Retracing the Police Path 1993

It took the next day for XCMG to make progress.

In the afternoon of the next day, Xu Gong received an email from the Ministry's Physical Evidence Center, printed it out immediately, and brought it to Liu Pengcheng: "I just said, the composition is so complicated, it is durable and light, and it is really a big brand!"

Liu Pengcheng took it and saw that it was the reply from the Physical Evidence Center, including the composition and molecular formula of the original physical evidence, and the composition and molecular formula of the sample found by the Physical Evidence Center.Also included is the sample case.

It is a mid-to-low-end running shoe with a cool appearance created by Nike for the millennium.Teenagers, mainly middle school students, are the main sales groups. Of course, they are "international big-name millennial fashion" in China.The price is not cheap!
According to their company's statistics, the sales of this shoe in Hangzhou are not bad. From the launch on New Year's Day to one month ago, a total of more than 170 pairs were sold.

This shoe is the same style for men and women. Of course, there are men and women in the sales. Since this shoe is mainly red, women buy more in China.

Liu Pengcheng has seen this kind of shoes in many places. It is hard to believe that Quan Yuhang has sold more than 100 pairs. It is still Xiaogu who said that the imitations have to sell thousands of pairs!
In fact, Xiaogu is right, even some domestic brands have launched similar shoes.

But what Liu Pengcheng had in his hands was the result of testing the material of the sole, so it couldn't be an imitation.Finding suspects from dozens of people is actually very difficult!
Xiaogu drove the car, went to the Municipal Bureau with Liu Pengcheng, and found Zhao Detachment.

Team Zhao held the reply letter from the Ministry's Physical Evidence Center in his hand, and his face was about to burst into laughter.

That's easy!

After giving the results of the appraisal to Team Zhao, they declined the dinner, and Liu Pengcheng and the others returned to the center.

When he got off work, Liu Pengcheng suddenly remembered why Xiao Zhai hadn't moved at all these days!So I went to Xiao Zhai's studio, but there was no sound inside.

Liu Pengcheng knocked on the door, but nothing happened.

So Liu Pengcheng opened the door directly, but there was no lock, so he opened it all at once.So he saw Xiao Yang sitting on a large computer chair, wearing a huge headset and sleeping in the dark.The lights in the room were not turned on, and the light from the 19-inch Philips flat-screen monitor made his face and his open mouth flicker on and off.

Liu Pengcheng walked over to take a look, and was stunned.

The monitor is playing the surveillance video at the intersection of the old Zhao’s community at eight times speed, and then automatically pauses from time to time, grabbing a frame with a motorcycle and automatically storing it.

This, this, this, the god himself came out with the picture detection software? ? ?

Liu Pengcheng took off his headset directly.

Xiao Zhai continued to sleep, but Liu Pengcheng didn't wake up after pushing.

Liu Pengcheng had no choice but to whisper in his ear, "Dinner is ready!"

Now Xiao Zhai woke up, his eyes widened, and he wiped the drool from his mouth with his hand: "I'll order braised pork!"

Then I saw Liu Pengcheng with a black line on his face, and looked around again before realizing what was going on.

Xiao Zhai was a little embarrassed: "Director Liu, I've stayed up late these days"

"Okay, okay, I know you forget to eat and sleep. Let's go home and eat braised pork with me."

Xiao Zhai said: "I won't bother you, I can just have a bite in the cafeteria, and I have to come back later."

Liu Pengcheng said: "Don't talk nonsense. Just look at what time it is, and there are only a few good dishes left in the cafeteria."

At that time, the canteen of the Police Academy was divided into a student canteen and a staff canteen.But in the evening, everyone basically goes home to eat, that is, the teachers on duty and a few unmarried ones eat in the cafeteria, so the amount of dinner prepared is not large, and often the faculty and staff who go late can only eat fried rice, noodles or quick-frozen dumplings.

Xiao Zhai thought about it, and went back with Liu Pengcheng.

