ABOUT THE SPEAKER
Chance Coughenour - Digital archaeologist
Chance Coughenour is recreating heritage and culture that's been lost throughout the world.

Why you should listen

Chance Coughenour enjoys the innovations made possible by uniting science and archaeological research, which was part of the inspiration in the founding of Rekrei. His previous work on a EU-funded project connected him with Matthew Vincent, an archaeologist and web developer, who together launched Rekrei (formally Project Mosul) on March 8 of 2015 after witnessing the destruction of heritage in northern Iraq. Their open-source, volunteer initiative strives for the digital reconstruction of lost heritage using crowdsourced images and photogrammetry, the process of using 2D images to create 3D models.

From the start, Rekrei aimed to crowdsource the virtual reconstruction of the destroyed objects in the Mosul Cultural Museum and eventually release a virtual museum to digitally preserve its memory. This has already been accomplished thanks to the Economist Media Lab. The project has also expanded globally and continues to increase its activities thanks to our growing collaboration with public and private organizations, all of which has been achieved without any funding resources to date. The key ingredient to Rekrei is the online platform, which provides a simple user interface for identifying locations of destroyed heritage, uploading and sorting images, and a 3D gallery of completed reconstructions.

Coughenour has worked on research projects throughout Europe and the Americas. One of which is demonstrated in the documentary Scanning the End. He is a PhD candidate at the Institute for Photogrammetry at the University of Stuttgart. Coughenour joined Google Arts & Culture where he coordinates cultural heritage preservation efforts on a global scale. He's responsible for organizing partnerships and leading projects which employ emerging technology for cultural heritage documentation, dissemination and education.

他们相信
00:19
do they believe
they're erasing擦除 our history历史?

这么做就能抹掉历史,
抹掉我们的文化记忆吗?
00:23
Our cultural文化 memory记忆?

00:26
It's true真正 that we are losing失去
cultural文化 heritage遗产 to erosion侵蚀
4
14570
4677
事实上,侵蚀和自然灾害
00:31
and natural自然 disasters灾害,
5
19271
1809
正让我们失去文化遗产,
00:33
but this is something
that is simply只是 difficult to avoid避免.
6
21104
2934
但这个过程是难免的。
00:36
I'm here to show显示 you today今天
how we can use pictures图片 --
7
24876
4106
我今天来向你们展示,
我们如何运用照片——
00:41
your pictures图片 --
8
29006
1858
你们的照片-——
00:42
to reclaim回收 the history历史 that is being存在 lost丢失
9
30888

来重建失去的历史,
00:46
using运用 innovative创新 technology技术
10
34032
2223
通过创新科技
和志愿者的努力。
00:48
and the effort功夫 of volunteers志愿者.

