virtual虚拟 worlds世界, digital数字 globes地球仪, the 3-D-D Web卷筒纸, the Metaverse虚拟实境.
1
3000
9000
虚拟世界,数字地球,三维网络和网络虚拟实境.
00:37
What does this all mean for us?
2
12000
2000
这些东西对于我们意味着什么?
00:39
What it means手段 is the Web卷筒纸 is going to become成为 an exciting扣人心弦 place地点 again.
3
14000
5000
这意味着网络又将变成一个令人激动的地方.
00:44
It's going to become成为 super exciting扣人心弦 as we transform转变

00:51
With graphics图像, computing计算 power功率, low latencies潜伏期,
6
26000
3000
这个拥有各种图形,高计算能力和低延迟的世界.
00:54
these types类型 of applications应用 and possibilities可能性
7
29000
3000
这类的应用程序和它创造的可能性
00:57
are going to stream rich丰富 data数据 into your lives生活.
8
32000
5000
将把丰富的数据流带进你的生活.
01:02
So the Virtual虚拟 Earth地球 initiative倡议, and other types类型 of these initiatives倡议,
9
37000
5000
所以,虚拟地球的出现, 或者其它这种类型的程序的出现,
01:07
are all about extending扩展 our current当前 search搜索 metaphor隐喻.
10
42000
6000
都是关于扩展我们当前的搜索方法的.
01:13
When you think about it, we're so constrained受限 by browsing浏览 the Web卷筒纸,
11
48000
3000
思考一下,我们在浏览网络时总是被限制着.
01:16
remembering记忆 URLs网址, saving保存 favorites最爱.
12
51000
3000
记网址,保存到"我的最爱".
01:19
As we move移动 to search搜索, we rely依靠 on the relevance关联 rankings排名,
13
54000
3000
当搜索出现后,我们依赖于
01:22
the Web卷筒纸 matching匹配, the index指数 crawling爬行.
14
57000
3000
相关性排名,网络匹配和索引检索.
01:25
But we want to use our brain!
15
60000
2000
但我们要用我们的大脑!
01:27
We want to navigate导航, explore探索, discover发现 information信息.
16
62000
3000
我们要自己去航行,探索和发现信息.
01:30
In order订购 to do that, we have to put you as a user用户 back in the driver's司机 seat座位.
17
65000
5000
为了这样做,我们必须把用户放回驾驶员的座位上.
01:35
We need cooperation合作 between之间 you and the computing计算 network网络 and the computer电脑.
18
70000
4000
我们需要你与网络和计算机之间的合作.
01:39
So what better way to put you back in the driver's司机 seat座位
19
74000
4000
有什么更好的方法比把你放在驾驶员的座位上
01:43
than to put you in the real真实 world世界 that you interact相互作用 in every一切 day?
20
78000
3000
把你放在每天都接触的真实世界里还要好呢?
01:46
Why not leverage杠杆作用 the learnings学习收获 that you've been learning学习 your entire整个 life?
21
81000
4000
为什么不去利用你在生活中学过的知识呢?
01:50
So Virtual虚拟 Earth地球 is about starting开始 off
22
85000
3000
所以,虚拟地球是关于
01:53
creating创建 the first digital数字 representation表示, comprehensive全面, of the entire整个 world世界.
23
88000
5000
创造第一个数字表达的,综合的世界.
01:58
What we want to do is mix混合 in all types类型 of data数据.
24
93000
3000
我们要做的是混合所有类型的数据.
02:01
Tag标签 it. Attribute属性 it. Metadata元数据. Get the community社区 to add local本地 depth深度,
25
96000
5000
给它做上标记,加上属性和元数据. 理解本地社区并加上本地内容
02:06
global全球 perspective透视, local本地 knowledge知识.
26
101000
3000
-- 全球的视角, 本地的知识.
02:09
So when you think about this problem问题,
27
104000
2000
那么,当你思考这个问题的时候,
02:11
what an enormous巨大 undertaking承诺. Where do you begin开始?
28
106000
4000
这是多么大的一个任务. 你想, 从哪儿着手做呢?
02:15
Well, we collect搜集 data数据 from satellites卫星, from airplanes飞机,
29
110000
4000
我们通过卫星,飞机
02:19
from ground地面 vehicles汽车, from people.
30
114000
3000
地面车辆和人来采集数据.
02:22
This process处理 is an engineering工程 problem问题,
31
117000
5000
这是我们的方法, 你知道, 这是一个工程问题.
02:27
a mechanical机械 problem问题, a logistical后勤 problem问题, an operational操作 problem问题.
32
122000
4000
一个机械问题, 一个逻辑问题和一个运营问题.
02:31
Here is an example of our aerial天线 camera相机.
33
126000
2000
这是航空摄像机的一个例子.
02:33
This is panchromatic全色. It's actually其实 four color颜色 cones.
34
128000
3000
这是一个全色相机. 它其实有四个彩色锥体.
02:36
In addition加成, it's multi-spectral多光谱.
35
131000
2000
另外, 它是多光谱的.
