Embodiment
Below, by the present invention is described in detail in conjunction with the accompanying drawings and embodiments.Following examples are not to restriction of the present utility model.Under the spirit and scope not deviating from utility model design, the change that those skilled in the art can expect and advantage are all included in the utility model.
Fig. 1 is the structural representation of the panoramic imaging device according to the utility model one embodiment.Fig. 2 is the visual field schematic diagram of the panoramic imaging device according to the utility model one embodiment.Fig. 3 is the structural representation of the reflective panoramic imaging lens of two panels according to the utility model one embodiment.
With reference to figure 1-3, in the present embodiment, polygon prism hollow housing is triangular prism hollow housing 11.This housing parts 11 has three sides, and as shown in the figure, one of them side is as the stationary plane being fixed on ceiling or other place of buildings, and two other side is as the installed surface installing panoramic imaging lens.A reflective panoramic imaging lens 12 of two panels is set respectively in the mounting hole of these two installed surfaces.
Have angle theta between two installed surfaces, θ scope can be between 0 ° to 180 °.Preferably, θ angular region is being greater than 90 ° of+α and is being less than 180 °, and α represents the blind angle of panoramic imaging lens.When θ angle is greater than 90 ° of+α, the blind area of panoramic imaging lens can be limited at the Delta Region that a size only has dozens of centimetre.When θ angle is less than 90 ° of+α, then make blind area can extend to an infinite distant place.It is to utilize single camera lens substantially with great visual angle that θ angle is less than 180 °.
Triangular prism hollow housing 11 can be made up of rigidity hard material, and such support strength is large, not yielding, and possesses optical anti-vibration and move effect.
As shown in Figure 3, the reflective panoramic imaging lens of two panels 11 comprises successively along optical axis direction from thing side: coaxial mounted first catoptron 13, second catoptron 14 and relay lens group 16, the central authorities of the second catoptron 14 have circular hole 15, and the first catoptron 13 and the second catoptron 14 take optical axis as rotation axes of symmetry.Light reflection to the first catoptron 13 of the second catoptron 14 for object in visual field is sent.First catoptron 13 is for being undertaken reflecting by the light from the second catoptron 14 and passing the circular hole 15 of the second catoptron 14.Relay lens group 16 is for carrying out aberration correction by the light of the circular hole 15 through the second catoptron 14, thus imaging on focal plane.
Wherein, the first catoptron 13 is concave mirror or convex reflecting mirror.Second catoptron 14 is indent circular band minute surface.Preferably, the surface of the first catoptron and the second catoptron all has high optical efficiency reflective film.Second catoptron 14 can adopt sphere or aspheric surface, can look technique and determine.First catoptron 13 adopts Random Curved Surface Designing or spherical mirror as required accordingly, according to reflection law, is imported by light in the circular hole of the first catoptron 13.Certainly, also can select spherical mirror or aspheric mirror by the first catoptron 13, but the second catoptron 14 needs to adopt Random Curved Surface Designing or suitable spherical mirror accordingly, still needs to follow reflection law.The choosing of the design of free form surface or spherical mirror also will depend on the first catoptron 13 and the distance of the second concave reflection 14 and the size of two mirror surfaces.
The reflective panoramic imaging lens 11 of two panels also comprises the lens protection cover 18 being arranged at the first catoptron and the second mirror outer, the form fit of the mounting hole on the edge of lens protection cover 18 and triangular prism hollow housing 11 side.
The reflective panoramic imaging lens of two panels 11 also comprises and is arranged at detector 17 on described relay lens group 16 back focal plane to form electronic image.This detector 17 is such as having high-resolution ccd detector.
The image processing part 19 that the detector 18 that the reflective panoramic imaging device of two panels also comprises panoramic imaging lens 11 reflective with each two panels is connected respectively.The electronic image that each detector 18 exports is carried out combined treatment by this image processing part 19, reduces blind area, the image of luffing angle more than 180 degree to obtain.This image processing part 19 can be existing any device with image processing function.
Referring again to Fig. 2, visual field of the present utility model principle is described in detail.As everyone knows, each independent two panels reflective overall view ring belt view field imaging camera lens can realize the angle of pitch imaging close to 180 °, this means all can to monitor all things in the just right direction of camera lens.So as the utility model the scheme that proposes, the overall view ring belt imaging in (360 ° of-θ) angular range can be realized under the assistance of two camera lenses, and the blind area of reflective for single two panels overall view ring belt view field imaging camera lens is tapered to less scope, as shown in Fig. 2 shaded region.The blind area (as Suo Shi Fig. 3 (B)) that the shaded region of originally single camera lens can be formed when being single lens imaging.Compare and can find out significantly, the blind area formed when the utility model can reduce single lens imaging greatly.Further, the luffing angle of overall imaging is more than 180 ° (being 360 ° of-θ), and whole monitoring visual field can comprise the scope in I region and II region.Wherein, II region can also realize 3D imaging.
θ angular dimension between above-mentioned blind area scope (Fig. 2 shaded region) and Liang Ge side, camera lens 11 place and camera lens are to the distance dependent of adjacent side common edge.θ angle is less or camera lens is longer to the distance of this common edge, and so blind area scope is larger.In practical application, the size of blind area can be reduced to dozens of centimetre this order of magnitude, and under the condition of overall background imaging, the impact of size on imaging of this blind area scope is negligible.
Further, in the scope of common edge dead ahead, above-mentioned side θ angle, (II scope) two camera lenses can imaging simultaneously, achieves same object different angles imaging within the scope of this, i.e. 3D imaging.And according to binocular location technology, the location of object in θ angle can be realized.
