1、www.XiYuS锡育软件When we think of Nepal,we tend to think of the snow-capped mountains of the Himalayas,the crystal-clear stillwaters of its alpine lakes,or the huge expanse of itsgrasslands.想到尼泊尔,我们总是想到冰雪覆盖的 喜马拉雅山,还有高山湖泊中水晶般透明而平静的湖水,又或是那它广袤的草原。00:13What some of us may not realize is that in the Himalaya
2、nfoothills,where the climate is much warmer and thelandscape much greener,there lives a great diversity ofwildlife,including the one-horned rhinoceros,the Asianelephant and the Bengal tiger.但有些人也许没有意识到的是,在喜马拉雅山山麓,那里气候更加温暖,有更多的绿地,那里生活着种类繁多的野生动物,包括独角犀、亚洲象 和孟加拉虎。00:25But unfortunately,these animals are
3、 under constant threatfrom poachers who hunt and kill them for their body parts.但不幸的是,这些野生动物 一直以来都面临着偷猎者的威胁,这些偷猎者为了获取?而捕杀它们。00:43To stop the killing of these animals,battalions of soldiers andrangers are sent to protect Nepals national parks,but that isnot an easy task,because these soldiers have to
4、 patrolthousands of hectares of forests on foot or elephant backs.为了阻止这些偷猎行为,大量的士兵跟护林员 被派遣去保护尼泊尔的国家公园,但这并不是一个轻松的任务,因为这些士兵必须徒步 或者骑着大象 巡逻几千公顷的森林。00:51snow-capped:adj.积雪盖顶的 crystal-clear:adj.透明如水晶的;易懂的;非常清楚的 alpine:adj.阿尔卑斯山的,高山的expanse:n.宽阔;广阔的区域;苍天;膨胀扩张 grasslands:n.畜牧草原;大草原(grassland的复数形式)foothills:

6、th poachers,and therefore Nepal is always looking for newways to help with protecting the forests and wildlife.这也是一项危险的任务,因为他们可能会与偷猎者交火,所以,尼泊尔一直在寻找 保护森林与野生动物的 新方法。01:08Well recently,Nepal acquired a new tool in the fight againstwildlife crime,and these are drones,or more specifically,conservation dr
7、ones.最近,尼泊尔获得了一样新工具 用来对抗猎杀野生动物的罪行,这就是无人飞机,更确切地说,是环境保护无人机。01:20For about a year now,my colleagues and I have beenbuilding drones for Nepal and training the park protectionpersonnel on the use of these drones.在大约一年的时间中,我和我的同事 一直在为尼泊尔制造无人机,并培训公园保卫人员 如何使用这些无人机。01:30Not only does a drone give you a birds
8、-eye view of thelandscape,but it also allows you to capture detailed,high-resolution images of objects on the ground.无人机并不仅仅 给你鸟瞰的视野,它也可以捕捉到地面上细微的 高分辨率的物体的图像。01:39This,for example,is a pair of rhinoceros taking a cooling bathon a hot summer day in the lowlands of Nepal.例如,图中,炎热的夏天,一对犀牛正在尼泊尔的一处低地沼泽中
9、洗凉水澡。01:50Now we believe that drones have tremendous potential,notonly for combating wildlife crime,but also for monitoringthe health of these wildlife populations.我们相信,无人机具有 巨大的潜力,不只是用来对抗偷猎行为,也可以用来监察野生动物 的健康状况。01:59gunfights:n.枪战 fight against:v.对抗;反对;与作斗争 drones:n.雄蜂;(英)懒汉;遥控飞机(drone的复数形式)/v.混(日子)

