Czech scientists have come up with a way to explore flooded cave systems without having to go into them. Their solution: create a three-dimensional map of the cave.(1)
捷克科学家提出一种方法,无需潜入就能探索洪水淹没的洞穴系统。他们的方案是:创建洞穴的三维(3D)地图。

A company called Geo-CZ developed a new tool that uses 3-D technology to map historical and archaeological areas.(2)
一家名为Geo-CZ的公司开发了一种新途径,使用3D技术绘制历史和考古区域的地图。

The Cave Administration of the Czech Republic demonstrated it earlier this month.(3)
本月早些时候,捷克共和国的洞穴管理局展示了这一点。

Jiri Sindelar of Geo-CZ said, "The input data are not made by individual pictures, but videos.(4)
This makes the on-site mapping incredibly faster." Geo-CZ的Jiri Sindelar称:“输入数据不是由单独的图片,而是视频。这使得现场测绘速度快得令人难以置信。”

To produce the 3-D images, someone still needs to wear a wet suit, helmet and other equipment before going into the cave.(5)
为了制作3D图像,潜水员在进入洞穴前仍然需要穿潜水衣、佩戴头盔和其他设备。

That has to be done only once and only long enough to film it.(6)
拍摄过程只需要进行一次,而且只需要拍摄足够长的时间。

This is helpful because most caves are underground and can be dark. In addition, caves can be seriously dangerous when they are flooded.(7)
该技术是有帮助的,因为大多数洞穴位于地下,并且光线黑暗。此外,当洞穴被洪水淹没时可能会非常危险。

Last year, 12 Thai schoolboys and their football coach were trapped in a flooded cave for 18 days before being rescued.(8)
去年,泰国12名学生和其足球教练被困在被洪水淹没的洞穴中18天才获救。

Geo-CZ used its 3-D mapping system in a cave about 100 kilometers south of Prague, the Czech capital.(9)
Geo-CZ公司在捷克首都布拉格以南约100公里的一处洞穴中使用了3D测绘系统。

The cave was discovered in 1863 and opened to the public five years later.(10)
1863年,该洞穴被发现,五年后向公众开放。

In the 1980s, explorers found lower, larger parts of the cave system filled with water. The exploration is continuing.(11)
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。探索行动仍在继续。

Sindelar said the new system will make the exploration much easier and the findings more accurate.(12)
Sindelar表示,这一新系统将使探索行动更加容易,结果也更加精确。

Divers can also understand the shape of the cave better when observing it as a whole in the computer model.(13)
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。

Cave specialist Frantisek Krejca noted, "In the 3D imagery, we can really realize the connections...of the whole system. We can get much more information from it."(14)
洞穴专家Frantisek Krejca指出,“利用3D图像,我们可以真正地理解洞穴与整体系统的联系。我们可以从中获得更多信息。”
