The Power of the Hk154 Behavioral Motion Capture Program

Shi Lei picked up the camera again and explained: "Using the crime scene to recreate, try to compare the inherent dynamic characteristics of human behavior. The movements of each person may look similar, but in fact they are very different. Although we human beings The naked eye can tell the difference, but the 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 dynamic behavior capture, and I can verify it in a while!" Shi Lei turned his head and said, "Uncle Zheng, hurry up and tell your subordinates to learn it. The action of the thief, and then the crime scene is recreated!"

The members of the four technical departments began to learn with resentment towards Shi Lei. Half an hour later, they used a stool as a prop to recreate the scene of the crime. Shi Lei held a high-definition camera and filmed them.

On the computer screen, the behavioral motion capture program captures the action of the police in the technical section recreating the crime scene, and then compares it with the animation of the 3D model in real time! [

The real-time comparison coincidence rate of the four police officers is less than 30% at the highest, which means that it is completely impossible for them.

"Brother Bai, go and bring back that Liu Long now, I want him to try it!" Shi Lei said with some confidence.

More than half an hour later, Liu Long was taken back to the police station and to the technical department. Shi Lei said, "Hello, Mr. Liu, I'm a special police technician, my name is Shi Lei!"

Liu Long wears a pair of glasses and has a unique atmosphere of intellectuals. He said indifferently: "I only cooperated with you to investigate once yesterday. If you have no evidence, please don't harass my life and work!"

Shi Lei sneered in his heart, Liu Long's psychological quality is quite good, Shi Lei is more sure this is Liu Long at this moment!

"Mr. Liu, our police have got a brand new technology. We just need to recreate the crime scene and then determine your suspicion. Now please take a look. This is the scene of the crime, captured by a secret camera, I hope you can Study and learn the movements of the thief in this video, and then reproduce it in front of us!" Shi Lei's tone was flat, but there was an unquestionable compulsion.

When Liu Long heard the secret camera, his pupils involuntarily shrank slightly. Although he recovered quickly, Shi Lei still found it!

'Humph! Sure enough, it's you! ' Shi Lei looked at Liu Long coldly, then moved aside to let Liu Long learn.

"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 24 hours. Don't talk to me about the law, I'm better than you. Know the law, this is in line with the law!" Shi Lei directly blocked Liu Long's retreat.

Liu Long opened his mouth, but in the end he didn't speak. 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 recreated the crime scene. For the first time to reproduce 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 is holding a high-powered camera, and Liu Long's movements and the animation of the 3D model are being compared and recorded in real time. Even if Liu Long's actions are out of line again, in the determination of the behavioral dynamic capture program, he and the thief in the video have the same action characteristics!

The first comparison of behavioral dynamic features, 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 loudly: "Liu Long, be more standardized, and do it all over again!"

This time, Liu Long's actions were not only not standardized, but even worse, but the coincidence rate of the behavior dynamic feature comparison of the behavior dynamic capture program once again reached the level of 72!

Shi Lei snorted coldly, "Mr. Liu Long, I'll give you one more chance. If you don't behave properly, the interrogation room will treat you 24 hours a day!"

Liu Long's heart tightened, and the subconscious action standards were a little bit better. The comparison rate of the behavioral dynamic characteristics of the behavioral dynamic capture program suddenly reached 89!

Bai Qiang couldn't bear it any longer, and shouted: "Arrest him!" [

Liu Long was stunned, not understanding what Bai Qiang meant. The two technical staff members rushed up to subdue 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, "There is now! Liu Long, please be honest with me! First put him in the interrogation room, and then let the people of the interrogation department interrogate him well!"

Seeing that Bai Qiang was really moving, Liu Long said quickly, "Wait! I have alibi!"

Shi Lei's eyes narrowed, watching Liu Long carefully, and then said: "What evidence do you have of alibi? Why didn't you say it during the first investigation?"

Liu Long's face flushed, and he whispered, "How could I be so embarrassed to say that kind of alibi!"

"What is the evidence of alibi, hurry up and say it, we will check it right away!" Bai Qiang asked.

The two police officers from the technical department let go of Liu Long a little.

