Drevni spomenici odaju nam tragove zadivljujućih civilizacija iz prošlosti - ali njima prete zagađenje, rat, nemar. Ben Kacira, koji je izumeo revolucionaran sistem 3D skeniranja, koristi ovaj izum da skenira i sačuva svetsko nasleđe do detalja za arhivu. (Pogledate do kraja radi kratkog prikaza toga kako tehnologija radi.)

Želeo bih da počnem kratkom pričom -
00:16
I'd like to start with a short story.

00:20
It's about a little boy
1
5000
2000
o malom dečaku
00:22
whose father was a history buff
2
7000
5000
čiji je otac bio ljubitelj istorije
00:27
and who used to take him by the hand
3
12000
2000
koji ga je vodio za ruku
00:29
to visit the ruins of an ancient metropolis
4
14000
4000
da posete ruševine drevnih metropola
00:33
on the outskirts of their camp.
5
18000
3000
lociranim na obodima njihovog kampa.
00:36
They would always stop by to visit
6
21000
3000
Uvek bi zastali da posete
00:39
these huge winged bulls that used to guard
7
24000
3000
te ogromne krilate bikove
koji su čuvali
koji su čuvali
00:42
the gates of that ancient metropolis,
8
27000
2000
kapije te drevne metropole,
00:44
and the boy used to be scared
9
29000
2000
i dečaka su plašili
00:46
of these winged bulls,
10
31000
2000
ovi krilati bikovi,
00:48
but at the same time they excited him.
11
33000
2000
međutim, u isto vreme
su ga i oduševljavali
su ga i oduševljavali
00:50
And the dad used to use those bulls
12
35000
2000
I otac je uz te bikove
00:52
to tell the boy stories about
13
37000
2000
pričao priče dečaku
00:54
that civilization and their work.
14
39000
4000
o toj civilizaciji i njenom radu.
00:58
Let's fast-forward to the

Hajde da premotamo
do Zalivske oblasti San Franciska
mnogo decenija kasnije,
mnogo decenija kasnije,
01:01
San Francisco Bay Area many decades later,
16
46000
3000
01:04
where I started a technology company
17
49000
3000
gde sam osnovao
tehnološku kompaniju
tehnološku kompaniju
01:07
that brought the world its first
18
52000
3000
koja je svetu donela njegov prvi
01:10
3D laser scanning system.
19
55000
2000
3D sistem laserskog skeniranja.
01:12
Let me show you how it works.
20
57000
2000
Da vam pokažen kako on radi.
01:14
Female Voice: Long range laser scanning
21
59000
2000
Ženski glas: Dalekometno
lasersko skeniranje
lasersko skeniranje
01:16
by sending out a pulse that's a laser beam of light.
22
61000
3000
odašiljava puls
koji je laserski zrak svetlosti.
koji je laserski zrak svetlosti.
01:19
The system measures the beam's time of flight,
23
64000
2000
Sistem meri vreme kretanja zraka,
01:21
recording the time it takes for the light
24
66000
2000
pritom beležeći vreme potrebno da svetlost
01:23
to hit a surface and make its return.
25
68000
3000
udari u neku površinu i vrati se nazad.
01:26
With two mirrors, the scanner calculates
26
71000
2000
Sa dva ogledala, skener računa
01:28
the beam's horizontal and vertical angles,
27
73000
3000
horizontalne i vertikalne uglove zraka,
01:31
giving accurate x, y, and z coordinates.
28
76000
3000
određujući precizne „x”,
„y” i „z” koordinate.
„y” i „z” koordinate.
01:34
The point is then recorded
29
79000
2000
Tačka se potom zabeležava
01:36
into a 3D visualization program.
30
81000
5000
u 3D program vizualizacije.
01:41
All of this happens in seconds.
31
86000
3000
Sve ovo se dešava
u roku od nekoliko sekundi.
u roku od nekoliko sekundi.
01:46
Ben Kacyra: You can see here,
32
91000
2000
Ben Kacira: Možete da vidite
da su ovi sistemi izuzetno brzi.
01:48
these systems are extremely fast.
33
93000
3000
Oni sakupljaju milione tačaka u trenutku
01:51
They collect millions of points at a time
34
96000
3000
uz veoma visoku tačnost
01:54
with very high accuracy
35
99000
2000
i veoma visoku rezoluciju.
