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

After all, Kanazawa is more capable than Xu Zheng.

He went out for a walk, and when he came back he suggested that Xu Zheng go find Liu Jianghe, "Xiao Xu, our plan probably won't work out. All 76 map scouts will not be in place until seven o'clock tomorrow morning.

This is what I think. Let’s go to Shizhuang Zhengding International Airport now.

Well, in the name of the Escape Bureau, I went over to inspect it in advance.

Anyway, all airports have already been notified. If we go, we only need to bring our own documents.

But you have to ask Liu Hall for approval. "

Xu Zheng did not respond immediately, but was wondering if he could check the cameras at each entrance and exit by connecting to the airport police station if he did not go to the scene.

It seems to work too.

But it’s certainly not as intuitive as on-site.

"Then let's go now..."

"Xiao Xu, you should go find Liu Tang by yourself." Kanazawa smiled awkwardly and explained: "You are in a special situation now, and it will be dangerous to leave the capital.

If I follow you, Liu Ting will definitely know that I dragged you away. "

Danger?

After Xu Zheng came to Beijing, he subconsciously ignored the issue of his own safety. He was confident that no one would dare to harm him here.

As for leaving Beijing, he still hopes that someone will come to make trouble. "Isn't Brother Jin afraid that following me will be dangerous?"

Kanazawa put away the cynicism on his face, put on a righteous look, and said in a strong and powerful tone, "I am a serious criminal police officer, and my ancestors were also first-class guards with swords.

A little bit of cheating just helped me achieve my annual target. "

When Xu Zheng heard this, he also became interested, "After all, you are still a descendant of the Eight Banners, a descendant of the royal family."

"Hey, is it okay to slap me in the face? That's my ancestor. In today's society, I can't stand this name."

"Okay, let's stop talking nonsense with you. I'll go to Liu Hall to report on my work first."

Liu Jianghe didn't stop him, he just reminded Xu Zheng to pay attention to his safety and to go to work on time at eight o'clock tomorrow morning.

Shizhuang Zhengding International Airport is not far from the capital, just past Baoding City and further south.

The whole journey was on high speed and took more than two hours.

On the way, the two first contacted the Bac Ha Provincial Fugitive Recovery Office and asked them to send someone to assist.

When they arrived at the airport police station, Director Chen Yuanwen of the Bei Ha Province Fugitive Pursuit Office was already waiting here.

The three of them greeted each other politely before Xu Zheng got down to business.

"Director Chen, that's it. I guess you also received the notice from the ministry about the action at eight o'clock tomorrow morning.

The two of us rushed here in advance, mainly because we wanted to get familiar with the situation of the international airport in your province.

Well, just a little experiment. "

Chen Yuanwen is not yet 40 years old, a little chubby, wearing glasses, he looks very polite, and he is very enthusiastic. He smiled and said: "Why don't you call me Director Chen? I'm a stranger. We are about the same age. You can just call me by my name."

Let's go to the police station and I'll introduce you to the leaders here.

All police cameras in our airport area are connected to the province-wide SkyEye system.

The upgrade has been completed and our colleagues are testing it. You can come over and conduct experiments. "

As long as the Sky Eye system is not upgraded to new functions across the entire province, it will not take too long.

Moreover, most of the police cameras at the airport are in public areas such as surrounding intersections, entrances and exits, parking lots, shopping malls, etc.

There are more than 1000 cameras in total.

More than 50 monitoring stations.

The security personnel in these monitoring stations are actually equivalent to map scouts. Therefore, for tomorrow's operation, the airport police station has already negotiated cooperation with the airport security company.

Next, Xu Zheng and his wife, accompanied by Chen Yuanwen, met with the director and instructor of the police station here.

After another polite exchange, everyone gathered in the multi-functional surveillance hall. Looking at the large screen with a 300-yuan display hanging on the wall, Xu Zheng took the lead and said unceremoniously:
"Chen Chu, Wang Suo, and Instructor Zhao, we have to go back to the leaders in a while, so we will ask our colleagues to do their best for the next test."

It was all work. Chen Yuanwen knew who Xu Zheng was and what he was capable of. After hearing this, he couldn't wait to introduce it to a group of people at the airport police station: "I have long heard that Director Xu has extraordinary abilities.

Catching a Class A wanted criminal is like picking something out of a bag.

You don't know yet, do you?
The May Day operation he presided over captured three A-level wanted criminals in Changming in just three days.

13 Class B wanted criminals.

There are countless ordinary wanted criminals left..."

Xu Zheng smiled bitterly and interrupted quickly, "Goodbye, Chen Chu, please spare me. I am not so powerful. It is all the result of everyone's hard work.

To count too many would be an exaggeration. "

After getting along for a while, the chat between the several people became more and more intimate. In addition, one party wanted to ask for something, and the other party wanted to make friends. Under the arrangement of Kanazawa, a master of field control, the atmosphere of the conversation was like meeting old friends.

