The power of the hk154 behavioral motion capture program
Shi Lei picked up the camera again and explained: "Using crime scene reenactments, we try to compare the inherent dynamic characteristics of human behavior. Everyone's actions may look similar, but in fact they are very different. Although we
The human eye cannot tell this difference, but a computer can compare it!"
Bai Qiang's eyes lit up, "Brother Shi, are you telling the truth?"
"Brother Bai, of course it's true! I have developed this program called behavioral dynamic capture. I can verify it in a while!" Shi Lei turned around and said: "Uncle Zheng, hurry up and tell your men to learn it.
The actions of the thief, and then the crime scene was recreated!”
The four technicians in the technical department began to study with resentment against Shi Lei. Half an hour later, they used a stool as a prop to recreate the crime scene. Shi Lei held a high-definition camera and filmed them.
.
On the computer screen, the behavioral dynamic capture program captures the movements of the technical police officers recreating the crime scene, and then compares them with the three-dimensional model animation in real time!
The real-time comparison rate of the four police officers is less than 30% at best, which means it is completely impossible to be them.
"Brother Bai, go and bring that Liu Long back now, I want him to give it a try!" Shi Lei said with some confidence.
More than half an hour later, Liu Long was taken back to the police station and brought to the technical department. Shi Lei said: "Hello, Mr. Liu, I am a special technician of the police, and my name is Shi Lei!"
Liu Long wore a pair of glasses and had a unique aura of an intellectual. He said calmly: "I just cooperated with you in an investigation yesterday. If you don't have evidence, please don't harass my life and work!"
Shi Lei sneered in his heart, Liu Long's psychological quality was quite good, and Shi Lei was even more sure that this was Liu Long at this moment!
"Mr. Liu, our police have obtained a brand-new technology. We just need to recreate the crime scene and then confirm your suspicion. Now please take a look. This is the crime scene and the footage captured by the secret camera. I hope you can
Learn the actions of the thief in this video, and then replay it in front of us!" Shi Lei's tone was calm, but there was an undoubted compulsion.
When Liu Long heard the footage captured by the secret camera, his pupils involuntarily shrank slightly. Although he recovered quickly, Shi Lei still discovered it!
‘Huh! It’s you indeed!’ Shi Lei looked at Liu Long coldly, then moved away to let Liu Long study.
"Mr. Liu, you have fifteen minutes to study. If you can't learn, I will take you to the interrogation room and let you stay in the interrogation room for twenty-four hours. Don't mention the law to me, I am more knowledgeable than you.
You know the law, this is in compliance with the law!" Shi Lei directly blocked Liu Long's retreat.
Liu Long opened his mouth, but finally said nothing. Looking at the picture on the screen, his limbs stiffened and he began to study.
Fifteen minutes later, Bai Qiang and others looked at Liu Long, slowly lowered their bodies, and then reenacted the crime scene. When reenacting the crime scene for the first time, Liu Long's body movements were stiff, and he even deliberately made some unnecessary movements.
, which made Bai Qiang frown.
Shi Lei is holding a high-power camera, and Liu Long's movements are compared with the 3D model animation in real time. Even if Liu Long's movements are outrageous, in the judgment of the behavioral dynamic capture program, he and the thief in the video have the same characteristics.
Action features!
For the first comparison of behavioral dynamic characteristics, the coincidence rate reached 78!
Bai Qiang looked at the data on the computer, his brows twitched, but Shi Lei waved his hand and whispered: "Brother Bai, confirm again!"
Bai Qiang nodded and shouted: "Liu Long, please behave properly and try again!"
This time, Liu Long's movements were not only unstandardized, but even worse. However, the compliance rate of the behavioral dynamic characteristics comparison of the behavioral dynamic capture program once again reached 72!
Shi Lei snorted coldly, "Mr. Liu Long, I'll give you another chance. If you don't do it according to standards, you will be treated in the interrogation room 24 hours a day!"
Liu Long's heart tightened, and his subconscious movements became more standardized. The behavioral dynamic characteristics comparison rate of the behavioral dynamic capture program suddenly reached 89!
Bai Qiang couldn't bear it anymore and yelled: "Catch him!"
Liu Long was stunned and didn't understand what Bai Qiang meant. Two technicians from the technical department immediately rushed forward and subdued Liu Long with his backhand. Liu Long shouted: "What are you doing? You have no evidence that it's me!"
Bai Qiang pointed at the computer screen and said: "Now we have it! Liu Long, please be more honest with me! Put him into the interrogation room first, and then let the people from the interrogation department interrogate him properly!"
When Liu Long saw Bai Qiang acting serious, he quickly said: "Wait! I have alibi!"
