Wutong Branch of Jiangbei City.

Office of the Criminal Investigation Team.

Gao Cheng took the picture provided by Gu Chen to Gan Wenfeng, and asked Gan Wenfeng to run errands in the dispatch room, and launched a dragnet search according to the time and place of the girl's last time getting off the bus.

And Gu Chen, Lu Weiwei and Officer Wang sat in a row drinking milk tea.

The milk tea was bought by Gao Cheng, and he also wanted the three of them to sit, and the rest would be handled by his own people.

In this way, it will not appear that the police in Jiangnan City will be anti-customer-oriented.

After all, exchange and learning is also an opportunity to understand each other's strength.

In fact, Gao Cheng has long seen that in this exchange and learning team, Lu Weiwei is a foodie.

As long as it's a foodie, it's easy to do, and if you can do it with a few cups of milk tea, don't be stingy.

Eat and drink well, don't make trouble for yourself, don't give yourself blind command.

"Senior Brother Gao. Looking at his watch, it was almost noon, but there was still no news, Gu Chen couldn't help but ask more: "Can the monitoring be done over there?"

"It can be done, of course it can be done. Gao Cheng also patted his chest and promised: "The efficiency of our Jiangbei City police, you can rest assured, proper, as long as we find the whereabouts of this girl, we can notify you immediately." ”

"But. Gu Chen put down the empty milk tea and hesitated.

"What? Do you want me to buy you something to eat and drink?" asked elevation weakly.

Gu Chen waved his hand and said, "Senior Brother Gao, I didn't mean that, I just wanted to say, since there is a positive picture of this woman, why not use face recognition to search for it?"

"Face recognition, just this picture?" Gao Cheng thought Gu Chen was joking.

After all, the screenshot of this on-board surveillance video can only take a frontal photo of the girl from a top-down angle, which is a bit far-fetched in itself.

Not to mention the use of high-definition photos of the front face to carry out massive screening, which is difficult to see.

At this time, Gan Wenfeng also happened to walk in lazily, picked up the thermos cup on the table, went to the water dispenser to pick up a glass of water, sat back in his seat and drank it gurgling.

"Wen Feng, how is the situation?" Gao Cheng hurriedly asked him.

Gan Wenfeng waved his hand, and said slowly: "I found some clues, but the surveillance video is incoherent, in some key places, the monitoring is blocked by some obstacles, and it can't be continued." ”

"That is to say...... There's no way to find the woman's whereabouts?" Gu Chen said.

Gan Wenfeng turned his head to look at Gu Chen, and then nodded: "It's about the same situation, at that time, according to the on-board monitoring and the monitoring of the bus station, we can find that the woman got off the bus at 7 o'clock in the evening, and it happened to be Liu Xun's No. 11 bus, but 15 minutes later, she lost contact in the monitoring blind spot of an alley." ”

"Of course, we also tried to find out from several places around the area that were monitored, but to no avail. ”

Gao Cheng also quickly explained: "I know those streets, some of the surveillance has long been broken, and some are old equipment, and the picture is not very clear." ”

Seeing that several people continued to stare at him, Gao Cheng smiled and said: "Isn't this because of financial problems? Many old equipment has not been upgraded, and all of them are blind spots, but I didn't expect that this girl disappeared in the blind spot of monitoring." ”

"Then the next day, did she appear in the video of her disappearance before?" Gu Chen also hurriedly asked again: "After all, this is the route she often takes, and there is no reason why it will not appear." ”

"I checked. Gan Wenfeng crossed his hands on his chest, lay on the seat and said: "That place, including the next day, and today, we have all done a comprehensive investigation, and our eyes are almost swollen, and we have not found any trace of this girl at all." ”

Seeing everyone's disappointed faces, Gan Wenfeng also said helplessly: "There is no way, after all, monitoring is not omnipotent." ”

"Let's do face recognition. Gu Chen saw that the surveillance investigation would not work, so he had to determine the girl's identity through face recognition.

It's okay not to say this, but when I say it, Gan Wenfeng, who was originally disappointed, suddenly felt incredible.

Gan Wenfeng's expressions were the same as Gao Cheng's just now.

This kind of picture of looking down on the front face will cause a large error if face recognition is required.

Because of the different angles, it is difficult to locate the picture accurately.

