The hexahedron column prism that can be formed in one, as shown in Fig. 2 (a), its effect is equivalent to three lists arranged in 120 degree of angles
One column prism, the light coming from the most each first battery of lens with transmission enters the second battery of lens, and at follow-up image device
(3) upper imaging, described hexahedron column prism can be equilateral or inequilateral form, as the hexahedron column of inequilateral form
Prism, as shown in Fig. 2 (b), the central angle that its adjacent edge is corresponding and a1+a2 be 120 degree, and long limit institute to central angle a2 with short
Limit to the difference of central angle a1 more than or equal to 20 degree.When above-mentioned optical module A11-A13 forms the panoramic imaging device of near-spherical,
Along the periphery predetermined direction of shell, the first battery of lens of A11 optical module and the adjacent cloth of image device of non-optical assembly A11
Put.
As a kind of mode of texturing, the intermediate prism in above-mentioned first embodiment can be formed as corresponding A 11-A13 optics
Three pentagon prisms of assembly, and each have total reflection surface, from the light of the first battery of lens through pentagon prism
Light entrance face enters in prism, and reflects on total reflection surface, then goes out to inject the second battery of lens via light exit surface, as
Shown in Fig. 3.Now, two adjacently situated surfaces of pentagon prism are respectively as light entrance face and light-emitting face, in the face of first and the
Two battery of lens.When forming the panoramic imaging device of near-spherical, along the periphery predetermined direction of shell, the of A11 optical module
The image device of one battery of lens and optical module A11 is adjacently positioned.
In above-mentioned first embodiment and mode of texturing thereof, the plane of incidence of each intermediate prism and exit facet can be formed as tool
There are sphere or the aspheric surface of focal power, to provide certain focal power, help the correction of part aberration, thus obtain preferably
Image quality.
According to the second embodiment of the present invention, as shown in Figure 4, including four set optical modules, wherein, optical module is respectively overlapped
The optical axis of A111-A114 can non-coplanar (using outermost lens markings as signal), four set optical modules each optical axis mutual
All in 120 degree of angles between Xiang, and each optical axis all intersects at same point, similar with above-mentioned first embodiment, respectively overlaps optical module
Can have identical optical texture, such as, include the first and second battery of lens, and the intermediate prism of centre.But, respectively overlap
Optical module can also have the optical texture differed.
As the intermediate prism in second embodiment of the invention, can be formed as one in spherical overall prism, due to this
The overall prism of sample is respectively provided with identical character in each angle, therefore, when intermediate prism can in a spheroid time, it is preferred to use
Having the A111-A114 optical module of identical optical structure, each assembly optical axis is in the space angle of about 120 degree, thus maximum
Manufacture difficulty is alleviated in degree.Now panoramic imaging device is formed as the spheroid of standard, is fixed with at spheroid center
State overall prism.
As a kind of mode of texturing in second embodiment of the invention, intermediate prism can be formed as an octahedral entirety
Prism, as it is shown in figure 5, wherein every a pair parallel plane of regular octahedron is constituted corresponding to an optical module A111 (or A112-
A114 is arbitrary) light entrance face and exit facet, from the optical module A111 the first battery of lens outgoing near thing side via positive eight
One light entrance face of face body, and from the light-emitting face outgoing parallel with this light entrance face, enter optical module A111 near image side
The second battery of lens, and then imaging on image device.
It will be appreciated by those skilled in the art that the panoramic imaging device layout type including four set optical modules is also not necessarily limited to
This, as shown in Figure 6, the top view of a kind of panoramic imaging device of the present invention, on cross section, optical module A111-A113 it
Between in fixed angle, and respectively and between optical module A114 in space another fixed angle, optical module A111-A113 has
Having identical structure and areas imaging, A114 does not have the structure identical with A111, equally makes areas imaging to cover
360 degree of area of space, such arrange the use that can effectively reduce big wide angle optical assembly, alleviate panoramic imaging device synthesis
Amount of calculation during image.
According to above-mentioned each panoramic imaging device of the present invention, owing to each optical module the most all has near the lens of thing side
There is bigger aperture to collect the light in big field range as far as possible, and image device does not the most have large scale, use
The image overlapping angle of about 6 degree can meet the requirement of image synthesis, and in order to effectively control to arrive on image device
Light range, and along the compactedness needs arranged in week, selectable, near the exiting surface of prism, it is provided with diaphragm.Enter one
Step, the panoramic imaging device of the present invention also includes image synthesizer, and the image that each optical image unit obtains all is sent to
Image synthesizer carries out synthesizing to generate panoramic picture.
It will be appreciated by those skilled in the art that, although above-described embodiment illustrates and includes the complete of 3～4 set optical modules
Scape imaging device, but the panoramic imaging device of the present invention is not limited to this composition, can include the optical module of more set, more
Optical module uses the requirement that can reduce each optical module areas imaging.
Particular embodiments described above, has been carried out the purpose of the present invention, technical scheme and beneficial effect the most in detail
Describe in detail bright, be it should be understood that the specific embodiment that the foregoing is only the present invention, be not limited to the present invention, all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, should be included in the guarantor of the present invention
Within the scope of protecting.
