"Comrade policeman, what do you call it?" Meng Xiaobai asked.

"My surname is Sun. The other party said.

"Officer Sun, the person who stuffed the card into her house goes to her house every day, if you look at the surveillance video, you should be able to find something, right?" Meng Xiaobai asked.

Officer Sun smiled helplessly and said, "There are no surveillance cameras in the corridors of the Meisheng Village community, only the entrances and intersections of the community have been installed with monitoring. There are so many people coming in and out every day, how can you find this?"

"And it's a whole week of surveillance, more than a dozen cameras, 24 hours a day, even if you arrange people to watch, you can't see it even if your eyes are spent. Our police resources are limited. Besides, you're losing something! It's not a big case!"

"What if something happens?" Meng Xiaobai asked rhetorically, "If that person has bad intentions, won't my friend be in danger?"

"No way, there are some petty thieves around here at most. Officer Sun was unimpressed.

Su Lianyue looked at Meng Xiaobai, and her eyes were clearly asking, "What now?"

"Don't worry. Meng Xiaobai comforted, "I'll help you find him!"

"How are you looking?" said Officer Sun.

"Officer Sun, let's take a look at the surveillance video at the intersection, is it okay?" Meng Xiaobai asked.

Officer Sun was a little impatient, but in line with his duties, he said: "Yes, you can, but I will explain in advance that you can't find anything." It's not like we haven't seen it, and we haven't found any suspicious characters. ”

"I'll talk about it after watching it. Meng Xiaobai said.

Officer Sun called up the surveillance video on the computer, there were twelve surveillance screens on the screen, Su Lianyue was dumbfounded when she saw it, there were people coming and going from time to time in each surveillance screen, and anyone who looked at it felt that something was wrong. And they're looking for a whole week's worth of footage, how can you see that?

"Don't think about it, if you can't find it like this, go back and wait for us to inform you, and we'll tell you when we have clues." Officer Sun said with a smile, he thought that the two would give up if they pulled up the surveillance footage.

Meng Xiaobai didn't give up and said, "I will definitely find it." ”

"Okay, you can only watch here. Officer Sun was not in a hurry, he estimated that in another ten minutes, when the two of them were dazzled, they would give up. If it's so simple to solve a case, what else do they need professionals to do?

"Brother Meng, how can I find this?" Su Lianyue felt that her eyes couldn't see at all, since she looked a week ago, and she just saw suspicious characters, she thought that she couldn't remember so many faces in her head.

"Don't worry, I'm here. Meng Xiaobai's tone carried inexplicable confidence, which made Su Lianyue feel a lot more at ease.

"Su Lianyue, when that person stuffed a postcard into your house, was it day or night?" Meng Xiaobai asked.

"It should be night!" Su Lianyue analyzed, "I never saw it during the day, it all appeared early the next morning, it must be night." ”

"At night, the camera can't shoot clearly, if you want to distinguish it with the naked eye, find possible suspects from 12 cameras, a week, and nearly 2,000 hours of surveillance footage, and you can't use conventional methods!" Meng Xiaobai touched his chin, "It seems that you can only use some advanced means!"

"Advanced means?" Su Lianyue looked at him curiously, what else could be done about this?

"Wait a minute. Meng Xiaobai went to the toilet of the police station and whispered to Xiao Maruki: "Xiao Maruki, can we use the program to find out the suspicious target from the surveillance video?"

Maruko's voice sounded in his ears, "Of course you can, master!" As long as we set the range, such as Su Lianyue's sister's address, the time of the crime, the frequency of appearance, etc., and then compare the characters, we can find the most suspicious person." But I need to be the core processor. ”

Even if you can make this program, if you want to process so much information, it is not something that a simple small program can do, and you must rely on the advanced intelligence of Maruko to process it.

"Okay, Maruko, send me this program right away. Meng Xiaobai said.

"No problem, master!" Maruko immediately began to generate intelligent programs.

At the police station, Officer Sun was chatting with several police officers while working.

"Those two people really didn't give up, and really went to watch the surveillance video. Officer Sun was speechless and said, "What can they find, I have their surname!"

"Haha, these people, it's too simple to solve the case. Just like in their case, how can the suspect be found? There is no surveillance in the corridor, and there is no other information, and all appearances, ages, and genders are all black! Officer Zhang smiled slightly.

"Let them see. "Otherwise, they wouldn't have given up." ”

"Well, that's what I thought. Officer Sun said, "People who have not undergone professional training want to find clues in the 2,000 hours of surveillance video, and they are afraid that they will not be able to see anything if they are blind." ”

At this moment, Meng Xiaobai came over and asked, "Officer Sun, discuss something with you." ”

"Look, he gave up. Officer Sun looked at his colleague with an expected expression.

"What's the matter?"

"yes, I'm a programmer, and I've written an information search program. I want to use this program to retrieve footage and it will automatically help us find the most suspicious people. Meng Xiaobai said.

"What? and such a thing?" Officer Sun didn't believe it, "Are you kidding?"

"I'm not kidding, my stuff is in the network disk, as long as you download it, you can use it. Meng Xiaobai said seriously.

Several police officers next to him also heard his words, and Officer Zhang was puzzled: "Is there such software? Why haven't I heard of it?" ”

The female police officer said: "I know about the Sky Eye System, but the Sky Eye System doesn't seem to have this function. Can you do it with your own applet?"

"Absolutely!" Meng Xiaobai swore assurance, "As long as you use it, you can do it in a minute." We're all convenient, and maybe we'll be able to crack this case. ”

Officer Sun was still very hesitant, and Meng Xiaobai continued: "If you are afraid that the video data will be damaged, I will give you a backup, a matter of a few minutes!"

"Okay, I don't believe it, can you still find suspects with this software?" Officer Sun walked over, "Isn't that more powerful than our police?"

"Just look at it. Meng Xiaobai began to prepare.

He first backed up the video data, and then began to download the program that Maruko uploaded to the network disk.

"I'll say okay, this is the police station, if you download some virus and break our computer, get an education on the spot!" Officer Zhang said jokingly.

"Then if I solve the problem, can I be rewarded?" Meng Xiaobai said in a relaxed tone.

"If you can solve the problem, I'll give you a certificate of honor!" Officer Zhang said.

Several police officers surrounded Meng Xiaobai to see what he was doing.

"What are you doing? Isn't it working time?" shouted one of them behind his back.

Several officers looked back and saw that it was their captain who had arrived.

"Team Zhou!" Officer Sun explained, "This little comrade said that he has a software that can find clues about the suspect in the video materials, and we will see if it is bragging." ”

Captain Zhou was in his forties and burly, with more majesty than these ordinary police officers.

"Nonsense, if there was such a thing, it would have been used by us a long time ago!" Captain Zhou scolded, he didn't believe it either.

"Comrade policeman, this is not necessarily, I developed it exclusively. It's going to be good right away. Meng Xiaobai had already put the video data into the program, set some conditions, connected to Xiao Maruko through the network, and began to conduct intelligent analysis and screening.

"Can it work?" Su Lianyue looked at Meng Xiaobai at work, feeling a little nervous, especially being watched by a group of policemen.
