Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of aerial survey of unmanned aerial vehicle image motion compensation device,
Including imaging device 1, the top of the imaging device 1 is fixedly connected with connecting rod 2, socket in the middle part of the outer wall of the connecting rod 2
There is oscillating bearing 3, the front and back outer wall of the oscillating bearing 3 is welded with support column 4, and the outer end of support column 4 described in two groups is welded
It is connected to support base 5, the left wall of the oscillating bearing 3 is welded with L-type connecting rod 6, and the top of the L-type connecting rod 6 is fixedly mounted
There is electric pushrod 7, the right end of the electric pushrod 7 is fixedly installed with hemispherical permanent magnet 8, the left wall top of the connecting rod 2
It is provided with deep trouth, and is fixedly installed with permanent magnetic plate 9 in deep trouth, the hemispherical permanent magnet 8 is contacted with permanent magnetic plate 9.
Wherein, the bending part of L-type connecting rod 6 is welded with reinforcing rib, improves the intensity of connecting rod 6, improves making for the present apparatus
With the service life, two sides are provided with annular groove up and down for the inner cavity of oscillating bearing 3, the scope of activities of connecting rod 2 are improved, so that imaging device
1 becomes larger with the angle of ground normal, improves the practicability of the present apparatus, and electric pushrod 7 is stepper motor electric pushrod, stepper motor
Stride value is not interfered by extraneous factor, and error does not add up, and control performance is excellent.
Working principle: the present apparatus is connect with unmanned plane, and unmanned plane at the uniform velocity advances, when unmanned plane is being located at point to be captured just
When top, imaging device 1 also is located at the surface of point to be captured, and starting imaging device 1 is imaged, when the moment of imaging needs
Between limited length exposure, the moment of exposure, unmanned plane is not in the surface of point to be captured, while starting imaging device 1
Start electric pushrod 7, the telescopic rod of electric pushrod 7 stretches out, so that the permanent magnetic plate 9 that hemispherical permanent magnet 8 contacts surrounds joint
3 uniform rotation of bearing, the uniform rotation of permanent magnetic plate 9 make connecting rod 2 around 3 uniform rotation of oscillating bearing, connecting rod 2 it is even
