Description
Technical field
The utility model relates to air vehicle technique field more particularly to a kind of multiaxis unmanned plane damping devices.
Background technique
In recent years, it with the high speed development of unmanned air vehicle technique, utilizes, has been achieved for excellent in conjunction with the integration of every field
Achievement, wherein unmanned aerial vehicle remote sensing take photo by plane agricultural monitoring and smog forest early period identification fire prevention, the fields such as fire monitoring at
The advantages that this is low, starts with easily, and effect is obvious gradually captures market, and the lifting capacity of unmanned plane directly determines that it can be carried
Holder and video camera type i.e. its shooting ability, multiaxis unmanned plane is because its powerful power and lifting capacity are obviously than it
His machine is more suitable for high definition remote sensing and takes photo by plane, in shooting, if flight shakiness will lead to that composition is unstable so that material cannot be used,
Multiaxis unmanned plane takes advantage in stability, can accomplish to pinpoint shooting in the air, height may be implemented additionally, due to its flexibility
Difficulty with clap flight path.Structural advantage and outstanding flight control system, offline mode based on multiaxis unmanned plane, undoubtedly make it
The only choosing taken photo by plane as high definition remote sensing.The outstanding place adaptability of multiaxis unmanned plane determines its convenience and adaptability.
Fixed-wing, which takes off to land, needs longer openr runway that it is made not adapt to the topography environment of various complexity, so being not appropriate for
Low latitude high definition is done to take photo by plane.Multiaxis unmanned plane is adapted to the topography environment of various complexity, and landing of taking off is all very convenient, does not have substantially
There is the problem of place limitation.
Although multiaxis unmanned plane has the advantages that many, but also have the shortcomings that accordingly, due to high definition remote sensing video pair
The vibration of camera lens is more sensitive, and machine shake is to influence one of the key factor of high definition remote sensing video quality, and multiaxis unmanned plane focus is main
There are two aspects:
One, low frequency and high-frequency vibration caused by motor and propeller high speed rotation are come from, via horn, fuselage, suspension
System, holder are transmitted to video camera, and wherein low-frequency vibration can directly result in film composition shake, and high-frequency vibration can generate picture fruit
Freeze effect, " jelly effect " herein is the video camera using Rolling shutter in shooting high-speed moving object or video camera sheet
Phenomena such as shake for being generated when shooting in the case where high-speed motion, the vibration, distortion, inclination.Most of low and middle-end on the market
All using cmos sensor Rolling shutter, working method is that pixel is allowed to be felt line by line from top to bottom for camera and video camera
It is poor that light produces the small time for exposure, is especially ultimately imaged when shooting swiftly passing object and will result in inclination, abnormal
Become.So the high-frequency vibration bring jelly effect for reducing aircraft is must to solve for many high definition remote sensing are taken photo by plane
One of problem；
Two, one of microseism and focus can be also generated when holder is compensated and executed instruction automatically.
To sum up, since multiaxis unmanned plane structure leads to have a variety of focus, keep its effect in application undesirable, therefore subtract
Shake technology becomes multiaxis unmanned aerial vehicle remote sensing and takes photo by plane the bottleneck of system, and one of urgent problem at present.
In addition, existing multiaxis unmanned plane damping device in use equally there is also some shortcomings it
Place:
One, the integral layout of multiaxis unmanned plane and camera position arrange unreasonable, due to battery is placed on immediately below center of gravity
When holder camera system is suspended on position to the front below center of gravity, machine shake can be enhanced instead by the lever amplification of suspension
The shake up and down of picture, causes material unavailable；
Two, most of holder damping device is all shock-absorbing ball on the market, selects suitable shock-absorbing ball most important, it is whole
The soft tissue shock absorbing device of a shock mitigation system connects unmanned aerial vehicle body and suspension, clouds terrace system, and vibration is by fuselage by subtracting
Shake ball passes to suspension and eventually arrives at video camera；
Third is that the seismism generated for motor and propeller can not accomplish the dispersion cushioning effect of layer-by-layer multistage, lead
It causes the damping effect of unmanned plane general, and then affects the normal operation of video camera.
