.
Shi Lei picked up the camera again and explained, "Using the crime scene reenactment, we try to compare the inherent dynamic characteristics of human behavior.
Everyone's movements may look similar, but in reality, there are huge differences.
Although we humans can't see these differences with our naked eyes, a computer can! "
Bai Qiang's eyes lit up. "Brother Shi, is what you said true?"
"Brother Bai, of course it's true!
This is a dynamic behavior capture program. I've already developed it. We can verify it later! "
Shi Lei turned around and said, "Uncle Zheng, quickly tell your men to learn the thief's movements and reenact the crime scene!"
The four members of the technical department started to learn with resentment towards Shi Lei.
Half an hour later, they used a stool as a prop to reenact the crime scene.
Shi Lei held the high-definition camera and started to film them.
On the computer screen, the dynamic behavior capture program captured the movements of the technical department's police officers and compared them with the 3D model animation in real time!
The real-time comparison rate of the four police officers was less than 30%. In other words, it was impossible for them to be the culprit.
"Brother Bai, go and bring Liu Long back. I want him to give it a try!" Shi Lei said confidently.
Another half an hour later, Liu Long was brought back to the police station and brought to the technical department. Shi Lei said, "Hello, Mr. Liu. I'm a special police technician. My name is Shi Lei!"
Liu Long wore a pair of glasses and had the unique aura of an intellectual. He said calmly, "I cooperated with your investigation yesterday. If you don't have evidence, please don't disturb my life and work!"
Shi Lei sneered in his heart. Liu Long's psychological quality was quite good. Shi Lei was now even more certain that Liu Long was the culprit!
"Mr. Liu, the police have obtained a new technology.
We just need to reenact the crime scene and confirm your suspicion.
Now, please take a look at the crime scene. This is the footage recorded by the secret camera. I hope you can learn the movements of the thief in this video and reenact it in front of us! "Shi Lei said calmly, but there was an undeniable force in his tone.
When Liu Long heard about the footage recorded by the secret camera, his pupils involuntarily shrank. Although he recovered quickly, Shi Lei still noticed it!
'Hmph!
As expected, it's you! "Shi Lei coldly looked at Liu Long and then moved aside to let Liu Long study.
"Mr. Liu, you have 15 minutes to study.
If you can't learn it, I'll take you to the interrogation room and let you stay there for twenty-four hours.
Don't talk to me about the law. I know the law better than you do. This is in accordance with the law! "Shi Lei directly blocked Liu Long's path of retreat.
Liu Long opened his mouth, but in the end, he didn't say anything. Looking at the images on the screen, his body stiffened as he started learning.
Fifteen minutes later, Bai Qiang and the others looked at Liu Long. They slowly lowered their bodies and reconstructed the crime scene.
This was his first time reenacting the crime scene. Liu Long's body movements were stiff, and he even deliberately made some unnecessary movements, which made Bai Qiang frown.
Shi Lei held the high-powered camera and recorded Liu Long's movements in real time with the 3D model animation.
No matter how out of line Liu Long's actions were, in the dynamic motion capture program's judgment, he had the same characteristics as the thief in the video!
For the first time, the matching rate reached 78%!
Bai Qiang looked at the data on the screen, and his eyebrows twitched. Shi Lei waved his hand and whispered, "Brother Bai, confirm it again!"
Bai Qiang nodded and shouted, "Liu Long, be careful. Let's do it again!"
This time, not only did Liu Long's actions not follow the rules, but they were even worse. However, the matching rate of the dynamic motion capture program reached 72% again!
Shi Lei snorted, "Mr. Liu Long, I'll give you one more chance. If you don't follow the rules, the interrogation room will treat you twenty-four hours a day!"
Liu Long's heart tightened, and his actions subconsciously became more standard. The matching rate of the dynamic motion capture program's matching rate reached 89%!
Bai Qiang couldn't hold it in anymore and shouted, "Arrest him!"
Liu Long was stunned. He didn't know what Bai Qiang meant.
Two members of the technical department immediately rushed up and subdued Liu Long. Liu Long shouted, "What are you doing?
You don't have any evidence! "
Bai Qiang pointed at the computer screen and said, "Now we have evidence!
Liu Long, you'd better behave yourself!
Take him to the interrogation room first, and then let the people from the interrogation department interrogate him properly! "
Liu Long saw that Bai Qiang was serious. He quickly said, "Wait!
I have an alibi! "
Shi Lei's eyes narrowed. He carefully looked at Liu Long and said, "What alibi do you have?
Why didn't you say it during the first investigation? "
Liu Long's face turned red. He whispered, "How could I have the nerve to say that kind of alibi!"
