Abstract

In present 3D film and television, first double 2D cameras are specially used for photographing from angles to produce a 3D video, and glasses corresponding to the photographing technology are used for decomposing the two videos into 3D stereoscopic images during playback. The technical features of the method provided by the present invention are that: by means of physical and optical analysis, it is determined that there are 3D stereoscopic information elements in a 2D video, and it is found that the reason why no stereoscopic effect is produced when a person watches a 2D video using both eyes is that the "interference" effect between the two eyes makes generation of a stereoscopic effect fail; with this regard, a theory of decomposing and converting a 2D video into a 3D video and a production method are invented and a glasses device is produced by the production method. According to the present invention, the present 3D film and television technology is scientifically and theoretically interpreted, and the existing 3D technology concept is elevated to the level of a 3D technology theory, making the theoretical invention effect more scientific; thus, the photographing of a 3D film is moved from the photographing scene to a 2D video image played; when we wear 3D glasses to watch a 2D image, the glasses "photograph" a 2D video, and by means of the optical vision difference in the glasses and the 2D video 4D space-time decomposition function of electronic optics, we see a restored 3D video image. The present invention covers an invention theory production method, and is an invention of a 3D glasses production method.

分解2D视频4维空间的3D眼镜3D glasses that decompose 4D space of 2D video
发明专利的详细说明：Detailed description of the invention patent:
1.技术领域1. Technical Field
当前的3D电影拍摄技术仍旧是2D拍摄技术的拍摄方法的变换模式，2D电影和3D电影仍旧属于同一个技术领域，因为，尽管3D视频拍摄方式不同于2D视频，但3D拍摄的单拍摄机的拍摄效果完全等同于2D视频拍摄效果，所以，2D视频拍摄和3D视频拍摄的技术本质是相同的，是同一个技术领域里的两个分枝：【00021】2D视频是单镜头拍摄，是一个拍摄空间；3D视频是双镜头拍摄，是两个成拍摄角度的拍摄空间；【00022】.3D拍摄两个空间是角度空间，制作了同一个成不同角度画面的两个空间成像元素群画面视频，播放显示时，现在的3D眼镜能左右眼观看两个不同拍摄视频，产生视觉差的立体视觉感。所以，在这一技术领域中之所以至今还没有发明一种有效的2D视频转换为3D视频的3D眼镜，理论上讲是由于对人双眼对拍摄画面物理学、空间几何学、光学和人体工学的研究分析和深刻认识不准确造成的，在从2D视频画面直接获准确得3D视频的3D眼镜技术领域里仍是空白。The current 3D movie shooting technology is still the transformation mode of the 2D shooting technology shooting method. 2D movies and 3D movies still belong to the same technical field, because although the 3D video shooting method is different from the 2D video, the 3D shooting of the single camera The shooting effect is completely equivalent to the 2D video shooting effect. Therefore, the technical essence of 2D video shooting and 3D video shooting is the same, and they are two branches in the same technical field: [00021] 2D video is single-lens shooting, which is one Shooting space; 3D video is dual-lens shooting, which is two shooting spaces with shooting angles; [00022]. 3D shooting two spaces are angle spaces, and two spatial imaging element group pictures of the same image at different angles are made. , When playing and displaying, the current 3D glasses can watch two different shooting videos with the left and right eyes, resulting in poor stereo vision. Therefore, the reason why in this technical field has not yet invented an effective 2D video into 3D video 3D glasses, in theory, is due to the physics, spatial geometry, optics and ergonomics of the human eyes. Due to the inaccuracy of research analysis and in-depth understanding, there is still a blank in the field of 3D glasses technology that directly obtains accurate 3D video from 2D video images.

The invention of the glasses is to confirm that there is a 3D stereo information element group in 2D video, and the 4D spatial information imaging element group in 2D video already exists. The angle dimension and time dimension of the 2D video are decomposed in two steps to realize the current dual lens The same technical effect of shooting a 3D movie from an angle makes the existing 2D movie and video directly see the 3D movie through the 3D glasses.

