According to the Dunhuang mural protection plan, no wiring rack lamps are allowed in any cave.

When I first entered from the outside, my eyes were very uncomfortable, I couldn't see anything, I just felt that the temperature of the air around me was cold and hot, just like a curtain hung in summer to prevent heatstroke, some places were lifted, and some places blocked the heat wave outside.

"Ouyang, you're here!" A young man's voice, with a spectrum of pork belly, feels like a fat man.

"Well, it's me." Ouyang replied politely.

"Who else is it?"

MAY'S EYES WERE GRADUALLY ADJUSTING TO THE NEW ENVIRONMENT, AND HE COULD VAGUELY SEE A BLACK SQUARE SHELL WITH SEVERAL SLENDER ARMS AND LEGS, ALL OF WHICH WERE CROOKED, SWAYING FROM SIDE TO SIDE.

"What is this, Robot Story? Was it artificial intelligence who was talking to me just now? ”

Then, a small fluffy curly hair emerged from behind the square shell, followed by a pair of thick-rimmed black-rimmed round glasses, and finally the whole head was exposed.

"Hah, a little raccoon!" MAY BURST OUT LAUGHING.

"Yo, this is flying to the earth?" The fat man spoke.

"Are you saying I'm fat?"

"I mean, you're light and elegant, and your temperament is elegant and generous!"

"You two know each other?" Ouyang interrupted them,

"I don't know!"

"I don't know!"

The two said in unison.

"Then why pinch as soon as we meet?" Ouyang didn't understand,

"Who told her to say that I was a little raccoon, have you ever seen such a slender little raccoon?" The fat man blurted out.

"Huh? Hahaha, I'm talking to myself, since you heard it, then I'll give you this title, no thanks! "MAY SAID THAT HE IS VERY GENEROUS AND DOES NOT HAVE THE SAME KNOWLEDGE AS MEN.

"You ......"

"Your way of greeting can be selected as one of the top 10 Internet buzzwords of the year.

LET ME INTRODUCE YOU, THIS BEAUTIFUL WOMAN NEXT TO ME IS CALLED MAY LI, A CHEMISTRY EXPERT FROM ABROAD. ”

"Oh, I can't see it, it's still chemistry ~ learning ~ specialization ~ home ~" The fat man deliberately lengthened his tone.

"Little Raccoon is my colleague and my good buddy, and he is an all-rounder in computer and digital here, mainly responsible for shooting, preserving, and sorting out the information of the existing murals, and using image processing technology to restore the original state of the murals to the greatest extent, and will also use AR technology to output them later to increase the observability and interactivity.

"Yes, little raccoon!" MAY MEDITATED IN HIS HEART.

He also has an identity, a writer, who uses his spare time to promote Dunhuang culture.

His full name is Liu Sasa, we all call him Da Liu, the one next to him is Bi Li, and this one here is Qin Tian......"

I DON'T REMEMBER THE NAME AT THE BACK, AND THE WORD BIG LIU WAS TURNING OVER AND OVER IN HER HEAD.

"Ouyang Jinglin,

LIU Sasa,

They all call me Ouyang,

We all call him Da Liu,

Ouyang and Da Liu,

They are colleagues......"

"Am I really awake?"

"MAY, WHAT'S WRONG WITH YOU?" Ouyang interrupted MAY's thoughts.

"Oh, it's okay, it's okay, I was a little dizzy just now, and I'm fine."

"Just scratched your brain from the claws of a little raccoon." Da Liu made a scaring gesture.

"What kind of brain circuit are you, people who work on computers have negative emotional intelligence." MAY gave Da Liu a roll of his eyes.

"How do you say that?

The night gives you black eyes and lets it lead you to the light. You're good, but you're using it to roll your eyes! ”

Everyone was amused by Da Liu's words, and MAY is not a person who can't afford to joke, so he doesn't care anymore.

MAY'S EYES HAVE SURVIVED A BRIEF PERIOD OF DARKNESS AND CAN NOW SEE THINGS AROUND THEM.

