Chapter 310 Police Cooperation

Not long after Guo Yuan returned to Hangzhou, he received a call from Bai Jingwen.

Bai Jingwen's laboratory is in Shanghai, and he wants to invite Guo Yuan to come and visit.

Guo Yuan thought about it for a while and agreed. Just two days later, Guo Yuan planned to ask 01 to send the algorithm. Now that Academician Bai wants to meet him, he can send the algorithm himself.

Two days later, Guo Yuan brought the algorithm to Bai Jingwen's laboratory.

After the two exchanged pleasantries, Guo Yuan turned on his portable laptop, and briefly introduced the dual-motor drive algorithm control program with Bai Jingwen.

Guo Yuan introduced the design framework of the entire algorithm and the power control scheme to Bai Jingwen.

Bai Jingwen did not expect Guo Yuan to complete the structural design of the algorithm in such a short time.

After listening to Guo Yuan's introduction, Bai Jingwen verified the logic diagram of the algorithm framework on paper for a long time.

In Bai Jingwen's opinion, Guo Yuan's design is very rigorous. It is precisely because the algorithm is rigorous enough that he did not fully understand the design ideas in some places.

He asked Guo Yuan for advice on the operating nodes in the motor drive, and finally matched them with logical nodes in the algorithm design until he could no longer ask new questions, and was convinced by Guo Yuan's design.

"Guo Yuan, your algorithm framework design is really ingenious and logically rigorous. Your algorithm can perfectly solve the power control problems I encountered in previous projects."

"Then if there are no problems, I can start developing today. How did you arrange the equipment here, Academician Bai?"

Bai Jingwen replied with a relaxed expression: "The previous equipment is no longer available. Next, we will use your robotic arm as the basis to redesign the dual-motor drive solution. In the future, we can also directly help you improve the robotic arm."

Guo Yuan smiled and nodded.

Seeing this, Academician Bai felt more and more that it was the right choice for him to ask Director Liu to help matchmaking and cooperate with Guo Yuan.

But what Bai Jingwen didn't know was that if Guo Yuan wasn't afraid to frighten him, how could it take two days?They can start that day.

"Alright then, I'll learn more from you, Academician Bai."

Since Guo Yuan is so eager to learn, Bai Jingwen sent Guo Yuan the original project design drawing he found yesterday, so that Guo Yuan could familiarize himself with it first and try to make changes to adapt to the project of the robotic arm.

Looking at the schematic diagram of the mechanical structure on the screen, the 01 in Guo Yuan's mobile phone entered the learning state in an instant, and the parts in the design drawing on the screen had already begun to be simulated and constructed on the 01.

After finishing the work, 01 fed back the simulation results to Guo Yuan through the Bluetooth headset.

Bai Jingwen didn't keep pouring this knowledge into Guo Yuan, he wanted to see if Guo Yuan could understand.

But when Academician Bai walked behind Guo Yuan, he realized that Guo Yuan was much more receptive than he thought.

Watching Guo Yuan write and draw on the paper at hand, although the content is fragmented, he can still vaguely see that this is the torque compensation process during the dual motor drive process.

Bai Jingwen stood behind Guo Yuan and looked at it for a while. When he saw that Guo Yuan had clearly analyzed the whole process of the motor drive, when he saw that Guo Yuan was obviously trying to split and modify the structure, Bai Jingwen looked at it with complicated eyes. He glanced at the back of Guo Yuan's head, then turned and walked away.

Now he must admit that there is really a gap between people. Guo Yuan can complete the process of understanding, familiarization, and analysis in such a short period of time. He may even start the design of the dual-motor-driven robotic arm adaptation solution today. , It took him half a month to do this design.

Such talents should do scientific research. How can they spend their energy on the market? Isn't this a waste?

The more Bai Jingwen thought about it, the more uncomfortable he became.

At the same time, Bai Jingwen also understood why Director Liu admired Guo Yuan so much.

In the afternoon, Guo Yuan went to Bai Jingwen and showed him the sketch of his redesign.

Bai Jingwen looked at Guo Yuan's redesigned design. Although there were some problems, he had to admit that the design was quite excellent, with a complete main structure and reasonable kinematic structure, and only some small positions needed to be adjusted.

