The invention discloses a kind of unmanned plane imaging optical system, including body, and it is carried on the imaging device on the body, the imaging device includes housing and camera lens, controller is provided with the body, processor and memory are provided with the housing, imaging sensor is provided with the camera lens, it is characterized in that, described image sensor and the memory are connected with the processor or controller communication, wherein, the camera lens is fish eye lens, by the first lens, second lens, 3rd lens, 4th lens, 5th lens and the 6th lens composition, fish-eye structure composition can realize miniaturization, in addition, because each lens are all glass spheric glass, so multiplying power correction can be realized easily and suitable for different temperature occasions.
Description
Technical field
The present invention relates to optical system, more particularly to a kind of unmanned plane imaging optical system.
Background technology
In recent years, unmanned air vehicle technique obtains fast-developing, and in the purposes of unmanned plane, it is that it is mainly used to take pictures and record a video
One of way.For being respectively provided with flexible connection head on the unmanned plane taken photo by plane, driving equipment, driving equipment are typically provided with head
Imaging device is driven, so realizes shooting of the imaging device to the scene of different angle.With the development of optical lens technology, though
So fish-eye structure type is constantly improved, but basic structure does not change, main to include preceding group lens with after
Group lens, preceding group of lens are the meniscus shaped lens group with very big negative power, to realize that the angle of visual field is more than or equal to 180 °
Optical property, it is rear to organize the lens group that lens are the positive light coke with complication, to improve relative aperture and aberration correction.
Fish-eye number of lenses of the prior art is more, causes whole fish-eye volume larger, and cost is higher, processing
Difficulty is big.
The content of the invention
The deficiency for more than, it is an object of the invention to propose a kind of a kind of miniaturization of offer, easily realize multiplying power school
Positive fish eye lens.
The present invention is achieved through the following technical solutions：
A kind of unmanned plane imaging optical system, it is characterised in that：Set including body and the imaging being carried on the body
Standby, the imaging device includes housing and camera lens, and controller is provided with the body, be provided with the housing processor and
Memory, be provided with imaging sensor on the camera lens, it is characterised in that described image sensor and the memory with it is described
Processor or controller communication connection；The camera lens is fish eye lens, including close thing side and the first lens with negative power
Group, close to imaging surface and there is the second lens group of positive light coke, and located at first lens group and second lens group
Between diaphragm, it is characterised in that first lens group from thing side to imaging surface successively include there is negative power and concave surface
Towards the lens of curved month type first, the second lens and the 3rd lens of imaging surface；Second lens group from thing side to imaging surface according to
It is secondary including the lens of biconvex the 4th with positive light coke, the 5th lens and curved month type with negative power and concave surface towards thing side
6th lens, the 5th lens and the 6th lens glue are combined into the lens element with positive light coke；Described first is saturating
Mirror, second lens, the 3rd lens, the 4th lens, the 5th lens and the 6th lens are all glass
Spheric glass, and the optical centre of each lens is located along the same line.
Preferably, fish-eye optics overall length is 17.1mm.
Preferably, fish-eye F-number is 2.0.
Preferably, the fish-eye angle of visual field is 210 °.
The beneficial effects of the present invention are fish-eye structure composition can realize miniaturization, further, since each
Mirror is all glass spheric glass, so multiplying power correction can be realized easily and suitable for different humiture occasions, described in extension
Fish-eye service life, produced suitable for batch machining, reduce cost.
Brief description of the drawings
Fig. 1 is fish-eye cross section structure schematic diagram in the embodiment of the present invention.
Main element symbol description：
First lens group 10, the first lens 11, the second lens 12, the 3rd lens 13, diaphragm 30, the second lens group 20, the 4th is saturating
Mirror 21, the 5th lens 22, the 6th lens 23.
Embodiment
The following example is being explained further and supplementing to the present invention, and the present invention is not limited in any way.
A kind of unmanned plane imaging optical system, including body and the imaging device that is carried on the body, it is described into
Picture equipment includes housing and camera lens, is provided with controller in the body, processor and memory, institute are provided with the housing
State and imaging sensor be provided with camera lens, it is characterised in that described image sensor and the memory and the processor or
Controller communication connects.The camera lens is fish eye lens.
As shown in figure 1, a kind of fish eye lens provided in one embodiment of the invention, including close to thing side and with negative light focus
First lens group of degree, close to imaging surface and there is the second lens group of positive light coke, and located at first lens group and institute
The diaphragm between the second lens group is stated, wherein, first lens group includes having negative power successively from thing side to imaging surface
And concave surface is towards the lens of curved month type first, the second lens and the 3rd lens of imaging surface；Second lens group from thing side into
Image planes include the lens of biconvex the 4th with positive light coke, the 5th lens and with negative power and concave surface towards thing side successively
The lens of curved month type the 6th, the 5th lens and the 6th lens glue are combined into the lens element with positive light coke；It is described
First lens, second lens, the 3rd lens, the 4th lens, the 5th lens and the 6th lens are all
Optical centre for glass spheric glass, and each lens is located along the same line.The fish eye lens is also included located at described
Two blocks of plate glass between second lens group and imaging surface, two blocks of plate glass be arranged in parallel.
Fish-eye optics overall length is 17.1mm, and F-number 2.0, the angle of visual field is 210 °
The beneficial effects of the present invention are fish-eye structure composition can realize miniaturization, further, since each lens are all
For glass spheric glass, so multiplying power correction can be realized easily and suitable for different humiture occasions, extend the flake