Director Wang is the "landlord" here. He quickly arranged for his men to gather a group of photo scouts, and then asked these photo scouts to assign cameras to the areas they were responsible for.

Following the order, the improvised team could barely support this afternoon's experiment.

Soon, hundreds of small screens on the big screen displayed scenes captured by various cameras at the airport.

Some people drove to the airport, some were pulling their luggage in the parking lot, some were going through security check, some were queuing up to change their tickets...

There were 68 flights at Zhengding International Airport this afternoon, including 27 international flights. Basically, more than a dozen flights took off and landed every hour, so the entire airport seemed very busy.

"How's it going, Xu Chu, have you found anything?"

Not even 5 minutes later, Chen Yuanwen asked curiously.

Xu Zheng felt helpless. Now that people all over the country know that police cameras can scan people's skulls, there must not be many wanted criminals who dare to come to the airport.

"Chen Chu, you are also an old man in our fugitive pursuit system. This nationwide operation is only limited to the airport, railway and ports. The scope is too small. It is very likely that we will not be able to find even one Class A wanted criminal at the end of the day."

"This is what you said." Chen Yuanwen said as if he was complaining or suggesting: "The leaders above asked us to lock up the wanted criminals in the country.

This is of course no problem.

But if we want to catch wanted criminals, I think we still need to upgrade the nationwide Sky Eye system immediately.

Especially in vast rural areas…”

Anyone with a discerning eye knows this issue.

Xu Zheng felt that he was complaining that the leaders above did not implement a major upgrade of the nationwide Sky Eye system at one time, but adopted a partial upgrade strategy.

But the leaders above have their concerns and plans, whether it is staffing or the servers required for system upgrades...

And the most important issue is funding.

Before Xu Zheng could reply, Jin Ze changed the topic with a smile, "Wang Suo, how many wanted criminals can our Sky Eye system find within one year?"

Director Wang looked embarrassed and glanced at Instructor Zhao next to him.

The instructor understood and said for him: "Generally, at most a dozen are discovered a year, and at least none are found.

Maybe most of the people who fly in China are wealthy people.

How dare these people come to the airport after knowing that they have committed a crime.

You must know that there are many more surveillance cameras at airports than at railways, shopping malls and other places. "

This situation should be similar across the country. After all, every airport is built tall and has all the security facilities inside.

Let’s not talk about anything else, let’s just talk about the police station. Basically, every international airport has a dedicated one.

Kanazawa sighed, "If you put it this way, if you search for Class A wanted criminals at the airport, you may not find even one case in a year."

Chen Yuanwen glanced at Xu Zheng and saw that he was carefully observing the big screen. He became discouraged and talked about his previous point of view.

"In this operation, I think it is impossible to catch those A-level wanted criminals. It would be good if we could catch a few B-level wanted criminals and complete a few more targets."

Not only Chen Yuanwen thought this way, but even Jin Ze thought the same way.

It is true that no one is optimistic about this action.

Including Xu Zheng himself.The same goes for the leaders above. It would be easier to upgrade the Sky Eye system directly across the country, and they have to carry out local actions.

Although it is said that the purpose is to close the door and beat the dog in the future, but now, they, the case investigators, all feel unsure.

Xu Zheng also knew that complaining was useless, and he was thinking about how to maximize this operation on the way here.

But he still didn't figure it out after all.

"Ring Ling Ling…"

Suddenly, Director Wang's cell phone rang. He took it out and saw that it was his superior. He quickly confessed to Xu Zheng and others and hurried out to answer the phone.

After a while, he hurriedly walked in again.

With a serious face and anxious eyes, he looked at Xu Zheng and said, "Director Xu, we have a temporary mission here, which will delay your experiment for a while. Please..."

Xu Zheng immediately stepped aside and said, "Your work is important, please.

By the way, do we need to avoid it? "

Director Wang waved his hand quickly, "No need to avoid it, I'll probably have to trouble you all later..."

As he spoke, he took over the command of the airport Sky Eye system and gave orders to the airport police station police and airport security personnel through the headset.

It turns out that Director Wang received instructions from above that a certain deputy city manager might leave Shizhuang City by plane, and the airport police station needed to stop him at the airport.

Xu Zheng and Jin Ze listened to Director Wang's arrangements. He asked people to go to all boarding gates, parking lots, and ticket gates of the airport for manual and AI recognition...

"Have you never seen this kind of mission?" Jin Ze couldn't help but ask when he saw Xu Zheng's curiosity.

Xu Zheng was amazed, "I've seen this kind of sudden interception mission on TV.

I really haven't experienced it. "

Chen Yuanwen no longer smiled on his face. After all, the person intercepted this time might be the deputy mayor of Shizhuang City. Maybe he knew him.

He steeled himself and kept his facial expression, "Xiao Xu, tell me, if you were the deputy mayor, how would you escape from here?"

Xu Zheng didn't know what he meant. He had nothing to do now. He thought about it and replied: "There used to be a very popular TV series. It seemed that a deputy mayor named Ding used another set of real passports to take a plane and fled abroad. .