Liu Pengcheng really didn't fool Xiao Zhai, his family did eat braised pork at night.Stewed vermicelli with braised pork.

The soft and rotten pork belly that has been stewed and the chewy wide noodles are a perfect match!
Xiao Zhai cooked three bowls of rice in a row, and drank another bottle of soda before he patted his belly in satisfaction: "Oh, after this meal, I think I can eat biscuits and instant noodles for another week."

Liu Pengcheng said: "You are just lazy, the cafeteria is only a few steps away from our center!"

Xiao Zhai said: "You don't understand, once you start typing the code, you can't stop."

This Liu Pengcheng really didn't understand, but he still said: "Even if I don't understand, I know it can be preserved!"

Xiao Zhai's eyes widened: "You should finish typing all at once. Go to the cafeteria to have a meal and then stroll back. If you can't catch it, you can't catch it, do you understand?"

Well, Liu Pengcheng really doesn't understand.

Tietou didn't understand even more.After eating, I went to play with toys by myself.

After Liu Pengcheng and the others finished their meal, Aunt Xu made tea for them. It was Liu Pengcheng's favorite jasmine tea. Xiao Zhai had been working in the capital for a long time, so he was naturally used to drinking it.

Liu Pengcheng said: "So in order to find out the motorcycle, you made an image screening software yourself?"

Xiao Zhai said: "It's not difficult, but it takes a lot of effort before grabbing. You need to input various parameters, images, and computers. To put it bluntly, it's dead. You ask him to find the same motorcycle, red, He can find what the front looks like. But once the side view appears, he won’t recognize it, so he has to enter it again. This is too laborious.”

After all it is not AI.

Liu Pengcheng said, "Can this problem be solved?"

Xiao Zhai: "This matter is labor-intensive, not difficult. We have to input a large amount of various data and have to update it frequently. It is too laborious. If someone else enters the relevant parameters, then when we use it, enter the motorcycle we are looking for. Or the model of the car."

Liu Pengcheng said, "Where's the human face? Is that okay?"

Xiao Zhai said: "In fact, this kind of software exists and has been put into actual combat, but it is in the stage of strict secrecy. I am afraid that it will not work if someone deciphers it and finds out a way to deal with it."

Liu Pengcheng asked: "Is it from the Great Beautiful Country?"

Xiao Zhai: "How safe is the beautiful country, how can I use this kind of thing."

Liu Pengcheng said to himself, wait until next year's golden autumn to see if you can still say this!

Xiao Zhai said: "It's from the country of David. They use this software to check whether there are fireworks people with big turbans among the people entering the country."

Liu Pengcheng said, "Have you ever thought about what we can do with this?"

Xiao Zhai said: "What can I do, what else can I do? Didn't you ask me to find a snitch? I did this?"

Liu Pengcheng had no choice but to tell Xiao Zhai about the function and working method of the map investigation.

Xiao Zhai's eyes widened: "Brother Liu, why don't you tell me a sci-fi story? With the resolution of the camera, how can it be as good as you said? It would be great if it could tell whether a human head is round or not. How is it possible to directly identify the identity. Even if there is a high-definition camera, what is the cost? Not to mention other places, just say Yuhang, how many can you afford?"

When he said this, Liu Pengcheng also came to his senses.This is 2000, this year, digital cameras have just entered the era of 300 million pixels!Still can't shoot at night.This year, all mobile phones still have black and white screens, and occasionally a few blue-ray screens are considered black technology!
Liu Pengcheng was still reflecting on his "great feat", but Xiao Zhai said: "But I think with the development of technology, there will always be a day when your vision will be realized. Now it is difficult for us to screen people, but it is not a problem to screen cars!"

Xiao Zhai suddenly opened the door to the new world, and felt that he had made a very good software, so he dragged Liu Pengcheng back to his office to check the pictures of several motorcycles that often appeared near the crime scene. Video screenshot.

Seeing the first one, Liu Pengcheng was stunned.The red shoes worn by this rider are so familiar!