In the early 20th century世纪,
12
40182
2021
20世纪初,
00:54
archaeologists考古学家 discovered发现
hundreds数以百计 of statues雕像 and artifacts文物
13
42227
3988
考古学家在伊拉克北部的哈特拉古城
00:58
at the ancient city of HatraHatra,
14
46239
1734
发现了数百件的
00:59
in northern北方 Iraq伊拉克.
15
47997
1150
雕像和文物。
01:01
Statues雕像 like this one
were found发现 in fragments片段,
16
49976
3781
这样的雕像被发现时已经支离破碎,
01:05
some of them missing失踪 their heads or arms武器,
17
53781
3137
有些失去了头和手臂,
01:08
yet然而 the clothing服装 that they are wearing穿着
18
56942
2513
但是他们的衣着,
01:11
and their pose提出
19
59479
1446
还有身体的姿态,
01:12
can still tell us their story故事.
20
60949
2283
仍然能够诉说他们的故事。
01:16
For example,
21
64239
1150
比如,
01:17
we believe that by wearing穿着
a knee-length及膝 tunic中山装
22
65413
3734
我们知道穿过膝长袍,
01:21
and open打开 bare feet,
23
69171
1500
赤足,
表明这是一位牧师。
01:22
this was representative代表 of a priest牧师.
24
70695
2581
01:25
However然而, with a closer接近 look
at this particular特定 piece,
25
73962
3821
然而,仔细看细节部分,
01:29
we can see that this tunic中山装 being存在 worn磨损的
was elaborately精心 decorated装饰,
26
77807
4422
这是一件精心雕饰的长袍,
01:34
which哪一个 has led many许多 researchers研究人员 to believe
27
82253
2822
许多研究人员由此相信,
01:37
this was actually其实 a statue雕像 of a king国王
performing执行 his religious宗教 functions功能.
28
85099
3873
这是一个履行宗教职能的
国王的雕像。
01:43
When the Mosul摩苏尔 Cultural文化 Museum博物馆
opened打开 in 1952 in northern北方 Iraq伊拉克,
29
91126
6071
1952年,摩苏尔文化博物馆
在北伊拉克开馆,
这尊雕塑,还有其他的一些文物
01:49
this statue雕像, as well as others其他,
30
97221
2247
被陈列出来加以保存,以供后代观赏。
01:51
were placed放置 there to preserve保留 them
for future未来 generations.
31
99492
3164
01:56
Following以下 the US-led以美国为首的 invasion侵入
of Iraq伊拉克 in 2003,
32
104265
3939
2003年美国入侵伊拉克后,
02:00
a few少数 statues雕像 and artifacts文物
were relocated搬迁 to Baghdad巴格达,
33
108228
3865
少数雕塑和文物被转移到巴格达,
02:04
but this statue雕像 remained保持.
34
112117
2075
但是这尊雕塑仍然留在那里。
02:07
Then in February二月 of last year,
a video视频 was released发布,
35
115446
3760
去年2月,网上出现了一个视频,
立刻获得了大量点击。
02:11
and it instantly即刻 went viral病毒.
36
119230
2401
02:14
Maybe some of you remember记得 seeing眼看 it.
37
122075
2271
可能你们中有人看过。
02:16
Here's这里的 a short clip.
38
124370
1533
这是其中的一个片段。
02:17
(Video视频) (Singing唱歌 in Arabic阿拉伯)
39
125927
6900
(录像)(阿拉伯语歌曲)
02:43
(Singing唱歌 ends结束)
40
151573
1216
(歌声结束)
02:46
Not a very pleasant愉快 sight视力, right?
41
154107
2392
不太愉快的景象吧?
02:49
Did you notice注意 anything
familiar in the video视频?
42
157679
2640
看到什么熟悉的东西了吗?
02:53
There it is.
43
161552
1503
就是它。
02:55
There is that very statue雕像,
44
163079
2672
就是这尊雕塑,
02:57
as it was toppled扳倒 over,
45
165775
1743
被推翻,
02:59
breaking破坏 into pieces.
46
167542
1520
摔成了碎片。
03:01
When Matthew马修 Vincent文森特 and I saw this video视频,
47
169976
2861
当Matthew Vincent 和我
看到这个录像时,
03:04
we were shocked吃惊.
48
172861
1268
都惊呆了。
03:07
Since以来 we are archaeologists考古学家
using运用 innovative创新 technology技术
49
175059
3428
我们是运用创新科技对文物
进行数字保存的
03:10
for digital数字 preservation保存,
50
178511
1790
考古学家,
于是突然有了一个想法。
03:12
an idea理念 sprung弹性 to mind心神.
51
180325
1559
03:14
Maybe we can crowdsource众包 the images图片
that were taken采取 of these artifacts文物
52
182502
4813
也许我们可以面向大众搜集
文物被破坏前的图像,
03:19
before they were destroyed销毁,
53
187339
1815
用来重造数字影像。
03:21
to create创建 digital数字 reconstructions重建.
54
189178
1943
03:23
If we can do that,
55
191765
1150
如果我们成功了,
03:24
maybe we can put them
into a virtual虚拟 museum博物馆
56
192939
2091
就可以把成果加入到虚拟博物馆,
03:27
to tell that story故事.
57
195054
1234
继续述说它们的故事。
03:32
And so two weeks after we saw this video视频,
58
200030
3504
在看到录像的两周后,
03:35
we started开始 the project项目
called Project项目 Mosul摩苏尔.
