Anti-shake measuring device for oblique photography of unmanned aerial vehicle

Abstract

The invention discloses an anti-shake measuring device for oblique photography of an unmanned aerial vehicle, and the device is characterized in that an energy-absorbing anti-shake assembly is used for connecting an oblique photography mechanism to the lower part of a vertical damping assembly, and the energy-absorbing anti-shake assembly can absorb the shaking force from the oblique photography mechanism or / and absorb the oscillation force from the flight of the unmanned aerial vehicle at the same time; the anti-shake effect can be well guaranteed, a first damping arc-shaped body, a second damping arc-shaped body and shear thickening fluid can jointly absorb shaking force from the oblique photography mechanism, damping provided by the device is linearly and gently increased, the anti-shake effect is guaranteed, and in addition, damping exists between an inner cylinder and a middle cylinder, the self-adaptive adjustment can be carried out along with the shaking intensity of the inner cylinder; the space between the outer cylinder and the middle cylinder is filled with the shear thickening agent, the space between the interior of a mounting base and the energy-absorbing anti-shake assembly is filled with the anti-shake vibration reduction cotton, the shear thickening agent and the anti-shake vibration reduction cotton are both used for absorbing oscillating force from the unmanned aerial vehicle, and a better measurement environment can be provided when the unmanned aerial vehicle performs oblique photography.

Description

technical field [0001] The invention relates to the technical field of anti-shake measurement devices, in particular to an anti-shake measurement device for oblique photography of drones. Background technique [0002] Using drones and cameras for oblique photography technology is to collect images from five different angles, including one vertical and four obliques, by carrying multiple sensors on the same flying platform, so as to build the closest to the real 3D model and be able to carry out Geometric measurement, in which five cameras arranged at fixed angles can be used for oblique photography or a single camera can be used for adjustable photography. The single camera needs to use at least two motors when adjusting the shooting, so that the tilt angle and Adjust the direction. Since the shooting equipment is placed under the drone, the vibration generated by the drone during the flight will easily affect the shooting. When adjusting the camera or flying, the shaking of...

[0002] Using drones and cameras for oblique photography technology is to collect images from five different angles, including one vertical and four obliques, by carrying multiple sensors on the same flying platform, so as to build the closest to the real 3D model and be able to carry out Geometric measurement, in which five cameras arranged at fixed angles can be used for oblique photography or a single camera can be used for adjustable photography. The single camera needs to use at least two motors when adjusting the shooting, so that the tilt angle and Adjust the direction. Since the shooting equipment is placed under the UAV, the vibration generated by the UAV during the flight will easily affect the shooting. When adjusting the camera or flying, the shaking of the camera will also affect the UAV. Cause camera shake, affect the stability of shooting
