The large-function conference hall of the Provincial Picture Scout Corps has an 84-inch spliced monitor screen. One wall of the conference room is covered with screens. They can connect to the Sky Eye cameras in various cities and regions across the province at any time.
Xu Zheng led the special team members here just to monitor suspicious people through this giant spliced display screen.
There are nearly 200,000 cameras controlled by the police in Changming City. There are so many cameras that even a dozen of them would not be able to see them all even if they were a hundred times more.
Therefore, Xu Zheng and the others only checked the cameras at traffic intersections and security checkpoints such as highway intersections, airports, and railways. Their main job was to identify Qiao Keyuan and Yan Hongqiang.
Because he was worried about Qiao Keyuan's disguise, Xu Zheng arranged in advance for the Internet police technical department to temporarily add an analysis program to the Sky Eye system.
Just compare the ears of all the women who appear on surveillance cameras, and of course Yan Hongqiang. No matter how brilliant the disguise technique is, the ears will not be adjusted, and human ears are as unique as fingerprints. They can also be used to identify a person instead of fingerprints. After adding this search program to the Sky Eye system, it can completely identify Qiao Keyuan.
The only thing that is difficult to do is that if Qiao Keyuan is wearing a hat and her hair covers her ears, she will not be able to identify her.
In this case, we can only rely on our colleagues who set up traffic jams at the intersection to find a way to take photos for identification. Xu Zheng also contacted taxi companies across the city and set up voice recognition programs in their walkie-talkie systems. If Qiao Keyuan takes a taxi, as long as she speaks, her voice will be automatically entered into the system for recognition. If there is a match, it will naturally be possible to locate her. her position.
Unfortunately, those online ride-hailing companies all use platform software and do not have a voice interaction system, so this voice recognition program cannot be used.
In addition, Xu Zheng also asked Dai Ruhai from the Special Police Corps to contact the city's special police detachments and special police brigades to be on standby in each district at any time. If Qiao Keyuan's location is discovered, he is guaranteed to arrive at the scene within five minutes.
A leader of the Scout Corps was very cooperative with Xu Zheng and his team's work. He watched them arrange one by one, including the ear recognition program and the voice recognition program. Coupled with the recognition function of the Sky Eye system, this can be regarded as an all-round solution. to find the target person.
"Team Leader Xu, my eyes have been opened today. These small programs have been used to the extreme." Xu Zheng smiled bitterly and said: "Mr. Zhang, I am also using chicken feathers as arrows. It is all the leaders of various departments who give me face. You Look, I want to use the ear recognition program. The internet police didn’t say anything and directly sent a dozen technical police officers to support me. Look at you, didn’t you also assign forty or fifty picture scouts to me? Yes. Without the support of a leader like you, no matter how capable I am, I can't complete the task." Zhang Xiangwen is only about forty years old and has already become the deputy chief of the map reconnaissance corps. He relies not only on connections, but also on his own in the map. He has made a lot of contributions in terms of detection.
"The Sky Eye system works well, but it also has flaws. For example, this time you specifically matched the ear of the target person. This is a very good idea. But the cost is also high. Look, without the help of so many technical police, this ear The recognition program can't run, right?" Xu Zheng understood what he meant. The Sky Eye system is networked across the country, and its servers are no less used than those used by Taobao and JD.com. It's all money. If you temporarily add an ear recognition program, it can be done in one night. It would cost hundreds of thousands more.
This does not include the subsidies for the technical police. He didn't dare to calculate it carefully. He estimated that the cost of handling the case tonight would be at least half a million yuan.
The same is true for taxi companies. Fortunately, they rent servers from several companies and run a walkie-talkie system. The cost is evenly shared. Helping the police temporarily add a voice recognition program will not increase the cost much.
Xu Zheng and Zhang Xiangwen stood in the corner of the hall chatting for a while before being called over by Gao Fangben from the Criminal Investigation Corps.
"Come quickly, Team Leader Xu, we have discovered something."
"Mr. Zhang, let's go take a look." When Xu Zheng rushed to the map scout Gao Fangben mentioned, he found that the electronic real-life map displayed on her computer screen was very familiar. Good guy, this is not near their home. , that street behind the Public Security Family Courtyard?
The picture scout was a lady in her thirties. When she saw Xu Zheng coming over, she quickly explained,
"The camera at this intersection just now recognized the back of a woman, and her ear contrast similarity was the highest at 82.19%, triggering the alarm system. I immediately monitored the woman's route, and several other shots did not capture her face, mainly because she Wearing a hat." Xu Zheng was originally very happy that the ears matched, but when the scouts monitored the woman and finally walked into the Public Security Family Home, he became worried again.
"Sister, please find me some shots of this woman and let me take a look." The eldest sister skillfully took screenshots of the shots and saw that some of the shots were a bit blurry.
"Team Leader Xu, would you like me to refine these screenshots?" Xu Zheng stopped her and smiled confidently,
"Thank you, eldest sister. No need. I can just identify it with my naked eyes." The eldest sister came back to her senses when she saw Xu Zhengxiao's confidence. She almost forgot that the person in front of her was a famous simulation portrait expert.