59
203558
3139
我们开始了一个项目,
叫做“摩苏尔计划”。
03:40
Remember记得 the pictures图片 of the statue雕像
I showed显示 you before?
60
208328
2773
还记得之前给大家看的
雕塑的图片吗?
03:43
This is actually其实 the crowdsourced众包
reconstruction重建 of it
61
211471
4377
它实际上就是通过
众筹图片重新创造出的
03:47
before it was destroyed销毁.
62
215872
1605
它被破坏前的样子。
03:50
Now, many许多 of you may可能 be wondering想知道,
63
218776
2123
你们当中有人一定在想,
03:52
how exactly究竟 does this work?
64
220923
1738
到底怎么做到的?
03:54
Well, the key to this technology技术
is called photogrammetry摄影,
65
222966
3375
其中运用的主要技术
叫做摄影测绘学,
03:58
and it was invented发明 here, in Germany德国.
66
226365
2456
这项技术就诞生在德国。
04:01
It is the technology技术 that allows允许 us
to use two-dimensional二维 images图片
67
229890
3406
它允许我们用从同一物体的
04:05
taken采取 of the same相同 object目的
from different不同 angles
68
233320
2949
不同角度获得的二维图片
04:08
to create创建 a 3D model模型.
69
236293
1395
创造出3D模型。
04:11
I know you may可能 be thinking思维
this sounds声音 like magic魔法 -- but it's not.
70
239269
4199
听起来很神奇吧?
不过这可不是什么魔法。
04:15
Let me show显示 you how it works作品.
71
243492
1531
我来解释一下它的工作原理。
04:17
Here are two crowdsourced众包 images图片
of the same相同 statue雕像.
72
245047
2771
这是两张同一雕塑的图片。
04:20
What the computer电脑 can do
73
248928
1395
计算机能够
04:22
is it can detect检测 similar类似 features特征
between之间 the photographs照片 --
74
250347
4215
发现相片中相似的部分——
04:26
similar类似 features特征 of the object目的.
75
254586
2033
目标体上相似的部分。
04:29
Then, by using运用 multiple photos相片,
76
257569
2976
然后用多个图像
04:32
in this case案件, it can begin开始
to reconstruct重建 the object目的 in 3D.
77
260569
3728
重新创造出物体的3D影像。
04:36
In this case案件,
78
264815
1150
在这个例子中,
拍摄图像的照相机的不同位置
04:37
you have the position位置 of the cameras相机
when each image图片 was taken采取,
79
265989
3432
用蓝色区域进行了标记。
04:41
shown显示 in blue蓝色.
80
269445
1178
04:44
Now, this is a partial局部
reconstruction重建, I admit承认,
81
272282
3414
我承认这只是部分重建,
04:47
but why would I say partial局部?
82
275720
1592
为什么说是部分呢?
04:49
Well, simply只是 because the statue雕像
was positioned定位的 against反对 a wall.
83
277617
4679
因为雕塑是靠墙摆放的,
04:54
We don't have photographs照片
taken采取 of it from the back.
84
282871
2603
我们没有从后往前拍摄的图片。
04:58
If I wanted to complete完成 a full充分
digital数字 reconstruction重建 of this statue雕像,
85
286339
4952
如果要完成整个雕塑重造,
05:03
I would need a proper正确 camera相机,
86
291315
1709
我们需要合适的相机,
05:05
tripods三脚架, proper正确 lighting灯光,
87
293048
1745
三脚架,适当光线,
05:06
but we simply只是 can't do that
with crowdsourced众包 images图片.
88
294817
2490
而这些并不能通过众筹得到。
05:10
Think about it:
89
298149
1150
思考一下:
你们中有多少人在参观博物馆时,
05:11
How many许多 of you, when you visit访问 a museum博物馆,
90
299323
2233
会对一个雕塑进行
全方位无死角的拍摄,
05:13
take photographs照片
of all parts部分 of the statue雕像,
91
301580
2241
包括从背后?
05:15
even the back side of it?
92
303845
1465
05:18
Well, maybe if some of you find
Michelangelo's米开朗基罗 David大卫 interesting有趣,
93
306406
3597
也许你们中有人会觉得
米开朗基罗的大卫雕像挺有趣。
05:22
I guess猜测 --
94
310027
1151
我猜的没错吧——
(笑)
05:23
(Laughter笑声)
95
311202
1484
05:25
But the thing is,
96
313168
1489
事实是,
如果我们能得到更多
目标物的图像,
05:26
if we can find more images图片 of this object目的,
97
314681
3140
05:29
we can improve提高 the 3D model模型.
98
317845
1624
就优化3D模型。
05:33
When we started开始 the project项目,
99
321133
2174
在这个项目启动之初,
05:35
we started开始 it with
the Mosul摩苏尔 Museum博物馆 in mind心神.
100
323331
2149
我们从摩苏尔博物馆开始。
想着也许可以得到
一些人感兴趣的
05:37
We figured想通 we may可能 get a few少数 images图片,
101
325504
1667
少量图像,
05:39
some people interested有兴趣,
102
327195
1246
完成一两个虚拟重建,
05:40
make one or two virtual虚拟 reconstructions重建,
103
328465
2479
但我们根本没有预料到
事情的发展如此神速。
05:42
but we had no idea理念 that we had sparked引发
