Lu Chuan knew that there were computers on the market that specialized in image processing.
These computers have very high requirements for 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 they are 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 yourself according to the needs, and there are also ready-made machines, but in most cases they are not as good as professionally assembled ones.
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 detachment obviously didn't think so.
"Master, can you go to the picture detective's place and borrow their computer?"
Under the Haizhou City Criminal Investigation Detachment, there is a map investigation brigade, which was only established in the past ten years.
Nowadays, the investigation of criminal cases relies more and more on the discovery of surveillance videos.
Some crimes are directly recorded by surrounding surveillance cameras.
So the Picture Scout Brigade came into being.
Surveillance cameras on the market have different brands, different qualities, and different installation times. The quality of video shooting can be described as vastly different.
The standards for high-definition are different between the high-definition cameras installed ten years ago and the high-definition cameras installed now.
Some cameras shoot well during the day, but can only capture blurry figures at night.
Some cameras are obviously high-definition cameras, but due to neglect of maintenance, the front of the lens is stained 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 clarity levels.
Most of these videos cannot directly identify the suspect's appearance.
It is necessary to use technical means to process the video information. This is the job of the picture detective team.
And judging from all the cases Lu Chuan has come into contact with since joining the police, basically every case involves the investigation of surveillance videos. .
Because some cases take too long, the amount of video to be investigated is quite large, which may last ten to twenty days, or even a month, and the maximum can be traced to three months or even longer.
There are so many videos for one case, ten cases, one hundred cases.
The amount of data can be described as astronomical.
Although the Haizhou City Public Security Bureau’s Map Investigation Brigade has a large number of personnel, with 138 members, plus auxiliary police officers and some contract workers, the entire Map Investigation Brigade has more than 300 people.
But even with so many people, it was still very busy.
This can also explain from the side the case in which Sun Yuting was deceived in QZ City. Although the amount involved was large, the suspect's true identity has not been determined through picture recognition.
It’s not that it’s unimportant, it’s just that I’m really too busy.
Also... neither is technology.
Although Lu Chuan has not acquired image processing skills in the system, his image processing capabilities in advanced fingerprint skill identification and analysis are already very powerful.
Not to mention most of the people in the investigation team, but at least he should be one of the best among the current detectives.
However, when Lu Chuan just analyzed the faces of the suspects in the Sun Yuting fraud case, he did not make any progress for more than an hour, which shows the difficulty of image processing.
Although there are reasons why computers are not powerful, this is the computer used in current surveys.
As a subordinate unit of the Criminal Investigation Detachment, the Visual Investigation Brigade would definitely not disagree with Liu Guodong's request.
Wu Kaiyue is the captain of the Scout Brigade and is an old acquaintance of Liu Guodong.
"Old Liu, are you here in person?"
"I haven't seen you for a long time, so I just came over to take a look."
Liu Guodong turned around and introduced Lu Chuan: "This is Lu Chuan, who came to the current survey office last year."
"Haha, no introduction, no introduction, twice the first-class meritorious hero, Lu Chuan!"
Wu Kaiyue doesn’t live in Shenzhen
Shan Laolin, Lu Chuan's reputation in the criminal investigation detachment is more famous than that of Qin Yong, the detachment leader.
"Hello, Captain Wu."
Lu Chuan had met Wu Kaiyue, but he had never interacted with him before and was not particularly familiar with him.
"Old Liu, you just called and said you wanted to borrow a computer? What's going on?"
The criminal investigation side has always not had high requirements for electronic supplies such as computers. There must be something wrong with borrowing a computer this time.
"There is a portrait analysis. Xiao Lu uses our computer to do it, but it always crashes."
Liu Guodong pointed to Wu Kaiyue's computer: "Looking at the overall situation of computers used for image processing, yours must be the best and most professional."
"For this matter, you can just send the image over. I'll do it for you."
"Haha, isn't this because you guys are very busy, so I don't want to cause any trouble to you."
"Everyone else is definitely busy, but you, Liu Lai, don't say anything. No matter how busy you are, I will find someone to do it for you. Don't worry, I will let the top expert of the brigade to do it."
"Chen Kun?"
"Yes, it's Chen Kun. Don't worry now. Chen Kun's level is among the best in the province. He specializes in the field. We can't do spot surveys, but we specialize in picture reconnaissance!"
The Map Investigation Brigade, like the Investigation Office, is a popular major under the Criminal Investigation Detachment.
It’s not that they have much power, but that grassroots units have more opportunities to ask for help.
Liu Guodong did not expect that Wu Kaiyue would directly ask the top expert of the Picture Scout Team for help.
If this is the case, should Lu Chuan still do it?
Liu Guodong glanced at Lu Chuan, which meant to ask for Lu Chuan's opinion.
Lu Chuan nodded slightly.
He has also heard of Chen Kun. He is the treasure of the Detective Team and usually does not deal with cases.
The things that can make him take action are basically murder cases.
The surveillance video involved in the murder case detected by the Criminal Investigation Detachment some time ago was all produced by Chen Kun, and it 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 one in QZ City, and it must have been studied by the detective team there.
The result is obvious, there is no result.
However, the overall business level of the Haizhou City Public Security Bureau is slightly higher than that of QZ City.
Maybe the picture scout side can be much higher?
Analysis Room No. 1 of the Pictorial Reconnaissance Brigade.
As the first person in the picture scout team, Chen Kun has his own dedicated studio and of course uses the most top-notch computers.
"Old Chen, do you have time to take a look at this case?"
Chen Kun was browsing surveillance videos in front of the computer when he was suddenly interrupted, which made him a little unhappy.
This is the shortcoming of technical men, they are moody and angry.
But Wu Kaiyue's voice was familiar to him, so he paused the work at hand and stood up.
"Team Wu, Director Liu."
Liu Guodong nodded and motioned to Lu Chuan to hand over the USB flash drive.
"Hello, Teacher Chen, I am Lu Chuan from the current survey."
Chen Kun's eyes changed slightly. Although he didn't know Lu Chuan very well, he had heard of his name.
