Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle gimbals, and in particular to a three-axis stable gimbal suitable for unmanned aerial vehicle aerial photography and capable of carrying a dual-source remote sensing sensor. Background Art

[0002] At present, drone technology is developing rapidly, and drone aerial photography has been widely used in many fields. As one of the key technologies for drones to realize aerial photography and monitoring functions, the gimbal not only ensures the stability of aerial photography operations, but also improves the accuracy of data collection. The working principle of the gimbal is to offset the vibration and swing caused by movement through the rotation of a single or multiple motors, thereby maintaining the stability of the equipment carried. Depending on the model of the drone and the equipment carried, the structure and appearance of the gimbal vary.

[0003] With the increasing demand for remote sensing observation of urban thermal environment, single-source remote sensing has gradually failed to meet the requirements of engineering and scientific research due to its single data type and small amount of data, and dual-source remote sensing observation has become an urgent need. The use of drones equipped with customized dual-source remote sensing sensors is an important innovative technology for urban thermal environment observation. At present, the three-axis gimbals commonly seen on the market are mainly used to carry matching single-type sensors. Although there are universal gimbals that can carry multiple types of equipment, when two different types of sensors need to be carried at the same time, the universal gimbals are no longer applicable. For customized dual-source remote sensing sensors, especially when the requirements for synchronous adjustment of observation angles need to be met, there is no suitable gimbal on the market.

[0004] In view of this, there is a need for a three-axis stabilized gimbal for UAVs, which can carry dual-source remote sensing sensors at the same time and ensure that the sensor observation angle is kept stable during aerial photography, enrich the remote sensing data type and improve the accuracy of the data.