something that would grow增长 so quickly很快.
104
330968
4759
05:48
Before we knew知道 it,
105
336276
1553
之前
05:49
we realized实现 it was obvious明显:
106
337853
2031
我们就意识到:
05:51
we could apply应用 this same相同 idea理念
to lost丢失 heritage遗产 anywhere随地.
107
339908
3904
我们可以把这个点子
用于任何失去的文物。
05:56
And so, we decided决定 to change更改
the name名称 of the project项目 to RekreiRekrei.
108
344559
4015
我们决定把项目
重新命名为Rekrei。
06:02
Then, in the summer夏季 of last year,
109
350007
2520
去年夏天,
《经济学人》杂志的
媒体实验室联系了我们。
06:04
"The Economist经济学家" magazine's杂志 media媒体 lab实验室
reached到达 out to us.
110
352551
3040
06:08
They asked us,
111
356673
1174
他们问道,
06:09
"Hey, would you like us
to build建立 a virtual虚拟 museum博物馆
112
357871
2767
“需不需要我们建立
一个虚拟博物馆,
把重塑后的物品装在里面,
06:12
to put the reconstructions重建 back inside,
113
360662
1865
述说它们的故事?“
06:14
to tell the story故事?"
114
362551
1280
06:16
Can you imagine想像 us saying no?
115
364198
1770
我们怎么可能拒绝呢?
当然不能!
06:17
Of course课程 not.
116
365992
1301
于是我们同意了。
06:19
We said yes!
117
367317
1151
我们都兴奋不已。
06:20
We were so excited兴奋.
118
368492
1157
这正是建立项目的最初梦想。
06:21
This was exactly究竟
the initial初始 dream梦想 of that project项目.
119
369673
3180
06:25
And so now,
120
373662
1187
现在,
每个人都可以通过手机
体验 RecoVR Mosul,
06:26
any of you can experience经验
RecoVRRecoVR Mosul摩苏尔 on your phone电话,
121
374873
3614
可以借助Google Cardboard,
06:30
using运用 Google谷歌 Cardboard纸板
122
378511
1293
06:31
or a tablet片剂 or even YouTubeYouTube的 360.
123
379828
2647
或者平板电脑,
甚至 YouTube 360。
06:35
Here is a screenshot截图
from the virtual虚拟 museum博物馆.
124
383044
3456
这是虚拟博物馆的截屏。
看见了吗?
06:38
And there it is ...
125
386524
1150
06:40
the partial局部 reconstruction重建 of the statue雕像,
126
388311
2498
(中间的就是)
这个雕塑的部分复原影像,
06:42
as well as the Lion狮子 of Mosul摩苏尔,
127
390833
2867
还有摩苏尔之狮,
06:45
the first reconstruction重建
completed完成 by our project项目.
128
393724
2672
这是我们的项目
完成的第一个作品。
06:49
Although虽然 the video视频 doesn't explicitly明确地 show显示
the Lion狮子 of Mosul摩苏尔 being存在 destroyed销毁,
129
397539
4790
虽然录像中并没有显示
摩苏尔之狮被毁掉了,
但我们有很多其他
被毁掉的大型文物,
06:54
we have many许多 other examples例子
of large artifacts文物 being存在 destroyed销毁
130
402353
4133
因为体积太大而没有被偷走。
06:58
that were simply只是 too large
to have been stolen被盗.
131
406510
3141
07:02
For example,
132
410172
1363
例如,
伊拉克北部的尼姆门。
07:03
the Gate of Nimrud尼姆鲁德 in northern北方 Iraq伊拉克.
133
411559
2786
07:06
This is a digital数字
reconstruction重建 from before,
134
414657
2859
这是对从前形貌的数字还原,
这是它被破坏后的样子。
07:09
and this is actually其实
during the destruction毁坏.
135
417540
3365
07:13
Or the Lion狮子 of Al-L铝升āt, in Palmyra巴尔米拉, Syria叙利亚:
136
421406
3620
还有AI-Lāt之狮,
位于叙利亚巴尔米拉:
07:17
before ...
137
425050
1150
从前——
07:18
and after.
138
426901
1150
还有现在。
07:21
Although虽然 virtual虚拟 reconstructions重建
are primarily主要 the main主要 focus焦点
139
429546
3270
虽然虚拟重建是我们项目的
重点,
07:24
of our project项目,
140
432840
1182
有人还是会问我们:
07:26
some people have been asking the question:
141
434046
2063
07:28
Can we print打印 them in 3D?
142
436534
3396
能打印出3D模型吗?
07:32
We believe 3D printing印花
doesn't offer提供 a straightforward直截了当 solution
143
440555
4257
我们并不认为3D打印
能够针对失去的文物提供直接的
解决方案。
07:36
to lost丢失 heritage遗产.
144
444836
1190
07:38
Once一旦 an object目的 is destroyed销毁,
145
446338
1949
一旦物体被毁坏了,
07:40
it's gone走了.
146
448311
1150
就不存在了。
07:42
But 3D printing印花 does offer提供
an addition加成 to tell that story故事.
147
450052
5027
但是,3D打印的确能够帮助
我们讲述这些故事。
07:47
For example, I can show显示 you here ...
148
455739
2355
比如,给大家展示一下——
07:53
There is the statue雕像 from HatraHatra
149
461660
2914
这是哈特拉和
摩苏尔之狮的雕塑。
07:56
and the Lion狮子 of Mosul摩苏尔.

