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 utility model：
The utility model passes through specifically fish-eye selection, the selection of specific light reflection element, and specifically
The selection of fish-eye installation accuracy can improve picture authenticity, improve picture splicing precision.
Specifically, the utility model uses the light reflection element with two external reflectance faces to overcome traditional interior anti-
The mode requirement unified to optics refractive index is penetrated, cuts or be molded by two external reflectances on one piece of light reflection element
Face, as long as machining accuracy reaches 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 utility model, this avoid edge deformation to lead
The problem of montage degree of accuracy of cause is low.
Meanwhile the utility model also limit the axle center deviation between two fish eye lenses, so when image is in sensor
On when shown, its concentricity is high, using the montage to head portrait, improves the accuracy of image mosaic.

Fig. 2 is the imaging schematic diagram of embodiment 1 of the present utility model.
Embodiment
With reference to embodiment, the utility model will be further described, but does not form to of the present utility model any
Limitation, the modification of any limited number of time made in the utility model claims scope, still in claim of the present utility model
In the range of.
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