Therefore, the error caused by the computer in recognition may be further expanded.

In the vast sea of people, looking for a needle in a haystack like this is useless at all, so Gan Wenfeng feels that Gu Chen is just talking about it, and this kid doesn't know what face recognition is.

"Senior Brother Gan. Seeing that Gan Wenfeng's expression was still sluggish, Gu Chen reminded him again.

"I can't get this. Gan Wenfeng cocked Erlang's legs and said in a non-negotiable tone.

Seeing that his partner Gan Wenfeng was a little emotional, afraid of affecting unity, Gao Cheng also smiled and explained: "I'm sorry, it's not that we don't want to operate like this, it's really difficult to operate, without a more accurate face, the computer can't closely calculate all angles, and the screened characters will definitely be invalid." ”

"This is equivalent to asking you to count how much hair the other party has, how many stars there are in the sky, it's difficult to achieve the effect in practice, don't you say?"

Seeing that Officer Wang nodded frequently in understanding, Lu Weiwei and Gu Chen did not react at all.

Therefore, Gao Cheng asked the three of them weakly: "You three, can you do face recognition?"

Officer Wang waved his hand: "I can't do it, I can't get this thing." ”

"Hehe, think about it, this thing is too high-end, saying that it is a machine, in fact, it has to rely on people to analyze it themselves, which is very troublesome. "Seeing that Comrade Lao Wang can't operate it, then Lu Weiwei and Gu Chen are even more impossible.

So Gao Cheng asked Lu Weiwei again: "Officer Lu, do you want to come?"

"I can't. Lu Weiwei, as expected by Elevation, also waved her hand and refused directly.

She has a few pounds and a few taels, but Lu Weiwei still carries it clearly.

Seeing that neither of them could do it, Gao Cheng looked at Gu Chen, and he also had no hope and said, "Since your two senior brothers and senior sisters are not good, then you Gu Chen ......"

"I'll come. ”

Before Gao Cheng could finish speaking, Gu Chen had already stood up and asked weakly, "Which computer do you use?"

Elevation was stunned.

Gan Wenfeng was also stunned.

The two of them were stunned on the spot, and they couldn't hold back a smile in their hearts.

The heart said that Officer Wang and Lu Weiwei can't do it, you can do it as a third-level superintendent who has just joined the police for more than a year?

Isn't that the case for bragging?

"Gu Chen, don't be reluctant if you can't do it, when the time comes, you will screen out tens of thousands of files, then when do you want to compare them one by one?

Gan Wenfeng said that he had never seen such a showy policeman.

Old comrades know the way of modesty, but this guy is a reckless master, and it's time to let the facts slap him in the face and let him know the limitations of face recognition.

As a result, Gu Chen took out his mobile phone and began to use the picture editing software that came with the mobile phone to take a screenshot of the on-board surveillance video and start using the software to edit.

The picture that was originally looking down in the direction is raised in three dimensions until it is adjusted to a parallel direction.

Although at this time, the face of the picture has been somewhat distorted, but the photo is head-up, which meets the standards of face recognition.

"So it can still be like this?" Gan Wenfeng, whose neck was stretched out like a giraffe, couldn't help but be surprised when he found that after Gu Chen edited the picture, he was already looking at the picture at a heads-up.

However, after seeing that the photo was a little distorted, I was secretly happy in my heart, and I said that I would use this distorted picture for face recognition, which is too exaggerated.

"Senior Brother Gan, do you have any sketching paper and pen in the office?" Gu Chen hurried to Gan Wenfeng after finishing editing the picture.

Gan Wenfeng was stunned again, and asked weakly, "You...... What do you want?"

"I care about the pen and paper that my brother and sister are drawing. Lu Weiwei was afraid that Gan Wenfeng didn't understand, so she hurriedly repeated Gu Chen's request loudly.

"What do you want to do? It's face recognition now?" Gan Wenfeng suddenly began to hesitate, and said to himself, Gu Chen, what do you want to do?

"Just ask if you have one, right?" Lu Weiwei also urged again.

At this time, Gao Cheng reluctantly responded: "It seems that there is something in the office, you wait for me here, and I will come when I go." ”

After saying that, Gao Cheng walked to the bookcase in the corner of the office, and after a while of pounding inside, he finally found a roll of sketch paper and a bundle of sketch pencils.

