The current survey office.
Lao Bai handed Lu Chuan a cup of tea.
"Don't work so hard, take a rest first, smoke a cigarette and get some fresh air."
Wu Kaiyue sent a total of 56 pictures.
In one morning, Lu Chuan had already produced almost half of the quantity.
The clarity of most of the pictures processed by Lu Chuan has been greatly improved, and they can basically be used as blacklist comparison standard pictures.
However, because the blurriness of some photos was too high, after Lu Chuan applied the data conversion method, the photos were still not clear enough.
This kind of situation is difficult for a clever woman to make a meal without rice, and Lu Chuan has no good solution for the time being.
Arranged into separate folders, Lu Chuan put together the particularly good pictures that he had not processed.
Of course, Lu Chuan hadn't seen any of the cases these photos involved.
Anyway, most of them were large-scale fraud cases, and there were also some previous criminal cases where the camera captured side faces or unclear frontal portraits.
Looking at the nearly thirty photos left, Lu Chuan took the tea handed over by Lao Bai.
"Well, let's take a rest. They didn't say when it needs to be finished."
Lu Chuan was a little surprised by the computer configuration sent by the scout team. It was indeed good.
It far exceeded Lu Chuan's expectations for an office computer.
The work of the current survey office is not too busy in most cases.
As long as there is no murder, we are basically in a state where we can fish whenever we want.
But if there is a real murder, it is normal to spin around.
In Lao Bai's words, this is not good for your health.
If you live an irregular life, you will die early.
Lu Chuan didn't really want to eat in the canteen at noon.
To be honest, the food in the canteen of the Criminal Investigation Detachment is pretty good.
There are three meals, breakfast, lunch and dinner, with the most sumptuous lunch being five dishes, one soup and two cold dishes.
But that’s not the case at night. Dinner is usually the leftovers from lunch.
There was no such thing as late-night snacks before. The criminal investigation detachment’s late-night snack was instant noodles.
Instant noodles of various flavors such as braised in brown sauce, soup stock, chicken stewed with mushrooms, and vine pepper.
Lu Chuan didn't catch up with the good times. He heard Lao Bai say that when he had the most instant noodles, he could fill a wall.
There is no need for it now. Under special circumstances, that is, when major cases occur, the canteen is always manned.
Although the chef on duty cannot make a few dishes or soups due to lack of manpower, at least soaking instant noodles can turn into boiling instant noodles.
After calling Liu Guodong and the others, Lu Chuan drove his Cayenne and ran to eat hot pot.
However, the weather in April is unpredictable.
It was still sunny in the morning, but cloudy and rainy in the afternoon.
The current survey office.
Lu Chuan was scrolling through photos in front of the computer, and scenes of data continued to flow on the screen.
After a morning of familiarity, Lu Chuan became more and more comfortable, and his speed in processing pictures increased a lot.
Lu Chuan also tried to write some plug-in software.
For example, for low-pixel photos, images and data can be converted directly and data can be enhanced automatically.
The result is no.
Because the degree of blur in each photo is different, the blurred parts are different.
The process of data enhancement requires Lu Chuan to make human judgments and then choose different methods for processing.
Different methods involve different mathematical transformation formulas.
It is common for multiple methods to be used interchangeably.
Sometimes it is even necessary to use some uncommon methods such as Laplace transform and wavelet transform to process some independent data.
The processing process of each picture is relatively complicated, and it is very difficult to use a plug-in to solve all problems.
It seems that this method cannot be widely promoted for the time being.
Lu Chuan looked at the boring computer screen
During the data collection, Yang Sen stood in front of the window with some melancholy.
The rain came down harder and harder, soon blurring the view.
"What are you thinking about?"
Lao Bai poked Yang Sen in the arm.
"It's nothing. It's just that it's raining so heavily outside. It wouldn't be easy to handle a case if it happens."
Um?
After Yang Sen finished speaking, Lao Bai's expression changed.
"Crow's Mouth, what case are you talking about, bah bah bah!"
People who work in the police profession should be staunch materialists, but sometimes things can be so evil.
When you don't make a proposal, nothing happens.
But as long as it is mentioned casually, the case will come.
Yang Sen obviously realized what he had just said.
Snapped.
He slapped himself in the mouth: "Bah, bah..."
boom!
As a result, before the last word "bah" could be said, the office door was knocked open.
It's Liu Guodong.
Lao Bai and Yang Sen turned their necks stiffly, looked at Liu Guodong with a hurried expression, looked at each other, and said in unison: "Is there a case?"
Liu Guodong was slightly startled. He had just received the notice. Who told them?
"How do you know?"
Yang Sen now wants to slap himself again.
"What the hell is this?"
Lao Bai shook his head helplessly: "Is the case big?"
Liu Guodong nodded: "A body was found on the bank of Bailan River. We have to go and have a look."
"Bai Lanhe?"
Yang Sen's face looked even worse.
Why did he think of the case just now when he was looking at the heavy rain outside the window.
This is because if a case occurs on a rainy day, it will be very difficult to preserve a lot of evidence.
Rain will take away most of the traces left by the murderer, and may even bring things that do not belong to the scene.
Three years ago, a murder occurred in Tianzhou City, which was discovered after heavy rain.
The body was found lying in a roadside ditch.
After the heavy rain, all traces of the scene were completely wiped away, except for a handkerchief in the deceased's pocket.
In this day and age, who else would use a handkerchief?
Therefore, the police quickly used a handkerchief to locate a 60-year-old man in a nearby village during the visit.
Because the crime scene was washed very clean by the heavy rain, all traces left by the murderer were erased. Only a handkerchief that once belonged to the old man appeared in the pocket of the deceased.
So, logically speaking, the old man is very likely to be the murderer.
In addition, the old man and the deceased knew each other, they were neighbors, and they had just had a quarrel over the courtyard wall.
In this way, the old man naturally became the biggest suspect of the murderer.
The old man lived alone, and no one could prove whether he was at home when the deceased died.
At that time, the police had already taken coercive measures against the elderly.
After all, judging from the scene, how could a handkerchief used by an old man appear in the pocket of the deceased for no reason?
But in fact, the old man's handkerchief was lost three days ago.
It was the heavy rain that washed away the handkerchief that was originally thrown in the gutter and washed it into the pocket of the deceased.
However, no one believed the old man when he said that he had lost his handkerchief.
If the murder weapon hadn't been found, the case would have been closed.
Later, the Tianzhou City Criminal Investigation Detachment found a little blood on the rice bag at the deceased's home.
Then the murder weapon was found in the rice bag, and by collecting fingerprints on it, it was confirmed that the murderer was the deceased's wife.
Otherwise, the old man back then might really have been wronged.
