"What do you call comrade police?" Meng Xiaobai asked.
"My surname is Sun." the other party said.
"Officer Sun, the person who inserted the card into her home goes to her home every day. If we check the surveillance video, we 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 Meisheng Village Community. We only installed surveillance cameras at the entrance and intersection of the community. There are so many people coming in and out every day, how can we find them?"
"And it's a whole week of surveillance, with more than a dozen cameras, 24 hours a day. Even if you arrange for people to watch, you won't be able to see it. Our police resources are limited. Besides, you have lost something.
Well! It’s not a major case!”
"What if an accident happens?" Meng Xiaobai asked, "What if that person has evil thoughts in his heart, wouldn't my friend be in danger?"
"Impossible, there are at most some petty thieves around here." Officer Sun didn't take it seriously.
Su Lianyue looked at Meng Xiaobai, her eyes clearly asking: "What should we do now?"
"Don't worry." Meng Xiaobai comforted, "I'll help you find him!"
"You're looking for it? How are you looking for it?" Policeman Sun smiled.
"Officer Sun, can we take a look at the surveillance video at the intersection?" Meng Xiaobai asked.
Officer Sun was a little impatient, but in line with his duties, he said: "It's okay, but I'll explain in advance that you won't find anything. It's not like we haven't seen it before and haven't found any suspicious characters."
"We'll talk about it after reading it," Meng Xiaobai said.
Officer Sun pulled up the surveillance video on the computer. There were twelve surveillance pictures on the screen. Su Lianyue was dumbfounded when she saw it. There were people coming and going from time to time in each surveillance picture. Everyone felt that something was wrong. And they were looking for
It's a whole week's worth of footage. How can you see this?
"Did you see it? Don't think about it. You can't find it like this. Go back and wait for us to notify you. We will tell you if we have clues." Officer Sun said with a smile. He thought that the two people would give up if they brought up this surveillance picture.
.
Meng Xiaobai did not 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 ten minutes, the two of them would be dazzled and give up. If it was so easy to solve the case, why would they need professionals?
"Brother Meng, how are you looking for this?" Su Lianyue felt that her eyes couldn't see at all. She started looking at it a week ago, and even when she saw suspicious characters, she thought she couldn't remember so many faces in her mind.
.
"Don't worry, I'm here." Meng Xiaobai's tone was inexplicably confident, which made Su Lianyue feel at ease.
"Su Lingyue, when that person sent postcards to your house, was it during the day or at night?" Meng Xiaobai asked.
"It should be at night!" Su Lianyue analyzed, "I have never seen it during the day. They always appear early the next morning. It must be at night."
"At night? The cameras can't capture the picture clearly at night. If you want to distinguish with the naked eye, you can find possible suspects from 12 cameras, a week, and nearly two thousand hours of surveillance footage. Conventional methods will definitely not work!" Meng Xiaobai touched his chin.
, "It seems that we can only use some advanced methods!"
"Advanced means?" Su Lianyue looked at him curiously, what else can be done?
"Wait for me." Meng Xiaobai went to the toilet of the police station and whispered to Xiao Wanzi: "Xiao Wanzi, can we use the program to find the suspicious target from the surveillance video?"
Xiao Wanzi's voice rang in his ears, "Of course, Master! As long as we set the range, such as Sister Su Lianyue's address, time of crime, frequency of occurrence, etc., and then compare the characters, we can find the most suspicious
People. But they need me to be the core processor."
Even if this program can be made, processing so much information cannot be done by a simple small program. It must rely on Xiaowanzi's advanced intelligence for processing.
"Okay, Xiaowanzi, make this program and send it to me immediately." Meng Xiaobai said.
"No problem, Master!" Xiaowanzi immediately began to generate intelligent programs.
In the police station, Officer Sun was chatting with several police officers while working.
"Those two people really didn't give up and actually went to see the surveillance video." Officer Sun said speechlessly, "Whatever they can find, I will take their last name!"
"Haha, these people think that solving crimes is too simple. Just like in their case, how do you find the suspect? There is no surveillance in the corridor, and there is no other information. His appearance, age, and gender are all black!
I can't find it." Officer Zhang said with a slight smile.
"Let them take a look," said a female police officer, "otherwise they won't give up."
"Well, that's what I think." Officer Sun said, "If someone without professional training wants to find clues in two thousand hours of surveillance video, they may be blind and unable to see anything."
At this moment, Meng Xiaobai came over and asked, "Officer Sun, I have something to discuss with you."
"Look, he gave up." Officer Sun showed his expected expression to his colleagues.
"What's up?"
"Well, I'm a programmer. I've written an information search program. I want to use this program to retrieve video data, and then it can automatically help us find the most suspicious people," Meng Xiaobai said.
"What? There is such a thing?" Officer Sun didn't believe it, "Are you kidding?"
"I'm really not joking. My stuff is in the network disk. You can use it as long as you download it." Meng Xiaobai said seriously.
Several police officers nearby also heard what he said. Officer Zhang asked doubtfully: "Is there such software? Why haven't I heard of it?"
The female police officer said: "I know the Sky Eye system, but the Sky Eye system doesn't seem to have this function. Can the small program you made yourself do it?"
"Absolutely!" Meng Xiaobai vowed, "Just use it and it can be done in one minute. We are all convenient, maybe we can solve this case."
Officer Sun was still hesitant, and Meng Xiaobai continued: "If you are afraid that the video data will be damaged, I will just give you a backup copy. It only takes a few minutes!"
"Okay! I don't believe it. Your software can still find criminal suspects?" Officer Sun came over, "Isn't that more powerful than our police?"
"You'll know just by looking at it." Meng Xiaobai began to prepare.
He first backed up the video data, and then started downloading the program Xiaowanzi uploaded to the network disk for him.
"I promise, this is the police station. If you download some virus and damage our computer, you will receive education on the spot!" Officer Zhang said jokingly.
"Then if I solve the problem, can I get a reward?" Meng Xiaobai said in a relaxed tone.
"If you can solve the problem, I will give you an honorary citizen certificate!" Officer Zhang said.
Several police officers surrounded Meng Xiaobai to see how he operated.
"What are you doing? Isn't it working time now?" someone shouted from behind.
Several police officers looked back and saw that their captain was here.
"Team Zhou!" Officer Sun explained, "This young comrade said he has a software that can find clues about suspects in video materials. Let's see if he is bragging."
Captain Zhou is in his forties and has a burly build. He is more dignified than these ordinary police officers.
"Nonsense, if this thing existed, we would have used it long ago!" Captain Zhou scolded, and he didn't believe it either.
"Comrade police, this is not necessarily the case. I developed this exclusively. It will be ready soon." Meng Xiaobai had already put the video data into the program, set some conditions, connected to Xiaowanzi through the network, and started intelligent analysis
and filter.
"Is it possible?" Su Lianyue looked at Meng Xiaobai at work, feeling a little nervous, especially when she was surrounded by a group of policemen.
