Abstract
The utility model relates to a device for taking a shot subject and multi-visual angle pictures one time with one camera, which comprises a camera and a flat reflecting mirror. The camera and the shot subject are arranged on the same vertical side, and the flat reflecting mirror is arranged on the other vertical fan side opposite to the camera. The flat reflecting mirror is provided with an m groups which are arranged longitudinally, and each group is provided with n blocks which are arranged transversely. M directions corresponding to the positive front, upper front and lower front of the shot subject can be shot one time by the device, and each direction is used for shooting m * n views of the same subject at the same time from left, middle and right n angles.
Description
The utility model relates to the device that camera of a kind of usefulness is once taken the various visual angles image of subject, belongs to the photographic imagery technical field.
In order to take certain object (as the personage's, workpiece, handicraft etc.) image from a plurality of visual angles, be designated hereinafter simply as the various visual angles image, traditional image pickup method has two big classes:
1. use many cameras (camera, video camera ...) take from each visual angle simultaneously, every camera clap a width of cloth, the common various visual angles image of forming.This method equipment complexity, the cost height need have large stretch of place of taking, and is not easy to flow and takes;
2. use a camera, take from each visual angle successively, once obtain the image at a visual angle, form the various visual angles image at last, specific practice can be that object is motionless, and mobile one by one camera is taken; Also can be that camera is motionless, rotate subject one by one.
Time-consuming, the trouble of said method, and work as state (position, attitude, the expression of object ...) when changing, can't obtain the various visual angles image under the same state.
The purpose of this utility model is a kind of device of design, and the enough cameras of this device energy are once taken the various visual angles image of subject.Utilize the specific position relation between camera, subject and the level crossing, from subject just before, go forward, down before m direction, m * n width of cloth view that each direction divides n angle to take subject simultaneously with left, center, right.
Camera of usefulness of the utility model design is once taken the device of subject various visual angles image, comprises camera and plane mirror.Camera and subject place same vertical plane, and plane mirror places on another vertical covering of the fan relative with camera.Plane mirror has m row, becomes vertically to arrange, and every row has the n piece, becomes transversely arranged.If the vertical field of view angle of camera is α, then the angle between the reflecting surface of the m face mirror of vertically arranging equals
, the horizontal field of view angle of establishing camera is β, the angle between the reflecting surface of then transversely arranged n face mirror equals
Description of drawings:
Fig. 1 is a front elevation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 be utilize the utility model take the photograph 15 width of cloth views of subject.
Fig. 4 is ten five width of cloth views of subject when being the personage.
Below in conjunction with accompanying drawing, introduce an embodiment of the present utility model in detail.Among the embodiment, m=3, n=5.Among Fig. 1, the 1st, subject, the 2nd, camera, the 3rd, backcloth, O are the object lens center of camera, P is the front mid point of subject, M

The device of the utility model design is applicable to the not too big situation of angle between each visual angle, Fig. 1 is a structural representation, with it can once take be equivalent to from object just before, go forward, following first three direction, each direction respectively from the left, center, right five angles take 15 width of cloth views of same target simultaneously, shooting effect is as shown in Figure 3 and Figure 4.Among Fig. 3,3-1 to 3-15 is the virtual image of subject in catoptron.Fig. 1 is the front elevation (one group of level crossing of vertical arrangement of only having drawn) of read apparatus, and Fig. 2 is the upward view (the transversely arranged row's mirror in the middle of only having drawn) of Fig. 1.
Once clap the image at a plurality of visual angles be arranged in the same images, in order to make full use of the breadth of image, preferably make the image size at each visual angle identical (at least should be close), be full of the view picture picture altogether as far as possible.For example in Fig. 1, the vertical field of view angle of establishing camera is α, and the angle that then preferably makes upper, middle and lower three arrange between the reflecting surface of mirrors equals (or being slightly less than) α/3, the picture Is of so certain object in three row's mirrors

The place.The width of mirror should make full use of the visual field and not block mutually again.
In addition, be preferably in the reference object back and place monochromatic backcloth, in order to avoid the image that obtains is mixed and disorderly.