02:38
We collect搜集 four gigabits吉比特 per second第二 of data数据,
36
133000
4000
我们每秒种可以采集到4GB的数据,
02:42
if you can imagine想像 that kind of data数据 stream coming未来 down.
37
137000
2000
如果你能想像这种数据流传输下来,
02:44
That's equivalent当量 to a constellation星座 of 12 satellites卫星 at highest最高 res水库 capacity容量.
38
139000
6000
那相当于一个12个卫星的星座用最高清分辨率拍摄的数据量.
02:50
We fly these airplanes飞机 at 5,000 feet in the air空气.
39
145000
4000
我们驾驶这些飞机到5000英尺的高空;
02:54
You can see the camera相机 on the front面前. We collect搜集 multiple viewpoints观点,
40
149000
3000
你可以看到前置摄像机. 我们选择
02:57
vantage华帝 points, angles, textures纹理. We bring带来 all that data数据 back in.
41
152000
6000
多视点, 有利位置, 角度, 结构. 我们把数据带回来.
03:03
We sit here -- you know, think about the ground地面 vehicles汽车, the human人的 scale规模 --
42
158000
4000
我们坐在这儿 -- 你知道, 关于地面车辆和人的比例.
03:07
what do you see in person? We need to capture捕获 that up close
43
162000
2000
你自己看到了什么? 我们需要近距离捕捉他们来建立一种
03:09
to establish建立 that what it's like-type像型 experience经验.
44
164000
4000
逼真的体验.
03:13
I bet赌注 many许多 of you have seen看到 the Apple苹果 commercials广告,
45
168000
4000
我想你们大多数人都看过Apple商业展广告,
03:17
kind of poking at the PC个人计算机 for their brilliance and simplicity简单.
46
172000
6000
有点嘲笑PC电脑来表现出他们的简洁和光辉.
03:23
So a little unknown未知 secret秘密 is --
47
178000
2000
那么, 一个不为人知秘密是 --
03:25
did you see the one with the guy, he's got the Web卷筒纸 cam凸轮?
48
180000
4000
你有没有看到一个带着网络摄像机的家伙?
03:29
The poor较差的 PC个人计算机 guy. They're duct taping录音 his head. They're just wrapping包皮 it on him.
49
184000
4000
这个可怜的PC男孩, 头上带着管子, 他们给他包装成那样儿.
03:33
Well, a little unknown未知 secret秘密 is his brother哥哥 actually其实 works作品 on the Virtual虚拟 Earth地球 team球队.
50
188000
4000
好, 一个不为人知的秘密是他的哥哥,其实在虚拟地球研发团队工作.
03:37
(Laughter笑声). So they've他们已经 got a little bit of a sibling兄弟 rivalry对抗 thing going on here.
51
192000
5000
(笑声). 那么, 那里表达一些兄弟之间对抗的东西.
03:42
But let me tell you -- it doesn't affect影响 his day job工作.
52
197000
2000
但我告诉你 -- 这没有影响他每天的工作.
03:44
We think a lot of good can come from this technology技术.
53
199000
3000
我们想像这个科技带来很多的好处.
03:47
This was after Katrina卡特里娜. We were the first commercial广告 fleet舰队 of airplanes飞机
54
202000
4000
这是在Katrina飓风之后. 我们曾是灾难区域里的
03:51
to be cleared清除 into the disaster灾害 impact碰撞 zone.
55
206000
3000
第一个商业飞行队.
03:54
We flew the area. We imaged成像 it. We sent发送 in people. We took pictures图片 of interiors内饰,
56
209000
5000
我们飞到那个区域,拍下照片, 发给大家. 我们在灾区深入拍摄图片.
03:59
disaster灾害 areas. We helped帮助 with the first responders反应, the search搜索 and rescue拯救.
57
214000
4000
我们帮助应急救生员, 搜索和营救.
04:03
Often经常 the first time anyone任何人 saw what happened发生 to their house was on Virtual虚拟 Earth地球.
58
218000
5000
常常是人们是首先通过虚拟地球看到他们房屋的情况.
04:08
We made制作 it all freely自如 available可得到 on the Web卷筒纸, just to --
59
223000
2000
我们通过网络把这些免费提供给所有人, 是为了 -- 你知道,
04:10
it was obviously明显 our chance机会 of helping帮助 out with the cause原因.
60
225000
4000
这明显是我们为灾区人们提供帮助的机会.
04:14
When we think about how all this comes together一起,
61
229000
3000
当我们思考它时, 你知道, 这些东西如何组合到一起的.
04:17
it's all about software软件, algorithms算法 and math数学.
62
232000
4000
全是关于软件, 算法和数学.
04:21
You know, we capture捕获 this imagery意象 but to build建立 the 3-D-D models楷模
63
236000
3000
你知道, 我们捕捉图像,但是为了构建三维模型,
04:24
we need to do geo-positioning地理定位. We need to do geo-registering地理登记 of the images图片.
64
239000
5000
我们需要做地理定位. 我们需要做图片的地理标记.
