I don't want to solve the case when I'm a little policeman.

Although Xu Zheng promised Jian Xueqing that he would focus on the escape case in Zhenhai City.

But his focus was not on that.

Because the Chinese New Year is approaching, all departments are busy, especially Zheng Heming's studio, which already has a lot of work and has to cooperate with the [-]-day anti-trafficking operation deployed by the ministries and commissions.

The leader said that the Hundred Days Anti-Human Trafficking Operation must have results, and the results must not be lower than before.

But the real situation is that Zheng Heming's studio has helped anti-trafficking offices in various places recover thousands of abducted children this year.

Now the leaders of the ministries and commissions are asking local anti-trafficking offices to set new highs. How is this possible?
But the leaders' orders have been issued, and the people below have to pretend to work day and night even if they can't complete them. In addition, various provinces and cities have to compete in the arena.

Therefore, a large amount of help information was sent to Zheng Heming.

Even Xu Zheng himself, most of his social circle is in Pingjiang Province, and many people from anti-trafficking offices in other provinces have come to him for help.

Even Professor Xie and the others couldn't sit still. They urged Xu Zheng to work overtime all day long, as if they wanted to take advantage of this [-]-day anti-trafficking operation to launch a big one.

But Xu Zheng is not optimistic, because Zheng Heming's research project has not been successfully studied, and the success rate of simulation portraits is still not high. Even if he works overtime, he can only get back a few more children.

Ever since he came back from the Magic City, he had always had an idea in his mind. No, he retreated for two days and wrote a research outline.

At 1.22 o'clock in the evening on January [-], in his name, he invited a deputy director of the Provincial Anti-Human Trafficking Office and Director Ye Tao, Zheng Heming, the simulation portraitist who is now staying in Changming, and the subordinates of the Provincial Science and Technology Information Corps. A senior engineer in the big data analysis department.

In addition to Wan Haihong and Zhang Yuqi who came with friendly support, and his current bosses, Peng Wanyou and Jian Xueqing.

Xu Zheng first asked Wen Jie to distribute the outline he compiled to everyone present, "Thank you all leaders and seniors for coming here despite your busy schedule."

Just as Xu Zheng was bowing his head and standing in front of the conference table to express his gratitude to everyone, Peng Wanyou, the most senior official, looked at the outline and waved his hand, "You kid, don't do the ink. I won't tell you how much you are taking up our off-duty time. Can you just tell me?" Going to the topic?

We don't want your sweet words. "

Wan Haihong is now also the deputy director of the municipal bureau. He is a high-ranking deputy in a sub-provincial city and is already at the deputy department level. "Haha, Director Peng is right. There are so many of us who don't have time to listen to your talk. Just tell us what we are here to do." That’s fine.”

The same goes for Professor Xie's quick temper, "Xiao Xu, if you let us come this time, you have to make up for our time. At least you have to come to the studio and work overtime for two nights."

The people Xu Zheng invited were basically acquaintances, and even if they were not familiar with each other, they had worked together before. Seeing that everyone was becoming curious, he said bluntly: "That's it, I went to the Magic City on a business trip some time ago.

It was found that they were at the Hongqiao High-speed Railway Station, using instruments to scan every person exiting the station, and then the computer collected the scanned person's skull, generated a 3D skull model, and then matched it with the suspect's skull in the database.

This is what I think. Although the existing Skynet project can track and monitor every passerby 24 hours a day, including his daily movement trajectory and Internet browsing records, etc.

But if every city's safe city project has skull collection functions and 3D modeling, then big data can automatically match missing people and abducted people.

Do you think this can lead to a world without abductions? "

Many people talk about universal DNA collection. Let’s not talk about how much manpower and material resources universal collection requires. The biggest problem is security, in case the DNA data of the entire population is leaked.

Or if it is obtained by bad people, the consequences will be disastrous.

After all, genetic medicine and genetic warfare are no longer theoretical things.

Therefore, the plan proposed by Xu Zheng is to build a national skull model, which is similar to a fingerprint database and a face database. However, children's fingerprints are not finalized before the age of three, so it is of little significance to compare national fingerprints to find abducted children.

Zheng Heming understood, but he still had questions, "Generally, the skull of a child born by natural birth or caesarean section will begin to take shape at six months, with 1-3 being considered the basic shape, and the complete shape will not be until the child is 18 years old.

Then your method will not be effective for babies under six months old.

The skull of a child between six months and three years old will also change due to factors such as disease, sleeping position, water and soil.

In other words, skull scanning 3D modeling is suitable for children after the age of three. "

Professor Xie held a different opinion, "Actually, the baby's shape is initially finalized at 6 months old. Although there will be factors that affect the skull in the future, Lao Zheng, have you ever thought about it? The research we are doing now is not based on the changes in the child's face. Does it change due to factors?
I think Xiao Xu can study this method. "

Deputy Director Liu of the provincial anti-trafficking department also expressed his opinion, “Actually, most of the abducted children are 1-3 years old, and there are also some under one year old, but not many. The main reason is that it is difficult to feed them.

