TED Talks, Ben Kacyra: Ancient wonders captured in 3D

Ben Kacyra: Ancient wonders captured in 3D

I'd like to start with a short story.It's about a little boy whose father was a history buff and who used to take him by the hand to visit the ruins of an ancient metropolis on the outskirts of their camp.They would always stop by to visit these huge winged bulls that used to guard the gates of that ancient metropolis,and the boy used to be scared of these winged bulls,but at the same time they excited him.And the dad used to use those bulls to tell the boy stories about that civilization and their work.

Let's fast-forward to the San Francisco Bay Area many decades later,where I started a technology company that brought the world its first 3D laser scanning system.Let me show you how it works.Female Voice: Long range laser scanning by sending out a pulse that's a laser beam of light.The system measures the beam's time of flight,recording the time it takes for the light to hit a surface and make its return.With two mirrors, the scanner calculates the beam's horizontal and vertical angles, giving accurate x, y, and z coordinates.The point is then recorded in to a 3D visualization program.

All of this happens in seconds.Ben Kacyra: You can see here, these systems are extremely fast.They collect millions of points at a time with very high accuracy and very high resolution. A survey or with traditional survey tools would be hard-pressed to produce maybe 500 points in a whole day.These babies would be producing something like ten thousand points a second. So, as you can imagine, this was a paradigm shift in the survey and construction as well as in reality capture industry. Approximately ten years ago,my wife and I started a foundation to do good,and right about that time,the magnificent Bamiyan Buddhas,hundred and eighty foot tall in Afghanistan,were blown up by the Taliban.They were gone in an instant.And unfortunately, there was no detailed documentation of these Buddhas.This clearly devastated me,and I couldn't help but wonder about the fate of my old friends, the winged bulls,and the fate of the many, many heritage sites all over the world.

Both my wife and I were so touched by this that we decided to expand the mission of our foundation to include digital heritage preservation of world sites.We called the project CyArk, which stands for Cyber Archive. To date, with the help of a global network of partners, we've completed close to fifty projects.Let me show you some of them: Chichen Itza,Rapa Nui --and what you're seeing here are the cloud of points --Babylon, Rosslyn Chapel,Pompeii,and our latest project, Mt.

Rushmore,which happened to be one of our most challenging projects.As you see here, we had to develop a special rig to bring the scanner up close and personal.The results of our work in the field are used to produce media and deliverables to be used by conservators and researchers.We also produce media for dissemination to the public --free through the CyArk website.These would be used for education,cultural tourism, etc. What you're looking at in here is a 3D viewer that we developed that would allow the display and manipulation of [the] cloud of points in real time, cutting sections through them and extracting dimensions.This happens to be the cloud of points for Tikal.

In here you see a traditional 2D architectural engineering drawing that's used for preservation, and of course we tell the stories through fly-throughs.And here, this is a fly-through the cloud of points of Tikal,and here you see it rendered and photo-textured with the photography that we take of the site. And so this is not a video.This is actual 3D points with two to three millimeter accuracy. And of course the data can be used to develop 3D models that are very accurate and very detailed. And here you're looking at a model that's extracted from the cloud of points for Stirling Castle.It's used for studies, for visualization,as well as for education. And finally, we produce mobile apps that include narrated virtual tools.The more I got involved in the heritage field,the more it became clear to me that we are losing the sites and the stories faster than we can physically preserve them.

Of course, earthquakes and all the natural phenomena --floods, tornadoes, etc. --take their toll.However, what occurred to me was human-caused destruction, which was not only causing a significant portion of the destruction, but actually it was accelerating.This includes arson,urban sprawl,acid rain, not to mention terrorism and wars.It was getting more and more apparent that we're fighting a losing battle.We're losing our sites and the stories,and basically we're losing a piece -- and a significant piece --of our collective memory. Imagine us as a human race not knowing where we came from. Luckily, in the last two or three decades,digital technologies have been developing that have helped us to develop tools that we've brought to bear in the digital preservation,in our digital preservation war.This includes, for example,the 3D laser scanning systems,ever more powerful personal computers,3D graphics,high-definition digital photography,not to mention the Internet.Because of this accelerated pace of destruction,it became clear to us that we needed to challenge ourselves and our partners to accelerate our work.And we created a project we call the CyArk 500 Challenge --and that is to digitally preserve 500 World Heritage Sites in five years.

We do have the technology that's scaleable,and our network of global partners has been expanding and can be expanded at a rapid rate,so we're comfortable that this task can be accomplished.However, to me, the 500 is really just the first 500.In order to sustain our work into the future,we use technology centers where we partner with local universities and colleges to take the technology to them,where by they then can help us with digital preservation of their heritage sites,and at the same time, it gives them the technology to benefit from in the future.

Let me close with another short story.Two years ago, we were approached by a partner of ours to digitally preserve an important heritage site,a UNESCO heritage site in Uganda,the Royal Kasubi Tombs.The work was done successfully in the field,and the data was archived and publicly disseminated through the CyArk website.Last March,we received very sad news.The Royal Tombs had been destroyed by suspected arson.A few days later, we received a call: "Is the data available and can it be used for reconstruction?

Our answer, of course, was yes. Let me leave you with a final thought.Our heritage is much more than our collective memory --it's our collective treasure.

We owe it to our children,our grandchildren and the generations we will never meet to keep it safe and to pass it along.Thank you. (Applause)Thank you.

Thank you.

Thank you.

Well, I'm staying here because we wanted to demonstrate to you the power of this technology and so, while I've been speaking,you have been scanned.

(Laughter)The two wizards that I have that are behind the curtain will help me bring the results on the screen. (Applause)

This is all in 3D and of course you can fly through the cloud of points.You can look at it from on top, from the ceiling.You can look from different vantage points, but I'm going to ask Doug to zoom in on an individual in the crowd,just to show the amount of detail that we can create.So you have been digitally preserved in about four minutes.