Bai Jingwen pointed out the problems to Guo Yuan in front of the design, and Guo Yuan listened carefully to the other party’s opinions. As soon as Bai Jingwen mentioned the problem, Guo Yuan realized that when he completed the design with the help of 01, he really did not consider the changes in posture. The center of gravity shifted, this is the gap in experience.

When he was about to go home at night, Guo Yuan's design was basically completed, and both he and Bai Jingwen thought it was time to enter the manufacturing process.

Then Guo Yuan called Zhou Songfeng and asked Zhou Songfeng to manufacture a new robotic arm as soon as possible according to the design drawings, and not to inject the operating system.

Three days later, Guo Yuan got the finished product from Zhou Songfeng.

Guo Yuan looked at the reassembled robotic arm in front of him.

The joints of the new robotic arm are obviously a bit bloated compared to before. Because of the small size of the robotic arm, it now looks like several mechanical blocks spliced ​​together.

Guo Yuan injected the algorithm developed by 01 into it, and then put on Lin Yumo's head-mounted brain-computer interface to try to control the robotic arm.

"Smooth, very smooth!" This is Guo Yuan's biggest feeling.

This robotic arm is like his third arm, which can be controlled with a single thought.

When Guo Yuan was enjoying himself, Cheng Shuqing ran over and said, "Boss, someone is looking for you outside."

"Looking for me? Who is it?"

"It's the police."

Guo Yuan was taken aback when he heard the words, and immediately took off the head-mounted brain-computer interface and asked, "Where are they?"

"In your office."

"Did you say anything?"

Cheng Shuqing shook her head.

Guo Yuan and Cheng Shuqing immediately took the elevator back to their office.

There were two middle-aged men in casual clothes sitting in his office.

Seeing Guo Yuan coming in, the two got up and walked towards Guo Yuan at the same time, and one of the older ones extended his hand to Guo Yuan: "Mr. Guo, hello, I am Zhou Zhengyang from the senior professional technical department of the police. Shao Ming."

"Hello, two police officers. I wonder why you two came to our company?"

"Mr. Guo, we are very interested in the patented image recognition technology submitted by your company some time ago. I wonder if your company has any idea of ​​cooperating with our police?"

Guo Yuan was taken aback when he heard the words, but he didn't expect the police to come for this.

"Are the two here on behalf of the Hangzhou police?" Guo Yuan asked tentatively.

"No, we are here on behalf of the public security organs across the country."

Guo Yuan's expression became serious when he heard this, and he immediately asked Cheng Shuqing to call Zhao Liyi.

The image recognition algorithm is separated from the sweeping robot by Zhao Liyi, and he feeds it out bit by bit. No one knows this algorithm better than him.

Soon Zhao Liyi came over, and Guo Yuan introduced himself to Zhao Liyi and Zhou Zhengyang.

Zhao Liyi's expression became serious when he learned of the two people's intentions: "Officer Zhou, Officer Shao, please move to the conference room, I will show you the algorithm of our company in detail."

Naturally, Zhou Zhengyang and Shao Ming would not refuse. They came here to confirm how strong the image recognition algorithm of Future Technology is, and whether they can cooperate.

Not long after the two came to the meeting, Zhao Liyi brought the PPT and started showing it.

"Two police officers, compared with our competitors, our image recognition technology is ahead of other companies in terms of recognition efficiency, recognition rate, and information acquisition breadth. Next, I will introduce the specific content."

Turning the page of the PPT to the next page, Zhao Liyi began to introduce the recognition rate of image recognition. The recognition rate as high as 99.99% surprised Zhou Zhengyang and Shao Ming.

The technologies they were exposed to before were only about 90%, and the technology submitted for review by Future Technology only said to have a recognition rate of 95%. Now it seems that Future Technology has reservations when it is submitted for review!

However, they are really curious about how Future Technology achieves this close to 100% recognition rate.

Zhao Liyi didn't know what the two of them were thinking. He played a video directly. In the video, there was a scene of a subway station in the morning rush hour. There were endless crowds, including white-collar workers, students, and old men and women carrying vegetable baskets.
After the video was played, Zhao Liyi said confidently: "Two police officers, next we will use image recognition technology to analyze this video, and the algorithm will mark all the figures in the video."

Zhao Liyi said while importing the video into the image recognition process.

Everyone waited for about 30 seconds, and the video identification log has been analyzed.

"As you can see, the total duration of this video is 2 minutes and 54 seconds. Our image recognition algorithm only took 14 seconds to analyze the entire video. Now let's take a look at the newly generated video."