So if you can determine the skull changes of children aged 1-3 years old, Xiao Xu’s method still has great potential. "

Ye Tao also thinks it is feasible, "As long as it is helpful to our anti-trafficking operation, I think it will be fine."

Si Jinshan, a senior engineer from the Big Data Analysis Department, has a different opinion, "Xiao Xu's method is technically not difficult. The current Sky Eye system itself can collect the appearance and body shape of people under the camera.

Next, we can generate a 3D skull model of the person under the person's avatar collected by the system, and automatically match it when the program runs autonomously.

However, our domestic skull database currently only collects skull data of 10 people.

There is too little data to make comparisons.

This is on the one hand, and on the other hand is the computer for 3D scanning and data storage, as well as the maintenance and operation of related personnel, which requires a large amount of funds and personnel.

It is estimated that in the end, the leader of the ministry or a higher level leader will have the authority to decide on this matter. "

Xu Zheng felt that the first difficulty he mentioned was not a difficulty, "Teacher Si, now our domestic ID cards are basically available to all citizens over 18 years old.

We can let the computer automatically generate 3D skull models of people across the country through the photos on their student status and ID cards, so as to establish a database.

As for how much money and manpower it will cost to run this skull database, I think it should be left to the leadership above to decide. Let’s just say whether this thing can be done? "

This time Si Jinshan nodded, he pushed up his glasses, "The domestic student status is relatively well established from kindergarten to university, but there is one thing. If someone does not go to kindergarten or school, then the database can only wait until he is 18 years old. Registered 3D skull."

Wan Haihong pondered for a long time, "If 3D skull modeling can really identify abducted children and missing persons, then in criminal investigation cases, such as suspects having plastic surgery, disfigurement or wearing 3D hoods.

Can they be identified? "

"Theoretically, it can be identified, unless it's the kind of plastic surgery person who even replaces the entire head." Xu Zheng did not go into details about the Hongqiao High-speed Railway in Shanghai due to discipline, but he saw the 3D head modeling with his own eyes.

Peng Wanyou tapped his fingers on the table and smiled, "Xiao Xu, tell me what you really think quickly. What kind of skull 3D database? Can this be something that a few of us and several departments can decide?

If you are so smart, don't you understand that even if a 3D skull database is established, that is something that the leaders of the ministry need to consider.

If you want to report to the higher authorities and be the first proposer of the skull database, we will naturally support you, but I don’t think you will consider something that will take a year, two years, or even three or four years to complete. "

"Hehe, Director Peng is indeed getting smarter as he gets older." After getting along for a long time, Xu Zheng also got along very well with his current leader, "That's it, I think we can try it out now.

"Wen Jie, make another pot of good tea for all the leaders."

Seeing that the big guy was quietly waiting for the next step, he had to come up with his real thoughts this time, "As for the 3D skull database, I want to send an email to the leader of the Ministry of Public Security.

But I just sent an email and made a suggestion.I invite you to come because I want to take advantage of the Spring Festival holiday to use the Sky Eye system to scan people entering and leaving at checkpoints at the city's highways, train stations, airports and major tourist attractions, and generate 3D skull models of them.

Create a small database.

Then we generate 3D skull models from the photos of the A/B wanted criminals, Hongtong and other fugitives on the Internet that we want to arrest.

Comparing the two items, do you think you can find the wanted criminals hiding in Changming City? "

Zheng Heming is now devoted to the cause of anti-trafficking. After hearing this, he directly added: "There are also abducted children and women. For children, the skull of a child when he is about three years old can be X1.6, which is his skull as an adult."

Deputy Director Liu of the Anti-Human Trafficking Office shook his head, "It is directly multiplied by 1.6 times, without considering the growth of children, so the adult skulls generated by big data will definitely miss many abducted children."

Xu Zheng also understood this. His method was not to retrieve the abducted children. It was mainly to capture the fugitives. Taking advantage of the crowds during the Spring Festival, these fugitives hiding in various corners of Changming should take the opportunity to come out and walk around. .

"Teacher Si, if you add a program to automatically generate a 3D skull model in the Skynet system, how long will it take to complete it?
How much is it? "

Si Jinshan is a professional in this field. Hearing this, he smiled bitterly and said: "It doesn't cost a lot, but we don't have this 3D skull modeling program in Pingjiang, so we have to apply to our superiors.

In addition to this, the most important thing is that [-]% of the resources of the Ever Bright Eyes system are to cooperate with the Spring Festival transportation.

You must have the ability to get the leaders in the department to agree. I think the leaders of our Science and Technology Information Corps have no objections. "

Xu Zheng immediately looked at Peng Wanyou. In addition to the usual functions, the city's Sky Eye system also added a camera to generate a 3D skull model, and then automatically matched the fugitive's data.

This series of operations is not all a task to save the pursuit and escape office.

Who told you that the Fugitive Pursuit Office is responsible for arresting fugitives across the province?

Peng Wanyou didn't expect that in the end, he would have to apply for permission from his superiors himself. He looked at Jian Xueqing and said, "Xiao Xu, have you discussed this matter in advance?

