On the afternoon of September 21, when a passerby was passing by the Superman Building, he suddenly stopped at the corner, leaned over, turned over the pockets of vegetables, and left.
Muyu couldn't be sure whether the other party was Xia Yihan, Chu Yu stared at the screen twice, and said unequivocally: "It's her, it's her!"
According to the other party's walking direction, Muyu immediately retrieved the corresponding video, only to see Xia Yihan calmly crossing the road, and finally walked into the opposite supermarket.
Chu Yu's heart was boiling, and he was about to go to the supermarket for monitoring. Muyu expressed concern: "If she pays in cash, she won't find anything, right?"
"Not necessarily, she hadn't started committing crimes at that time, and her vigilance may not have been so high. I'll try my luck. You guys pay attention to how she got out of the supermarket, and see if you can find out her general destination."
The supermarket opposite has a certain scale, and Chu Yu is still confident in the length of the monitoring and preservation. After all, the Public Security Bureau requires it to be preserved for at least one month.
Chu Yu found the person in charge, went to the computer room, and directly called the monitoring of the cashier according to the time. The person in charge was going to adjust the cashier records, but Chu Yu saw Xia Yihan dressed in bf style, and strolled around the supermarket. Then he walked out leisurely and didn't buy anything.
She spit out turbid air from her nose, looked at the back in the monitor, couldn't do anything, and had to bring Song Qingyang back without success.
When he returned to Superman, Muyu had left the screen and got together with Fang Datuo to discuss things.
Seeing Chu Yu coming back, they both cast curious glances at the same time, wondering how Director Chu's battle is going.
Chu Yu pulled out the chair and sat down, looking calm, "I can't find anything over there, how about you?"
Muyu reported the situation: "The target object came out of the supermarket and turned into the back alley, that is, the road to the coffee shop. There is an unmonitored area there, and it can't be tracked after that."
Chu Yu folded his hands in front of his chest with a complicated expression: "This is not a grand debut yet, and the awareness of prevention is so strong. Before committing the crime, I didn't know how long I had stepped on the spot, and I must have planned it without leaking.
"There are only ten days before Xiao Huaihua appeared in Jinshui Hospital in late September, but judging from her familiarity with the surrounding environment, she must have been lurking for more than ten days. Now that I think about it, I am really terrified. Been under surveillance for so long?"
Fang Datuo was focused and couldn't help but sigh.
Song Qingyang was a little surprised when he heard what he said: "Shouldn't she have been staying nearby since she disappeared four years ago, watching her every move here?"
Chu Yu touched his chin: "It doesn't feel like it, if she really lived so close to us, the residents and businesses nearby should know her or have some impression of her, but when the police wanted her, they received There is no one reliable in the report call.”
Muyu nodded: "Yes, and she knows so many things. She feels that as long as it involves crimes, she is proficient in everything. Although Mao Yi has taught her a little bit subtly, this thing needs to be practiced, not just theoretical foundations. , Otherwise, if you watch a few crime movies, you will become a master criminal?"
Before she could finish her words, she saw Chu Yu staring at her intently, his eyes meaningful.
Muyu was silent, and was selectively silent.
Song Qingyang stood behind Chu Yu and played the role of breaking the deadlock again: "Then if the past experience of Bawanghua is investigated, will she be sentenced more severely?"
Chu Yu: "..."
After a long while, she turned her head and looked at Song Qingyang's little face from the bottom up, "It's okay, the truth is important, and we have to find out no matter what."
After she finished speaking, she turned to Muyu: "You just said that she turned to the alley behind the supermarket. If I remember correctly, turn right at that place, and walk a hundred meters. It's the ICBC ATM?"
Muyu opened the map, and all the banks were marked on the map, as well as the monitoring coverage of the corresponding route.
"The day she appeared was September 21. Do you want to check the bank surveillance on that day?"
Chu Yu pressed his brows with his hands, feeling that his brain power was in urgent need of recharging: "She appeared in our surveillance area that day, and she probably won't go to the bank. I remember that she was admitted to Jinshui Hospital on October 1, when she was still in the hospital. There is a man who pretends to be his father and helps her register and pay, if Xia Yihan hires him, he will also pay in cash to prevent us from digging up her information after we dug him out."
Fang Datuo: "Could that man be X?"
"This possibility is not ruled out, but our current assumption is that Xiao Huaihua is acting alone. She has planned everything before October 1, and has found employees. Then she needs to remind the other party that if she wants to use cash, then cash It should also be provided by her. The last time we checked the monitoring on October 20, that is, Xiao Huaihua's movements after escaping from Jinshui Hospital, but there was no gain. She may have prepared it before, and now it is near before October 1. The time is an important opportunity for her to prepare, after all, she will start committing crimes after that, and she will be exposed to the police, so she should minimize the number of times she appears in special surveillance."
Muyu listened to her and drew the key points, "Around October 1st, that is, from September 28th to September 30th?"
"Yes, we have a limited number of people now, and we are still investigating the range we drew last time."