11、ll,the kind of drone Im talking about is simply a modelaircraft fitted with an autopilot system,and this autopilotunit contains a tiny computer,a GPS,a compass,abarometric altimeter and a few other sensors.我正在谈论的这种无人机 简单来讲就是一种 搭载了自动驾驶仪的飞行器,这个自动驾驶仪包含了一个微型计算机,一个全球定位系统,一个指南仪,一个气压高度计,以及一些其他的传感器。02:12Now
12、 a drone like this is meant to carry a useful payload,suchas a video camera or a photographic camera.一个像这样的无人机 是用来载重有用的东西的,比如一个摄影机 或者一个照相机。02:29It also requires a software that allows the user to program a同时也需要一个软件给使用者 编写任务程序,来告诉无人机飞向哪里。02:37TED演讲者：Lian Pin Koh|Lian Pin Koh演讲标题：A drone.s-eye view of
13、 conservation|环境保护无人机的视野内容概要：Ecologist Lian Pin Koh makes a persuasive case for using drones to protect theworld.s forests and wildlife.These lightweight autonomous flying vehicles can track animals intheir natural habitat,monitor the health of rainforests,even combat crime by detectingpoachers via
14、thermal imaging.Added bonus?They.re also entirely affordable.生态学家Lian Pin Koh用有说服力的实例向我们讲述了如何用无人机保护地球上的森林和野生动物。这些轻巧的自动飞行器可以跟踪在自然栖息地里面的动物、监测热带雨林的健康状况、甚至用热成像技术侦测偷猎者以对抗偷猎行为。更不错的是，它们的价格非常有竞争力。It also requires a software that allows the user to program amission,to tell the drone where to go.诉无人机飞向哪里。02:3
15、7Now people I talk to are often surprised when they hear thatthese are the only four components that make a conservationdrone,but they are even more surprised when I tell themhow affordable these components are.当人们听到一架环境保护无人机 仅仅只有这四部分组成的时候,他们总是很惊奇,但当我告诉他们这些部件的价格 并不是那么贵的时候,他们显得更加惊讶。02:44The facts is,
16、a conservation drone doesnt cost very muchmore than a good laptop computer or a decent pair ofbinoculars.事实上,一架环境保护无人机 并不会比一台好的笔记本电脑,或者 一个像样的双目望远镜更加昂贵。02:57aircraft:n.飞机,航空器 fitted:adj.合适的;订做的;有设备的/v.适应(fit的过去分词);合适;为提供设备 autopilot:n.航自动驾驶仪(等于automaticpilot)barometric:adj.气压的 altimeter:n.测高仪,高度计 sen

18、它飞起来。但是如何使一架无人机飞起来呢？03:07Well,actually,you dont,because the drone flies itself.事实是,并不是你让它飞起来,因为,无人机自己就可以飞。03:14All you have to do is to program a mission to tell the dronewhere to fly.你所需要做的仅仅是设定一个任务,告诉无人机飞向哪里。03:18But you simply do that by clicking on a few way points onthe Google Maps interface us
19、ing the open-source software.但是你只需要在Google地图上 用开源软件 点击一些路径点。03:23Those missions could be as simple as just a few way points,orthey could be slightly longer and more complicated,to flyalong a river system.这些任务可以仅仅只是 简单的几个路径点,或者他们可以更长一些更加复杂一些,比如沿着河流飞行。03:31Sometimes,we fly the drone in a lawnmower-typ
20、e patternand take pictures of that area,and those pictures can beprocessed to produce a map of that forest.有时候,我们让无人机按照一个 除草机的路径飞行,为一片区域拍照,这些图片可以被处理 成为那片森林的地图。03:41Other researchers might want to fly the drone along theboundaries of a forest to watch out for poachers or peoplewho might be trying to
21、enter the forest illegally.其他的研究者,也许想要让无人机 沿着森林的边界飞行,来阻止偷猎者或者 其他试图非法进入森林的人。03:51Now whatever your mission is,once youve programmed it,you simply upload it to the autopilot system,bring yourdrone to the field,and launch it simply by tossing it in theair.不管你的目的是什么,一旦你设定了它,你只需要上传它到无人机的自动飞行系统,把你的无人机带到空旷

23、片,录制录像,通常这时候,我们就会给自己一杯咖啡,坐下,放松几分钟,04:12although some of us sit back and panic for the next fewminutes worrying that the drone will not return.尽管也会有人坐下后开始担忧 无人机会不会安全返航。04:25Usually it does,and when it does,it even lands automatically.通常它都能返航,它甚至可以自动着陆。04:31So what can we do with a conservation drone?
24、那么我们能用环境保护无人机做什么呢？04:36Well,when we built our first prototype drone,our mainobjective was to fly it over a remote rainforest in NorthSumatra,Indonesia,to look for the nest of a species of greatape known as the orangutan.当我们制造我们的第一架原型机时,我们的主要任务就是让它飞到 一片遥远的雨林,在印度尼西亚的北苏门答腊,去寻找一种大型猿类,即红毛猩猩的巢穴。04:39The r
25、eason we wanted to do that was because we needed toknow how many individuals of this species are still left in thatforest.我们这样做是因为 我们想知道在那片雨林中 还剩下多少只红毛猩猩。04:54Now the traditional method of surveying for orangutans isto walk the forest on foot carrying heavy equipment and touse a pair of binoculars t
26、o look up in the treetops where youmight find an orangutan or its nest.通常传统的搜寻红毛猩猩的方法 是带上沉重的装备 徒步穿越雨林,用双目望远镜在雨林顶端寻找,你可能会找到一只红毛猩猩,或者它的巢穴。05:02go about:v.着手做;四处走动;传开;从事 grab:vt.攫取;霸占;将深深吸引/vi.攫取;夺取/n.攫取;霸占;夺取之物 sit back:休息;不采取行动 automatically:adv.自动地;机械地;无意识地/adj.不经思索的 rainforest:n.(热带)雨林 Sumatra:n.气象