Co-author You invited so many people today just to let me come forward. "

When Jian Xueqing saw that Peng Ting was not angry, he smiled and shook his head, "I won't hide it from you, Xu Zheng did talk to me, and he devised several strategies to get you to agree.

In fact, his real plan was to take a holiday on May Day.

All departments are busy during the Spring Festival, and the leaders will definitely not agree to allocate another share of the Tianyan system's resources.

Moreover, the Chinese New Year is only half a month away, and there is no time to make arrangements. "

Peng Wanyou pretended to "hum" at Xu Zheng, and Wan Haihong and other leaders also laughed. In fact, everyone thought his proposal could be implemented. They were just thinking about it if the leaders agreed to try it during the Spring Festival. .

What benefits could these units get from it, but they never thought about Xu Zheng's real purpose.

On May [-]st Labor Day, Changming’s traffic volume was not much worse than that during the Spring Festival. At least the number of visitors received would not be less than [-] million. This is such a huge flow of people.

If you use the Sky Eye system plus a 3D skull model to search for fugitives, you will definitely not be looking for a needle in a haystack, but [-]% hope to find a few big fish.

Professor Xie had a bad temper and drank the tea in his hand without even tasting it. Then he stood up and said, "This 3D skull model is indeed very useful in chasing escapees. After all, today's fugitives either have plastic surgery or use various disguises." .

But there is still much to be done to help abducted children.

Xiao Xu, I think we can combine the 3D skull model with face recognition. When the face database and skull database are completed, it will be much easier for us to find the abducted children.

You can even achieve a world without crutches!

When you finish writing the proposal to the ministry, I will be the first to sign and support you. "

After finishing speaking, the old man hugged everyone and apologized: "I'm sorry, everyone. We still have many tasks to complete in our studio, and we have to work overtime. Let's take a step first."

Zheng Heming and other professors also stood up, expressed their support for Xu Zheng, and then left together.

Then others saw this and said goodbye one after another. Xu Zheng stood directly at the door of the conference room to see off the guests one by one, and said that he would take time to treat the guests to dinner. In the end, only Wan Haihong, Zhang Yuqi, Peng Wanyou and Jian Xueqing remained. Got here.

Wen Jie had been doing odd jobs, serving tea and water, taking meeting minutes, and not expressing his own opinions. Xu Zheng saw that it was already 08:30 in the evening, so he asked her to go home first.

The five of them sat down, and Zhang Yuqi joked with a sour tone: "Xu Zheng, you are becoming more and more capable now. With just one idea of ​​your own, you can ask the leaders of so many departments to come over and give you advice."

The four people present here are all led by themselves. Xu Zheng felt that this was one of his own, so he spoke casually, "Captain, what are you saying? Just now you were Xu Shu who entered Cao's camp without saying a word!"

"That's because you are not sincere. Since you are asking for something, shouldn't you open a private room in the hotel and let us all eat and talk?"

Xu Zheng shook his head, "If I ask everyone to go to the hotel, Professor Xie and his gang will just shake their heads and refuse to agree."

Peng Wanyou yawned, "Okay, let's get down to business. I think Xiao Xu's idea is good, and it's just right for May Day.

As for the suggestion to the ministries and commissions to establish a skull database, I think you should talk to Gu Ting first. Some things should not only consider whether it is good for the people, but also whether it will be beneficial to the leaders.

Otherwise, your suggestions will not be ignored by the superiors.

Even if the higher-ups agree, it will take two or three years before it is actually implemented. It is estimated that by then you will no longer be pursuing fugitives. "

Xu Zheng realized that there was something in Peng Ting's words, but he didn't say it, and he couldn't ask. Just as he was thinking about it, Wan Haihong said: "Building a skull model is not only helpful for criminal investigation and anti-trafficking.

Just like face database and fingerprint database.

Compared with DNA databases, skull databases are relatively safe and cheap, and skulls can be generated directly from face databases. If leaders agree, it should not take two or three years.

But as Lao Peng said, this matter cannot be decided by one leader. Coupled with the mutual wrangling and buck-passing, it may take two or three years. "

In two or three years, Xu Zheng probably no longer works in the fugitive pursuit system, but as long as the face database and skull database are improved, [-]% of the fugitives still in the country will be caught.

He can be sure of that.

After all, there are not many fugitives who are willing to hide in ravines and live in seclusion in the mountains.

He has been busy for several days, and today he has found so many people. What he really wants to do has not yet been settled, so he takes the initiative to ask: "Dear leaders, do you think the ancient hall will agree to hold May Day in various places with a large number of people in the city?" Scan people’s skulls?”

Peng Wanyou and Wan Haihong just looked at each other and smiled without saying a word. Jian Xueqing also became happy. Only Zhang Yuqi looked disgusted and said, "You kid, we are not enlightened. Is this the place to talk about things?"

Only then did Xu Zheng realize that he was a fan of the authorities. Whether Gu Ting agreed or not, he had to rely on Peng Ting and Wan detachment to act as lobbyists, just like he did today with one small strategy after another against Peng Ting.

"Hehe. It's my fault. How can I make the leaders hungry? I'll treat all the leaders to dinner. How about boiled mutton?"
