Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 218

Lu Chuan knew that there are computers on the market that specialize in image processing.

These computers have high requirements on CPU, graphics card, and memory.

And it's not that the more expensive the better, but some hardware devices are suitable for processing images, but not necessarily suitable for playing games or doing calculations.

But buying it now will definitely waste time.

Most of these computers need to be assembled by themselves according to the needs, and there are ready-made finished machines, but in most cases it is not as good as professional assembly.

Of course, another reason is that the price is much more expensive.

If Lu Chuan bought it himself, he wouldn't care about the price, but the leader of the criminal investigation team obviously didn't think so.

"Master, can you borrow their computer from Tuzhen?"

Under the Haizhou Criminal Investigation Detachment is the Graphic Investigation Brigade, which was formed only in the last ten years.

Now, in the investigation of criminal cases, more and more rely on the discovery of surveillance video.

Some criminal acts were directly recorded by the surrounding surveillance cameras.

Therefore, the Picture Investigation Team came into being.

Surveillance cameras on the market have different brands, different quality, and different installation time. The quality of video shooting can be described as very different.

The high-definition cameras installed ten years ago and the high-definition cameras installed now have different standards for high-definition.

Some cameras work well during the day, but can only capture blurry figures at night.

Some cameras are obviously high-definition cameras, but due to lack of maintenance, the front of the lens is contaminated with dust and rain, and the shooting effect is not clear.

In the actual process of solving crimes, the police will encounter a variety of pictures or videos with different levels of clarity.

Most of these videos are not able to directly lock the appearance of the suspect.

Videos need to be informatized through technical means, which is the job of the Picture Investigation Brigade.

And judging from all the cases that Lu Chuan has come into contact with since joining the police, basically every case will involve the investigation of surveillance videos.

In some cases, due to the long period of time, the investigation video volume is quite large. It may be ten days or 20 days, or even one month. In some cases, the investigation can last for three months or even longer.

There are so many videos in one case, ten cases, one hundred cases.

Such a large amount of data can be described as astronomical.

Although Haizhou City Public Security Bureau has a large number of establishments, there are 138 members, plus auxiliary police and some contract workers, the entire figure investigation team has more than 300 people.

But even with so many people, it was still too busy.

This can also explain from the side the reason why Sun Yuting was defrauded in QZ City. Although the amount involved was large, the real identity of the suspect has not been determined through image recognition.

It's not unimportant, it's really too busy.

Plus... the technology doesn't work either.

Although Lu Chuan has not acquired image processing skills in the system, his image processing capabilities in advanced fingerprint skills identification and analysis are already very powerful.

Not to mention most of the people in the sling and investigation brigade, but at least they should be one of the best among the criminal police currently under investigation.

However, when Lu Chuan was analyzing the face of the suspect in the case of defrauding Sun Yuting just now, he did not make any progress for more than an hour, which shows the difficulty of image processing.

Although there is a reason why the computer is not powerful, but the current survey is also using this computer.

As a subordinate unit of the Criminal Investigation Detachment, the Graphic Investigation Brigade will definitely not disagree with Liu Guodong's request.

Wu Kaiyue is the captain of the graphic investigation brigade, and he and Liu Guodong are also old acquaintances.

"Old Liu, are you still here in person?"

"It's been a long time since I saw you, just come and have a look."

Liu Guodong turned around and introduced Lu Chuan: "This is Lu Chuan, who came to the survey office last year."

"Haha, no introduction, no introduction, first-class hero twice, Lu Chuan!"

Wu Kaiyue didn't live in the deep mountains and old forests. Lu Chuan's name in the Criminal Investigation Detachment was even louder than that of Qin Yong, the leader of the detachment.

"Hello Captain Wu."

Lu Chuan had met Wu Kaiyue before, but he had never dealt with him before, so he was not very familiar with him.

"Old Liu, just now you called and said you wanted to borrow a computer? What's the matter?"

The criminal investigation side has always had low requirements for electronic products such as computers. There must be something wrong with borrowing the computer this time.

"There is a portrait analysis. Xiaolu uses our computer to do it, and it always crashes."

Liu Guodong pointed to Wu Kaiyue's computer: "In terms of the computer used to make images overall, it must be the best and most professional computer here."

"For this matter, you can just send the image directly, let me help you."

"Haha, it's because you guys are very busy in the investigation and don't want to cause trouble for you."

"Other people must be busy. You old Liu will not say anything. No matter how busy I am, I will find someone to do it for you. Don't worry, I will let the number one expert in the brigade to do it."

"Chen Kun?"

"That's right, it's Chen Kun. Don't worry now. Chen Kun's level is among the top in the province. He specializes in surgery. We can't do spot surveys, but we specialize in map surveys!"

The Graphic Investigation Brigade, like the current survey office, is a relatively popular specialty under the Criminal Investigation Detachment.

It doesn't mean how much power they have, but that grassroots units have more opportunities to ask for help.

Liu Guodong didn't expect Wu Kaiyue to directly ask the number one expert of the Graphic Investigation Brigade to help.

If that's the case, will Lu Chuan still do it?
Liu Guodong glanced at Lu Chuan, which meant to ask for Lu Chuan's opinion.

Lu Chuan nodded slightly.

Chen Kun has also heard of him. He is a baby lump of the graphic investigation brigade, and he does not usually take action in cases.

Those who can make him take action are basically homicides.

The murder case that the Criminal Investigation Detachment solved some time ago involved surveillance videos that were all handled by Chen Kun, and they did provide a lot of clues.

But Lu Chuan was not sure whether the other party could handle it.

After all, this case is a major case in QZ City, and it must have been studied by the graphic investigation team there.

The results are obvious and there are no results.

However, the overall business level of the Haizhou Public Security Bureau is slightly higher than that of QZ City.

Perhaps the figure can be much higher here?
Analysis Room No. [-] of the Graphic Investigation Brigade.

Chen Kun, as No.1 in the graphic investigation brigade, has his own dedicated studio, and the computers he uses are of course top-notch.

"Old Chen, do you have time to look at this case?"

Chen Kun was watching the surveillance video in front of the computer when he was suddenly interrupted, feeling a little unhappy.

This is the shortcoming of a technical man, showing emotions and anger.

But Wu Kaiyue's voice was familiar to him, he suspended the work at hand and got up.

"Captain Wu, Director Liu."

Liu Guodong nodded and motioned for Lu Chuan to hand over the USB drive.

"Mr. Chen, hello, I'm Lu Chuan, who is currently surveying."

Chen Kun's eyes changed slightly. Although he didn't know Lu Chuan very well, he had heard of him.
