随着视频技术的不断发展,3D投影显示技术越来越被人们所熟知。同电视行业由黑白到彩色的过渡一样,影像显示的未来也必然会经历由平面走向立体。从最早的彩色立体三维技术問世至今,3D投影显示技术已经有几十年的发展历史,但被人们所熟知也不过是近几年的事。其中3D电影对于3D技术的推广可谓是功不可没,尽管要戴上特殊的眼镜,但这丝毫不会影响人们对3D电影的热情。很多科技馆都有自己的动感影院,里面或多或少的都运用到了3D投影技术。本文以目前普遍应用的3D投影技术为重点,详细介绍了其在科技馆动感影院中的应用,并大胆设想未来动感影院的发展方向及经营模式。

With the development of the video technology, the 3D projection technology is increasingly well known. Like the TV industry from black-and-white to color transition, image display in the future will be experienced by the planar to stereo. From the earliest color three-dimensional technology come out so far, 3D projection display technology has been developed for several years, but be known in recent years. The 3D film for the 3D technology is undeniable. Althought we have to wear special glasses, this does not affect peoples passion on 3D film. Many science and Technology Museum has its own theater, which more or less are applied to the 3D projection technology. In this paper, with the universal application of the technology of 3D projection as the focus, the paper introduces the technology in the museum theater applications, and bold vision of the future cinema development direction and business model.

一部《阿凡达》电影引爆了国内3D热潮,3d是three-dimensional的缩写,就是三维图形。我们用肉眼或带上特殊的眼镜看到的3d图形,就是在平面里显示三维图形。近年来,各地科技馆都兴建了自己的动感影院,那些待建或已经建成的动感影院中,3D投影都是被首先考虑的一项应用技术。

一、现如今3D投影技术的分类及其原理

目前比较常见的3D技术包括,彩色立体三维,偏振三维,立体三维以及最新的DLPLink技术。这四类技术是当前被广泛采用的3D投影技术。由于各自的原理不同,成本不同,效果不同,也分别占有了不同的市场。

1.成本最低廉的彩色立体三维技术

我们可以自己试着分别用红笔和绿笔在一张白纸上写字,透过红色镜片后,白纸也变成了红色,就看不到红色笔写下的字,但是可以看到绿笔写下的字。……