04:29
We have to bundle adjust调整 them. Find tie领带 points.
65
244000
2000
我们必须收集调整他们. 找到联结点.
04:31
Extract提取 geometry几何 from the images图片.
66
246000
3000
完全是图像的几何学.
04:34
This process处理 is a very calculated计算 process处理.
67
249000
4000
这个过程完全是个计算的过程.
04:38
In fact事实, it was always doneDONE manual手册.
68
253000
1000
实际上, 几乎都是通过人工去计算的.
04:39
Hollywood好莱坞 would spend millions百万 of dollars美元 to do a small urban城市的 corridor走廊
69
254000
4000
好莱坞愿意花上百万美金去计算电影中的一个小市区走廊
04:43
for a movie电影 because they'd他们会 have to do it manually手动.
70
258000
3000
因为他们必须用手工计算.
04:46
They'd他们会 drive驾驶 the streets街道 with lasers激光器 called LIDARLIDAR.
71
261000
2000
他们用激光扫描探测技术在街道上驾驶.
04:48
They'd他们会 collected information信息 with photos相片. They'd他们会 manually手动 build建立 each building建造.
72
263000
4000
他们收集图片信息; 他们手工建造每个大楼.
04:52
We do this all through通过 software软件, algorithms算法 and math数学 --
73
267000
2000
我们做这些完全通过软件, 算法和数学.
04:54
a highly高度 automated自动化 pipeline管道 creating创建 these cities城市.
74
269000
3000
一个高度自动化的流水线来建造这些城市.
04:57
We took a decimal十进制 point off what it cost成本 to build建立 these cities城市,
75
272000
3000
我们在建造这些城市的费用上加一个小数点.
05:00
and that's how we're going to be able能够 to scale规模 this out and make this reality现实 a dream梦想.
76
275000
4000
这就是我们为什么能把规模做大并且将现实转化成虚拟.
05:04
We think about the user用户 interface接口.
77
279000
2000
我们考虑用户界面.
05:06
What does it mean to look at it from multiple perspectives观点?
78
281000
3000
采用多视角意味着什么?
05:09
An ortho-view邻视图, a nadir-view最低点视图. How do you keep the precision精确 of the fidelity保真度 of the imagery意象
79
284000
5000
一个鸟瞰视角, 一个垂直俯视. 你要如何保持图像的精度的同时
05:14
while maintaining维持 the fluidity流动性 of the model模型?
80
289000
4000
保持模型的流畅性?
05:18
I'll wrap up by showing展示 you the --
81
293000
2000
我会给你展示 --
05:20
this is a brand-new全新的 peek窥视 I haven't没有 really shown显示 into the lab实验室 area of Virtual虚拟 Earth地球.
82
295000
4000
这是个全新的俯视图我还没有放入虚拟地球的实验室区域.
05:24
What we're doing is -- people like this a lot,
83
299000
3000
我们要做的是 -- 人们喜欢这个
05:27
this bird's鸟类 eye imagery意象 we work with. It's this high resolution解析度 data数据.
84
302000
3000
我们要做的鸟瞰图. 是高解析度的数据.
05:30
But what we've我们已经 found发现 is they like the fluidity流动性 of the 3-D-D model模型.
85
305000
4000
但我们发现他们像三维模型的流畅度.
05:34
A child儿童 can navigate导航 with an Xbox的Xbox controller调节器 or a game游戏 controller调节器.
86
309000
4000
孩子们可以使用Xbox或游戏机去探索.
05:38
So here what we're trying to do is we bring带来 the picture图片 and project项目 it into the 3-D-D model模型 space空间.
87
313000
5000
这里,我们正尝试将图片映射到三维模型空间中.
05:43
You can see all types类型 of resolution解析度. From here, I can slowly慢慢地 pan the image图片 over.
88
318000
6000
你可以看到所有的分辨率. 从这里,我可以慢慢平移图像.
05:49
I can get the next下一个 image图片. I can blend混合 and transition过渡.
89
324000
3000
我可以看到下一张图片, 我可以结合和过渡.
05:52
By doing this I don't lose失去 the original原版的 detail详情. In fact事实, I might威力 be recording记录 history历史.
90
327000
5000
做这些操作时,我不会损失任何细节. 实际上,我有可能在记录历史.
05:57
The freshness新鲜, the capacity容量. I can turn this image图片.
91
332000
3000
新奇,能力. 我可以转动这个图像.
06:00
I can look at it from multiple viewpoints观点 and angles.
92
335000
3000
我可以查看多视点和多角度.
06:03
What we're trying to do is build建立 a virtual虚拟 world世界.
93
338000
3000
我们正在做的是, 打造一个虚拟世界.
06:06
We hope希望 that we can make computing计算 a user用户 model模型 you're familiar with,
94
341000
5000
我们希望可以计算出一个你熟悉的用户模型.
06:11
and really derive派生 insights见解 from you, from all different不同 directions方向.
95
346000
4000
可以从你的角度,从所有不同的角度浏览.
06:15
I thank you very much for your time.
