Background technology
3D show be utilize people two soon to existence slightly the image reconstruction of difference go out the sensation of the degree of depth.3D rendering has comprised the slightly image of difference of two width of cloth, one width of cloth enters left eye, one pair enters right eye, and the visual information that the processing of binocular vision passage and transmission eyes obtain synthesizes the image that a pair has spatial depth and dimensional information by brain with these two differentiated images.It is formal because the image co-registration mechanism of brain makes us " see " that object is in the influence in space.
Existing 3D imaging technique mainly contains three kinds:
1, aberration formula 3D technology, the auxiliary equipment that 3D shows only need be bought once secondary dark purple (reddish yellow indigo plant) aberration glasses and can realize.But aberration formula 3D technical difficulty is low, with low cost, but the 3D glasses are to use absorption filter, and colour filter is not thorough, so there is the ghost image problem; Color filter film monochromatic light percent of pass watches brightness low greatly about 10-30%, and color filter film is unbalanced to each wave band colour filter ratio, can cause the variation of color.
2, polarization type 3D technology also is polarization type 3D technology, belongs to passive 3D technology, and the glasses price is also comparatively cheap, present 3D movie theatre, and what 3D etc. adopted mostly is polarization type 3D technology.The polarization type glasses are cheap, and 3D effect is outstanding, and the market share is big, poach to swing when still watching projection to occur.Installation and Debugging are frequent, and the movie theatre cost of investment is big, and are too big separately in the TV applications technology, the cost height.
3, bore hole formula 3D technology, bore hole formula 3D technology is in development mostly, and is mainly used in the commercial demonstration of industry market, so mass consumption person's contact is few.
Therefore, in the prior art, the major defect of 3D imaging device is:
1. filter is unbalanced to each wave band colour filter ratio, can cause the variation of color, watches brightness lower;
2. the polarization type glasses can not swing when watching, and adaptability is not strong;
3. the bore hole optometric technology is immature, for popular.
