捷克科学家提出了一种不用深入洞穴就能探索洪水淹没的洞穴系统的方法。
Czech scientists have come up with a way to explore flooded cave systems without having to go into them.

他们的解决方案是:创建一个洞穴的三维(3D)地图。
Their solution: create a three-dimensional (3D) map of the cave.

一家名为Geo-CZ的公司开发了一种新的途径,使用3D技术来绘制历史和考古区域的地图。
A company called Geo-CZ developed a new tool that uses 3-D technology to map historical and archaeological areas.

本月早些时候,捷克共和国的洞穴管理局对此进行了展示。
The Cave Administration of the Czech Republic demonstrated it earlier this month.

Geo-CZ的吉里·辛德拉说:“输入的数据不是由单独的图片组成,而是视频。
Jiri Sindelar of Geo-CZ said, “The input data are not made by individual pictures, but videos.

这使得现场测绘速度快得令人难以置信。”
This makes the on-site mapping incredibly faster.”

为了制作3D图像,潜水员在进入洞穴之前仍然需要穿上潜水衣、戴上头盔和其他设备。
To produce the 3-D images, someone still needs to wear a wet suit, helmet and other equipment before going into the cave.

拍摄过程只需要进行一次,而且只需要拍摄足够长的时间。
That has to be done only once and only long enough to film it.

该技术是十分有帮助的,因为大多数洞穴都在地下,可能光线黑暗。
This is helpful because most caves are underground and can be dark.

此外,当洞穴被洪水淹没时,可能会非常危险。
In addition, caves can be seriously dangerous when they are flooded.

去年,12名泰国学生和他们的足球教练被困在一个被洪水淹没的洞穴中18天才获救。
Last year, 12 Thai schoolboys and their football coach were trapped in a flooded cave for 18 days before being rescued.

Geo-CZ公司在捷克首都布拉格以南约100公里的一个洞穴中使用了3D测绘系统。
Geo-CZ used its 3-D mapping system in a cave about 100 kilometers south of Prague, the Czech capital.

这个洞穴于1863年被发现,五年后向公众开放。
The cave was discovered in 1863 and opened to the public five years later.

在20世纪80年代,探险家们发现洞穴系统中较低的大片区域被水淹没。
In the 1980s, explorers found lower, larger parts of the cave system filled with water.

探索仍在继续。
The exploration is continuing.

辛德拉说,这一新系统将使探索行动更加容易,所获得的发现也更加准确。
Sindelar said the new system will make the exploration much easier and the findings more accurate.

潜水员通过计算机观察洞穴的整体模型时,也能更好地了解洞穴的形状。
Divers can also understand the shape of the cave better when observing it as a whole in the computer model.

洞穴专家弗朗蒂塞克·克里卡指出:“通过3D图像中,我们可以真正地理解洞穴与整体系统的联系。
Cave specialist Frantisek Krejca noted, “In the 3D imagery, we can really realize the connections…of the whole system.

我们可以从中得到更多的信息。”
We can get much more information from it.”
