Abstract

Current 3D images or videos require specific image capturing techniques by using two lenses, and eye glasses corresponding to the employed capturing technique are used, during playback, to parse a file to generate 3D stereo images. The present invention determines, by means of optical analysis in physics, 3D elements in a 2D image or video frame, and provides, according to research and analysis related to ergonomics, a theory and method for capturing the 3D elements in a 2D image or video frame. The present invention achieves a breakthrough in existing 3D image and video technology concepts, and shifts the object capture source from image capture of real objects to already-captured 2D video or images. When a user wears glasses to capture (view) a frame, a restored 3D image or video frame is seen by the user by means of optical processing of the glasses, such as separation of 4-dimensional video element groups, and visual differences. The present invention enables all 2D image or video sources to be 3D sources, and enables, by simply wearing the glasses, ordinary films or television to be viewed as 3D films or television.

Description

Theoretical method and glasses device for converting 2D video into 3D video

Detailed description of invention patents:

1 technical field:

The 3D glasses currently used in the field of 3D video technology are all viewed for the well-prepared 3D film source. For ordinary 2D movies, 3D video cannot be seen through this type of glasses. In this technical field, people have so far It has not invented an effective 2D video to 3D video glasses and device. In theory, it is due to the research and deep understanding of the physics and optics of the "stereoscopic sense" of the human eye. Accurately caused. This technical field of direct and accurate 3D video from 2D video is still blank.

2 background technology

At present, 2D video is shot with a single camera. 3D video is taken with a dual camera. The single-lens video is taken from a single-eye view when viewed with a single eye. It is a flat 2D video with both eyes. When using two cameras When shooting the head, I got two "different" shooting videos of the same picture. By combining the two videos through post-production, when the glasses are viewed, the left and right lenses respectively parse out the synthesized two videos, and we see the restored 3D. Video.. However, since the existing 3D video shooting is restricted by the lens angle, the panoramic 3D picture cannot be taken.

3 invention content

The invention contains invention theory and glasses device.

1) Invention theory

Firstly, according to the basic theory of physics 'optics and ergonomics, the single lens captures the video to obtain the integrity of the information, that is, the "stereo" element information in the video when the single lens is taken is completely recorded. According to the ergonomic analysis, the two eyes can not be analyzed. The reason for directly seeing the stereoscopic element information of 2D video points out that when we look at 2D video directly with both eyes, we see the same three-dimensional elemental information group, which interferes with each other and destroys the three-dimensional elements in the two eyes. "Generation", we can only see the plane 2D view, that is to say. Both eyes will produce 'interference' with the same three-dimensional element group. We can't see the 3D stereoscopic video. From the above analysis, the core content of the invention theory is obtained: Decomposing 2D video stereoscopic element information into two equal 4D element groups of the same information , people can see 3D video.

2) Invention device----3D glasses

As shown in Figure 1: The basic appearance and principle diagram of 3D glasses shows that the 2D video element A is optically decomposed into the left lens A1 element and the right lens A2 element through the glasses. A1 and A2 are in the same information group A. The same amount of different optical information is decomposed. According to 1) invention theory, the glasses produce 3D video effects.

3. Specific implementation

The invention patent is implemented optically, and is the simplest and most practical way among the many embodiments based on the basic theory of the invention. According to the environment and scope of use, it can also be implemented electronically to obtain a more complete panorama. Deep 3D video. Glasses embodiment Figure 1 has shown and illustrated that the glasses are optical or electronic, and the details are detailed.
