A multi-lens aerial photography stabilization platform

Abstract

The invention relates to a multi-lens aerial camera shooting stabilized platform. The multi-lens aerial camera shooting stabilized platform comprises a suspension arm mechanism, a camera shooting platform, cameras arranged inside the camera shooting platform, and a gyroscope. The suspension arm mechanism comprises a first rotating assembly, and the suspension arm mechanism is connected with the camera shooting platform through the first rotating assembly to control the camera shooting platform to rotate in a first rotating plane which is perpendicular to the horizontal plane. A second rotating assembly is arranged inside the camera shooting platform to control the camera shooting platform to rotate in a second rotating plane which is perpendicular to the horizontal plane and the first rotating plane at the same time. The gyroscope is arranged on the camera shooting platform and is electrically connected with the first rotating assembly and the second rotating assembly to control the first rotating assembly and the second rotating assembly to work. Compared with the prior art, through the multi-lens aerial camera shooting stabilized platform, the gyroscope, the first rotating assembly and the second rotating assembly are used, the camera shooting platform can be adjusted in a two-dimension plane, the boresight stability of the cameras is promoted, and vibration is prevented.

Description

technical field [0001] The invention relates to a multi-lens aerial photography stabilization platform, in particular to a stabilization platform suitable for small low-altitude remote sensing drones. Background technique [0002] UAV low-altitude remote sensing system is developing into the special field of photogrammetry and stereo mapping on the basis of realizing image map production. According to the aerial photogrammetry specification, the UAV aerial photography system used for photogrammetry has strict quantitative requirements on the attitude stability of the payload. However, the aircraft will be affected by body vibration and stray airflow in the air during aerial photography, and the payload will change the photographic attitude accordingly, causing serious problems such as aerial photography loopholes and too small intersection angles in photogrammetry. [0003] In view of the above problems, in the prior art, the stabilization control of the payload of the UAV ...