01:56
and very high resolution.
36
101000
2000
Istraživač koji koristi
tradicionalne istraživačke alatke
tradicionalne istraživačke alatke
01:58
A surveyor with traditional survey tools
37
103000
3000
02:01
would be hard-pressed to produce
38
106000
2000
teško bi mogao da napravi
02:03
maybe 500 points in a whole day.
39
108000
3000
možda 500 tačaka za ceo dan.
02:06
These babies would be producing
40
111000
3000
Ove bebice možda proizvode
otprilike deset hiljada tačaka po sekundi.
02:09
something like ten thousand points a second.
41
114000
3000
Dakle, kao što možete da zamislite,
02:12
So, as you can imagine,
42
117000
2000
ovo je bila smena paradigmi
02:14
this was a paradigm shift
43
119000
3000
u oblastima istraživanja i izgradnje
02:17
in the survey and construction
44
122000
2000
kao i u industriji snimanja stvarnosti.
02:19
as well as in reality capture industry.
45
124000
3000
02:26
Approximately ten years ago,
46
131000
3000
Pre otprilike deset godina,
moja žena i ja
smo osnovali fondaciju
smo osnovali fondaciju
02:29
my wife and I started a foundation to do good,
47
134000
3000
da činimo dobro
02:32
and right about that time,
48
137000
2000
i baš u to vreme,
02:34
the magnificent Bamiyan Buddhas,
49
139000
3000
Veličanstvene Bude iz Bamjana,
55 metara visoke, u Avganistanu,
02:37
hundred and eighty foot tall in Afghanistan,
50
142000
3000
02:40
were blown up by the Taliban.
51
145000
3000
digli su u vazduh Talibani.
Nestale su u trenutku.
02:43
They were gone in an instant.
52
148000
2000
I nažalost, nije postojala
02:45
And unfortunately, there was
53
150000
2000
detaljna dokumentacija o ovim Budama.
02:47
no detailed documentation of these Buddhas.
54
152000
2000
02:49
This clearly devastated me,
55
154000
2000
Ovo me je očigledno uništilo,
02:51
and I couldn't help but wonder about
56
156000
2000
i nisam mogao a da se ne zapitam
02:53
the fate of my old friends, the winged bulls,
57
158000
3000
o sudbini moji starih prijatelja,
krilatih bikova,
02:56
and the fate of the many, many
58
161000
3000
I o sudbini mnogo, mnogo
02:59
heritage sites all over the world.
59
164000
3000
baština širom sveta.
03:02
Both my wife and I
60
167000
2000
I moja žena i ja
bili smo toliko pogođeni ovim
03:04
were so touched by this
61
169000
2000
03:06
that we decided to
62
171000
2000
da smo odlučili
03:08
expand the mission of our foundation
63
173000
3000
da proširimo misiju izvan
naše fondacije
naše fondacije
03:11
to include digital heritage preservation
64
176000
4000
i da uključimo očuvanje digitalne baštine
03:15
of world sites.
65
180000
2000
svetskih lokacija.
03:17
We called the project CyArk,
66
182000
3000
Nazvali smo projekat - SajArh,
Što je skraćeno od Sajber Arhiva.
03:20
which stands for Cyber Archive.
67
185000
2000
03:22
To date, with the help of
68
187000
2000
Do danas, uz pomoć
03:24
a global network of partners,
69
189000
3000
globalne mreže partnera,
03:27
we've completed close to fifty projects.
70
192000
2000
završili smo skoro pedeset projekata.
03:29
Let me show you some of them:
71
194000
2000
Da vam pokažem neke od njih:
03:31
Chichen Itza,
72
196000
2000
Čičen Ica,
03:33
Rapa Nui --
73
198000
2000
Rapa Nui -
03:35
and what you're seeing here
74
200000
2000
i ono što vidite ovde
03:37
are the cloud of points --
75
202000
2000
su oblaci tačaka -
03:39
Babylon,
76
204000
2000
Vavilona,
Kapele Rozlin,
03:41
Rosslyn Chapel,
77
206000
2000
Pompeja
03:43
Pompeii,
78
208000
2000
i našeg najnovijeg projekta, Maunt Rašmor
03:45
and our latest project, Mt. Rushmore,
79
210000
2000
03:47
which happened to be one of
80
212000
2000
koji je igrom slučaja jedan
od naših najzahtevnijih projekata.