After Zhao Liyi finished speaking, he double-clicked again to start playing the new video. This time, in every scene in the video, every figure was marked by a box.

These annotations include gender, clothing, approximate age, distance from the camera, and more.

No matter how complex the scene is, the algorithm can identify and mark even partially occluded figures.

After watching the video, Shao Yang asked, "Mr. Zhao, I have to say that the technology you showed just now surprised me. Such a high recognition rate is many times higher than that of the human eye itself.

But as you said, other technology providers can only guarantee a 90% recognition rate, so how does Future Technology achieve such a high recognition rate?How can I trust the authenticity of your demo video. "

When Zhao Liyi was asked this question, he was a little dazed. After feeding the image recognition algorithm for so long, he thought he already knew the algorithm of image analysis very well.

He thought for a while and explained the reason for the image recognition: "Officer Shao, of course it's because our image analysis algorithm is good enough.

Our image recognition algorithm analyzes image features through a multi-layer analysis algorithm.

This multi-layer analysis algorithm has undergone several rounds of optimization, and only then has the current recognition rate of 99.99%.

As for the authenticity you mentioned, we can record a video on the spot for testing.

Or Officer Shao, we can directly use your video for analysis. "

After saying this, Zhao Liyi turned his head to look at Shao Ming, apparently handing over the decision to Shao Ming.

Before Shao Ming could speak, Guo Yuan connected to the camera in the conference room and projected the image onto the PPT.

The content of the video is exactly the video surveillance screen of the meeting room where they are located, and everyone is marked on the screen in real time.

Zhou Zhengyang and the others looked at the picture on the curtain and tried to turn their heads to cover their faces, but the frame on the screen still locked them, and even as time went by, the text in the frame became more and more abundant, such as Zhou Zhengyang’s His police status is already listed in the marked box.

Zhou Zhengyang turned his head and said to Guo Yuan in surprise: "Mr. Zhao, your image recognition is not just for character recognition, is it?"

Zhao Liyi smiled and nodded: "Yes, but this service will not be released this time. Our image recognition service will be associated with character analysis capabilities to analyze as much character information as possible."

Shao Ming, who was next to Zhou Zhengyang, witnessed this scene, and his doubts about the image recognition algorithm were much less. He was discussing something with Zhou Zhengyang in a low voice, and his expression was a little excited.

Zhou Zhengyang shook his head after hearing his words. To be honest, Zhou Zhengyang no longer doubts the authenticity of future technology, but he is more concerned about how future technology can identify such information so efficiently.

Zhao Liyi fell into deep thought after watching several people discussing a few words, he tentatively said: "Everyone has seen the video, and the algorithm has also output a recognition log record, which will record the identified person's information in detail, Similarly, our service will also return the identification content to the user in the form of data, which is convenient for the user to perform secondary processing."

After finishing speaking, Zhao Liyi took a while, waiting for the two to ask questions, but neither of them spoke. Seeing that everyone had no doubts, Zhao Liyi continued: "After talking about the recognition rate, let's continue to look at the time-consuming recognition. In fact, Mr. Lin just now The demo camera recognition screen has already demonstrated this part of the content, but I still want to use a simple demo to demonstrate it intuitively for everyone.”

After saying this, Zhao Liyi found two pictures from the computer catalog, one was a picture of ordinary people, and the other was a picture taken by an infrared lens at night.

When analyzing these two pictures using the image recognition interface, the recognition result was obtained almost instantly.

Zhao Liyi opened the identification log and showed it to everyone for viewing. It takes 32ms for ordinary picture recognition, but 27ms for infrared photos.

This speed stunned Shao Ming.

He immediately took out a USB flash drive and handed it to Zhao Liyi: "Mr. Zhao, can I trouble you to scan this video for us?"

Zhao Liyi nodded, took the USB flash drive and inserted it into the computer.

There is only a 2-minute video in the USB flash drive. The video should be a surveillance camera at an intersection, and all the vehicles passing by are vehicles.

Zhao Liyi clicked on the video and imported the image recognition algorithm.

After the recognition, Zhao Liyi clicked on the video.

The driver and co-pilot seat of each passing vehicle are marked by a red box, with some of their personal information in the red box.

In this day and age, personal information cannot be hidden on the Internet at all. You can know it no matter what you want, without resorting to the police. Zhou Zhengyang and Shao Ming also know this.
