Police Detective

　　 The four groups of new duty systems are still showing initial results. Although there were fewer people yesterday, after more reasonable arrangements, Ren Xu and Bai Song both slept at night.

　　 At around 7 o'clock in the morning the next morning, Bai Song got up early and went to the cafeteria to eat. The criminal police and the crime team were preparing to arrest people. Bai Song saw Li Suo and was not in good spirits, so he went to ask what was going on.

　　 "I caught those two thieves yesterday, and I was so busy that they were not sent in until four o'clock in the morning." Li Yunfeng rubbed his temples: "There is a thief who has high blood pressure."

　　 "That's really troublesome." Bai Song understands that this kind of disease is a bit more cumbersome to enter the detention center.

　　 "I stay up all night every day, my blood pressure is 160, the thief is only 155, really, alas..." Li Suo sighed.

　　 Bai Song slept more than a little yesterday. At that time, the criminal detention procedures for the thief had been completed, but he did not expect that it would take a long time to be sent to the detention center.

　　 "You won't take a break," Bai Song said: "I have nothing to do today. If you need help, just say it."

"The three who worked overtime with me yesterday, I let them rest, but I can't rest." Li Suo said: "Then you go to the production base with me, but after the meeting at noon yesterday, I let them A few people went there and looked around again. They felt that it was of little value, and they might have already ran away."

　　 "Why didn't you go in yesterday?" Bai Song was a little curious.

"That place is a small road that is not easy to walk, and when I see the building, there are some open areas nearby. If there are people inside, you will definitely be found when you go inside." Li Suo gestured the terrain with his hands: "The road connected to this trail is a road that has been in disrepair for a long time, but it is monitored, but the camera can't directly take pictures of the trail. We stayed nearby several times and we didn't see any cars coming in or out."

　　 "How big is the video range?" Bai Song was a little puzzled.

"It's just a video next to the intersection. The trail is not an official road, so there are no traffic signs," Li explained: "The road that connects to the trail has not many cars running, and there are also every day. Some trucks passing by, the highway is next to the highway, and the cars are afraid of tire wear, so they would rather go on the highway.

　　 "Is there monitoring, let me see." Bai Song asked.

　　 "Yes, in my computer, let's watch it in the car for a while. If you don't like the car shaking, you can watch it." Li Suo said: "It's a bit of a journey to go to that place."

　　 took the computer, in the back seat, Bai Song directly looked at it.

　　 This is a video for half a month.

　　 Watching video is really a headache. This is 360 hours of surveillance video. Even if you watch 16x speed without a pause, you have to watch for more than 20 hours without blinking. No one can handle it.

　　 "No, it's too much. Go to the detective. I'll find someone to get it." Bai Song was dizzy looking at hundreds of video recordings.

　　 "Okay." Li Suo is not in a hurry. If he visits the criminal police now, he will be able to chat with the second team about arrests. It is only half past seven.

　　 By the time it was eight o'clock in the Interpol Team, Bai Song took Li Suo's computer and found Wang Liang first.

"Do you mean to find out all the cars passing by here?" Wang Liang opened a video and found that there were big cars passing by basically every few minutes on the road. The angle of the camera was from the side, and I couldn't see it. To the license plate number.

"That's it," Bai Song said: "What I need to filter is the big cars with a speed of less than 20 kilometers per hour. This video can't shoot the small road I want to see, but all I need to go to The speed of the big car coming out of that road must be less than 20 per hour, because the big car has to brake in advance and the acceleration ability is also very poor, and the blind spot of this monitoring is only more than 20 meters away from that road.

　　 In addition to the road to go, there are large cars coming out of that road. For the others, the speed is above 40. There are few cars and pedestrians on this road, and big cars will not easily drop the speed below 20. "

　　 For a big car, speed is money.

　　 If you have a problem, you must slow down, but if you slow down and speed up when you have nothing to do, you will easily consume a few dollars and gas.

　　 "Okay, no problem." Wang Liang understood what Bai Song meant: "It will be done in the afternoon."

　　This is not difficult in computer programs. First of all, the current video processing software can capture specific moving pictures, and the passing of the truck is a specific moving picture, which is very conspicuous. Here you can only grab the moving picture as big as the big car, and let the small car go.

Suppose that it takes 5 seconds for a car with a speed of more than 40 kilometers per hour to enter and disappear from this surveillance camera, and a car with a speed of 20 kilometers per hour takes 10 seconds. Then through the software, delete the part of the animation that takes less than 5 seconds. Then manually select the ones below, there is no problem.

Very simple.

　　 Wang Liang directly started to disassemble Li Suo’s laptop.

　　 "Why is this?" Bai Song was startled.

"His computer is too slow. Even if it’s 30 megabytes per second, five or six hundred gigabytes of video will be copied out for a long time. If you want to use my computer for multi-threaded calculations, you must use my computer to operate," Wang Liang said:" Remove his hard drive, connect it directly to my computer with an interface, and use it as a mobile hard drive, so that you can open the video file directly on his hard drive, saving several hours."

"Well, just don't break it." Bai Song looked at Wang Liang's skillful technique, and he was afraid that he did not do anything less. It seems that his technique is also getting more and more adept~www.novelmtl.com~ This kid is not bad. If this is unemployed, it is estimated that going to repair the computer will be enough to eat...Bai Song murmured a few words, and left the house of the third team.

　　...

　　 The people who are going to be arrested today are not that easy to arrest. Several of them have good anti-investigation awareness. The Criminal Police has also done a lot of preliminary planning and received some technical support.

　　 Of course, Zhang Che is easy to catch, he is idle every day, and can catch whatever...

　　 If it weren't for worrying that "Second Brother" might confide in Zhang Che, just ask him where Zhang Che is, and then call him over.

　　 After catching those people, Bai Song didn't go. Ren Xu was still in the office to make up his mind. Before 8:30, Bai Song came out and it was all right. Ren Xu couldn't do it.

　　He finished the handover with Wang Liang here, and Li Suo also finished talking with the captain of the second team. The two took the five team members from the office and drove two cars and went to the base first.

　　 This place is in the suburbs. After driving dozens of kilometers of road, the car entered this highway.

There is a highway nearby, so this small road is basically deserted. There are very few cars. After Li has been here several times, the cars can drive up to 40 or 50, and they can fall apart soon, and there are some pits. The car has a bad view, and it is not easy to avoid it.
