Description

Aircraft two degrees of freedom surely looks like The Cloud Terrace

Technical field

The present invention relates to the electronic equipment field, particularly relate to a kind of aircraft two degrees of freedom and surely look like The Cloud Terrace.

Background technology

Utilize the aircraft images acquired very general, but at present during images acquired, the staff just simply is fixed on image collecting device on the aircraft, aircraft image acquisition in flight course is put and can be carried out ground, the continuous acquisition work of image all around, but the flight of aircraft is not pulsation-free always, and roll takes place sometimes, pitching takes place sometimes, so along with the action of aircraft, along with rocking, it is not very high taking the picture quality of coming out to camera lens yet.

The utility model content

The utility model is at the defective of above-mentioned prior art, provide a kind of aircraft two degrees of freedom surely to look like The Cloud Terrace, it is loaded on the aircraft, can accomplish that aircraft rocks, and pick-up lens does not rock thereupon, thereby has stablely, follows the tracks of, the effect of lock image also can be made fine setting to the shake of the vehicle.

Aircraft two degrees of freedom surely looks like The Cloud Terrace, comprise a detecting device, a movement device and an image collecting device, described detecting device is electrically connected with described movement device, described movement device is captiveed joint with image collecting device, described detecting device is used for the pendulum angle of sense aircraft, and described movement device is used for the testing result of detecting device is done the corresponding action of adjusting.

Described detecting device comprises a roll gyroscope and a pitch gyroscope, the angle of described roll gyroscope sense aircraft roll, the angle of described pitch gyroscope sense aircraft pitching.

Described movement device comprises a roll steering wheel and a pitch-control motor, and described roll steering wheel is electrically connected with the roll gyroscope, and the angle of roll is made corresponding adjustment; Described pitch-control motor is electrically connected with pitch gyroscope, and the angle of pitching is made corresponding adjustment, and described detecting device also comprises a support, and described roll steering wheel and a pitch-control motor are separately fixed on the described support and setting in vertical direction.

Described image collector is changed to pick up camera.

Described pitch-control motor is captiveed joint with pick up camera, and described pitch-control motor is installed in pitching place of support, and described roll steering wheel is fixed on roll place of support.

Described support is an aluminium alloy post.

Aircraft two degrees of freedom is a system that realizes the images acquired function on aircraft as The Cloud Terrace surely, the image stabilization of the utility model for realizing collecting, a detecting device and a movement device have been adopted, detecting device is used for the motion conditions of sense aircraft, it is fed back to movement device, make the corresponding action adjustment, move and the motionless purpose of image thereby reach aircraft by movement device, make and take the image stabilization that obtains, clear.

A roll gyroscope and a pitch gyroscope have been comprised in the detecting device, the roll gyroscope detects the roll angle of flight, pitch gyroscope detects the luffing angle of flight, comprise a roll steering wheel and a pitch-control motor in the movement device, the roll steering wheel is made compensation to the roll angle, pitch-control motor is made compensation to luffing angle, thereby realizes the function of the steady picture of two degrees of freedom.

The utility model has adopted a support, and pitch-control motor is captiveed joint with pick up camera, and is rack-mount, and the pitch-control motor action drives the pick up camera action, thereby makes pick up camera obtain the compensation of luffing angle; The roll steering wheel is fixedly mounted on roll place of support, and the action of roll steering wheel drives the support action, makes pick up camera also obtain the compensation of roll angle, has realized that therefore aircraft is moving, and the motionless purpose of camera.The preferred aluminum alloy materials of support, the one, because it punches easily other parts are fixed, the while light weight, it is too big to be unlikely the load increase that makes aircraft.

Utilize the aircraft of RC Goblin model plane as experiment usefulness, the utility model aircraft two degrees of freedom surely is fixed on the helicopter as The Cloud Terrace, by remote controller control helicopter flight, the distant bar of remote controller by the control steering wheel manually obtains to enter the steady picture of locking state again behind the image then, the image of camera picked-up is transferred to video signal receiver, insert computer through video-signal converting apparatus again, just can clearly see the image of pick up camera in the helicopter photographs, make helicopter make exercises by the aircraft remote controller, can see that from computer unsharp phenomenon does not take place image.Because The Cloud Terrace has two degrees of freedom, the scope that artificially obtains image is very big, and is also very flexible.Can also after choosing image by hand, enter the steady picture of locking state again.

The specific embodiment

Embodiment

Fig. 1 is connected the work scheme drawing for the utility model aircraft two degrees of freedom surely looks like The Cloud Terrace with external piece.Aircraft two degrees of freedom surely looks like The Cloud Terrace 1 by detecting device 11, and movement device 12 and image collecting device 13 are formed, and movement device 12 and image collecting device 13 are installed on the aluminium alloy post 14.Movement device 12 is electrically connected with detecting device 11, and detecting device 11 is used to detect the pendulum angle of helicopter, and movement device 12 is used for the testing result of detecting device 11 is done the corresponding action of adjusting.Detecting device comprises a roll gyroscope 111 and a pitch gyroscope 112, the roll gyroscope is installed in roll place of helicopter, be used to detect the angle of helicopter roll, pitch gyroscope 112 is installed in pitching place of helicopter, is used for the angle of sense aircraft pitching.

Movement device 12 comprises a roll steering wheel 121 and a pitch-control motor 122, and roll steering wheel 121 is electrically connected with roll gyroscope 111, and the angle of roll is made corresponding adjustment; Pitch-control motor 122 is electrically connected with pitch gyroscope 112, and the angle of pitching is made corresponding adjustment.Image collector is changed to pick up camera 131, and pitch-control motor 122 is captiveed joint with pick up camera 131 and is fixedly mounted on pitching place of aluminium alloy post 14, and roll steering wheel 121 is fixed on roll place of aluminium alloy post 14.

Aircraft two degrees of freedom surely is installed on the helicopter as The Cloud Terrace 1, with roll gyroscope 111 and pitch gyroscope 112, roll steering wheel 121 is connected with helicopter power supply 2 with pitch-control motor 122, the action of control helicopter remote controller RC Goblin, and then manually obtain to enter again behind the image the steady picture of locking state by the distant bar of remote controller of control steering wheel, the picture signal of image collecting device 13 picked-ups passes to video signal receiver 3, be connected to computer 5 through video-signal converting apparatus 4 again, just can have seen the image of collection.Because reverse respectively control roll steering wheel 121 in back and pitch-control motor 122 are measured in rocking of

roll gyroscope

111 and 112 pairs of helicopters of pitch gyroscope, make it to the corresponding angle of pick up camera 131 compensation, it is constant that thereby the influence that pick up camera can not be rocked by helicopter, camera can keep setting attitude.Can see that from computer after the rocking of helicopter, image is obviously swing and unsharp phenomenon not.Because two degrees of freedom is arranged, the scope that artificially obtains image is also very big, and angle that can very flexible adjustment shooting can also enter lock onto target again behind the image and surely looks like state by manual choosing.
