The invention discloses a pendular photoelectric stabilizing device for aerial photography and relates to the technical field of auxiliary shooting of unmanned aerial vehicle carrying platforms. An external shock absorbing mechanism is connected to an aerial carrier through a connecting plate, an external frame system is connected to the external shock absorbing mechanism through an external azimuth axis, an internal frame system is connected to the external frame system in a screw fastening manner, and an insulating interlayer and an electromagnetic shielding film are arranged between the external frame system and the internal frame system. The pendular photoelectric stabilizing device for aerial photography has the advantages that the external shock absorbing mechanism can isolate vibration generated by the aerial carrier and other natural environments effectively through an electromagnetic shock absorbing device; the external frame system can compensate the pose of the photoelectricstabilizing device; the internal frame system carries out scanning imaging large in range, wide in coverage and high in quality by rotating an oscillating mirror; the insulating interlayer is used for maintaining the temperature of the internal frame system to inhibit influence of temperature change on surface precision of a reflector; and the electromagnetic shielding film can cut down influenceof electromagnetic interference generated by the natural environments and the photoelectric stabilizing device on the internal frame system.
Description
technical field [0001] The invention relates to the technical field of auxiliary photography on a UAV-mounted platform, in particular to a swing-sweep photoelectric stabilization device for aerial photography. Background technique [0002] With the continuous development of science and technology, aerial photography drones have been rising in recent years, and the stability of the airborne platform has also attracted people's attention. The airborne platform is a supporting device for installing and fixing camera equipment, and is used to control cameras or other equipment. The rotation direction of the drone, the complex working environment of the UAV has a great impact on the stability of the airborne equipment, resulting in a large vibration during the flight of the UAV, which affects the quality of aerial photography. Therefore, the airborne platform reduces vibration and The ability to perform vibration compensation is particularly important. [0003] During the flight...
