Embodiment

Now contrast description of drawings the specific embodiment of the present invention, understand for method of the present invention being had accurately, contrast Fig. 1 to 4 at first illustrates the optical principle that the present invention is based on.

In Fig. 1, image 1 be one be set at columniform cup with handles in, on plane 2, demonstrate

front view.Image

3 and 6 is respectively the image of this cup that people's right and left eyes is experienced or camera photographs, and implements the image on plane 4 and 5.Cup

image

3 and 6 subtense angles that form between right and left eyes or left and right sides camera are the β angle.

Wherein, image 3 can clearly demonstrate the bundle position of this cup, and there is difference at the bundle position that it shows than bundle position shown on image 1 front view, and is significantly more.

Image 6 can not show the bundle position on the cup; For image 6, corresponding right eye or right camera, the bundle position of this cup has just in time been blocked by the cylinder of cup itself.

Image

3 and 6 is all had any different with image 1, and is independent different mutually.Just because of this, people's visual system, according to

image

3 and 6, the people directly can obtain to be different from the space multistory image of this cup planar elevation view 1.

If directly or through after the technical finesse, combination in one plane or on the screen, what people's right and left eyes was seen simultaneously is nondistinctive, overlapping fuzzy plane picture, rather than the image of

space multistory image

3 and 6.

If the overlay plane image that

image

3 and 6 is combined into is decomposed into

original image

3 and 6 again again, also needs to carry out once more reduction technique and handle.As pointing out in front: have polarised light or light to delete method, field method is in succession arranged, colour filter method and vertical stripes method etc.Constitute the basic ideas of these methods just, make present stereo TV technique be limited to predicament.

Fig. 2 is the schematic diagram of 3 one-tenth virtual images of image 8.

In Fig. 2, image 3 is by optical lens, and 7 form the virtual image 8 in the space.This virtual image 8 is actually non-existent in space 7, only be the impression of people's vision; But for people's eyes, still the same with image 3 is the plane.

Fig. 3 is the schematic diagram of 6 one-tenth virtual images of image 9.

In Fig. 3, image 6 is by optical lens, and 7 form the virtual image 9 in the space.This virtual image 9 in fact also is non-existent in space 7, only is the impression of people's vision; But for people's eyes, still the same with image 6 is the plane.

Fig. 4 is the principle schematic of the virtual image 8 and 97 synthetic stereo images 10 in the space of Fig. 2 and Fig. 3.

In Fig. 2 and Fig. 3, the virtual image 8 and 9 that forms on the space 7 is separate, and the difference of subtense angle β is arranged.So, people's right and left eyes is different to 10 impressions of the virtual image on the synthetic space 7: this synthetic good virtual image 10 is concerning people's right and left eyes on the one hand, be different, not overlapping, on the other hand, if the synthetic good virtual image 10 is formed on the position, space 7 of same size, they give the impression of people's visual system, are exactly the stereo-picture 10 of three dimensions 7.

The virtual image 10 composition principles of Fig. 4, with respect to present existing stereoscopic imaging technology, omitted such process:

Image

3 and 6 through after the technical finesse, is overlapped on the screen or on the plane; Then, this overlapping image, reduction decomposition becomes

image

3 and 6 again, forms the process of stereo-picture with this.

Fig. 5 be the present invention with the vision signal that the video camera twin-lens obtains, change the schematic diagram of stereo-picture into.A kind of method by synthesizing space stereo image from two plane images comprises:

A. utilize the dual camera photographed, produce left and right sides vision signal;

sides vision signal

11 and 12 that technical modellings such as digitlization form can produce stereo-picture 10 equally.

Left and right sides vision signal door 11 among Fig. 5 and 12 on the one hand, do not need through existing polarised light, light delete, colour filter, field in succession or technical method such as vertical stripes method handle, directly can display

image

3 and 6, form stereo-picture; On the other hand, handle,, and keep feature the subtense angle that same object or scenery had as long as they remain two independently if they have passed through above-mentioned technical method, also can display

image

3 and 6, and can form stereo-picture equally.

Left and right sides vision signal door 11 among Fig. 5 and 12 is not as long as they are same signals, and the synchronous subtense angle to same object and scenery is arranged each other, and can be on screen each self-forming image, so, left and right

sides vision signal

11 and 12 transmission, be to finish with electronic technology or with light guide techniques, effect all is identical.

Fig. 6 represents the vision signal obtained with bicamera, merges and decomposes through the arrangement of pulse trigger, is transformed into stereo-picture.The difference of itself and Fig. 5 is, camera signals 14 and 15, before input recording/displaying device 13, signal merges through the arrangement of pulse trigger 37 and 38, trigger 37 and 38 pulse signals are by time-pulse generator 39 controls, in working order down, their signal sends and closes, and is opposite each other.

Another difference is, recording/displaying device 13 is before display 20 input signals, and signal, reverts to and camera signals 14 and 15 corresponding two paths of signals under the control of time-pulse generator 36 through trigger 35 and 34.In other words, trigger 35 and 34, will be through pulse generator 37 and 38 mixed signals, go-on-go is reduced into and camera signals 14 and 15 corresponding two independent signals, this two paths of signals respectively can be on left and

right sides screen

4 and 5, show

cup image

3 and 6, and then be formed on the cup stereo-picture 10 on the space 7.

Below in order to narrate conveniently, the importation of 13 front ends of the recording/displaying device among Fig. 6 connection, be trigger 37,38 and time-pulse generator 39, and the output of recording/displaying device 13 rear ends connection, be trigger 35,34 and time-pulse generator 36, the part of all regarding recording/displaying device 13 as, with recording/displaying device 13 be one.

Fig. 7 explanation is with the method for this method invention, and the spectacle double screen display of formation can have the plane and dual-use function solid.

It is to be noted that not every spectacle dual image television set can present stereo-picture.Has only dual image when glasses type television, when not being the same image of one-shot, and, this must be from same object to image, or on the same scene scenery, under the condition of the subtense angle β of the eyes that similar people is arranged,

image

3 and 6 formation and reproduced in synchronization just can present stereo-picture.

Adopt the method for synthesizing space stereo image from two plane images, not only the spectacle double screen display of Xing Chenging can present stereo-picture; And this spectacle dual image television set can have three-dimensional and the two kinds of functions plane.

In Fig. 7, when change over switch 16 was in A condition, the work system of Fig. 7 was the same with Fig. 5, the stereo-picture 10 that this moment, left and right

sides vision signal

11 and 12 can present among Fig. 4 and Fig. 5, when change over switch 16 was in the B state, left and right