08:05
Thank you.
152

1150
谢谢。
如果你仔细观察,
08:07
Now, if you look closely密切,
153
475044
1504
08:08
you'll你会 notice注意 that there are some parts部分
that have been printed印刷的 in color颜色,
154
476572
4507
会发现有的部分带有颜色,
08:13
and some parts部分 that are in white白色 or gray灰色.
155
481103
2583
而有些部分呈白色或者灰色。
08:16
This part部分 was added添加
simply只是 to hold保持 the statues雕像 up.
156
484715
3802
这部分起到了加固雕塑的作用。
如果你参观博物馆,看到是一样的
08:20
This works作品 the same相同 way
if you visit访问 a museum博物馆,
157
488834
2427
08:23
and a statue雕像 is found发现 in fragments片段;
158
491285
2281
碎片状的雕塑:
人们看到是重新组合过的雕塑。
08:25
it's put together一起
for the people to see it.
159
493590
2270
08:27
This makes品牌 sense, right?
160
495884
1456
理解了吗?
08:30
However然而, we're much more interested有兴趣
161
498521
1753
不过,更让我们感兴趣的是
08:32
in what virtual虚拟 reality现实
has to offer提供 for lost丢失 heritage遗产.
162
500298
3395
虚拟现实如何能重塑失去的文物。
08:36
Here is an example
of one of the tower tombs墓葬
163
504420
2501
还有一个在巴尔米拉被破坏了的
08:38
that was destroyed销毁 in Palmyra巴尔米拉.
164
506945

