HK154 behavior dynamic capture program's powerful

  .

  Shi Ke picked up the camera again and explained, "Using crime scene reconstruction to try to compare the inherent behavioral dynamics of humans. Every person's movements may look similar at first glance, but in reality, there are big differences. Although our human eyes can't distinguish these differences, computers can!"

  Bai Qiang's eyes lit up, "Shi, little brother, is what you're saying true?"

  "Old Bai, of course it's true! This program called motion capture, I've already developed it, and we can verify it in a moment!" Shi Lei turned his head and said: "Uncle Zheng, hurry up and instruct your subordinates to learn the thief's movements, then recreate the crime scene!"

  Four technical department staff members, with a grudge against Shi Ke, started learning. Half an hour later, they used a stool as a prop to recreate the crime scene. Shi Ke hugged a high-definition camera and began filming them.

  On the computer screen, motion capture software captures the movements of forensic scientists reenacting a crime scene and compares them in real-time with 3D model animations!

  The real-time matching rate of the four police officers was less than 30%, which means it's completely impossible that it was them.

  "White-haired old man, you go bring that Liu Long back now, I want him to give it a try!" Shi Lei said with some confidence.

  Another half hour passed, and Liu Long was taken back to the police station, brought to the technical department. Shi Ke spoke up: "Mr. Liu, nice to meet you, I'm a special technical personnel of the police, my name is Shi Ke!"

  Liu Long, wearing a pair of glasses and exuding an air of intellectualism, said calmly: "I just cooperated with your investigation yesterday. If you don't have any evidence, please don't disturb my life and work!"

  Shi Ke sneered inwardly, Liu Long's mental quality was quite impressive, and Shi Ke was even more certain that this was indeed the real Liu Long!

  "Mr. Liu, we've got a new technology in the police department. All we need to do is recreate the crime scene and identify your suspect. Now please take a look at this, it's the footage from the secret camera at the crime scene. We hope you can study the thief's movements in this video and then reenact them for us!" Shi Lei's tone was calm but had an unmistakable air of compulsion.

  Liu Long heard the sound of a hidden camera, and when he saw the footage, his pupils involuntarily contracted slightly. Although he quickly recovered, Shi Lei still noticed!

  "Hmph! I knew it was you!" Shi Lei coldly looked at Liu Long, then stepped aside to let him learn.

  "Mr. Liu, you have fifteen minutes to learn your lesson. If you don't, I'll take you to the interrogation room and let you stay there for twenty-four hours. Don't mention law to me, I know more about it than you do, this is all within the bounds of the law!" Shi Lei directly cut off Liu Long's retreat.

  Liu Long opened his mouth, but ultimately didn't speak, and stared at the screen, his limbs stiffening as he began to study.

  Fifteen minutes later, Bai Qiang and others looked at Liu Long, slowly lowered their bodies, and then reappeared at the crime scene. The first time they reappeared at the crime scene, Liu Long's body movements were stiff, and he even made some unnecessary movements on purpose, which made Bai Qiang frown.

  Shi Ke held a high-definition camera, Liu Long's movements were compared with 3D model animations in real-time. Even if Liu Long's actions went beyond the norm, under the judgment of the motion capture program, he and the thief on the screen had the same action characteristics!

  The first behavioral dynamic feature comparison achieved a compliance rate of 78%!

  Bai Qiang looked at the data on his computer and his eyebrows jumped. Shi Lei waved his hand and whispered, "Bai, confirm it again!"

  Bai Qiang nodded and shouted: "Liu Long, standardize your movements, try again!"

  This time, Liu Long's actions not only failed to standardize, but became even worse, with the behavior dynamic capture program's behavioral dynamic characteristics comparison conformity rate reaching 72% again!

  Shi Ke let out a cold snort, "Mr. Liu Long, I'll give you one more chance. If you don't do it properly, you'll be treated to 24 hours in the interrogation room!"

  Liu Long's heart tightened, and his subconscious actions became more standardized. The behavioral dynamics capture program's behavioral dynamic characteristics comparison conformity rate suddenly reached 89%!

  Bai Qiang could no longer hold back, and he loudly shouted: "Take him away!"

  Liu Long was stunned and didn't understand what Bai Qiang meant. Two technical department staff members immediately rushed up and pinned Liu Long's hands behind his back, and Liu Long shouted: "What are you doing? You have no evidence that it was me!"

  Bai Qiang pointed at the computer screen and said, "Now we have it! Liu Long, you'd better be honest with me! First, take him to the interrogation room, then let the interrogation team question him thoroughly!"

  Liu Long saw that Bai Qiang was about to get serious, so he hastily said: "Wait! I have an alibi!"

  Shi Ke's eyes narrowed, gazing intently at Liu Long, then said: "What alibi do you have? Why didn't you mention it during the first investigation?"

