Description

立体图像显示方法与系统 Stereoscopic image display method and system

技术领域 FIELD

本发明涉及一种立体图像生成显示技术,尤其涉及一种立体图像显示方法与系统。 The present invention relates to a stereoscopic image generation display technology, and particularly relates to a stereoscopic image display method and system.

背景技术 Background technique

人的眼睛看物体时,由于左右两眼所见角度不同,在两眼的视网膜上形成的像并不完全相同,这两个像经过大脑综合以后就能区分物体的前后、远近, 从而产生立体视觉。 The human eye to see objects, since the left and right eyes see different angles, the image formed on the retina of both eyes are not identical, both as integrated through the brain can distinguish objects before and after, the distance, to generate three-dimensional vision. 立体图像的原理是,用两个摄像镜头仿照人的眼睛的视角同时拍摄景象,得到左右两幅图像。 The principle of three-dimensional image is modeled using two camera lens viewing angle of the human eye while shooting the scene, get left and right images. 之后,让观看者的左右眼只分别看到相对应的左右的图像,观看者所看到的就是一幅立体的影像。 After that, let the viewer's left and right eyes only see the corresponding left and right images, the viewer sees is a three-dimensional image, respectively.

在各种立体图像显示系统中,目前已经达到实用化的方法之一是:将左右两幅图像同时在一个显示屏上显示,并且使显示屏上的像素点按像素行隔行交替显示左、右图像(图像经过传输、处理、显示后,被观看者左眼所看到的图像,简称为左图像;被右眼所看到的图像简称为右图像),即如果显示屏上的某一像素行显示的是左图像,则相邻的像素行显示右图像。 In various stereoscopic image display system, it has now reached one practical method: the left and right images simultaneously on a display screen, and the pixels on the pixel line interlaced display by alternately displaying left and right image (through image transmission process, after the display is seen by a viewer left eye image, referred to as the left image; the right eye image is seen simply referred to as right image), i.e., if a certain pixel on the display screen line displays the left image, the adjacent rows of pixels to display the right image. 在像素行的前面加上旋光膜,使相邻像素行的光线的偏振方向互相垂直,戴上偏振滤光眼镜,就可以看到立体的图像。 In front of the row of pixels optically coupled with the membrane, the polarization direction of the light pixels adjacent rows perpendicular to each other, wearing polarizing filter glasses, you can see a stereoscopic image. 该方法存在的问题是,由于左右两眼看到图像中有被偏光镜片过滤掉的间隔行,所以眼睛所看到的图像会有明显的暗线条,使立体图像的质量受到影响。 The present method is that, since the left and right eyes see images polarized lens has been filtered out of the line interval, the eyes see the image will be significantly darker lines, the quality of the stereoscopic image is affected. 有关该技术方案的详细内容,请参考网页: http:〃www.nhk-ts.co.jp/gijutsu/gi 11 -xpol.html 。 For more information on this solution, see the website: http: 〃www.nhk-ts.co.jp / gijutsu / gi 11 -xpol.html.

