At four o'clock in the afternoon, Xu Han's two small courtyards and living rooms were full of women, and if you looked closely, they were all 30-40 years old eldest sisters, and all of them were about 160 tall, petite and delicate.

This is all Tian Xinyue's use of her status as the deputy director of the neighborhood office and the height and approximate age of the woman trafficker in the family courtyard of the nearby Public Security Bureau.

As soon as these eldest sisters and aunts heard that they were going to make mock portraits of traffickers, they all enthusiastically signed up, and they also recruited relatives and friends.

At this time, Zheng Heming of the Provincial Department and Qi Guangyuan of the Municipal Bureau sat behind the desk in the corner of the small courtyard and waited.

As for Xu Zheng, he and Han Dongwen were debugging the camera, and this camera was finally found, because the current camera pixels are far more than 15 years ago, and almost all the relationships were activated, and finally it was found in the equipment warehouse of the provincial department.

Xu Zheng calculated the horizontal distance between the trafficker and the camera based on the footage of the 15-year-old camera, as well as the height of the camera, and now he carefully installed the camera to the height of the playground 15 years ago.

What he did was very simple, that is, to try to restore the scenes in the video as much as possible.

Now let the women play, as for the costumes, because it was the summer vacation, the hottest time in Yangcheng, so this time the women's costumes and props had to be as the same as the women traffickers.

White short sleeves, denim skirts, white sandals, ponytails, and suspected tattoos on the inside of the ankles, this tattoo Xu Zheng decided not to investigate, because the Yangcheng police have already investigated.

In fact, Xu Zheng can't say whether this on-site simulation can be effective, mainly because he wants to get as close to the three-dimensional sense and concreteness of this human trafficker as possible through this simulation.

When he told Zheng Heming, his old man was very interested, and the Chinese New Year's Eve personally rushed over.

Now the most exciting and bumpy is Lu Kexin, who has been staying at the scene and constantly thanking people with her hands folded, this woman said thank you more in the afternoon than in her life.

Especially when Xu Zheng shouted, the eldest sister stood in the place where Xu Zheng had drawn in short sleeves and short skirts in the winter, and let the camera collect background photos.

On such a cold day, all the cold shiverers have to insist on completing Xu Zheng's needs, these women are really moving, Han Xin recorded them, if Xu Zheng really drew a woman trafficker, she would post it on the Internet.

It's just a pity that the background and lighting can't meet the scene 15 years ago, so I asked Qi Guangyuan to come over, he is very proficient in mapping software, and the later work can be handed over to him to complete.

Han Xin also has a job, after each eldest sister takes a photo, she numbers people in order and leaves contact information, and if necessary, she has to communicate in time.

In this way, they took turns to stand for 3 seconds, plus the wasted time such as queuing and standing, and collected back photos of more than 200 people in half an hour.

Xu Zheng felt that it was okay to have so much, in fact, he was more inclined to believe that this woman trafficker was from Xichuan Province, because women in Xichuan Province were generally petite, why did they say that Xichuan produced beautiful women, the reason is that petite women are the first choice for most men.

Another point is that there are more poor people in the mountainous areas of Sichuan, Yunnan and Guizhou, and there are more cases of trafficking in women and children than in other parts of the country.

But Xu Zheng felt that his idea was a bit extreme, so he thought of the method of on-site simulation, if the back photo of the woman collected is highly similar to that of human traffickers, then this woman can be used as a template.

Xu Zheng and Lu Kexin were very grateful to send away the eldest sisters who came here to help, good guys, I don't know if it is Changming's enthusiasm, or hatred of human traffickers, or to support the work of the police, in these two hours, there are no less than 300 women who come to Xu Zheng's house, they are very conscious, bring their own clothes and sandals, and leave directly after they are done, basically not delaying Xu Zheng's affairs.

Of course, when you leave, you will always ask, "Xu family boy, don't forget to tell us when you have the result."

Of course, Xu Zheng gave an affirmative answer.

After sending away the women who came to help, Xu Zheng and Qi Guangyuan moved them to Han Dongwen's study, and Qi Guangyuan began to do 3D modeling comparison.

The 3D model of the back of the woman trafficker has been done for a long time, and now it is enough to enter these more than 200 pictures of the back of the woman into the computer for comparison.

Qi Guangyuan crackled and made comparisons, Xu Zheng was not idle, he used the materials borrowed from Lu Forensic Medicine to make the back of the head of the female trafficker according to the 3D model on the computer.

After all, 15 years ago, the image of the camera was very ambiguous, so there are still errors in computer modeling, and Xu Zheng will make a skull on the back of the head with the hair and scalp flesh removed on this basis, and the error will be even greater.

Therefore, he hopes that Qi Guangyuan can try to find out more than 90% of the restoration, so that there is a three-dimensional model here, so that he can simulate the skull of a trafficker and restore her appearance.

This is a complex and delicate work, and what they can do is to continuously reduce the error, and the less the error, the more similar the degree of restoration.

Of course, if there are more back pictures of women collected, the degree of restoration will be more similar, and it is impossible to restore them all, Xu Zheng They still have a clear understanding of this.

Xu did it based on experience, so, in order to be accurate, he did four or five at once.

After being busy for more than two hours, Qi Guangyuan's master and apprentice also made a model comparison.

I have to say that the computer is indeed more accurate than the human supervisor's idea, if Xu Zheng and they look at it with experience, how to find it must have dozens of similar ones, and the computer software gave two similar women.

It's seven o'clock in the evening now, and Xu Zheng is a little hesitant to invite someone over so late.

"Excuse me, they come early, let's make a portrait early, we can find the child earlier, and the reunion of mother and child is not the biggest thing?" Zheng Heming, who has always been gentle, changed his normal behavior at this time, urging Xu Zheng to quickly contact these two women.

Xu Zheng glanced at him a little suspiciously, this old man is not normal, forget it, it is important to do business first, he walked out of the study and told Han Xin the numbers of these two women.

Han Xin shouted directly in the WeChat group, and soon, the two women responded, saying that they would be there in a while.

At this time, Xu Zheng knew that Han Xin had specially set up a group for more than 200 women, and when Xu Zheng didn't come out, they were chatting about traffickers and Officer Xu in the group.

Some of these more than 200 women are from the family homes of the Public Security Bureau, and they are more or less the families of the police.

It can be said that their confidence in Xu Zheng is now 101, and participating in Xu Zheng's work has made them feel sacred and passionate.

They are just swiping their mobile phones for one task, and they are all waiting for the comparison results of Xu Zheng's side.