Shi Lei's eyes narrowed, and he looked at Liu Long carefully, and then said: "What alibi do you have? Why didn't you tell it during the first investigation?"
Liu Long's face turned red and he whispered: "How can I have the nerve to say that kind of alibi!"
"What kind of alibi is it? Tell me quickly. We will check it immediately!" Bai Qiang asked.
The two policemen from the technical section released Liu Long a little.
"During your police investigation, neither Jiang Li nor I had an alibi, right? In fact, both of us have alibi! Whether it was the first theft or the second theft, the two of us have very good alibi.
Enough!" Liu Long said with some excitement: "Our alibi is in Yayue Hotel. You can check the records of Yayue Hotel. Jiang Li and I were at Yayue Hotel during the two thefts."
Bai Qiang was slightly startled. If this was the case, then the alibi of Liu Long and Jiang Li would be established, and their suspicion would be greatly reduced immediately. Bai Qiang turned to look at Shi Lei and asked, "Shi Lei
Brother, what should we do now?"
Shi Lei looked at Liu Long with a silent sneer, "What can a mere room opening record prove? It can only prove that they have booked a room in Yayue Hotel, but it is not enough to prove that they have always been in Yayue Hotel."
Bai Qiang thought for a while and said: "Brother Shi, should we go to check Yayue Hotel?"
"No need! Yayue Hotel will definitely have their room opening records, and checking it will be useless! Brother Bai, what is your police network account number? Lend it to me!" Shi Lei said.
Bai Qiang hesitated and said: "Brother Shi, what are you going to do?"
"Check the public safety monitoring system of the Social Security Supervision Section and the road monitoring system of the Transportation Bureau. Look for something that interests me!" Shi Lei explained.
Bai Qiang was shocked: "You even know this!"
Shi Lei chuckled: "Brother Bai, do you think these are secrets? Give me your account quickly. I wonder if those records are still there after so many days!"
From the server, Bai Qiang logged into the police network. Shi Lei was familiar with the police network and found the program of the social public security surveillance system, and then searched for the location of the public security cameras near Yayue Hotel.
There happened to be a public security camera directly behind the Yayue Hotel. Shi Lei immediately checked the camera's recordings of October 30 and November 8.
Shi Lei looked up at Liu Long and asked, "When did you open a room at Yayue Hotel?"
Liu Long looked at Shi Lei, his eyes evasive, and then said: "Eight o'clock in the evening."
"The time of the theft was 11:20 pm. It takes about fifty minutes to get from Yayue Hotel to the Municipal Museum. In other words, you must leave Yayue Hotel before 10:30!" Shi Lei opened the public security button.
The recording of the camera was directly selected from the time point of eight o'clock in the evening on October 30, and then played back 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 down.
When the time node recorded in the video reached ten past ten, a figure leaned out of the second-floor window, then dropped something like a rope ladder and climbed down from the second floor!
Shi Lei clicked pause, looked at Liu Long and said, "What else do you have to say now?"
Liu Long said forcefully: "What can this prove? The picture is so dark and blurry, how can it prove that it is me!"
"Don't give up until you reach the Yellow River!" Shi Lei picked up the high-definition camera, pointed it at the screen, and began to capture the walking posture of the person in the screen. At the same time, he used Unreal graphics processing software to build a 3D model animation again. "Use your normal
Take a few steps and take a look!"
Liu Long took two steps unnaturally, and the high-definition camera recorded it. The behavioral dynamic capture program analyzed the dynamic characteristics of the behavior and compared the similarity and coincidence rate. The dynamic characteristics of a simple behavior such as walking are very obvious. Liu Long and the man in the video,
The compliance rate of behavioral dynamic characteristics is as high as 95!
A smile appeared on Bai Qiang's face, "Liu Long, you still don't admit it?"
Liu Long said stubbornly: "You have no direct evidence!"
Shi Lei suddenly asked: "What's the strength of your glasses?"
"This is a privacy question, I refuse to answer!" Liu Long replied uncooperatively.
"You must answer this question, otherwise the current evidence is enough to detain you at the police station and help cooperate with the investigation!" Shi Lei's tone was calm, without any threat.
Liu Long's expression changed, and he finally said: "Both eyes are 700 degrees!"
"Haha, you're highly myopic, that's really good news!" Shi Lei directly picked up his mobile phone, dialed 114, and then asked: "Hello, I would like to ask, what optical shops are there around the city museum?"
While asking, Shi Lei searched for news about optical shops around the city museum on the search engine.
The 114 customer service phone number reported all the registered optical shops around the city museum for Shi Lei, and Shi Lei recorded their phone numbers.
Bai Qiang was puzzled and asked curiously: "Brother Shi, why are you asking the optical shop?"
Liu Long's face turned even uglier!
