Description

Stereo viewing mirror and display method

Technical Field The present invention relates to an image display and viewing device, especially a stereoscopic image display and viewing device.

Background Art Viewing stereoscopic images requires the left and right eyes to see the left and right images with parallax respectively. Since the two eyes of a person look at the same target, the line of sight will not be separated from the two sides, so it is necessary to watch a pair of "stereoscopic images" with parallax that are put together in parallel. For "pair" images, the middle distance between the left and right images cannot exceed the distance between the two eyes of a person, which limits the frame area of the stereo pair image, which is acceptable for photosensitive material pictures with high resolution. The image can be enlarged to get a good effect. Although the image is enlarged, the line of sight of the two eyes will not be separated, and the effect of viewing stereoscopic images in this way is very good. But in today’s digital age, it’s not enough to use this method to watch on the display screen. The pixel density of the display screen is much lower than that of photosensitive film. If the image is reduced to the required frame size, the image pixels will be greatly lost. The lost pixels cannot Use an optical magnifying glass to restore. To make the picture have as many pixels as possible, only by increasing the display area, so the stereoscopic film viewer needs to watch the whole screen to obtain as many pixels as possible. Inquiry has a patent. The existing large-format "electronic video stereo viewer" uses a prism to change the optical path, so that the parallel lines of sight of the two eyes are separated to the two sides at the prism. Although this method achieves the effect of opening the line of sight , but the line of sight is obliquely facing the screen, so the image will be deformed, and the deformed parts of the left and right images are just opposite. There will be a big difference between the two images through the superimposition of the brain, and it will produce an uncomfortable feeling when watching. Similar problems exist in the patent of "Stereoscopic Imaging Mirror and Stereoscopic Viewing Mirror". The middle of the imaging part of the left and right views is equal to the right and left edges of the left and right views with the lens respectively, and the deformed part of the two parallax images away from the edge of the lens just corresponds to the unchanged part of the other parallax image, which still has the defects of the above-mentioned viewing effect.

Summary of the invention In order to make the stereoscopic image have a better effect, make the image more delicate, and make the operation more convenient, this invention makes full use of the advantages of digital technology, processes the image with digital technology, displays the image through the full screen of the high-definition device, and then uses it Coordinated optical equipment—stereo viewer to watch the whole screen, through such soft and hard cooperation, the reproduction of stereoscopic images is simple and easy, and the effect is perfect.

The scheme adopted by the present invention is: through software, two stereoscopic sub-pictures with left and right parallax obtained by a dual-lens stereo digital camera or a digital video camera are put together to form a stereo pair digital image file; Determine the size of the image at the highest rate, display it on the screen in a full-screen manner, and display the two sub-pictures of the stereo pair on two monitors of the same specification through the support of the dual-screen graphics card, so as to obtain the highest possible image resolution Rate. In order to cooperate with the display of digital stereoscopic images on the screen, the stereoscopic viewing mirror can adjust the width of the two lines of sight, and can watch screens of different sizes, and can also watch it facing two monitors; it can choose direct viewing and horizontal zooming, and watch compressed and Stereo images without compressing the format; there is an adjustable baffle plate to block the interference of useless images and improve the viewing quality; the two eyepieces, namely the reflector (1), the cylindrical mirror (4) and the other reflector (1), can be adjusted The function of the distance between the cylindrical mirrors (4) is to adapt to the distance between human eyes and adjust the virtual image distance on the screen.

The beneficial effect of the present invention is that, with the development of digital technology and the continuous improvement of the display equipment level, the display and viewing method of the stereoscopic image can make full use of and exert these advantages, and the display of the stereoscopic image is made easier to operate, and the image is clearer. Delicacy, which is of great significance to the popularization of stereoscopic images and the revolution of visual technology.

Detailed ways

1. Make and display stereo images

By software, two stereoscopic sub-images with left and right parallax obtained by a dual-lens stereo digital camera or a digital video camera are combined left and right to form a stereo pair image file.