  Liu Long's face turned bright red as he said in a low voice: "How can I bear to mention that kind of alibi?"

  "What is this absence of evidence? Speak up quickly, we will go and verify it immediately!" Bai Qiang asked.

  Two technical officers slightly loosened Liu Long's restraints.

  "In your police investigation, neither Jiang Li nor I have an alibi, right? Actually, both of us have a solid alibi! Whether it was the first or second theft, our alibis are very sufficient!" Liu Long said somewhat excitedly: "Our alibis are at the Ya Yue Hotel. You can go investigate the records at the Ya Yue Hotel. At the time of the two thefts, Jiang Li and I were both at the Ya Yue Hotel."

  Bai Qiang was taken aback, if that's the case, then Liu Long and Jiang Li's alibis would be established, and their suspicions would be greatly reduced. Bai Qiang turned to look at Shi Lei and asked: "Shi, what do we do now?"

  Shi Ke silently and coldly laughed at Liu Long, "The mere hotel records can prove nothing, they can only prove that they once opened a room in the Ya Yue Hotel, it is not enough to prove that they were always inside the Ya Yue Hotel."

  Bai Qiang thought for a moment and said: "Shi younger brother, shall we go check out Ya Yue Hotel?"

  "No need! The Ya Yue Hotel must have their check-in records, and even if we investigate, it's useless! Old Bai, what's your police network account number? Lend it to me for a use!" Shi Lei said.

  Bai Qiang hesitated and said: "Shi, what are you planning to do?"

  "Take a look at the social security surveillance system of the Social Security Monitoring Division, and also the road monitoring system of the Traffic Bureau. Find something that interests me!" Shi Lei said.

  "Wow, you even know this!"

  Bai Lao Ge, you think these are secrets? Hurry up and give me the account number! I don't know how many days have passed, are those records still there?!

  From the server, Bai Qiang logged into the police network. Shi Lei, who was familiar with the police network, found the program of the Social Public Safety Surveillance System and then searched for the location points of public safety cameras near Ya Yue Hotel.

  Right behind the Ya Yue Hotel, there was a public security camera. Shi Lei immediately inquired about the video records of this camera on October 30th and November 8th.

  Shi Ke looked up and glanced at Liu Long, asking: "When did you guys check into the room at Ya Yue Hotel?"

  Liu Long looked at Shi Ke and his eyes dodged slightly before saying: "Eight o'clock tonight."

  "The time of the theft was 11:20 pm. From Ya Yue Hotel to the City Museum, it takes about 50 minutes by car, which means you must leave Ya Yue Hotel before 10:30!" Shi Lei opened the public security camera's recording and directly selected the time node at 8 o'clock on October 30th, then played it in fast forward.

  Liu Long's forehead was beaded with cold sweat, his breathing a bit rough, trying his best to calm himself down.

  At the time node of the video recording, when it reached 10:10, a figure emerged from the window on the second floor and threw down something like a rope ladder, then climbed down from the second floor!

  Shi Ke paused and looked at Liu Long, saying: "What else do you have to say now?"

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

  "Not until the Yellow River runs dry!" Shi Lei picked up the high-definition camera, aimed at the screen image, and began to capture the walking posture of the person in the image. At the same time, he used virtual graphics processing software to rebuild a 3D model animation. "Take two steps with your normal pace and let's take a look!"

  Liu Long took two unnatural steps, and the high-definition camera recorded it. The behavior dynamic capture program analyzed the behavioral dynamics characteristics and compared the similarity matching rate. The simple behavioral dynamics characteristic of walking was very obvious, and Liu Long's behavioral dynamics characteristics matched those of the man in the video at a rate of 95%!

  Bai Qiang's face broke into a smile, "Liu Long, are you still not admitting it?"

  Liu Long said stubbornly: "You don't have direct evidence!"

  "Your glasses, how many degrees are they?" Shi Ke suddenly asked.

  "This is a privacy issue, I refuse to answer!" Liu Long's uncooperative response.

  "You must answer this question, otherwise the current evidence is enough to detain you at the police station for further investigation!" Shi Lei's tone was calm and without a hint of threat.

  Liu Long's face changed color, and finally said: "Both eyes are 700 degrees!"

  "Haha, high myopia, that's really good news!" Shi Lei directly picked up his phone and dialed 114, then asked: "Hello, I'd like to ask, what eyeglass stores are around the city museum?"

  While inquiring, I searched for news about the eyeglass stores around the city museum.

  Dialing 114 for customer service, Shi Ke asked for all the registered eyeglass stores around the city museum. He recorded down their phone numbers.

  Bai Qiang was puzzled and curiously asked: "Shi, little brother, what are you asking the eyeglasses store for?"

  Liu Long's face looked even more unsightly!
