Three-degree-of-freedom aerial photographic head with stable inertia

Abstract

The invention discloses a three-degree-of-freedom aerial photographic head with the stable inertia, which comprises a stabilizer, a transmission device and a camera. The three-degree-of-freedom aerial photographic head with the stable inertia adopts a main principle that a mechanical gyro with the considerable inertia realizes stable shooting. A head bracket is connected with a horizontal rotating rack; the horizontal rotating rack is connected with the mechanical gyro to form the stabilizer; and the stabilizer is connected with the camera through the transmission device, so the synchronous movement of the gyro and the camera in the vertical direction can be realized and the stable shooting of the camera can be realized by the stability of the gyro. The three-degree-of-freedom aerial photographic head with the stable inertia can eliminate the influence of the high-frequency and low-frequency vibration of a plane on the aerial photographic images and the problem of image inclination which is caused by the inclination of the plane, can photograph very clear and stable images without any chattering removal treatment and has good application effects in aspects of line detection, fixed-point monitoring, aerial photograph and the like. The three-degree-of-freedom aerial photographic head with the stable inertia has novel design and strong stability and can meet requirements on most high-quality aerial photographs.

Description

technical field [0001] The present invention relates to a stable cloud platform for aerial photography, in particular to a controllable three-degree-of-freedom inertia used for carrying a video camera or a camera to achieve stable photography, which is used in aerial photography and monitoring of an unmanned helicopter Stabilize the gimbal for aerial photography. Background technique [0002] UAV has the characteristics of small size, light weight, low cost, flexible operation and high safety, and can be widely used in aerial photography, monitoring, search and rescue, resource exploration and other fields. Due to the high-frequency vibration and low-frequency jitter of the drone itself, it is necessary to configure an aerial photography stabilization platform to carry cameras and cameras to achieve stable shooting. Most of the currently used aerial photography stabilization platforms use electronic equipment to detect the attitude change of the camera or camera, and contro...
