Unmanned aerial vehicle onboard cradle head stability augmentation system suitable for panoramic video shooting

Abstract

An unmanned aerial vehicle onboard cradle head stability augmentation system suitable for panoramic video shooting comprises a fixedly-connecting mechanism, a pitching adjusting mechanism and a rolling adjusting mechanism. The fixedly-connecting mechanism comprises a cradle head connecting base, and the cradle head connecting base is provided with a carrying track for carrying the rolling adjusting mechanism. The rolling adjusting mechanism comprises a supporting frame, a rolling drive source and a rolling transmission mechanism. The pitching adjusting mechanism is installed on the supportingframe of the rolling adjusting mechanism and comprises a camera installation platform, a left side pitching adjusting unit and a right side pitching adjusting unit, and the left side pitching adjusting unit and the right side pitching adjusting unit each comprise a pitching drive source and a pitching transmission mechanism. The camera installation platform is installed between the output ends ofthe two pitching transmission mechanisms, and an aerial photography camera is installed below the camera installation platform in a hoisting mode. A cradle head can meet the requirement for the shooting stability characteristic under a panoramic aerial photography condition, and the problems that pictures are not synchronous and the view angle is blocked when an existing cradle head shoots a panoramic video are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle photography and airborne pan-tilt, and is a stabilizing pan-tilt suitable for panoramic video shooting in the process of aerial photography. Background technique [0002] The gimbal is a stabilization device composed of two or more motors, and the camera has three degrees of freedom in the air, including pitch, roll and lateral motion. The gimbal used in the aerial photography system can automatically control its rotation and moving direction through the control system, so as to keep the angle between the camera equipment and the base vector in the space coordinate system not relative to each other when the flight state of the UAV changes. Change the role to get higher quality shooting content. [0003] Airborne gimbals are generally equipped with a single-lens camera. During the normal photography process, the content of the material obtained at the same time is limited, only the...

AI Technical Summary

Problems solved by technology

[0003] Airborne gimbals are generally equipped with a single-lens camera. During the normal photography process, the content of the material obtained at the same time is limited, only the image directly in front of the lens, but the state of the scene in other directions cannot be obtained, that is, It is impossible to achieve 360° viewfinder shooting in space. Even if a single-lens camera can take 360° shots by controlling the rotation of the gimbal to obtain panoramic photos, it is still necessary to keep the camera equipment in a relatively static state during video recording, and it is impossible to obtain omnidirectional views. The real-time performance of the video information is not as direct as direct panoramic shooting, especially when video shooting is required, the effect of directly using the panoramic camera for model reconstruction is obviously much better

[0004] The aerial photography gimbals currently on the market are not compatible with multi-lens panoramic shooting systems, so in order to obtain high-quality panoramic images and video materials, another gimbal system specially adapted to multi-lens panoramic cameras is required
