Description

Based on double vision point stereo data bore hole stereo display TV and implementation method

Technical field

The present invention relates to a kind of three-dimensional LCD TV, particularly a kind of based on double vision point stereo data bore hole stereo display TV and implementation method.

Background technology

At present, though adopt the multi-view auto stereo display technique can improve the defective (perhaps be called to improve and watch comfort level) that causes the beholder to feel dizzy owing to the parallax phenomena of inversion, but this improvement has increased the complexity that comprises the whole process that image acquisition shows to terminal from system greatly, and make and almost to become impossible with the system compatible of realizing spectacle double vision point 3D demonstration that development is popularized and even traditional 2D demonstration in advance, prior art generally is to adopt the depth information that directly obtains 3D rendering from the 2D image, and then synthesize the image information of two or more viewpoints, but because the depth information that the 2D image is comprised is a kind of implicit information, so in the process of extracting, more be to utilize the existing apriority knowledge of people, and the complete utilization of this knowledge is very difficult at present, therefore, use though the 2D-3D switch technology is existing at present, effect is barely satisfactory.

Summary of the invention

The purpose of this invention is to provide a kind ofly based on double vision point stereo data bore hole stereo display TV and implementation method, the technical problem that solve is to improve the precision that depth information extracts, and improves the 3D display effect.

The present invention is by the following technical solutions: a kind of based on the three-dimensional LCD TV of double vision point stereo data bore hole, comprise television set, be provided with depth information extraction unit, many viewpoints 3D rendering generation unit and many viewpoints 3D rendering in the described television set and play up output unit, described depth information extraction unit connects the processing unit of television set, the depth information extraction unit connects many viewpoints 3D rendering generation unit, and many viewpoints 3D rendering is played up output unit and connected display unit.

A kind of based on double vision point stereo data bore hole stereo display method, may further comprise the steps: one, the depth information extraction unit extracts the double vision point 3D rendering information that is stored in the television set; Two, the depth information extraction unit carries out filtering with the depth information that extracts, and filtered image is sent to many viewpoints 3D rendering generation unit; Three, become the bore hole 3D rendering and the bore hole 3D rendering is sent to many viewpoints 3D rendering after many viewpoints 3D rendering generation unit synthesizes filtered image and play up output unit; Four, many viewpoints 3D rendering is played up and is sent to display unit after output unit is played up the bore hole 3D rendering and play.

Depth information filtering of the present invention may further comprise the steps: one, layering is sorted out, and reduces picture depth level quantity, and depth perception between reinforced layer; Two, level is level and smooth, behind the depth perception after between reinforced layer, removes the part fluctuating point in each level.

The present invention compared with prior art, employing is from the extraction of existing double vision point 3D rendering data through depth information, and synthesize the image information that many viewpoints show needed relevant viewpoint on this basis, improve the precision that depth information extracts, improve the 3D display effect, thereby fundamentally solve problems such as film source.

Embodiment

Below in conjunction with drawings and Examples the present invention is described in further detail.

As shown in Figure 1, of the present invention based on the three-dimensional LCD TV of double vision point stereo data bore hole, comprise television set, be provided with depth information extraction unit, many viewpoints 3D rendering generation unit and many viewpoints 3D rendering in the described television set and play up output unit, described depth information extraction unit connects the processing unit of television set, the depth information extraction unit connects many viewpoints 3D rendering generation unit, and many viewpoints 3D rendering is played up output unit and connected display unit.

The present invention adopts following method to realize: one, the depth information extraction unit extracts the double vision point 3D rendering information that is stored in the television set; Two, the depth information extraction unit carries out filtering with the depth information that extracts, and filtered image is sent to many viewpoints 3D rendering generation unit; Three, become the bore hole 3D rendering and the bore hole 3D rendering is sent to many viewpoints 3D rendering after many viewpoints 3D rendering generation unit synthesizes filtered image and play up output unit; Four, many viewpoints 3D rendering is played up and is sent to display unit after output unit is played up the bore hole 3D rendering and play.

Described depth information filtering may further comprise the steps: one, layering is sorted out, and reduces picture depth level quantity, and depth perception between reinforced layer; Two, level is level and smooth, behind the depth perception after between reinforced layer, removes the part fluctuating point in each level.

The present invention is in order to extract the depth information in the existing image, traditional method is to determine the parameter of the video camera of original image earlier, and the present invention is in order to play the 3D signal of double vision point on many viewpoints 3D TV, therefore, can not suppose the making situation of these film sources and environmental parameter etc.Directly do not calculate the relevant parameter of video camera, but determine relevant parameter according to the demonstration and the best viewing location information of 3D TV.Promptly according to corresponding relation, the ratio of display size on best observed range and the television screen, and number of views is determined as Fig. 2 institute not.

The depth of field data of depth information representative of the present invention, also link up with screen display, total depth of field is not higher than half of screen width, maximum goes out screen and goes into screen distance (distant view place) ratio according to the same same depth of field (absolute value) of parallax (absolute value) generation, referring to Fig. 3 apart from (close shot place) with maximum.

The effective resolution that the present invention shows owing to many viewpoints has only the 1/N of original screen effective resolution, so, need carry out preliminary treatment to initial data, its resolution of corresponding reduction is to improve arithmetic speed, requirement of real time.

The depth information extracting method that the present invention is used, be from the double vision dot image data, to extract the 3D depth information, because the depth information that the double vision dot image itself is carried is very abundant, therefore also relatively fully, it is also very good to produce the multi-view image display effect thus for the depth information that obtains.
