Three-axis photoelectric pod

Abstract

The invention discloses a three-axis photoelectric pod which comprises a photoelectric imaging load and a rolling assembly, wherein the photoelectric imaging load is installed in the rolling assembly; a pitching assembly, wherein a closed mounting cavity is formed in the pitching assembly, and the rolling assembly is mounted in the mounting cavity; and an orientation assembly, which is connected with external required equipment and is provided with a mounting groove, wherein the two sides of the pitching assembly are connected to the inner side wall of the mounting groove. The device is reasonable in design and ingenious in structure. The multi-directional movement mechanism is used in a three-axis pod of flight equipment, and through reasonable design of a pitching assembly, a rolling assembly and an orientation assembly, multi-directional movement of a photoelectric imaging load is achieved. The pitching assembly and the rolling assembly are both supported at the two ends, and the product rigidity is high; the structure is small in deformation under impact and vibration environment conditions, the pod stability precision is high, and the imaging quality is good.

Description

technical field [0001] The invention relates to the technical fields of unmanned aerial vehicle inspection, aerial photography, monitoring, survey, etc., in particular to a three-axis photoelectric pod. Background technique [0002] The change of pitch, yaw and roll attitude during the flight of the helicopter will cause the photoelectric imaging load to generate image rotation during the imaging process. In order to eliminate the image rotation and improve the imaging quality, the photoelectric pod can adopt the structure of three axes and three frames. The composite motion of the pitch axis, roll axis, and pitch axis compensates the image rotation caused by the attitude change of the helicopter. [0003] The existing three-axis pods are mostly used in UAVs, and the azimuth frame often adopts a single-sided cantilever structure in order to reduce the weight. For example, in the three-axis pod disclosed by the patents whose publication numbers are CN211685663U and CN2089867...

Problems solved by technology

[0004] However, the roll frame in the prior art is supported by a unilateral cantilever, and the shape of the pod is asymmetrical, and the transition of the joints of each component is not smooth. , Under vibrational environmental conditions, it is easy to produce large deformation, which reduces the stability accuracy, imaging quality and reliability of the pod