下面结合附图及具体实施例对本发明再作进一步详细的说明。 Specific embodiments of the present disclosure will be described in further detail below in conjunction with the accompanying drawings and. 图1为本发明立体图像显示系统的结构组成示意图。 FIG configuration stereoscopic image display system 1 is a schematic view of the composition of the present invention. 如图l所示,本发明的立体图像显示系统包括:左右图像制作单元100、混合图像合成单元110、混合图像显示控制单元120和混合图像偏振分解单元130。 As shown in FIG. L, according to the present invention is a stereoscopic image display system comprising: a left and right image creation unit 100, the mixed image synthesis unit 110, the mixed image display control unit 120 and the image mixing unit 130, the polarization division. 其中,左右图像制作单元100用于制作待成立体图像的二维左图像和右图像。 Wherein the left and right image creation unit 100 for two-dimensional left and right images stereoscopic image to be produced. 作为实施实例之一, 左右图像制作单元100为有左右两个摄像镜头的立体摄像机。 As one example embodiment, the left and right of the image forming unit 100 has two left and right stereo camera imaging lens. 立体摄像机所拍摄的左图像和右图像为数字图像,图像大小及分辨率均相同。 Stereo camera captured left and right images into a digital image, image size and resolution are the same. 左右图像制作单元100也可以是三维虛拟系统,该三维虛拟系统可根据虛拟场景自动生成左图像和右图像。 Left and right image creation unit 100 may be a virtual three-dimensional system, the system can automatically generate a virtual three-dimensional left and right images according to the virtual scene. 图2为本发明立体图像合成、显示过程的示意图,如图2所示, 标号为3、 4的方框中的视图分别为拍摄出的左图像和右图像。 Synthesis of the stereoscopic image 2 of the present invention, a schematic view of a display process shown in FIG. 2, labeled block 3, 4 are views illustrating a captured left and right images. 由于左、右图像的拍摄技术以及利用三维虛拟系统生成左右图像的技术均属于本领域技术人员的公知技术,这里不再赘述。 Since recording techniques the left and right image generation system and a three-dimensional virtual image of the left and right in the art belong to well known techniques to those skilled in the art, will not be repeated here. 混合图像合成单元110用于将左、右图像合并成用于在混合图像显示控制单元120上显示的混合图像。 The image synthesis unit 110 for mixing the left and right images into a mixed image display control unit 120 displays the combined image. 混合图像显示单元120 用于将混合图像合成单元110生成的混合图像在一个显示屏中显示,并使显示屏显示区域内每个像素点所发出的光的偏振方向与同一像素行以及同一像素列的相邻像素点所发出的光的偏振方向互相垂直。 The image display unit 120 for mixing the mixed image synthesis unit 110 generates the combined image displayed on a display screen, and the display shows the polarization direction of light emitted from each pixel region within the same pixel row and the same pixel column polarization direction of light emitted perpendicular to each other adjacent pixels. 本发明中,混合图像显示控制单元120具体为液晶显示屏、等离子显示屏或阴极射线管显示器等。 In the present invention, the mixed image to the display control unit 120 specifically LCD, plasma display or a cathode ray tube display. 混合图像偏振分解单元130用于观看混合图像显示单元120显示的混合图像。 The image mixing unit 130 for polarization division mixing the mixed image viewing the image displayed on the display unit 120. 混合图像偏振分解单元130包括左右两片偏光镜片的偏振滤光眼镜,两镜片的偏振方向互相垂直,并且左镜片的偏振方向与显示屏上左图像像素点的偏振方向一致, 右镜片的偏振方向与显示屏上右图像像素点的偏振方向一致,这样,左镜片仅可透过左图像像素点所发的光,而右镜片仅可透过右图像像素点所发的光。 The image mixing unit 130 includes left and right polarization division two polarizing filter glasses polarized lens, two lenses in the direction of polarization perpendicular to each other, and the polarization direction of the left lens coincides with the polarization direction of the left image pixel on the display screen, a polarization direction of the right lens coincides with the polarization direction of the right image pixel on the display screen, so that the left lens is permeable only left image pixels emitted light point, only the right lens and the right image pixels permeable light issued. 使用偏振滤光眼镜看显示屏上的混合图像,就可以看到立体的影像。 Using polarizing filter glasses to see the combined image on the display screen, you can see a stereoscopic image. 以下分别详细介绍混合图像合成单元IIO和混合图像显示控制单元120。 The following are detailed image synthesis unit IIO and mixing the mixed image display control unit 120.