Now, this method is still valid, after all, the ticket checking process is the same as before.

As long as the passport is authentic, other issues such as facial recognition, manual and AI recognition are not big problems.

After all, the existence of twins reduces the power of facial recognition.

However, now that the airport police station has received the news, I think the people who escaped can also guess this.

Then he must not dare to board the plane with his real face to check the ticket.

what can we do about it?

I think in addition to using disguises and 3D hoods, I also use other people's identities to board the plane.

There should be no other way. "

No one can sneak into a plane with so many cameras. Even Xu Zheng himself has no way to secretly board an international plane in broad daylight.

Kanazawa slapped his thigh, "Hey, it's a coincidence. The Sky Eye system at the airport has just been upgraded today, so I can verify whether it works well."

Xu Zheng actually wanted to say this just now, but he had a concern because the previous skull scan had not found a wanted criminal wearing a 3D hood.

The 3D hood is actually very thin and fits tightly to the scalp and face. With a little makeup, it can completely cover the marks on the eyes, nostrils, and mouth.

The skull scan is a 3D modeling graphic automatically generated by the background system after the camera takes a photo of the target.

Therefore, although the hood is thin, it covers the hair, and the part of the skull will cause errors in the person's real data.

Of course, Xu Zheng has not done any specific testing as to the specific error.

But now the arrow is on the string and must be fired. Since there is an upgraded Sky Eye system, how can Director Wang not use it.

However, he arranged for all the police officers and cameras to check the airport, but no trace of the target person was found.

He even asked the airline to notify the captain who had not yet taken off and search the waiting cabin.

But still no good results.

Seeing that it was only 20 minutes before the latest plane took off, Director Wang became anxious.

He has the right to delay an international flight for a while, but this time cannot be too long, and he still needs to apply with the airport...

All in all, it's a troublesome thing.

Because the plane takes off one minute late, those foreign friends on international flights will complain, and international airlines will also complain...

Director Wang watched the time passing by and realized that the upgraded Sky Eye system might not necessarily be useful.

He picked up his cell phone, reported to his superiors, and requested to contact the airport to extend the departure time.

However, during the call, he glanced at Xu Zheng, and before hanging up, he asked: "Director Xu, I heard that you are an expert in pursuit of escapees.

If you were put on a plane, could you identify the target person we want to arrest at a glance? "

At this critical moment, Xu Zheng did not hide his strength and nodded confidently, "I can do it!"

Director Wang immediately made a report and requested the airport airline to allow police from the police station to board the cabin for inspection.

It probably takes no more than 10 minutes.

Xu Zheng waited until Director Wang hung up the phone and suggested: "Please also ask Director Wang to send the video of the passengers checking in on this plane to the big screen.

At the same time, let the Sky Eye system record the 3D model of the target person’s skull.
Then compare them one by one..."

Director Wang was surprised: "You...you mean you can search the target without boarding the plane?"

Xu Zheng smiled confidently: "It's not that I can, but the new Sky Eye system can.

Now is not the time to explain, please give the king's instructions first. "

Director Wang no longer hesitated, and quickly asked people to do as Xu Zheng said, using the 3D skull model of the target person to compare all the passengers who had boarded the plane.

It was all computer operation. Five minutes later, there was a sound of police officers typing keys.

Soon, the videos of the passengers on the plane that was about to take off, including the stewardess, the captain and the captain, and the passengers landing on the plane were all re-screened by the Sky Eye system.

However, after the screening, the Sky Eye system still did not sound an alarm.

There is no alarm sound, which means that the target person has not been compared.

"Director Xu, look? How about we go to the engine room to check first?" Director Wang became a little anxious when he saw this situation.

Xu Zheng smiled and said: "Isn't the result coming out? Watch it on the big screen."

At this time, the comparison results of the 446 passengers on the plane and the target person appeared on the big screen.

Because the contrast ratio of the Sky Eye system exceeds 60%, the alarm will sound, and the maximum for these passengers is only 52%.

Seeing that everyone was very confused, Xu Zheng briefly explained that the 3D model of the computer-generated character itself had some errors.

In addition, the target character has now changed his appearance, using a 3D hood and a human skin mask.

“Because the new Sky Eye system has added skull scanning skills, the domestic skull database is not yet complete, plus the hood and face used by the target person.

So no alarm was raised…”

Anxious Director Wang interrupted Xu Zheng's explanation, "You mean, the person with this contrast ratio of 52% is the target person we are looking for."

"That's right!" Xu Zheng gave a positive answer without hesitation, "Director Wang, I am personally proficient in simulated portraits, and I can judge it just by watching the video.

The white man on the plane with white skin, brown hair, and a height of about 180cm is the target person you are looking for. "

Seeing the hesitation on Director Wang's expression, Kanazawa added: "Many people in our system know Director Xu's abilities.

If Wang Suo can't make up his mind, he can make second-hand preparations.

One is to send someone to the cabin to verify.

The second thing is to report truthfully to the leader. "