For single-screen display, the three-dimensional image is determined according to the resolution of the display screen, and the image size is determined by compression or cropping to match the display screen format. When displaying, the full screen is displayed on the screen. Compression is to first compress or enlarge the stereoscopic image with the height pixels of the display screen (keep the original ratio), and then compress its width to the display width pixels (only width compression); cropping is to first divide the left and right images according to the height of the display screen Pixel compression or enlargement (keep the original ratio), and then start from the middle of the sub-picture, measure to the left and right sides, cut off the pixels beyond 1/4 screen width pixels, and then combine the two cropped sub-pictures into a three-dimensional for image files.

For dual-screen display, if the computer is equipped with a graphics card that supports dual-screen, compile a short program that calls the image-viewing software. When assembling the stereo pair files, you can only do splicing. When displaying, call the image-viewing program and then convert the image from Separated in the middle, the full screen is opened in two screens respectively.

For video files, compile a short program that calls the player. When running the program, first select the left and right parallax video files through dialogue, and then play them simultaneously in two windows that are divided equally on the left and right sides of the screen. The playback screen is set to be compressed by the window, and the original format can be restored through the horizontally enlarged viewing mirror. For devices with dual-screen displays, the calling program is set to play in full-screen on the two screens.

Stereo pair generation software has the function of batch processing stereo photo files. The software first lets you select the photo file name of a certain parallax to generate stereo pair files, and then automatically finds files with the same name in another folder and generates them all automatically (Stereo camera shot The left and right image files have the same name and are saved in different folders when downloaded), the type of generated stereo pair file depends on the display type set by the user.

2. Watch the stereoscopic image with the stereoscopic viewing mirror

The three-dimensional viewing mirror is a device that reflects the light path of the two eyes twice. The purpose is to open the line of sight seen by the two eyes and face the two half screens of the screen (Figure 1), or face them together Two screens, the screens of the two screens are vertically facing the viewing mirror. The main structure of the three-dimensional viewing mirror is shown in Figure 2, and the line of sight is reflected twice by the reflectors (1, 2) to achieve the purpose of widening the line of sight. The opened line of sight distance can be adjusted by the angle of the reflector 2, and its adjustment is realized by a set of gear and rack linkage mechanism (10, 11, 12 in Fig. 2), and the reflector (2) is fixed on a turntable (9 ), twist the gear (11) to drive the rack (12) to move, and the rack moves to drive the gear (10) to rotate, thereby driving the turntable (9) to rotate, thereby adjusting the mirror (2) fixed on the turntable angle.

Horizontal magnification is achieved by using a concave cylindrical reflector as the reflector (2). The concave cylindrical reflector and the plane reflector are fixed on the turntable (9) back to back, and the turntable is rotated half a circle to realize direct viewing and magnification. s Choice.

While twisting the adjustment gear (11), it also drives the double concave cylindrical mirror (4) to appear and disappear, and the cylindrical mirror mainly cooperates with the concave cylindrical reflector for focusing.

The reflector (1) and the cylindrical mirror (4) as the eyepiece are connected on a plate, and the distance between the eyepiece and the other way is also adjustable.

The three-dimensional viewing mirror can also be realized by a prism in addition to being realized by a reflector (Fig. 3).

The stereo viewing mirror is equipped with a movable light shield (6, 7), the purpose is to block another picture of the stereo pair, and meanwhile, the light shield also doubles as a lens cover.

When watching a stereoscopic image with a screen viewer, it is like watching a telescope through the screen viewer to watch the screen. The viewing distance is similar to that of the usual screen. It can also be fixed on the bracket to watch; for the stereo pair image that has been compressed in width, use the horizontal zoom function to watch, and the ratio of horizontal zoom can be adjusted through the viewing distance; for the horizontal zoom function, you need to adjust the eyepiece (4 ), so that the viewing screen is clear; for the stereoscopic image displayed on the double screen, put the two monitors side by side together, the screen is vertically facing the viewing mirror, use the function of direct viewing and adjust the width of the line of sight to watch; adjust the two eyepieces (mirror 1. The distance between the cylindrical mirror 4 and the other reflecting mirror 1 and the cylindrical mirror 4) can not only adapt to the distance between the two eyes, but also can adjust the distance to watch the virtual image on the screen; adjusting the shading range can shield the interference of useless images, Improve viewing quality.
