文本解说

探索洞穴，尤其是充满洪水的洞穴，是一件非常危险的事情。最近，科学家研制了一种新方法，那就是研制出了洞穴的三维地图。在以后的探索任务中，科学家们无须进入洞穴便能够了解里面的情况。

Czech scientists have come up with a way to explore flooded cave systems without having to go into them. Their solution is to create a three-dimensional （3D） map of the cave.

A company called Geo-CZ developed a new tool that uses 3D technology to map historical and archaeological areas. The Cave Administration of the Czech Republic demonstrated it earlier this month.

Jiri Sindelar of Geo-CZ said， “The input data are not made by individual pictures， but by videos. This makes the on-site mapping incredibly faster.”

To produce the 3D images， someone still needs to wear a wet suit， a helmet and other equipment before going into the cave. That has to be done only once and only long enough to film it. This is helpful because most caves are underground and can be dark. In addition， caves can be seriously dangerous when they are flooded.

Last year， 12 Thai schoolboys and their football coach were trapped in a flooded cave for 18 days before being rescued.

Geo-CZ used its 3D mapping system in a cave about 100 kilometers south of Prague， the Czech capital. The cave was discovered in 1863 and opened to the public five years later. In the 1980s， explorers found lower， larger parts of the cave system filled with water. The exploration is continuing.

Sindelar said the new system will make the exploration much easier and the findings more accurate.

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

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.”