空间几何数学方法分解4维空间的3D眼镜制作原理和制作方法：The principle and method of the production of 3D glasses that decompose the 4-dimensional space by the mathematical method of spatial geometry:
我们知道2D视频是一个单眼能看到的客观存在的3维成像空间立体成像元素群构成的立体视频，分析其3维空间，如图1所示X、Y、Z轴垂直相交原点O，组成空间直角座标系，图1示座标系中A空间是2D视频的3维成像空间，是X、Y、Z轴三个正维度方向上的拍摄空间大小的3维空间，这个3维空A的三个维度是X、Y、Z轴的尺寸维度。We know that 2D video is a three-dimensional video composed of a group of objectively existing three-dimensional imaging space that can be seen by a single eye. The three-dimensional space is analyzed. As shown in Figure 1, the X, Y, and Z axes perpendicularly intersect the origin O, which is composed of The space rectangular coordinate system. Figure 1 shows that the A space in the coordinate system is the 3D imaging space of the 2D video. It is the 3D space with the size of the shooting space in the three positive dimensional directions of the X, Y, and Z axes. This 3D space The three dimensions of A are the dimensions of the X, Y, and Z axes.
图1所示及图2所示，眼镜第一级，用光学分解器的光学的方法实现 理论上的数学分解4维空间，实现升级3维空间：3为空间A{x、y、z}可视为4维空间{x、y、z、0}A。依据背景技术【0003】和【00042】，把4维空间A在Z轴的旋转维度给个定维度度值-￥/2、￥/2，比如现在拍摄3D电影的拍摄角度￥，分解成附图1的A1、A2，角度维￥是分解2D视频的作为4维空间的一个技术特征。眼镜实现分解是光学方法，是用附图2所示的两个棱镜组合，通过棱镜光的“拍摄”角度不同，克服了2D视频同方向视频光对眼睛“干扰”作用，就把A空间分解为同Z轴不同维度的两个3维空间组成的4维空间的两个角度2D视频A(1)、A(2)，分解2D视频空间为同一画面的成角度的时空不同的4维空间的两个成￥角度的视频。As shown in Figure 1 and Figure 2, the first stage of the glasses uses the optical method of the optical resolver to realize the theoretical mathematical decomposition of the 4-dimensional space, to achieve the upgrade of the 3-dimensional space: 3 is the space A{x, y, z} It can be regarded as a 4-dimensional space {x, y, z, 0}A. According to the background technology [0003] and [00042], the rotation dimension of the 4-dimensional space A on the Z axis is given a fixed dimensionality value-￥/2, ￥/2. For example, the shooting angle of a 3D movie is now ￥, which is broken down into additional A1, A2, angle dimension ¥ in Fig. 1 is a technical feature of decomposing 2D video as a 4-dimensional space. The decomposition of glasses is achieved by an optical method, which uses a combination of two prisms as shown in Figure 2. The "shooting" angles of the prism light are different, which overcomes the "interference" effect of the 2D video light in the same direction on the eyes, and the A space is decomposed Two angled 2D videos A(1) and A(2) in a 4D space composed of two 3D spaces with different dimensions on the same Z axis, decompose the 2D video space into the same image with different angled space-time 4D spaces The two videos in ¥ angle.
接着，如图2所示，在眼镜装置第二级的图像分解器里，用电子光学的方法实现同一画面的两个等量的不同的画面分解。分解是以4维空间的第4维参数的时间维作为分解2D视频的另一个技术特征，用电子光学方法把A空间分解为等量的不同的时空维度空间A1、A2。我们知道进入人眼空间的动态和静态2D视频具有时间延续性，由此产生了2D视频的立体信息成像3维空间的并存的第4维，时间维，在第二级图像分解器里，分解第一级光学分解器分解出来的A(1)、A(2)空间的时间维，分解成两个成角度的同一画面的等时间量的两两不同的3维时空的2视频A1、A2......，交替进入左右眼，在人体工学的作用下，进入左右眼片幅速率控制在1/8秒～1/24秒，就能看到了3D立体图像视频。Next, as shown in Fig. 2, in the second-stage image resolver of the glasses device, two different image resolutions of the same amount of the same screen are realized by an electro-optical method. Decomposition takes the time dimension of the 4th dimensional parameter of the 4-dimensional space as another technical feature of decomposing 2D video, and decomposes the A space into equal amounts of different space-time dimensional spaces A1, A2 by means of electron optics. We know that the dynamic and static 2D video that enters the human eye space has time continuity, which results in the coexistence of the 2D video’s stereo information imaging and the coexistence of the 4th dimension, the time dimension, in the second-level image decomposer. The time dimension of the A(1) and A(2) space decomposed by the first-stage optical resolver is decomposed into two different 3 dimensional space-time 2 videos A1, A2 of the same time and the same amount of time at an angle ..., alternately enter the left and right eyes, and under the effect of ergonomics, the frame rate of entering the left and right eyes is controlled at 1/8 second to 1/24 second, and you can see the 3D stereo image video.

The composition of the electronic optics of the first-level image space-time decomposition, respectively completes the decomposition of the angle dimension and time dimension of the 2D video picture, and decomposes into two equal and different two angled 4-dimensional spaces A1 and A2 of the same picture. 2D video for left and right eyes.