03:49
our most challenging projects.
81
214000
2000
Kao što vidite ovde,
morali smo da osmislimo
morali smo da osmislimo
03:51
As you see here, we had to develop
82
216000
2000
03:53
a special rig to bring the scanner
83
218000
3000
posebnu opremu koja će osigurati
da skeniranje
03:56
up close and personal.
84
221000
3000
bude izbliza i lično.
03:59
The results of our work in the field
85
224000
3000
Rezultati našeg rada u oblasti
se koriste da proizvedu
04:02
are used to produce
86
227000
2000
04:04
media and deliverables to be used
87
229000
2000
sredstva i predmete isporuke
koje će koristiti
koje će koristiti
04:06
by conservators and researchers.
88
231000
3000
konzervatori restauratori i istraživači.
Takođe proizvodimo sredstva
04:09
We also produce media for
89
234000
4000
04:13
dissemination to the public --
90
238000
3000
za razglašavanje publici -
04:16
free through the CyArk website.
91
241000
3000
besplatno preko SajArh vebsajta.
04:19
These would be used for education,
92
244000
3000
Oni se koriste za obrazovanje,
kulturalni turizam, itd.
04:22
cultural tourism, etc.
93
247000
2000
04:24
What you're looking at in here
94
249000
2000
Ono što ovde vidite
04:26
is a 3D viewer that we developed
95
251000
3000
je 3D čitač koji smo razvili
tako da dozvoli prikaz
04:29
that would allow the display
96
254000
2000
i upravljanje oblakom tačaka
04:31
and manipulation of [the] cloud of points
97
256000
2000
u realnom vremenu,
sečenjem sekcija kroz njih
sečenjem sekcija kroz njih
04:33
in real time, cutting sections through them
98
258000
3000
04:36
and extracting dimensions.
99
261000
2000
i vađenjem dimenzija.
Ovo je oblak tačaka
04:38
This happens to be the cloud of points
100
263000
2000
za Tikal.
04:40
for Tikal.
101
265000
1000
Ovde vidite tradicionalan 2D
04:41
In here you see a traditional 2D
102
266000
2000
04:43
architectural engineering drawing
103
268000
2000
arhitektonski crtež
04:45
that's used for preservation, and of course
104
270000
3000
koji se koristi za očuvanje, i naravno
mi pričamo priče uz pomoć simulacije leta.
04:48
we tell the stories through fly-throughs.
105
273000
3000
A ovde, ovo je simulacija leta
04:51
And here, this is a fly-through
106
276000
2000
kroz oblak tačaka Tikala,
04:53
the cloud of points of Tikal,
107
278000
2000
04:55
and here you see it rendered
108
280000
3000
i ovde ga vidite izraženog
i teksturisanog uz pomoć fotografije
04:58
and photo-textured with the photography
109
283000
2000
05:00
that we take of the site.
110
285000
3000
koju uzimamo sa mesta dešavanja.
Ovo nije video.
05:03
And so this is not a video.
111
288000
2000
Ovo su prave 3D tačke
05:05
This is actual 3D points with
112
290000
2000
05:07
two to three millimeter accuracy.
113
292000
3000
sa dva do tri milimetra preciznosti.
05:11
And of course the data can be used
114
296000
2000
I naravno, podaci se mogu koristiti
05:13
to develop 3D models that are
115
298000
3000
da se razviju 3D modeli koji su
05:16
very accurate and very detailed.
116
301000
3000
veoma verodostojni i veoma detaljni.
05:19
And here you're looking at a model
117
304000
2000
Ovde vidite model
05:21
that's extracted from the cloud of points
118
306000
2000
koji je izvađen iz oblaka tačaka
05:23
for Stirling Castle.
119
308000
2000
Zamka Stirling.
05:25
It's used for studies, for visualization,
120
310000
3000
Koristi se za izučavanja, vizualizaciju,
05:28
as well as for education.
121
313000
3000
takođe i u obrazovanju.
