm gear 13, a worm wheel 14, a linkage shaft 15, a first bevel gear 16, and a second bevel gear 17. One end of the worm gear 13 is connected to one end of the rotating shaft of the motor 2. The worm wheel 14 and the first bevel gear 16 are respectively sleeved and installed at both ends of the linkage shaft 15. The worm gear 13 and the worm wheel 14 are meshed together. The first bevel gear 16 and the second bevel gear 17 are meshed together and perpendicularly distributed. The second bevel gear 17 is sleeved and connected to one end of the output shaft of the reduction structure 11. When the kinetic energy of the motor 2 is transmitted, the motor 2 drives the worm 13 to rotate, the worm 13 drives the worm wheel 14 to rotate, and under the linkage of the linkage shaft 15, the first bevel gear 16 rotates synchronously with the worm wheel 14. Then the first bevel gear 16 drives the second bevel gear 17 to rotate. Since the second bevel gear 17 is sleeved and connected to the outside of one end of the output shaft, it can effectively drive the output shaft to rotate, thereby driving the movable end 6 to rotate, ensuring that the first connecting arm 3 and the second connecting arm 7 can rotate effectively, and at the same time improving the positional stability of each structure.

[0030] Working principle: First, install the device on the bottom of the drone. Then, snap the multispectral camera 10 into the slot of the connector 9. After installation, it can be used normally. During shooting, if the shooting accuracy of the multispectral camera 10 is insufficient, it can be easily disassembled and replaced, effectively improving its flexibility. During surveying, the images captured by the multispectral camera 10 are transmitted to the microprocessor 19. After compression processing by the microprocessor 19, they are transmitted to the remote receiver via the wireless communication module 20. During surveying, the remote controller sends a remote control signal to the remote control circuit board 18, which controls the first steering mechanism 1 and the second steering mechanism 4. The motor 2 in the unit rotates, which drives the worm gear 13 to rotate. The worm gear 13 drives the worm wheel 14 to rotate. Under the linkage of the linkage shaft 15, the first bevel gear 16 rotates synchronously with the worm wheel 14. Then, the first bevel gear 16 drives the second bevel gear 17 to rotate. Since the second bevel gear 17 is sleeved and connected to the outside of one end of the output shaft, it can effectively drive the output shaft to rotate, thereby driving the movable end 6 to rotate. This ensures that the first connecting arm 3 and the second connecting arm 7 can rotate effectively. Since the rotation center axes of the first steering mechanism 1 and the second steering mechanism 4 are vertically distributed, the multispectral camera 10 can perform multi-directional shooting operations, ensuring that the surveying operation can be carried out effectively. The overall applicability is effectively improved, and the device has a wide range of applications.