Gu Chen directly took out one, used the knife in the plastic box on the table, sharpened the sketch pencil, and sat directly on Gan Wenfeng's seat.

Gan Wenfeng was stunned for a moment, turned his head and wanted to communicate a few words with Gao Cheng beside him, but was forbidden by Gao Cheng's direct booing, and then turned his attention to Gu Chen.

Gu Chen picked up his phone, took the edited photo, and blinked it twice.

"Click!"

Suddenly, the people in the mobile phone photos were directly photographed by Gu Chen with his eyes.

"The Face Recognition skill (Elementary) has been activated. ”

Under the prompting of a beautiful mechanical female voice, Gu Chen turned on the primary skill of face recognition.

"Image acquisition complete!"

The mechanical female voice prompted again.

At this moment, the originally somewhat distorted picture began to become clear and three-dimensional in Gu Chen's mind.

The reason why the mobile phone software is used to edit the angle of the character is actually Gu Chen's trick, which makes everyone believe that although the photos they see so far are distorted, they are also face pictures.

And then, in Gu Chen's mind, the three-dimensional picture began to become clearer.

Gu Chen had already completed the image acquisition work in an instant......

Subsequently, Gu Chen deliberately put the mobile phone in front of him, pretending to be a reference, and began to draw.

In fact, Gu Chen's painting references are completely three-dimensional pictures in his mind.

This kind of reference engraved in his mind can make Gu Chen's painting confident.

After a few moments, the outline of the figure is roughly clear.

After a while, the shape of the figure's face and the proportions of each place began to become clearer.

After a full 6 minutes, Gu Chen had already put down the pen: "Okay, that's basically what it looks like." ”

Elevation: "......"

Gan Wenfeng: "......"

That's it?

Sketch in 6 minutes?

Gao Cheng and Gan Wenfeng looked at each other, feeling that this is some kind of treasure policeman? A sketch can be done in 6 minutes?

And both of them looked at it carefully, and this kind of sketch seems to be different from what they usually see.

The three-dimensional effect of the various shadow surfaces seems to feel that the opposite side is not a painting, but a person looking at you intuitively.

It's kind of scary.

Gan Wenfeng was stunned, and asked weakly: "So...... Are you going to use this sketch for face recognition?"

"Otherwise?" Gu Chen asked him rhetorically.

In fact, this sketch can be seen as a black and white photograph.

The characters painted by Gu Chen are vivid and very realistic.

Elevation was a little unsettled, and he hurriedly said, "Then ...... Then try it, it won't take much effort to try anyway, Gu Chen, you use this computer. ”

Elevation pointed to a seat next to him.

"Okay. Gu Chen picked up the painting, didn't think much about it, and walked directly to the computer.

After sitting down, Gu Chen first used his mobile phone to take sketch pictures, then put them on the computer, and then turned on the face recognition system.

Gao Cheng hurriedly attacked his body, crackled and knocked a few times, the unlocking was completed, and Gu Chen could let go of his hands and feet to operate.

The others, holding their breath, gathered around Gu Chen.

Gu Chen used the sketch uploaded to the computer as the basis to start the system screening.

In an instant, a large number of photos began to flicker on the right side of the sketch picture.

It took less than ten seconds for a picture of a person's face to appear on the right.

Everyone stepped forward and looked at the screening chart that popped up by the system.

"Oh my God!" Gao Cheng couldn't help but exclaim, "This ...... That's too similar, isn't it?"

"It's just the same, it's just the same. Gan Wenfeng, who was on the side, couldn't help but sigh with emotion:

"This ...... What kind of immortal skill is this? A distorted screenshot of a surveillance video can be drawn so three-dimensionally, and it only takes 10 seconds to screen out the characters with the highest degree of matching, how is this done?"

And Lu Weiwei and Officer Wang, who were behind them, also looked at each other after discovering that they were the tallest figures, and couldn't help but high-five in celebration.

Gu Chen didn't pay attention to everyone's excitement, but directly clicked on the profile of the person with the highest degree of matching.

Suddenly, a clear profile form was presented in front of you.

"Zhang Xiaoya, female, 23 years old. ”

"He is 165cm tall and weighs 50kg. ”

"Occupation: Dance teacher of Xiangtian Dance Studio. ”

......

Gu Chen kept reading out Zhang Xiaoya's basic information softly.