05:31
And finally, we produce mobile apps
122
316000
2000
I konačno, proizvodimo mobilne aplikacije
05:33
that include narrated virtual tools.
123
318000
3000
koje uključuju virtualne alatke
koje imaju naratora.
koje imaju naratora.
05:37
The more I got involved
124
322000
3000
Što sam se više uključivao
u oblast očuvanja baštine,
05:40
in the heritage field,
125
325000
2000
sve mi je postajalo jasnije
05:42
the more it became clear to me
126
327000
3000
da mi gubimo lokacije
05:45
that we are losing the sites
127
330000
3000
05:48
and the stories faster than we can
128
333000
3000
i priče brže nego što možemo
05:51
physically preserve them.
129
336000
3000
fizički da ih očuvamo.
Naravno, zemljotresi
05:54
Of course, earthquakes
130
339000
2000
05:56
and all the natural phenomena --
131
341000
2000
i svi prirodni fenomeni -
05:58
floods, tornadoes, etc. --
132
343000
2000
poplave, tornada, itd. -
06:00
take their toll.
133
345000
3000
uzimaju svoj danak.
Ipak, ono što mi se ukazalo je da
06:03
However, what occurred to me was
134
348000
3000
šteta izazvana ljudskim delima,
06:06
human-caused destruction, which was
135
351000
2000
koja ne samo da uzrokuje
06:08
not only causing a significant portion
136
353000
2000
06:10
of the destruction, but actually
137
355000
3000
značajan deo razaranja, već ga u stvari
06:13
it was accelerating.
138
358000
3000
i pojačava.
06:16
This includes arson,
139
361000
2000
Ovo uključuje podmetanje požara,
06:18
urban sprawl,
140
363000
2000
urbana proširenja,
06:20
acid rain, not to mention
141
365000
3000
kisele kiše, da ne pominjemo
terorizam i ratove.
06:23
terrorism and wars.
142
368000
2000
06:25
It was getting more and more apparent
143
370000
3000
Postajalo je sve očiglednije i očiglednije
da bijemo izgubljenu bitku.
06:28
that we're fighting a losing battle.
144
373000
2000
06:30
We're losing our sites
145
375000
2000
Gubimo naše lokacije
06:32
and the stories,
146
377000
2000
i priče,
06:34
and basically we're losing
147
379000
2000
i u suštini gubimo
06:36
a piece -- and a significant piece --
148
381000
2000
deo - značajan deo -
06:38
of our collective memory.
149
383000
3000
našeg zajedničkog pamćenja.
06:41
Imagine us as a human race
150
386000
2000
Zamislite nas kao ljudsku rasu
06:43
not knowing where we came from.
151
388000
4000
koja ne zna odakle je potekla.
06:47
Luckily, in the last two or three decades,
152
392000
3000
Srećom, u zadnje dve ili tri decenije,
06:50
digital technologies have been developing
153
395000
3000
digitalne tehnologije koje su se razvijale
su nam pomogle da razvijemo alatke
06:53
that have helped us to develop tools
154
398000
2000
06:55
that we've brought to bear
155
400000
2000
koje smo počeli da koristimo
06:57
in the digital preservation,
156
402000
2000
pri digitalnom očuvanju -
06:59
in our digital preservation war.
157
404000
2000
u našem ratu za digitalno očuvanje.
07:01
This includes, for example,
158
406000
2000
Ovo uključuje, na primer,
07:03
the 3D laser scanning systems,
159
408000
4000
3D laserski sistem za skeniranje,
07:07
ever more powerful personal computers,
160
412000
3000
sve moćnije personalne kompjutere,
07:10
3D graphics,
161
415000
2000
3D grafike,
07:12
high-definition digital photography,
162
417000
3000
digitalnu fotografije visoke rezolucije,
07:15
not to mention the Internet.
163
420000
3000
da i ne pominjemo Internet.
Usled ubrzanog
07:18
Because of this accelerated
164
423000
2000
tempa uništenja,
07:20
pace of destruction,
165
425000
2000
07:22
it became clear to us that we needed
166
427000
2000
postalo nam je jasno da trebamo
da postavimo sebi
i našim partnerima izazov
i našim partnerima izazov
07:24
to challenge ourselves and our partners
167
429000
3000
07:27
to accelerate our work.