Because of yesterday's investigation, they have already accumulated experience. This time, they are much more familiar with their actions. It's just that the person in charge of the bank is puzzled. It's only one day, why did the police come to the door again? I haven't heard of any major economic cases recently.
This time, Muyu used the face recognition system to go through it first. When Xia Yihan was tracked across the country, the Sky Eye system was used. The front end of the video surveillance continued to capture and video. Because of the lack of Xia Yihan's ID photo, the back end entered the photo taken by Chu Yu. The real-time comparison between life photos and monitoring will trigger the alarm system after the two are successfully matched, and notify the nearest public security organ in the area to arrest Xia Yihan.
But Xia Yihan ran away for two months, and the Sky Eye System was stunned to catch her. On the one hand, Chu Yu sighed at her level of stepping, and on the other hand, she marveled at her disguising skills, which was comparable to full face plastic surgery!
She even wondered if she was carrying a jammer with her, making the wireless monitoring equipment stop working.
Sure enough, after a comparison of Muyu, the system was only sorted by similarity, and it did not match 100%.
Chu Yu smiled helplessly, and changed positions with Muyu: "I'll do it. When will I develop a personal eye recognition system."
"Face recognition" is Muyu's forte. This time, she didn't surprise the four. She was a little disappointed and stepped aside with a blank expression.
After the monitoring has been processed, all faces have been individually selected, and the viewing time is saved. Now the main content is "guessing the person by looking at the picture".
Just looking at the picture, Chu Yu pulled very fast, and it was over in more than an hour. Muyu hadn't reacted yet. When he saw the display of "the last picture", his eyes were blank—doesn't this indicate that they were emptied again? Really got candy and got slapped again!
She was about to exit the interface when Chu Yu slapped her palm on the keyboard to stop the operation.
Muyu looked at her, not knowing why, is this confused
Chu Yu whispered: "Don't look at the screenshots, watch the surveillance video, the original video!"
"Three days, three banks, are you sure?"
Chu Yu nodded.
So Muyu played the 54G high-definition "movie" to her and let her watch it slowly. There are eight more sequels to follow.
Chu Yu watched intently, Muyu was tired from sitting, so he stood behind her, feeling like a woman who was determined to check all the surveillance cameras in the city, and wanted to break the Guinness record for the number of surveillance cameras.
From noon to the afternoon, almost three hours, without coffee, Muyu was sleepy, sat on the sofa at the reception, and took a nap.
She slept for an unknown time, and when she woke up, she found that it was a little dark. Chu Yu sat beside her, closed her eyes, crossed her hands, rubbed her thumbs slightly, and seemed to be waiting for the result. Seeing her like this, Muyu felt like she had already slept. One billion.
"found it!?"
Chu Yu nodded, but he didn't open his eyes, he used his eyes too much, and everything looked blurry.
Muyu couldn't believe it for a while. In terms of accurate recognition, the human eye is actually better than the sky's eye
It’s like giving two QR codes with only one slight difference. If someone comes to look for them, they may be holding a magnifying glass, and they can’t find them even if they are blind, but the machine can recognize them clearly in less than a second.
Muyu, a techie who has always advocated technology, couldn't help but ask humbly: "How did you do it, do you remember some of her obvious facial features?"
But these machines are better at it!
The corners of Chu Yu's lips rose, with a smile on his face, because he closed his eyes, his face became more peaceful: "I know some of her small movements are small details, just like I recognized her in the surveillance this morning, because Her habit of walking."
Muyu's mouth was slightly opened, and he didn't know what to say for a while, but Chu Yu actually completely defeated the computer this time. But in fact, the Tianyan system is very perfect. It can not only recognize the facial features of people, but also the posture and height, and input the images captured by the monitoring system into the face recognition system. Cloud information such as personnel database can be said to be sparse and not missed by Skynet.
However, when the appearance and posture are completely changed, it is a new technology to be developed through subtle habit action recognition, such as a special bank teller surveillance camera, which has the function of detecting and recognizing abnormal human behavior, but is also sensitive to dangerous actions, such as Holding a gun, holding a knife, etc., it is also impossible to accurately identify other personal movements.
Xia Yihan definitely didn't expect that even if she changed her face, Chu Yu would still dig her out of the crowd.
The bank manager took out the result and handed it to Chu Yu: "Hello, this is the information you want."
Chu Yu took the information, which contained Xia Yihan's bank account, transaction records, bound ID card account number, and phone number.
When Chu Yu saw the bound ID card, he was a little stunned for a while, thinking that his eyes were blurry, so he gave the information to Muyu.
Muyu scanned it and shook his head at her.
So the two hurried back to Superman's office. With the feeling of "waiting for the doctor to announce how long they can live", Muyu boarded the intranet, entered the ID number, and inquired about this person's information.
When the complete information page was presented, the two of them stared at the screen. Muyu was always expressionless, and Chu Yu didn't know what to make. They looked at each other as if they heard the doctor say, "After I announce, you may It's gone."