And Lu Weiwei couldn't bear it, and then after scanning the information below, she said: "It turns out that Zhang Xiaoya is from the surrounding counties and cities in Jiangbei, and currently rents in Room 505, Unit 4, Building 16, Xinxing Community, and all of them are registered here. ”

"It's easy to have an address. Officer Wang also breathed a sigh of relief, feeling that Gu Chen's operation was okay and did not embarrass the Jiangnan City Police Force.

It was the hosts Gao Cheng and Gan Wenfeng, and the two were so shocked that they couldn't do it.

6 seconds can draw a three-dimensional sketch, which has killed most of the police officers in seconds.

And every stroke of Gu Chen is just right, no more and no less, just right.

In particular, the grasp of the shadow of the characters is simply to the point of being superb.

It's no wonder that a sketch can quickly identify the information of the person.

If you don't have a certain level of painting skills and a strong ability to understand characters, I'm afraid it's futile.

Now even the address of the other party has been found.

Gao Cheng felt that all the work he had done before was not the same as Gu Chen's coming this time.

I feel like this is being dominated by anti-guests again?

"Senior Brother Gao. Seeing Gao Cheng looking up at the ceiling, the whole person's expression was also dumbfounded, and Gu Chen kindly reminded him.

"Huh?" Gao Cheng instantly came back from his fantasy and hurriedly asked Gu Chen, "What's wrong?"

"Now that the rental address of Zhang Xiaoya, the subject of the investigation, has been determined, let's leave immediately, shall we?" Gu Chen said.

Gao Cheng rubbed his rumbling belly.

He originally wanted to go to the cafeteria to eat, but based on experience, the search would definitely not go so smoothly.

As a result, Gu Chen took 6 minutes to get the sketch and 10 seconds to filter out the character information.

Looking at Gu Chen's workaholic, Gao Cheng wanted to cry, and said that he couldn't eat this lunch.

"Alright, let's go now. ”

What else can elevation say? I can only follow Gu Chen.

Is this anti-guest again?

......

......

1 p.m.

The five people drove to the emerging community, and soon found 16 buildings with 4 units and room 505.

At this moment, the five people were standing at the door, Gan Wenfeng turned on the law enforcement recorder, knocked on the door, and asked, "Is anyone at home?"

The room was silent, and there was no movement.

Then Gao Cheng also stepped forward, grabbed the doorknob and pushed the door, and said, "It seems to be locked from the inside, and the door can't be opened." ”

"Could it be that this Zhang Xiaoya has already left the house in the past few days?" Lu Weiwei couldn't help but ask curiously.

Everyone looked at each other, unable to confirm it.

After all, Zhang Xiaoya's disappearance was the words of Liu Xun, the driver of the No. 11 bus, and he felt that Zhang Xiaoya's sudden disappearance was a little abnormal.

After all, in the days of daily contact with Zhang Xiaoya, Liu Xun felt that Zhang Xiaoya was a very self-disciplined girl, and even the time to take the bus was punctual, and the error would not exceed half an hour.

It is precisely because of the past three months that Zhang Xiaoya has delivered milk to Liu Xun every day, which makes Liu Xun pay special attention to Zhang Xiaoya.

Therefore, Liu Xun, who seems to be a little overly anxious, is actually not unreasonable in his worries.

"You can't kick the door, right?Who is this landlord?Can you get in touch?" Gu Chen hurriedly asked Gao Cheng.

Elevation is also undecided.

After all, following Gu Chen and the three of them to toss around, he didn't want to.

Now that Gu Chen has investigated and found out, can the woman who delivered milk to Liu Xun, the driver of the No. 11 bus, stop there? Obviously, no.

So Gao Cheng made another call to the substation.

"I'm Gao Cheng, you remember, help me find out who the landlord of room 505 is in this emerging community, 16 buildings and 4 units, yes, after finding out, help me send me the landlord's phone number, yes, immediately, what? You are still eating? Don't eat, eat less and don't starve, hurry up." ”

Hanging up the phone, Gao Cheng's eyes fell on Gu Chen, a treasure policeman from the Third Criminal Investigation Group of the Furong Branch of Jiangnan City.

Now Gao Cheng's eyes have changed when he looks at him, and he feels that this guy is staring at the door, is he thinking about something again?

......