168
432000
2000
koji će ubrzati naš rad.
07:29
And we created a project
169
434000
2000
Pa smo napravili projekat
07:31
we call the CyArk 500 Challenge --
170
436000
3000
koji nazivamo Izazov SajArh 500 -
07:34
and that is to digitally preserve
171
439000
3000
koji se sastoji od digitalnog očuvanja
07:37
500 World Heritage Sites
172
442000
3000
500 svetskih baština
07:40
in five years.
173
445000
2000
u roku od pet godina.
07:42
We do have the technology
174
447000
2000
Imamo tehnologiju
07:44
that's scaleable,
175
449000
2000
koja je podesiva,
07:46
and our network of global partners
176
451000
4000
i naša mreža globalnih partnera
07:50
has been expanding and can be expanded
177
455000
3000
se širila i širiće se
07:53
at a rapid rate,
178
458000
2000
brzim tempom,
tako da smo sigurni
07:55
so we're comfortable
179
460000
2000
da se ovaj zadatak može postići.
07:57
that this task can be accomplished.
180
462000
3000
08:00
However, to me, the 500 is
181
465000
3000
Međutim, za mene, 500
08:03
really just the first 500.
182
468000
4000
je zapravo samo prvih 500.
08:07
In order to sustain our work into the future,
183
472000
4000
Da bismo održali naš rad u budućnosti,
08:11
we use technology centers
184
476000
3000
koristimo tehnološke centre
08:14
where we partner with
185
479000
3000
pri čemu se udružimo
08:17
local universities and colleges
186
482000
2000
sa lokalnim univerzitetima i fakultetima
08:19
to take the technology to them,
187
484000
3000
da njima prenesemo tehnologiju,
pri čemu nam oni mogu pomoći
08:22
whereby they then can help us
188
487000
3000
08:25
with digital preservation of their heritage sites,
189
490000
3000
sa digitalnim očuvanjem njihovih baština,
08:28
and at the same time, it gives them
190
493000
3000
i u isto vreme, to im obezbeđuje
08:31
the technology to benefit from in the future.
191
496000
4000
tehnologiju od koje će imati koristi
u budućnosti.
08:35
Let me close with another short story.
192
500000
4000
Završiću sa još jednom kratkom pričom.
Pre dve godine, pristupio nam je
08:39
Two years ago, we were approached
193
504000
2000
jedan naš partner sa ponudom
da digitalno očuvamo
da digitalno očuvamo
08:41
by a partner of ours to digitally preserve
194
506000
3000
08:44
an important heritage site,
195
509000
2000
jednu važnu baštinu,
baštinu UNESKO-a u Ugandi,
08:46
a UNESCO heritage site in Uganda,
196
511000
3000
08:49
the Royal Kasubi Tombs.
197
514000
3000
grobnice Kasubi.
Posao je uspešno obavljen na terenu,
08:52
The work was done successfully in the field,
198
517000
3000
08:55
and the data was archived
199
520000
2000
i podaci su arhivirani
08:57
and publicly disseminated
200
522000
2000
i predstavljeni publici
08:59
through the CyArk website.
201
524000
3000
kroz vebsajt SajArh.
09:02
Last March,
202
527000
2000
Prošlog marta,
09:04
we received very sad news.
203
529000
3000
primili smo veoma tužne vesti.
09:07
The Royal Tombs had been destroyed
204
532000
3000
Grobnice su uništene
09:10
by suspected arson.
205
535000
3000
i sumnja se na podmetnut požar.
Par dana kasnije, primili smo poziv:
09:13
A few days later, we received a call:
206
538000
3000
„Da li su podaci dostupni,
09:16
"Is the data available
207
541000
3000
i da li mogu biti iskorišćeni
za rekonstrukciju?”
za rekonstrukciju?”
09:19
and can it be used for reconstruction?"
208
544000
4000
Naš odgovor, naravno, bio je „Da.”
09:23
Our answer, of course, was yes.
209
548000
3000
09:28
Let me leave you with a final thought.
210
553000
3000
Da vas ostavim uz ovu poslednju misao:
09:31
Our heritage is much more than
211
556000
3000
Naše nasleđe je mnogo više
09:34
our collective memory --
212
559000
2000
od našeg zajedničkog pamćenja -
09:36
it's our collective treasure.
