这里是美国之音科技报道


High-quality systems used in video conferencing are called telepresence systems. The images are life-size yet not truly lifelike. They lack the depth that people would normally see if they were in the same room together. But this could change in the future with new kinds of three-dimensional telepresence systems.

应用在视频会议的高端系统被称为远程呈现系统。 这些系统呈现的图像与实物大小一样但没有真正达到栩栩如生。他们缺乏当人们同处一室时通常会看到的深度。但是,有了这个3-D系统,就能够改变这个状况。


Last week, we told you about a 3-D system at the University of Arizona. Researchers can send a moving image over the Internet and show it on a special screen in close to real time. People would not have to wear special glasses like they often need to watch 3-D movies.

上周,我们讲述了亚利桑那大学的一个3 - D系统。 研究人员可以通过网络发送一个动态图像并在一个特殊屏幕上同步显示。人们不必像通常在看3D电影时一样戴特制的眼镜。


The system uses a lot of cameras to take pictures of a person from different positions. Lasers reproduce the pictures combined into three-dimensional images, or holograms. The image appears more realistic with the more cameras that are used and the more pictures that are taken.

该系统用很多相机从不同的角度给一个人拍照。并通过激光合成为3D图像,或称为全息图像。相机以及相机采集的图片越多,3D图像看上去就越真实。


Howard Lichtman is president of the Human Productivity Lab. His company advises other companies on buying and using telepresence systems. Mr. Lichtman also publishes Telepresence Options, which reports on the industry.

Howard Lichtman是人类生产力实验室的总裁。 他的公司建议其他的公司购买,使用远程监控系统。Lichtman先生也发表了对远程呈现行业的看法。


He says this latest development would have done wonders for the "Star Wars" movie with the famous "Princess Leia" hologram scene.

他说,这项最新的发展通过莱娅公主全息场景给电影《星球大战》创造奇迹。


HOWARD LICHTMAN: "For Princess Leia to talk, Princess Leia needs to move and her mouth needs to move, etc. And you haven't been able to do that with a regular hologram because the hologram would only be fixed in one spot. What they're able to do is, they're able to refresh that image so that the image changes the same way a person changes when they talk."

HOWARD LICHTMAN:“因为莱娅公主说话要动,她的嘴需要移动等,用普通的全息图无法完成这些,因为这个全息图仅仅是固定在一个点上。他们能够做的是,他们能够刷新该图像,这样就能和人说话时的动作同步。”


The researchers in Arizona say their 3-D system is still years away from completion. Even then, Howard Lichtman says it may have trouble competing with systems already on the market.

亚利桑那州的研究人员说,他们的3 - D系统还未能完成。 即便如此,Howard Lichtman说,它们可能遇到当前市场上现存系统的竞争。


Most telepresence systems are two-dimensional. But Mr. Lichtman says the images are very realistic.

市场现存的大多数网真系统是二维的。 但Lichtman先生说,图像呈现的非常真实。


HOWARD LICHTMAN: "It's a 2-D image, but it's crystal clear, photo realistic, fluid movement, accurate flesh tones, and you would swear you were in the same physical space with people who might be thousands of miles away."

HOWARD LICHTMAN:“这是一个2 - D图像,但它非产清晰,逼真,流畅,色调准确,你会以为你能和千里之外的人在同一个空间内。”


He says prices for telepresence systems are going down as more people use the technology.

他说,随着越来越多的人使用这项技术,远程呈现系统的价格正在下降。


HOWARD LICHTMAN: "It's pushing down to everybody as these environments are becoming publicly available or you can rent them by the hour, and at the same time that you're getting very high quality, high definition video conferencing showing up on mobile devices and in the home delivered through the set-top box or through the PC."

HOWARD LICHTMAN :“随着这类使用环境越来越平常,它也越贴近每个人的生活。你可以按小时租用。随后通过移动设备,或在家里通过机顶盒或电脑进行非常高品质、高清晰的视频会议。”


A new eighteen-million-dollar project aims to create eleven telepresence centers for federal employees around the United States. The government is working with the AT&T company to save money and reduce pollution by reducing the need for travel.

美国政府启动了一个为联邦雇员建立11个新的远程呈现系统的项目。该项目将耗资18亿美元。政府现正与AT&T公司合作,通过降低出行实现节约资金和减少污染的目的。

Taking a Closer Look at the Future of Video Conferencing

High-quality systems used in video conferencing are called telepresence systems. The images are life-size yet not truly lifelike.