陵墓的例子。
运用 Sketchfab 的在线查看器,
08:40
Using运用 Sketchfab'sSketchfab 的 online线上 viewer观众,
165
508844
1954
可以看见我们重塑了
陵墓外墙的三个部分,
08:42
we can show显示 that we have reconstructed重建
three parts部分 of the exterior外观 of the tomb,
166
510822
5655
我们也有内部的图片,
08:48
but we also have photos相片 of the inside,
167
516501
1905
08:50
so we're beginning开始 to create创建
a reconstruction重建 of the wall
168
518430

正在着手重新打造墙体和
天花板。
08:53
and the ceiling天花板.

1151
还有自然灾害。

we're also losing失去 it to natural自然 disasters灾害.
174

这是尼泊尔加德满都
Durbar广场的3D模型,
09:18
before the earthquake地震
that occurred发生 last April四月 ...
176
546772
2650
这是去年4月发生地震前的样子,
09:22
and this is after.
177
550297
1250
这是地震后的景象。
09:24
You may可能 be thinking思维,
178
552563
1598
你们可能在想,
09:26
you didn't create创建 these 3D models楷模
with only tourist游客 photographs照片,
179
554185
3669
你们不会仅仅通过游客图片
来打造3D模型吧。
09:29
and that's true真正.
180
557878
1391
说对了。
不过这体现的是
09:31
But what this represents代表
181
559293
1476
与我们有着共同目标的
大公司,公共公司,私人公司
09:32
is the ability能力 for large, public上市
organizations组织 and private私人的 industry行业
182
560793
3746
09:36
to come together一起
for initiatives倡议 like ours我们的.
183
564563
2410
携手合作的能力。
09:41
And so one of the major重大的 challenges挑战
of our project项目, really,
184
569759
3088
我们的项目遇到的主要挑战
09:44
is to find photographs照片 that were taken采取
before something happens发生, right?
185
572871
3888
是找到灾难发生之前的图片,对吧?
09:49
Well, the internet互联网 is basically基本上 a database数据库
with millions百万 of images图片, right?
186
577620
6024
而互联网正是个基于
成百万图片的数据库,不是吗?
09:55
Exactly究竟.
187
583668
1351
没错。
于是我们着手开发了一个工具,
09:57
So we have begun开始 to develop发展 a tool工具
188
585043
3435
允许我们在类似Flickr
那样的网站上,基于地理标记
10:00
that allows允许 us to extract提取 images图片
from websites网站 like FlickrFlickr的,
189
588502
3922
10:04
based基于 on their geotags地理标记,
190
592448
1498
来提取图片,
完成重建。
10:05
to complete完成 reconstructions重建.
191
593970
1583
10:08
Because we're not only losing失去 cultural文化
heritage遗产 to natural自然 disasters灾害 and in war战争,
192
596396
6763
除了自然灾害和战争,
我们也会因为其他因素
10:15
but we're also losing失去 it
to something else其他.
193
603183
2969
失去文化遗产。
10:19
Any idea理念, just looking
at these two pictures图片?
194
607777
2531
还记得这两张图片吗?
10:23
Maybe it's a little difficult to remember记得,
195
611649
2640
很难想起来吧,
10:26
but only a few少数 weeks ago,
196
614313
2420
就在几星期前,
10:28
this was the example of human人的
destruction毁坏 by human人的 stupidity糊涂事.
197
616757
4610
它们被人类的愚蠢行为毁掉了。
10:33
Because a tourist游客 in Lisbon里斯本
wanted to climb onto this statue雕像
198
621949
5309
因为一个在里斯本的游客
企图爬上这个雕塑
跟它自拍——
10:39
and take a selfie自拍 with it --
199
627282
1365
(笑)
10:40
(Laughter笑声)
200
628671
1001
然后他们一起摔下来了。
10:41
and pulled it down with him.
201
629696
1532
10:43
So we're already已经 finding发现 photographs照片
202
631596
1989
我们已经在寻找相关图片
打算进行虚拟重建。
10:45
to complete完成 a digital数字
reconstruction重建 of this.
203
633609
2154
10:48
We need to remember记得
204
636974
1286
我们要时刻铭记,
10:50
that the destruction毁坏 of cultural文化 heritage遗产
isn't a recent最近 phenomenon现象.
205
638284
4547
破坏历史文物的行为
不是最近才有的。
10:55
In the 16th century世纪,