(Laughter) I'd like to thank the wizards here.We were very lucky to have two of our partners participate in this:the Historic Scotland,and the Glasgow School of Art.I'd like to also thank personally the efforts of David Mitchell,who is the Director of Conservation at Historic Scotland.

David. (Applause) And Doug Pritchard, who's the Head of Visualization at the Glasgow School of Art.Let's give them a hand. (Applause)

Thank you.

I’d like to start with a short story.It’s about a little boy whose father was a history buff and who used to take him by the hand to visit the ruins of an ancient metropolis on the outskirts of their camp.They would always stop by to visit these huge winged bulls that used to guard the gates of that ancient metropolis,and the boy used to be scared of these winged bulls,but at the same time they excited him.And the dad used to use those bulls to tell the boy stories about that civilization and their work. ||||||||||||||||||||||||||||||||||||||periphery|||||||||||||winged bulls||||||||||||||||||||||||||||||||||||||||||||||||| Eu gostaria de começar com uma história curta: é sobre um garotinho cujo pai era apaixonado por história e que costumava levá-lo pela mão para visitar as ruínas de uma metrópole antiga nos arredores de seu acampamento. para visitar esses enormes touros alados que costumavam guardar os portões daquela metrópole antiga, e o garoto costumava ter medo desses touros alados, mas ao mesmo tempo eles o excitavam. E o pai costumava usá-los para contar aos histórias de meninos sobre essa civilização e seu trabalho.

O sistema mede o tempo de vôo do feixe, registrando o tempo necessário para que a luz atinja uma superfície e faça seu retorno.Com dois espelhos, o scanner calcula os ângulos horizontal e vertical do feixe, fornecendo precisão coordenadas x, ye z. O ponto é então gravado em um programa de visualização 3D.

Eles desapareceram em um instante. Infelizmente, não havia documentação detalhada desses Budas. Isso claramente me devastou, e eu não pude deixar de me perguntar sobre o destino de meus velhos amigos, os touros alados e o destino de muitos e muitos patrimônios em todo o mundo .

And finally, we produce mobile apps that include narrated virtual tools.The more I got involved in the heritage field,the more it became clear to me that we are losing the sites and the stories faster than we can physically preserve them. E, finalmente, produzimos aplicativos móveis que incluem ferramentas virtuais narradas. Quanto mais eu me envolvia no campo da herança, mais ficou claro para mim que estamos perdendo os sites e as histórias mais rapidamente do que podemos preservá-los fisicamente.

Of course, earthquakes and all the natural phenomena --floods, tornadoes, etc. --take their toll.However, what occurred to me was human-caused destruction, which was not only causing a significant portion of the destruction, but actually it was accelerating.This includes arson,urban sprawl,acid rain, not to mention terrorism and wars.It was getting more and more apparent that we’re fighting a losing battle.We’re losing our sites and the stories,and basically we’re losing a piece -- and a significant piece --of our collective memory. No entanto, o que me ocorreu foi a destruição causada por humanos, que não estava apenas causando uma parte significativa da destruição, mas também estava se acelerando. Isso inclui incêndio criminoso, expansão urbana, chuva ácida, sem mencionar o terrorismo Estava ficando cada vez mais evidente que estamos travando uma batalha perdida. Estamos perdendo nossos sites e histórias, e basicamente estamos perdendo uma parte - e uma parte significativa - de nossa memória coletiva. Imagine us as a human race not knowing where we came from. Imagine-nos como uma raça humana sem saber de onde viemos.

Deixe-me encerrar com outra história curta. Dois anos atrás, fomos abordados por um parceiro nosso para preservar digitalmente um importante patrimônio, um patrimônio da UNESCO em Uganda, os Túmulos Reais Kasubi. O trabalho foi realizado com sucesso em campo e os dados foram arquivados e divulgados publicamente no site da CyArk. Em março passado, recebemos notícias muito tristes. Os túmulos reais foram destruídos por suspeita de incêndio criminoso. Alguns dias depois, recebemos uma ligação: "Os dados estão disponíveis e podem ser usado para reconstrução?

Our answer, of course, was yes. Nossa resposta, é claro, foi sim. Let me leave you with a final thought.Our heritage is much more than our collective memory --it’s our collective treasure. Deixe-me deixá-lo com uma reflexão final. Nossa herança é muito mais que nossa memória coletiva - é nosso tesouro coletivo.

We owe it to our children,our grandchildren and the generations we will never meet to keep it safe and to pass it along.Thank you. Devemos isso aos nossos filhos, netos e às gerações que nunca encontraremos para mantê-lo seguro e transmiti-lo. Obrigado. (Applause)Thank you.

Thank you.

Isso é tudo em 3D e, é claro, você pode voar através da nuvem de pontos. Você pode vê-lo de cima, do teto. Você pode olhar de diferentes pontos de vista, mas vou pedir a Doug para ampliar um indivíduo na multidão, apenas para mostrar a quantidade de detalhes que podemos criar. Assim, você é preservado digitalmente em cerca de quatro minutos.

(Laughter) I’d like to thank the wizards here.We were very lucky to have two of our partners participate in this:the Historic Scotland,and the Glasgow School of Art.I’d like to also thank personally the efforts of David Mitchell,who is the Director of Conservation at Historic Scotland. Eu gostaria de agradecer aos assistentes aqui. Tivemos muita sorte de ter dois de nossos parceiros participando disso: a Escócia Histórica e a Escola de Arte de Glasgow. Gostaria de também agradecer pessoalmente os esforços de David Mitchell, que é o diretor de conservação da Historic Scotland.
