How fast does Pete's laser backpack take measurements?

文字稿

Resting place to hundreds of historical figures, Highgate Cemetery is known all over the world - but not everyone here is famous.

這里是數百位歷史人物的安息地，海格特公墓世界聞名，但并不是埋葬在這里的人都是名人。

Amongst this growing sea of ivy are thousands of headstones - some that haven't been seen in years. For many, this is what makes Highgate beautiful. But finding relatives' graves here can be tricky.

在這片長得越來越茂密的常春藤當中，有成千上萬的墓碑，有些墓碑多年都未露出。對許多人來說，這就是海格特公墓的美麗之處。但是在這里找親人的墳墓可不容易。

Well, today some of them are being rediscovered through a process of careful clearing, which tries to keep the character of the cemetery. The ivy has been removed from some of these headstones - not only to protect them from decay - but also to allow them to be mapped digitally for the first time.

今天，在試圖保持墓地特征的基礎上，通過認真仔細的清理后，一些墓碑重新露出。這些墓碑上的常春藤已經被清除，這不僅是為了保護它們免受腐蝕，也是為了讓它們能夠首次被繪制在電子地圖上。

This is Pete. His backpack uses lasers, which can't be seen, to take three hundred thousand measurements a second. It also has five cameras taking pictures constantly. The information is uploaded online, and eventually a digital map comes to life.

這是皮特。他的背包使用激光，這是看不到的，每秒測量30萬次。背包里還有五個攝像頭在不停地拍照。這些信息會被上傳到網上，最終一張電子地圖就生成了。

Tim Viney, Chairman, Atlantic Geomatics
Highgate is, as you can see, is a pretty tough location. From a mapping perspective, vegetation can be our biggest nightmare. There are paths - but there are also areas that are very difficult to access – so we have to be very careful from a health and safety perspective.

蒂姆·瓦伊尼              Atlantic Geomatics 公司主席
“海格特公墓，正如你所看到的，是一個非常難測量的地點。從繪制地圖的角度來說，植被是我們最怕遇到的東西。雖然這里有一些小路，但也有一些區域很難進入，所以從健康和安全的角度來說，我們必須非常小心。”

Over the last year, Tim and his team have now mapped more than half the cemetery. And already – the new system is helping.

去年，蒂姆和他的團隊已經把超過一半的墓地繪制進了電子地圖。這個新地圖已經開始起作用了。

Ian Dungavell , CEO, Friends of Highgate Cemetery Trust
It's wonderful that new technology can enable us to do this in a way that just isn't possible with old paper records.

伊恩·鄧加維爾             海格特公墓信托之友首席執行官
“令人驚嘆的是，新技術可以使我們做到這一點，而這是舊的紙質記錄無法做到的。”

Over the next year – there will be more mapping and only the most essential plant clearing, meaning more of this incredible part of London is accessible for generations to come.

在接下來的一年里，繪制地圖的工作仍將繼續，只有必須要清理的植物才會被清除，這意味著倫敦這片美麗的區域將會有更多的地方可供后人使用。