213
561000
2000
to je naše zajedničko blago.
Dugujemo to našoj deci,
09:38
We owe it to our children,
214
563000
3000
našim unucima i generacijama
09:41
our grandchildren and the generations
215
566000
2000
09:43
we will never meet
216
568000
3000
koje nikada nećemo upoznati
09:46
to keep it safe
217
571000
2000
da ga sačuvamo
09:48
and to pass it along.
218
573000
2000
i prenesemo dalje.
Hvala vam.
09:50
Thank you.
219
575000
2000
(Aplauz)
09:52
(Applause)
220

2000
Hvala vam.
09:56
Thank you.
222
581000
2000
09:58
Thank you.
223
583000
11000
Hvala vam.
10:09
Well, I'm staying here because
224
594000
4000
Dakle,
ostajem ovde jer
10:13
we wanted to demonstrate to you
225
598000
3000
želimo da vam demonstriramo
10:16
the power of this technology
226
601000
3000
moć ove tehnologije
10:19
and so, while I've been speaking,
227
604000
3000
tako da, dok sam ja pričao,
vi ste skenirani.
10:22
you have been scanned.
228
607000
3000
(Smeh)
10:25
(Laughter)
229
610000
3000
10:29
The two wizards that I have
230
614000
3000
Dva čarobnjaka koja imam,
10:32
that are behind the curtain
231
617000
2000
koja su iza zavese,
10:34
will help me bring
232
619000
3000
će mi pomoći da prenesem
10:37
the results on the screen.
233
622000
5000
rezultate na ekran.
(Aplauz)
10:45
(Applause)
234
630000
7000
10:52
This is all in 3D and of course
235
637000
3000
Sve ovo je u 3D-u naravno
10:55
you can fly through the cloud of points.
236
640000
3000
i možete da preletite kroz oblake tačaka.
Možete da ih posmatrate odgore,
10:58
You can look at it from on top,
237
643000
2000
11:00
from the ceiling.
238
645000
2000
sa plafona.
Možete da posmatrate
sa različitih zgodnih tačaka,
sa različitih zgodnih tačaka,
11:02
You can look from different vantage points,
239
647000
2000
ipak, ja ću da tražim od Daga da zumira
11:04
but I'm going to ask Doug to zoom in
240
649000
3000
11:07
on an individual in the crowd,
241
652000
3000
pojedinca u gomili,
samo da pokažemo količinu detalja
11:10
just to show the amount of detail
242
655000
3000
koje možemo da dobijemo.
11:13
that we can create.
243
658000
3000
11:19
So you have been digitally preserved
244
664000
3000
Dakle, digitalno ste očuvani
11:22
in about four minutes.
245
667000
2000
u roku od oko četiri minuta.
11:24
(Laughter)
246
669000
2000
(Smeh)
Želeo bih da zahvalim čarobnjacima ovde.
11:26
I'd like to thank the wizards here.
247
671000
4000
11:30
We were very lucky to have
248

ABOUT THE SPEAKER
Ben Kacyra - Digital preservationistBen Kacyra uses state-of-the-art technology to preserve cultural heritage sites and let us in on their secrets in a way never before possible.
Why you should listen
As a child, Ben Kacyra was taken to visit the ruins of the ancient city of Nineveh near his home town of Mosul in Iraq, giving him an abiding appreciation for the value of history. So when the Taliban destroyed the Buddhas of Bamiyan in Afghanistan in 2001, the Iraqi-born civil engineer was dismayed. In 2002, he founded California-based nonprofit CyArk in order to apply a highly accurate, portable laser-scanning technology he’d originally developed for monitoring nuclear power plants and other structures – to preserving the world’s cultural heritage sites, what Kacyra calls “our collective human memory”.
CyArk’s methods are fast and accurate: pulsed lasers generate 3D points of clouds, which render surfaces at accuracy to within millimeters. Combined with high-definition photography and traditional surveying techniques these data make it possible to create highly detailed media – photo textured animations, 3D fly-throughs – that digitally preserve our knowledge of heritage sites against natural disaster, war, and neglect, and make them accessible to the world. Among the sites already scanned are ancient sites in Mexico, the leaning tower of Pisa, and Mount Rushmore.