28、educe the cost of surveying fororangutan populations in Indonesia and elsewhere in你可以想象 这是一件多么耗费时间,耗费人力,多么昂贵的工程,所以我们希望无人机 能够极大地减少统计 在印度尼西亚和在其他东南亚地区的 红毛猩猩的数量的成本。05:17orangutan populations in Indonesia and elsewhere inSoutheast Asia.So we were very excited when we captured our first pair oforangutan n
29、ests on camera.所以当我们用相机找到第一对红毛猩猩巢穴的时候,我们非常兴奋。05:34And this is it;this is the first ever picture of orangutan neststaken with a drone.这就是那张照片,第一张用无人机拍摄的 红毛猩猩巢穴的照片。05:39Since then we have taken pictures of dozens of these nestsfrom around various parts of Southeast Asia,and were nowworking with comput
30、er scientists to develop algorithms thatcan automatically count the number of nests from thethousands of photos weve collected so far.我们在东南亚的不同地方 都拍到了很多 这样的巢穴的照片,现在我们正和计算机科学家们 一起开发计算方法,用我们已有的数千张照片自动计算 巢穴的数量。05:45But nests are not the only objects these drones can detect.但是,红毛猩猩巢穴,不是 无人机可以侦测到的唯一的东西。0

33、of the habitats these animals live in,because we want to keep track of the health of thesehabitats.但是除了拍摄野生动物的照片,我们也拍摄它们的栖息地,因为我们想要跟踪 这些栖息地的生态状况。06:27Sometimes,we zoom out a little and look at other things thatmight be happening in the landscape.有时候,我们会把画面缩小 来观察整个大环境 是否正在发生变化。06:39This is an oil pal
34、m plantation in Sumatra.这是一片苏门答腊的油棕榈种植园。06:45Now oil palm is a major driver of deforestation in that partof the world,so we wanted to use this new drone technologyto keep track of the spread of these plantations in SoutheastAsia.现在,在苏门答腊,油棕榈种植 是滥伐森林的主要推动力,所以我们想要用这种新的无人机技术 跟踪这些种植园 在东南亚的扩散。06:48But dr

37、ing part about taking picturesfrom the air is we could later stitch these pictures togetherusing special software to create a map of the entirelandscape,and this map gives us crucial information formonitoring land use change,但是在空中拍照 最激动人心的也许是,后期我们可以用特殊的软件把这些照片 拼合在一起,来制造一张全景地图,这张地图 可以给我们提供 监测土地使用状况的关
38、键信息,07:16to let us know where and when plantations might beexpanding,where forests might be contracting,or wherefires might be breaking out.让我们知道何时何地种植园也许正在扩张,哪里森林也许正在收缩,哪里也许有火灾。07:33Aerial images could also be processed to produce three-dimensional computer models of forests.这些航空图片 也可以被制作成森林的 三维电脑模
39、型。07:42www.XiYuS锡育软件Now these models are not just visually appealing,but theyare also geometrically accurate,which means researchers cannow measure the distance between trees,calculate surfacearea,the volume of vegetation,and so on,all of which areimportant information for monitoring the health of t
40、heseforests.这些模型不仅仅在视觉上吸引人,它们也非常精确,这就意味着,研究者们可以测量 树木之间的距离,计算表面积,植被体积等等,这些都是非常重要的数据,可以用来监测这些森林的生态状况。07:49planks:木木板 stitch:n.针脚，线迹；一针/vt.缝，缝合/vi.缝，缝合 contracting:adj.缔约的;承包的;收缩的 three-dimensional:adj.三维的;立体的;真实的 visually:adv.形象化地;外表上;看得见地 geometrically:adv.用几何学;几何学上地;按几何级数地 vegetation:n.植被;植物,草木;呆板单调
