The lens outer cylinder is a N plus 1 light path structure formed by connecting and combining a reflected light path cylinder and a plurality of incident light path cylinders; the incident light path cylinders are uniformly distributed on the periphery of the reflected light path cylinder; an included angle Theta is formed by crossing the axial line of each incident light path cylinder and the axial line of the reflected light path cylinder; one lens is mounted in the light ray incidence port of each incident light path cylinder; one plane reflecting mirror is respectively arranged inside the common combining part of a plurality of reflected light path cylinders and the incident light path cylinders and on one side adjacent to each incident light path cylinder; the reflecting surface of each plane reflecting mirror is respectively directed towards the light ray incidence port of each incident light path cylinder adjacent to the plane reflecting mirrors; and an included angle Beta formed by each plane reflecting mirror and a horizontal plane is equal to Theta /2. The invention provides the panoramic pick-up head of 360 degrees which has the advantages of simple structure and low cost.

Description

360 degree panoramic shooting heads

(1), technical field: the present invention relates to a kind of camera, particularly a kind of 360 degree panoramic shooting heads.

(2), background technology: at present; in the security protection of public environment such as square, market, intersection; often need carry out conduct monitoring at all levels to entire environment; common way is that the video camera of many different shooting angles is installed at the scene; the fire ball video camera of 360 degree high speed rotating perhaps is installed; use regular meeting to break down and the mechanical rotation of fire ball video camera part is long-term, therefore, these methods all exist cost height, problem that fault is high.There is producer to adopt single bugeye lens video camera to carry out pan-shot abroad, its method is to make the light beam of a certain scope in camera lens dead ahead in not imaging of imaging surface, promptly form the circumference panoramic picture of the annular of the black Dapple of band at the center section of shooting target surface, it is to utilize coaxial double mirror can have the principle of blocking light action to realize forming annular circumference panoramic image to the scenery in its dead ahead, but the structural volume of this method is big, difficulty is adorned in the catoptron school, cost is higher; Application number is to disclose a kind of 360 degree panoramic television pick-up lenss in 200610135375.4 the Chinese patent literature, it adopts secondary light path is set in main optical path, the panorama sketch that becomes by main optical path becomes with secondary light path " black Dapple " as being incident upon simultaneously on the picture pick-up device imaging surface, form the annular peripheral panoramic image, its main optical path and secondary light path have adopted size totally 10 lens, not only cost height, and its reliability is susceptible to also.

(3), summary of the invention:

The technical problem to be solved in the present invention is: at the prior art deficiency, provide a kind of simple in structure, cost is low 360 degree panoramic shooting heads.

Technical scheme of the present invention:

A kind of 360 degree panoramic shooting heads, contain lens, plane mirror and camera lens urceolus, lens and plane mirror are installed in the camera lens urceolus, the camera lens urceolus is that a reflected light path tube is connected the N+1 light-path structure that combines with N input path tube, N is the natural number more than or equal to 2, reflected light path tube and input path tube are interconnected, N input path tube be distributed in the reflected light path tube around and the axis of each input path tube become angle theta with the axes intersect of reflected light path tube, in the light entrance port of each input path tube lens are installed all, be respectively equipped with a plane mirror in the inside of the common bound fraction of N reflected light path tube and input path tube and near each input path tube side, the reflecting surface of each plane mirror is respectively towards the light entrance port of the close input path tube of this plane mirror, each plane mirror and surface level all have angle β, and the pass of angle β and angle theta is: β=θ/2.

N input path tube be evenly distributed on the reflected light path tube around.

Reflected light path tube inside is divided into N reflection space by axial baffle, each reflection space respectively with an input path tube internal communication, each plane mirror lays respectively in each reflection space; Axial baffle is set prevents the light phase mutual interference of coming in, so that influence the quality of reflected image from different input path tubes.

Plane mirror is N the side that N orthopyramid body or N cut the orthopyramid body, and the surface that N orthopyramid body or N cut N side of orthopyramid body scribbles the reflection horizon.

N orthopyramid body or N cut the orthopyramid body and are installed in the inside of the common bound fraction of reflected light path tube and input path tube by bearing, and angle theta is 70 °～110 °; N is 2, or is 3, or is 4, or is 5, or is 6.

Reflected light path tube and input path tube are cylinder, and lens are convex lens.

The material of reflected light path tube, input path tube, bearing and axial baffle is engineering plastics or metal; The material that N orthopyramid body or N cut the orthopyramid body is a glass, or is organic glass, or is plastics.

During practical application, the light of coming in from each input path tube all enters the reflected light path tube after the plane reflection mirror reflection, be incident upon then on the video camera target surface, zones different on the video camera target surface form image, and these images promptly become plane circumference panoramic picture through after the corresponding software processes.

Beneficial effect of the present invention:

1. the present invention reflexes to the image that camera lens became of different directions on the same video camera target surface through plane mirror, solved requirement simply and effectively with single camera monitoring 360 degree panoramas, the expensive problem and the high malfunction rate of utilizing the fire ball video camera to be brought and the drawback that can not monitor in real time of utilizing multiple cameras to bring have been overcome, after adopting this 360 degree panoramic shooting head, the image that video camera receives can become plane circumference panoramic picture with corresponding software processes.

2. the present invention adopts N side that N orthopyramid body or N cut the orthopyramid body as reflecting surface, and the surface of N side scribbles the reflection horizon, and it is simple in structure, cost is low.

3. the present invention is the improvement of carrying out on the basis of existing matured product, and the material of the lens in the camera lens and the parameter of lens barrel and each parts is similar to existing product, and therefore, it makes comparatively simple.
