3-D Technology Offers Clues to How Egypt’s Pyramids Were Built | Nat Geo Live

my archeological team actually is very

unique because I'm the only ecologist

and the other members are computer

scientists software engineers and

applied mathematicians we are like a

crime scene investigation with patiently

document with latest technology the

construction technique of a planet today

I'm going to talk about one of the most

exciting experience in my academic life

that is climbing the great planet I've

been fascinated by planet Egypt since

the time of energy a high school but the

reason why I climb the pyramid is not

just in a fascination the purpose of the

climbing of the planet for ecologist is

to obtain data so the traditional

approach to the study of racial Egypt is

like you know jigsaw puzzle we ecologist

collects the data from the excavation

site and then start to describe the past

but as a consequence actual survey data

is less frequently updated this is a

particularly tool for the planet at Giza

and also such traditional documentation

is done by line drawing which does not

be pleasant actual state of the monument

such a critical documentation only focus

on external part of the planet and in a

space such as chamber and you know the

space and corridor so no observation of

the core of the planet has been made

supplies ngey there is a three kind of

in all hypotheses probably in the curve

the pyramid may consist of horizontal

valence blocked or some ejector just be

deep maybe has a step planet or the core

may build by what we called an

acceleration layer but we don't know

which is true the input

of the study of the cost lecture will be

related to the construction technique

namely the type of the lump ancient

Egyptian employed for example if ramp is

straight maybe this is suitable for

setting arrange the block or if a planet

has a cost step probably in a zig zag

lump will be you know the EGD set on the

cost up or implement has a layer we

called on a spinal amber up clamp would

be appropriate for that but we don't

know which is quite but luckily there is

a place we can actually observe the cost

lecture of the pyramid but which is

located 80 meter from the ground so you

have to actually climb up the pyramid it

was a you know the quite experience for

me because this is the ancient monument

you have to climb without PTIN and the

safety log after two and a half hours so

we did in this area this is how open

space called knotch and interestingly

this not has a kind of you know crevice

in the West so that led to another small

open space called cave so we really

wanted to document this area however we

could not actually bring any stabbing

equipment such as you know laser scanner

because there's ask Allah is heavy and

big but we had to somewhat a make

archaeological documentation with the

video footage my archaeological team

actually is very unique because I am the

only ecologist and the other members are

computer scientists software engineers

and applied mathematicians and computer

scientists came up with idea to employ

structure from motion technique so this

technique allows you to stitch image

from the video footage for the

reconstruction of our study area

20 minutes video footage what splatting

to 300,000 image rain and this is our

result so this is a first decoding of

the these areas so let's compare our

data with previous surveys so whether

this is horizontally orange block or

stepped color or layer so this is a also

photographic section a produced from our

3d data as you can see here it showed

totally different structure and you may

wonder what this you know the Cape like

so I presume this is a place ancient

Egyptian used for packing in feeling of

sand and also devvra's this is actually

well known technique in ancient Egypt

called chamber methods so which apply to

you know the construction of the temples

and the cities and also the pyramid in

in a delayed period Middle Kingdom

pyramids but this technique accumulates

a walk in d'marco bleah economical way

but we didn't know this technique

actually applied in all the kingdom

planets probably this is a first one so

finally where is the top of the Great

Pyramid after the cramming of fibroids

so again we used the video footage and

digital image for structure from motion

process and multi booster system and

this is a the first detailed plan of the

top of the planet which can tell us lot

of information but by their nature this

image cannot be Pleasant 3d information

so again our computer scientist came up

the idea new display method of 3d called

picot so this is a carelessness map and

warmer color means shorter distance from

viewer and the cooler color means longer

distance and the peak it I also can

indicate rich

and the valley which is also very

important for our clerical analysis and

finally this is our 3d data we are like

you know the crime scene investigation

we patiently document with latest

technology and then began to demonstrate

as a construction technique of a

particular area such as top of the

planet and area on the north end okay

and I hope I can continue to collect the

data of important areas around the

Pyramid of Giza so eventually the

reality of the pyramid will be deleted

which also tell us the arity of the

civilization thank
