文本解說

探索洞穴，尤其是充滿洪水的洞穴，是一件非常危險的事情。最近，科學家研制了一種新方法，那就是研制出了洞穴的三維地圖。在以后的探索任務中，科學家們無須進入洞穴便能夠了解里面的情況。

Czech scientists have come up with a way to explore flooded cave systems without having to go into them.Their solution is to create athree-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 Republicdemonstratedit earlier this month.

Jiri Sindelar of Geo-CZ said,“The input data are not made by individual pictures,but by videos.This makes theonsitemapping 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 3Dimagery,we can really realize the connections of the whole system.We can get much more information from it.”