混合图像合成单元IIO用于将二维左图像和右图像进行变换合并处理,生成用于在混合图像显示控制单元120上显示的混合图像。 IIO image synthesizing unit for mixing the two-dimensional left and right images is converted merging process generates a mixed image on the display control unit 120 displays the combined image. 一种比较容易说明的方法是,混合图像的图像大小及分辨率与二维左图像和右图像相同,混合图像中的左图像像素组的像素点与二维左图像上对应位置的像素点相同,混合图像中的右图像像素组的像素点与二维右图像上对应位置的像素点相同。 A method is relatively easy Note that, the same image size and resolution of the two-dimensional left and right images are mixed image, pixels corresponding to the same pixel position on the left image pixel group in the two-dimensional image of the mixed left image , corresponding to the same pixel position on the right image pixels of the mixed image pixel group in the right two-dimensional image. 但是,二维左图像中与混合图像中的右图像像素组的位置相对应的像素点,以及二维右图像中与混合图像中的左图像像素组的位置相对应的像素点的信息,在变换合成处理成混合图像的过程中会损失掉。 However, the two-dimensional position of the left image and the right image in the mixed image pixel group corresponding to pixels, and information of the two-dimensional position of the right image and left image of the mixed image pixel group of pixels corresponding to points in the converting a mixed composition processing procedure of the image will be lost. 由于在混合图像中,左、右图像像素组的像素点是交替相间均勾分布的,在高分辨率的情况下,这种像素信息的损失不会对图像质量有很大的影响。 Since the mixed image, the left and right image pixels alternate pixel group are spaced hook profile, in case of a high resolution, this loss of pixel information will not have much effect on the image quality. 如图2所示,左图像3和右图像4经过变换合成处理后得到混合图像5。 As shown in FIG. 2, the left image and the right image 3 4 shifted synthesis process to obtain the mixed image after 5.

为了降低像素信息的损失对图像质量的影响,作为另一个混合图像合成实施例,在前述的实施例的基础上,将二维左图像中与混合图像中的右图像像素组的位置相对应的像素点的信息(颜色、亮度),加权叠加到混合图像中相应位置的相邻左图像像素组的像素点上。 To reduce the effect of loss of pixel information on the image quality, image synthesis mixture As another embodiment, in the aforementioned embodiment based on the embodiment, the two-dimensional position of the left image and the right image in the mixed image pixel group corresponding the pixel information (color, brightness), superimposed on the weighted pixels adjacent left image pixels of the mixed image group corresponding positions. 同样地,将二维右图像中与混合图像中的左图像像素组的位置相对应的像素点的信息,加权叠加到混合图像中相应位置的相邻左图像像素组的像素点上。 Similarly, the information of the two-dimensional position of the right image and left image of the mixed image pixel group of pixels corresponding to the weighted pixels superimposed on a left adjacent image pixels of the mixed image group corresponding positions. 这样可以有效地防止出现图像失真的现象。 This can effectively prevent image distortion phenomenon. 例如,对于左图像中的像素点,将与图3中的像素点l对应的像素点的各颜色通道的灰度,乘以加权系数O. 5,将与图3中的像素点2对应的像素点的各颜色通道的灰度,乘以加权系数0.125,然后将一个与图3中的像素点1对应的像素点的与相邻四个与图3中的像素点2对应的像素点进行加权叠加,得到混合图像中对应像素1的一个像素点的信息。 For example, for the pixel point in the left image, the gradation of each color channel of the pixel corresponding to the pixel in FIG. 3 L, by weighting coefficients O. 5, corresponding to the pixel 2 in FIG. 3 gradation of each color channel of the pixel, multiplied by a weighting coefficient 0.125, with the pixels in four adjacent pixels of the pixel corresponding to FIG. 32 and one point in the pixel corresponding to FIG. 31 weighted overlap, information of one pixel to obtain a pixel image corresponding mixed. 这样就可以降低在变换合并处理时由于图像信息丢失所产生的对图像质量的影响。 This can reduce the impact on the image quality when the image conversion information is lost due to the integration process generated.

图3为本发明混合图像的像素分布示意图。 FIG 3 of the present invention mixed pixel distribution of the image.