There are 6 people in the cave plus her, and the black square shell is a camera, and Da Liu is manipulating the camera to shoot in the cave.

The digitization of the cave murals is to rescue the precious cultural relics of the Dunhuang grottoes, so that they can be permanently and authentically preserved; At the same time, it provides accurate and detailed information for the study of Dunhuang studies, and can make virtual caves for tourists to enjoy and visit, so as to relieve the pressure of opening the grottoes and protect the murals.

The technical principle of the digitization of Dunhuang murals is to use high-precision digital cameras to shoot large-format murals in frames, and then use computer technology to stitch and restore, so as to achieve the purpose of high-precision digitization of large-format murals.

In the protection of the cave murals, the digital technology of the murals was introduced to be applied to the investigation of the disease status in the preliminary work, the digital mural images were used to replace the traditional silver salt film records, and the computer was used to generate the line drawing base map, and then the disease distribution map of the mural was depicted based on the line drawing base map, which greatly improved the efficiency of the protection work.

Combined with the existing research on mural pigments and the physical and chemical mechanism of change, the process expression of mural color change is represented by computer visual technology, which has become an important auxiliary tool for the study of mural color change reduction.

In grotto archaeology, the achievements of digital technology of murals provide high-quality digital mural images for archaeological work, and research and development of new digital technology means and information integration methods. In the future, even if you can't visit the site, you can use digital image processing technology to achieve the effect of virtual reality, as if you are there; If we are at the scene, we can use augmented reality technology to let people from thousands of years ago come out and talk to us, so that we can understand their situation and state of mind at that time.

MAY was a little excited, but I didn't expect that the digital development of the motherland has reached the forefront of the world, rejuvenating the country with science and technology, rejuvenating the country with hard work, and the young people in the new era are so good. It is said that heroes have been teenagers since ancient times, but today's teenagers are more heroic!

"If I can also do something for the protection and development of art in my motherland, it will probably be the greatest thing I have done in my life, in case it can go down in history!" MAY spins his brain.

"Let's take a look when you come in, this cave hasn't been opened to the public yet, you're lucky." Ouyang said.

"Thanks to you today, thank you.

You're a colleague of Little Raccoon, and you're also working on digital images? MAY ASKED.

"I'm not.

I am engaged in Dunhuang art research, popularly speaking, is to understand the past history, culture, art, life, military, agriculture, etc. through the content and expression of the murals, because I have been painting since childhood, so I am responsible for part of the protection and restoration work.

We encountered difficulties in the protection and restoration of the color of the murals, so we invited an expert group to study and discuss together. Ouyang replied.

"In ancient times, the pigments were all natural ores ground into powder and mixed with water, and the expressiveness of the colors was completely different from that of today's chemical pigments. In other words, if no new pigment varieties can appear, the existing varieties, no matter how they are blended, cannot be 100% restored, is this what it means? MAY LOOKED AT OUYANG AND SAID.

"Yes, we have tried all kinds of combinations of existing pigments, and they can't be mixed with water, oil, pine resin, etc. If new pigments could not be invented, the restoration would have to be pushed back many years. So, we need experts in chemistry to solve the problem for us. ”

"Chemistry expert? Isn't that me! Just now, I was thinking about how to make some contribution to the development of art in my motherland, and this opportunity has come! MAY secretly rejoiced.

"Well, I still do a lot of chemistry experiments, and I'm the top technical talent in our school, besides, I can't have a better mentor, why don't I try it?"

Ouyang smiled, as if this was the answer he had been waiting for for a long time.

"We have limited funds, I'm afraid we can't afford to hire a big expert like you." Ouyang said this deliberately.

"The laboratory has it, the equipment has it, the materials have it, and that's enough. After success, remember to write my name in the materials you submitted, and I will go down in history! Money, it's easy to say, it's easy to say, hehe! ”

"Okay, welcome to the Huangyan Group!"

"What, the lie group?"
