UAV's long-focus camera and large-angle head tracking stabilize the gimbal structure

Abstract

The invention discloses a wide-angle head tracking stability increasing holder structure for a long-focus camera of an unmanned aerial vehicle, comprising a ball cover, a camera sliding mechanism, a camera and a sliding ring, wherein the camera comprises a lens and a camera body; the camera is installed on the camera sliding mechanism; the lens of the camera is connected with the sliding ring through the front end of the camera sliding mechanism; the sliding ring is fixedly installed at the front part of the ball cover; and the rear end of the camera sliding mechanism is connected with the rear part of the ball cover. According to the invention, because the camera body moves but the lens does not move in a camera zooming process, an accurate and clear field image can be acquired, and the photographing effect is good. Meanwhile, a wide-angle direction motor and a pitching motor can drive the ball cover to rotate, and a horizontal stability increasing motor can drive the camera installed in the camera sliding mechanism to swing on a horizontal plane, thereby increasing the stability of the camera; and the camera has the advantages of good stability, reliable action and capability of swinging in multiple angles.

Description

technical field [0001] The invention relates to a camera mounting device, in particular to a large-angle head tracking and stabilization platform structure of a long focal length camera of an unmanned aerial vehicle. Background technique [0002] The Cloud Terrace is a supporting device for installing and fixing cameras and video cameras. UAV aerial photography is to use unmanned aerial vehicles as the air platform, and use airborne remote sensing equipment, such as high-resolution CCD digital cameras, light optical cameras, infrared scanners, laser scanners, magnetic detectors, etc. to obtain information. The computer processes the image information and makes an image according to certain precision requirements. The whole system has outstanding features in terms of design and optimal combination. It is a new application technology that integrates high-altitude shooting, remote control, telemetry technology, microwave transmission of video images and computer image informat...

Problems solved by technology

When using a traditional long-focus camera for aerial photography, in order to obtain accurate and clear on-site images, the long-focus camera must focus. Since the long-focus camera is installed in the dome cover on the gimbal, the lens of the camera needs to move back and forth to focus. , when the lens retracts, there is a certain distance between the lens and the dome cover, and the shooting range needs the material of the dome cover to meet the optical requirements to obtain accurate and clear on-site images. Then, the material cost of the dome cover is very high, and, from The sunlight incident on the side of the dome cover will make the image flood and affect the photographic quality

At the same time, during the flight of the drone, in order to find the direction and aim at the target, it needs to fly sideways and the gimbal needs to swing at a large angle of 360 degrees. The existing gimbal connection method cannot meet the requirements of obtaining accurate and clear scene image request
