Camera accessories include at least two fish eye lenses, fuselage and the first data/power interface；Each fish-eye center line position
In in same plane and being uniformly distributed on the fuselage, each fish-eye shooting angle sum is more than 360 degree；It is described
First data/power interface is located on the fuselage, for connection universal equipment.The advantages of device is can be with virtual cloud
The mode of platform is imaged, but its shortcoming is also what be can not be ignored, when two fish eye lenses carry out picture fitting and montage, its
Low precision.
Traditional panorama camera device fish eye lens field of view angle is smaller, installation accuracy is low, the light using two internal reflections
Component is reflected, the picture deformation that optical sensor is collected into is big, in handling to the image collected by optical sensor
When, the problem of due to picture precision, its intractability is big.
The content of the invention
It is an object of the invention to provide a kind of shooting dress that can be effectively improved picture authenticity, improve picture splicing precision
Put, while present invention also offers the processing method of the camera device.
The concrete scheme of the present invention is as follows：A kind of camera device, including sensor, light reflection element, two fish eye lenses,
Described sensor is connected with image-signal processor, and described fish-eye field of view angle is described more than or equal to 220 °
Light reflection element is provided with two external reflectance faces coordinated respectively with fish eye lens, described fish eye lens and corresponding external reflectance
The angle in face is 45 °, and the angle in described sensor and external reflectance face is 45 °；Two described fish-eye axle center deviations
Less than 2.
In above-mentioned camera device, in addition to cylinder, described fish eye lens are fixed on cylinder both ends, described sensing
Device is arranged between two fish eye lenses, and described sensor is arranged on the underface of sensor.
In above-mentioned camera device, described fish-eye distortion parameter is linear distortion.
In above-mentioned camera device, the focal length of described fish eye lens to sensor is more than 8mm.
In above-mentioned camera device, described described cylinder and light reflection element are obtained by being integrally formed casting.
Compared with prior art, its advantage is the present invention：
The present invention passes through specific fish-eye selection, the selection of specific light reflection element, and specific flake
The selection of the installation accuracy of camera lens can improve picture authenticity, improve picture splicing precision.
Specifically, the present invention can overcome traditional internal reflection side using the light reflection element with two external reflectance faces
The formula requirement unified to optics refractive index, cuts or is molded by two external reflectance faces on one piece of light reflection element, only
Machining accuracy is wanted to reach design requirement, two light reflection element cans are very accurate, the reflection without deformation.
Meanwhile fish-eye field of view angle is also increased to 220 ° by the present invention, this avoid caused by edge deformation
The problem of montage degree of accuracy is low.
Meanwhile the present invention also limit the axle center deviation between two fish eye lenses, so when image enters on a sensor
When row display, its concentricity is high, using the montage to head portrait, improves the accuracy of image mosaic.

Fig. 1 is the structural representation of embodiments of the invention 1；
Fig. 2 is the imaging schematic diagram of embodiments of the invention 1.
Embodiment
With reference to embodiment, the invention will be further described, but does not form any limitation of the invention, any
In the modification for the limited number of time that scope of the invention as claimed is made, still in scope of the presently claimed invention.
Embodiment 1
As shown in Figure 1-2, a kind of camera device, including 3, two cylinder 1, sensor 2, light reflection element fish eye lenses 4,
Described sensor 2 is connected with image-signal processor, and the field of view angle of described fish eye lens 4 is equal to 220 °, described light
Reflecting element 3 is provided with two external reflectance faces 5 coordinated respectively with fish eye lens 4, described fish eye lens 4 and corresponding outer anti-
The angle for penetrating face 5 is 45 °, and the angle in described sensor 2 and external reflectance face 5 is 45 °；The axle of two described fish eye lenses 4
Heart deviation is less than 2；The distortion parameter of fish eye lens 4 is linear distortion；Described fish eye lens 4 is fixed on the both ends of cylinder 1, institute
The sensor 2 stated is arranged between two fish eye lenses 4, and described sensor 2 is arranged on the underface of sensor 2.
The operation principle of the present embodiment is that field of view angle is equal to 220 ° of 220 ° of wide angle pictures of collection of fish eye lenses 4 first,
Then wide angle picture is delivered on two external reflectance faces 5 of same light reflection element 3, by reflection, image, which reaches, to be used for
Two circular pictures can be shown on the sensor 2 of receiving optical signal, on sensor 2, image-signal processor is sensed
Signal on device 2, and by two circular picture mapping expansion as the image of bar shaped, image centre is that field of view angle is 0-