11:03
of which哪一个 we only have a handful少数 left.
208
651508
2513
只有少数保留至今。
11:07
Fast-forward快进 to 2001,
209

11:13
You see,
211
661754
1735
大家都知道,
文物是全球共享的历史。
11:15
cultural文化 heritage遗产
is about our shared共享 global全球 history历史.
212
663513
4067
11:20
It helps帮助 us connect
with our ancestors祖先 and their stories故事,
213
668820
3741
它帮助我们了解
自己的祖先和他们的故事,
我们每天都在自然灾害
和地区冲突中
11:24
but we're losing失去 pieces of it
every一切 day to natural自然 disasters灾害
214
672585
4271
失去宝贵的文物。
11:28
and in areas of conflict冲突.
215
676880
2286
11:32
Of course课程, the loss失利 of human人的 life
is the most heartbreaking令人心碎 loss失利 ...
216
680114

当然,最让人心疼的
是失去了人类生活的证据,
11:37
but cultural文化 heritage遗产 offers报价 us a way
to preserve保留 the memory记忆 of the people
217
685742
5836
文物能为我们
提供线索,并为后代
11:43
for future未来 generations.

ABOUT THE SPEAKER
Chance Coughenour - Digital archaeologist
Chance Coughenour is recreating heritage and culture that's been lost throughout the world.

Why you should listen

Chance Coughenour enjoys the innovations made possible by uniting science and archaeological research, which was part of the inspiration in the founding of Rekrei. His previous work on a EU-funded project connected him with Matthew Vincent, an archaeologist and web developer, who together launched Rekrei (formally Project Mosul) on March 8 of 2015 after witnessing the destruction of heritage in northern Iraq. Their open-source, volunteer initiative strives for the digital reconstruction of lost heritage using crowdsourced images and photogrammetry, the process of using 2D images to create 3D models.

From the start, Rekrei aimed to crowdsource the virtual reconstruction of the destroyed objects in the Mosul Cultural Museum and eventually release a virtual museum to digitally preserve its memory. This has already been accomplished thanks to the Economist Media Lab. The project has also expanded globally and continues to increase its activities thanks to our growing collaboration with public and private organizations, all of which has been achieved without any funding resources to date. The key ingredient to Rekrei is the online platform, which provides a simple user interface for identifying locations of destroyed heritage, uploading and sorting images, and a 3D gallery of completed reconstructions.

Coughenour has worked on research projects throughout Europe and the Americas. One of which is demonstrated in the documentary Scanning the End. He is a PhD candidate at the Institute for Photogrammetry at the University of Stuttgart. Coughenour joined Google Arts & Culture where he coordinates cultural heritage preservation efforts on a global scale. He's responsible for organizing partnerships and leading projects which employ emerging technology for cultural heritage documentation, dissemination and education.
