Police and prosecutors sometimes recreate crime scenes in an effort to better understand complex cases.
警方和检察官有时会重建犯罪现场来更好地了解复杂的案情，

They may set up a room to make it look like the room where a murder took place.
他们可能会设置一个看起来像谋杀现场的房间。

To do this, they use photographs from the murder scene to set up tables, chairs and other objects just where they were at the time of the murder.
为做到这一点，他们使用犯罪现场的图片来安放桌椅等物品，将它们放置在谋杀发生时所处的位置。

Now, scientists in Switzerland are developing virtual reality technologies to recreate crimes scenes.
现在，瑞士科学家开发出一种能重建犯罪现场的虚拟现实技术，

The scientists say these computer-made images can be used for quality recreations of events.
科学家称这种电脑图像可以用于事件的高度还原。

They say this kind of technology can help police, investigators, judges and lawyers better visualize crime scenes.
他们说这种技术可以帮助警察、调查人员、法官和律师更好地将犯罪现场形象化，

They say it can even perform virtual autopsies – recreating examinations of human remains.
甚至可以进行虚拟的尸检，还原尸检的情况。

The scientists work at the Institute of Forensic Medicine in Zurich. They developed special computer software to create this virtual reality technology.
这些科学家就职于苏黎世法医研究所，他们开发专门的电脑软件来创建这种虚拟现实技术，

The software program is called Forensic Holodeck. It recreates crime scenes using hand-held three-dimensional, 3-D, scanners.
这种软件名叫法医全息甲板，它使用手持三维扫描仪来重建犯罪现场。

The scanners show the user an object's length, width and height. The scientists also use the Oculus Rift headset, equipment often used for video games.
这种扫描仪能显示物体的长度、宽度和高度，科学家还使用通常用于视频游戏的Oculus Rift耳机。

Investigators use the three-dimensional images to reconstruct the crime. The images are based on reports from witnesses and camera recordings.
调查人员使用这种三维图像来重现犯罪，这些图像基于目击者和摄像记录的报告。

Steffen Ross is a radiologist at the Institute of Forensic Medicine. Mr. Ross explains how the technology works.
斯特芬·罗斯是法医研究所的放射专家，他解释了这种技术是如何工作的。

"We scan the crime scene and we are also able to scan the dead body, if there is a dead body involved,
“我们会扫描犯罪现场，如果有尸体存在，也会扫描尸体，

and then we can put all the data together in the computer and create a virtual crime scene, which is a 3D model of the crime scene."
然后将所有数据输入电脑，创造虚拟的犯罪现场，也就是三维的犯罪现场。”

The software also rebuilds trajectories of bullets. Red and yellow lines are used to show their movement through the air.
这种软件还能重建子弹轨迹，红线和黄线被用来显示子弹在空中的运动。

Mr. Ross says the technology gives the scientists a better idea of the trajectories than a traditional, two-dimensional image.
罗斯说，与二维图像相比，这种技术让科学家更好地理解子弹轨迹。

In addition to the virtual reality technology, the institute also developed a robot named Virtobot.
除了虚拟现实技术外，该研究所还开发了名为Virtobot的机器人，

Medical examiners can use Virtobot to perform virtual autopsies in great detail.
法医可以使用该机器人来进行更详细的尸检。

Robert Breitbeck is a scientist with the Institute of Forensic Medicine. He says the system provides a 3-D model of the human body.
罗伯特是法医研究所的科学家，他说该系统能制作人体的三维模型。

He says scientists can make images of the injured skin in color and true to the exact size.
他说科学家可以制作出伤口的图像，使其颜色和大小与实际相同。

This information can be stored, and later combined with three-dimensional data, which police can provide.
这种信息可以储存起来，然后与警方提供的三维数据配合起来。

From this information, he says, the scientists can do 3D reconstructions, or recreate images, from murder cases or traffic accidents.
他说通过这些信息，科学家就可以进行三维的图像重建，包括犯罪现场和交通事故。

Several countries are already using both systems – the virtual reality technology and Virtobot. I'm Jonathan Evans.
几个国家已经在使用虚拟现实技术和Virtobot这两个系统。我是乔纳森·伊万斯。