"What kind of alibi do you have? Hurry up and tell us. We'll investigate it immediately!" Bai Qiang questioned.
The two police officers from the technical department loosened their grip on Liu Long a little.
"In your police investigation, Jiang Li and I don't have an alibi, right?
Actually, we both have an alibi!
Regardless of whether it was the first theft or the second theft, both of us have sufficient alibis! "
Liu Long said excitedly, "Our alibi is at the Yayue Hotel. You can check the records of the Yayue Hotel.
During the two thefts, Jiang Li and I were at the Yayue Hotel. "
Bai Qiang was slightly startled. If that was the case, then Liu Long and Jiang Li's alibi would be established. Their suspicion would immediately be reduced by a lot.
Bai Qiang turned to look at Shi Lei and asked, "Brother Shi, what do we do now?"
Shi Lei looked at Liu Long with a silent sneer. "What can a mere hotel record prove? It can only prove that they were at the Yayue Hotel. It's not enough to prove that they were there all the time."
Bai Qiang thought for a moment and said, "Brother Shi, should we check the Yayue Hotel?"
"No!
The Yayue Hotel must have a hotel record. It's useless to check it!
Brother Bai, what's your police network account number?
Lend it to me! "Shi Lei said.
Bai Qiang hesitated. "Brother Shi, what are you going to do?"
"Check the social security monitoring system of the Social Security Monitoring Department and the road monitoring system of the Transportation Bureau.
I'm looking for something that interests me! "Shi Lei explained.
Bai Qiang was shocked. "You even know this!"
Shi Lei smiled. "Brother Bai, do you think this is a secret?
Give me your account number quickly. I don't know if the records are still there after so many days! "
Bai Qiang logged into the police network from the server. Shi Lei was familiar with the police network and found the program of the social security monitoring system. Then, he searched for the location of the public security camera near the Yayue Hotel.
There was a public security camera right behind the Yayue Hotel. Shi Lei immediately checked the camera's recording of October 30th and November 8th.
Shi Lei looked up at Liu Long and asked, "When did you get a room at the Yayue Hotel?"
Liu Long looked at Shi Lei, his eyes somewhat evasive. Then, he said, "At eight o 'clock in the evening."
"The time of the theft was 11: 20 at night. It takes about fifty minutes to get from the Yayue Hotel to the City Museum. In other words, you have to leave the Yayue Hotel before 10: 30!"
Shi Lei opened the public security camera's recording and chose the time of October 30th at eight o 'clock in the evening. Then, he played the video in fast forward mode.
Liu Long's forehead was covered in sweat. His breathing was a little rough, and he tried his best to calm himself down.
When the video's recording reached 10: 10, a figure peeked out from the window on the second floor. Then, the figure threw down something like a rope ladder and climbed down from the second floor!
Shi Lei paused the video and looked at Liu Long. "What do you have to say now?"
Liu Long said stubbornly, "What can this prove? The video is so dark and blurry. How can it prove that it's me?"
"I won't give up until I reach the Yellow River!"
Shi Lei picked up the HD camera and pointed it at the screen. He began to capture the person's walking posture in the video. At the same time, he used the Unreal Graphics Processing Software to create a 3D model animation.
"Use your normal pace. Take two steps and see!"
Liu Long took two steps unnaturally. The HD camera recorded it, and the dynamic behavior capture program analyzed the dynamic characteristics of the behavior and compared the similarity rate.
The dynamic characteristics of simple behavior like walking were very obvious. The dynamic characteristics of Liu Long and the man in the video were as high as 95%!
Bai Qiang smiled. "Liu Long, you still won't admit it?"
Liu Long said stubbornly, "You don't have direct evidence!"
Shi Lei suddenly asked, "What's the degree of your spectacles?"
"This is a private question. I refuse to answer!" Liu Long refused to cooperate.
"You have to answer this question. Otherwise, the evidence we have now is enough to detain you in the police station and assist in the investigation!" Shi Lei said calmly. There was no threat in his tone.
Liu Long's expression changed. In the end, he said, "Both of my eyes are 700 degrees!"
"Hehe, high myopia. That's good news!"
Shi Lei picked up his phone and dialed 114. Then, he asked, "Hello, I would like to ask if there are any optician shops around the city museum?"
At the same time, Shi Lei searched for information about the optician shops around the city museum on the search engine.
The 114 customer service reported all the registered optician shops around the city museum to Shi Lei. Shi Lei recorded their phone numbers.
Bai Qiang was puzzled. He asked curiously, "Brother Shi, why are you asking about the optician shops?"
Liu Long's expression turned even uglier.