"During your police investigation, Jiang Li and I didn't have an alibi? In fact, both of us have alibi! Whether it's the first theft or the second, our alibi is very strong. Sufficient!" Liu Long said a little excitedly: "Our alibi, at the Yayue Hotel, you can investigate the records of the Yayue Hotel. Jiang Li and I were at the Yayue Hotel during the two thefts."

Bai Qiang was slightly taken aback. If this is the case, then Liu Long and Jiang Li's alibi will be established, and their suspicions will be greatly reduced immediately. Bai Qiang turned to look at Shi Lei and asked, "Brother Shi, what should I do now?"

Shi Leisheng looked at Liu Long with a sneer, "What can be proved by the mere opening records? It can only prove that they once opened a room in the Yayue Hotel, but it is not enough to prove that they have always been in the Yayue Hotel."

Bai Qiang thought for a while and said, "Brother Shi, shall we go to Chacha Yayue Hotel?"

"No! Yayue Hotel will definitely have their room opening records. If you check it, it's a white check! Brother Bai, what is your police online account? Lend it to me!" Shi Lei said.

Bai Qiang hesitated: "Brother Shi, what are you going to do?"

"Check out the social security surveillance system of the Social Security Supervision Department, and the road surveillance system of the Transportation Bureau. Find something that interests me!" Shi Lei explained.

Bai Qiang was shocked: "You even know this!"

Shi Lei smiled: "Brother Bai, do you think these are secrets? Hurry up and give me your account number, I don't know if so many days have passed, those records are still there!"

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 looked for the location of the public security camera near the Yayue Hotel.

Right behind the Yayue Hotel, there happened to be a public security camera. Shi Lei immediately checked the camera's recordings on October 30 and November 8.

Shi Lei looked up at Liu Long and asked, "When did you open a room in the Yayue Hotel?"

Liu Long looked at Shi Lei, his eyes dodged a little, and then said, "Eight o'clock in the evening."

"The time of theft is 11:20 pm. It takes about 50 minutes to get from the Yayue Hotel to the Municipal Museum. That is to say, you must leave the Yayue Hotel before 10:30!" Shi Lei opened the public security The recording of the camera directly selected the time node of 8 o'clock in the evening on October 30, and then played it in a fast-forward manner.

Liu Long's forehead was sweating, and his breathing was a little rough, trying his best to calm himself down. [

When the time point of the video recording reached 10:10, a figure leaned out from the door on the second floor, then dropped something similar to a rope ladder, and climbed down from the second floor!

Shi Lei paused, looked at Liu Long and said, "What else do you have to say now?"

Liu Long said firmly: "What can this prove? The picture is so dark and blurry, how can it prove that it is me!"

"Don't give up until the Yellow River!" Shi Lei picked up the high-definition camera, pointed at the screen, and began to capture the walking posture of the person in the picture. At the same time, he used the Unreal graphics processing software to build a three-dimensional model animation again. "Using your normal pace, take two steps to see!"

Liu Long took two steps unnaturally. The high-definition camera recorded it, and the behavioral dynamic capture program analyzed the behavioral dynamic characteristics and compared the similarity coincidence rate. The simple behavioral dynamic characteristics of walking are very obvious. Liu Long and the man in the video have a behavioral dynamic characteristic coincidence rate of 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, "How many degrees are your glasses?"

"This is a fucking question, I refuse to answer it!" Liu Long answered uncooperatively.

"You must answer this question, otherwise the current evidence is enough to detain you at the police station and assist in the investigation!" Shi Lei's tone was flat, without the slightest threat.

Liu Long's face changed, and finally said: "Both eyes are seven hundred degrees!"

"Hehe, high myopia, that's really good news!" Shi Lei picked up his mobile phone, dialed 114, and asked, "Hello, I would like to ask, which optical shops are around the city museum?"

While inquiring, Shi Lei was looking for news about the optical shops around the city museum on the search engine.

114 telephone customer service reported all the registered optical shops around the city museum for Shi Lei, and Shi Lei recorded their phone calls.

Bai Qiang was puzzled and asked curiously, "Brother Shi, what are you asking about the optical shop?"

Liu Long's face was even more ugly!
