After the two women came over and were polite, Xu Zheng and Zheng Heming began to draw sketches for them, one from the front, two from the side, and one from the back. After drawing, Xu Zheng asked them to sit down and said, "Two sisters, next I need to touch your heads, okay? Very carefully."
The two women looked at each other in disbelief. What are they going to do?
But seeing Xu Zheng's clear eyes, they all agreed, "Okay, just treat it like you're giving us a massage."
Xu Zheng called Han Xin and Lu Kexin in again and asked them to be witnesses. After everything continued, Xu Zheng stretched out his hands and touched the back of their heads.
He touched her very carefully and very slowly. Han Xin felt sour when she saw it, because Xu Zheng was not so careful and focused when he touched her.
The two women were a little nervous at first, but then they kept praising Xu Zheng for his excellent craftsmanship. Han Xin will be blessed in the future... Only Zheng Heming and Qi Guangyuan knew what Xu was doing, but they definitely couldn't say it at this time, because Xu Zheng was mainly touching. It's their skulls.
The only reason Xu Zheng touched them so slowly was to feel the size of their skulls, the flow of blood vessels, and the tension of their muscles and scalps.
Xu Zheng finished the work in 20 minutes. They were still curious and asked Xu Zheng what it was for. Xu Zheng said casually, "Touching like this can increase the three-dimensional sense of my painting and make it easier to draw portraits."
After seeing them off, Xu Zheng hurriedly returned to the study. Now he has master-level skull restoration technology. Now he wants to make the skulls of these two women one by one based on the bone touching and sketching just now, and then in this Based on this, make a computer 3D model.
To be honest, the task of restoring the skull was troublesome and time-consuming. Master Zheng Heming and his apprentice could not help much for the time being. Xu Zheng asked them to eat and rest first. He should be able to finish it in two hours.
The best way to make a living human skull like this is to first create a 3D computer model and then print it directly. Unfortunately, there is no such machine in Changming City, and you have to go to the Magic City and Kyoto. Xu Zheng can also make it himself. Of course there are errors compared to machines.
This took more than an hour, and it was almost nine o'clock in the evening. Seeing that Xu Zheng had completed the task, Qi Guangyuan picked up the camera and took pictures of the two skulls, and then transferred them to computer graphics software to generate 3D images. Model.
Comparing the skull models of the two women with the skull model of the trafficker, the display is very clear on the computer. What can be done now is to average the difference between them, so that a new skull data can be obtained.
There is a high probability that this figure is similar to that of the female trafficker. Of course, this is a matter of probability. When it comes to how big it is, Xu Zheng can only say 70%.
Qi Guangyuan worked for more than 10 minutes, and finally the 3D model of the skull came out, followed by the generation of skin, flesh and hairstyle. Finally, a frontal photo of a 37-year-old woman appeared on the computer screen.
"Master Zheng, Brother Qi, what do you think of this picture?" Xu Zheng asked.
Zheng Heming laughed, "This kind of model based on the real person's resemblance is definitely more accurate than the Yangcheng police based on the woman's back on the video."
Qi Guangyuan also laughed and said: "I think this method is okay. Besides, didn't the Yangcheng police find this female trafficker? Why talk so much? Let's just give it a try."
"Then what are you waiting for? Send this photo to the person on duty at the city bureau quickly and ask him to help us check it." Xu Zheng patted Qi Guangyuan on the shoulder and urged loudly.
Waiting is the most anxious thing, especially after you have worked hard for so long and put in so much effort, and there are more than 200 women looking forward to it. Xu Zheng suddenly felt a little stressed.
Five minutes later, colleague Qi Guangyuan sent over a piece of information queried on the intranet, "Ding Lijuan, born on October 2, 1982, ID number:...Home address: Guishan Province...
He was arrested by the Truong Binh Provincial Police on August 12, 2029 and charged with human trafficking and causing disability. Participated in the abduction and trafficking of XX women and children, and is currently being held in Trung Binh Province Women’s Prison. "
Qi Guangyuan looked at it first, then handed the phone to the master, and said excitedly to Xu Zheng: "Haha, I didn't expect our trick to be really effective. Master, do you have any ideas this afternoon?"
When Xu Zheng heard that he had accurate information, he hurriedly went over to check the information on his mobile phone. At this moment, he also became happy and automatically ignored Qi Guangyuan's last sentence.
Zheng Heming was also smiling at this time. He asked Xu Zheng to calm down and said seriously: "Xiao Xu, I think it is feasible to write a paper using the method we used today.
Although our current Sky Eye algorithm for automatically identifying suspects can find suspects with the support of big data, it always encounters various problems in reality.
In the past few years, many people who look like suspects have been arrested by the police repeatedly. This is not just one thing. Also, the Sky Eye system is very powerful, but there are still more suspects at large.
The reason is that its algorithm is not perfect, especially when it comes to processing the suspect's back.
This time, we compared the suspect's back with a live model, and then used skull modeling to generate an average skull model. This method is worth studying. If it doesn’t work well, it’s still a good project.
Xiao Xu, are you interested? Let’s do this project together.
Don’t worry, when the paper comes out, the name of the second author will be yours. "
Xu Zheng understood that it would be great if Zheng Heming could be the second author. Papers are in deep water. The more advanced the paper, the more valuable it is. The water is deeper. "Master Zheng, please give me a hand and give me a shout if you can use my place."
Although Xu Zheng is not engaged in theory or technology, he has a senior thesis, which is always a qualification, right?
After the three of them finished talking about the matter, Xu Zheng walked out of the study. Lu Kexin came over with a look of excitement and confusion, "Officer Xu, is there any result?"
Xu Zheng smiled, took out the information on his mobile phone and handed it to her, "We can only help you so far. Whether he is this human trafficker or not, you have to go to the Yangcheng police for help. This photo and information cannot be used as evidence by the court." side evidence, but can be used as evidence in police interrogations.
If the Yangcheng police accept this information, they will go to Zhongping Provincial Women's Prison to interrogate Ding Lijuan. "
I can't say I'm 100% sure about finding out information about a woman trafficker like this. I'm at least 90% sure, but I can't be too sure. What if?
Lu Kexin obviously understood what Xu Zheng meant. In her heart, this Ding Lijuan was 100% the human trafficker she had been searching for for 15 years. "Officer Xu, thank you, thank you, thank you, woo woo..."
At this time, Lu Kexin had already burst into tears, and she squatted on the ground and cried for a long time. No one could persuade her. Zheng Heming and Qi Guangyuan saw this situation, smiled, and secretly said goodbye.
After seeing them off, Han Xin and the others asked Xu Zheng after persuading Lu Kexin, "Xiao Zheng, can I send this information to the WeChat group?"
"Of course, Ding Lijuan has been sentenced to life imprisonment."
When Han Xin sent the message to the WeChat group, the group exploded, and all the divers came out. Soon their replies became unified, "Officer Xu 666!"