After looking at the two screenshots, although the woman was wearing a hat, she could still see clearly below her nose. It was certain that this woman was not Qiao Keyuan, and she was walking in the wrong way. He waved his hand in disappointment.
"Sister, please continue, this woman is not." Naturally, Zhang Xiangwen and Gao Fangben had no objection to Xu Zheng's judgment. In terms of recognizing faces, the young man in front of them can definitely be regarded as the first person in Changming. They had no doubt at all,
"Team Leader Xu, if the target person wears long hair over his shoulders, covers his ears, and doesn't take a taxi or go out of the city, what are you going to do?
"Faced with Zhang Xiangwen's question, Xu Zheng smiled and said: "If the first plan fails, I will try another one. If I can't catch Qiao Keyuan today, I have two more tricks, play hard to get and lure you into the urn..."
"Then what?" Zhang Xiangwen asked immediately when he saw Xu Zheng stopped mid-sentence. Zhou Fangben is a big man from Northeast China. He hates other people's displeasure the most. He spat directly in Xu Zheng's face: "You know how to show off your skills. If anything happens, just shake it out of the dustpan and it will be over. You still do it all, you If you do this again, my brother will ignore you."
"Brother Zhou, you can't blame me for this." Xu Zheng was also aggrieved. He quickly distanced himself from Zhou Fangben. This brother must have been angry and had bad breath.
"I reported it to the leaders, but they wouldn't let it go out. If there is really no other way, then we can implement it. How about you ask Mr. Liao?" A person who can sit in the position of deputy captain of the Criminal Investigation Corps has a kind of majesty. Zhou Fang didn't dare to look for Liao Hai, so he glared at Xu Zheng.
"Look for Mr. Liao, forget it, I'd better endure it for one more night, and so does your kid. If you can't say anything, don't let it go."
"Well, we've just finished talking here." Xu Zheng knew that Zhou Fangben had a bold personality and would not really be angry with him, but he quickly explained to Zhang Xiangwen,
"Mr. Zhang, the mission must be kept confidential. I hope you will understand." Zhang Xiangwen nodded to express his understanding, waved his hand, and asked Xu Zheng and others to get busy with their work first.
At this moment, the forty or fifty picture scouts in the entire hall, plus a dozen people from the temporary special team, all made discoveries one after another. However, the ears discovered were only 90% similar at best. After Xu Zheng personally identified them, he judged that they were all the same. Not Qiao Keyuan.
In addition to the suspected Qiao Keyuan, there was also Yan Hongqiang. Unfortunately, Xu Zheng saw that they were not the real ones. He turned to Zhou Fangben and asked,
"Brother Zhou, have your colleagues at the railway and highway areas responded to your messages?" Zhou Fangben looked at his phone, shook his head, and sighed.
"I guess Qiao Keyuan and the others haven't seen the fake news that they were arrested."
"This should be impossible." Xu Zheng said firmly, thinking that Qiao Keyuan must have approached Yan Hongqiang with a mission, so she and Yan Hongqiang had been hiding for almost two months, and they must have contacted the organization behind her.
"If Qiao Keyuan doesn't come out today, it means she has seen through my plan today." Zhou Fangben looked at the time and saw that it was already eight o'clock in the evening. At this time, the long-bright sky finally darkened. The cameras at the intersection were illuminated by street lights, but The visual distance is also doubled compared to daytime.
"Let's wait and see, but if we can't recognize it after twelve o'clock, then..." After early morning, the number of pedestrians on the street dropped sharply. Qiao Keyuan chose this time to come out, so the risk was much greater than at eight or nine in the evening.
Xu Zheng also had a headache.
"Looking for two people in such a big city is not like finding a needle in a haystack, and the leaders won't allow the citizens of the city to be mobilized, otherwise..." Zhou Fangben twitched the corner of his mouth,
"You are talking nonsense. How can you allow us to mobilize citizens? By the way, is there any news from the immigration detachment?" Xu Zheng looked at his mobile phone, but did not receive a call, and there was no response on WeChat.
"It seems that the people who flew directly from abroad to Changming today are very honest, and no other abnormal conditions were found among them." For these foreigners, it is naturally impossible to monitor them all the way. We can only check their check-in information to make inferences. At this point, it is difficult to find out who among these people will contact Qiao Keyuan.
The two chatted about their love while waiting for a miracle to happen. Unfortunately, until after ten o'clock in the evening, there was still no good news. The ear recognition system could not match, the voice recognition system did not work, and the Sky Eye system could not recognize Qiao Keyuan. and Yan Hongqiang.
Police on duty at railway, highway and other checkpoints did not find the target person. At this time, we should really let the police patrols, special police patrols, and security brigades of various police stations sweep the streets. Unfortunately, the leaders above do not agree.
Just when Xu Zheng was disappointed, Long Chuchu suddenly jumped up and shouted excitedly to Xu Zheng: "Director, come and listen, there is a female taxi passenger here whose voice is more than 80% similar to Qiao Keyuan... ." Upon hearing the good news, Xu Zheng quickly ran to her and put on his headphones. Long Chuchu operated the computer and repeatedly played the voice of the female taxi passenger.
"Master, go to the Consulate General of Lion City in Changming..."
