Description

Technical Field

[0001] The utility model relates to the technical field of aerial photography and mapping equipment, in particular to an aerial photography and mapping platform. Background Art

[0002] With the technological advancement of multi-rotor drones, more and more aerial photogrammetry is being carried out by drones carrying airborne equipment over the ground because they are not restricted by terrain. They are used in remote sensing mapping, disaster relief and other occasions where geographical information needs to be collected through photogrammetry. When installing and using, a gimbal is fixed on the drone, and the airborne equipment is installed on the gimbal. The gimbal has multiple degrees of freedom to adjust the azimuth angle of the airborne equipment.

[0003] Common airborne devices include optical cameras, laser radars, infrared cameras, etc. Some of these airborne devices are integrated in a housing (i.e., these airborne devices are installed on the gimbal through a connector on the top of the housing), while others are not integrated (i.e., these airborne devices belong to different housings and each needs to be installed separately). In some cases, aerial photogrammetry requires multiple airborne devices to work together to collect different types of data, but most gimbals only have one interface. When different types of data need to be collected, for airborne devices that are not integrated, since only one type of airborne device can be carried by the drone for flight at a time, the drone needs to perform multiple repeated flights to collect the required data, which reduces work efficiency and is inconvenient for users.
