Chapter 306 Image Recognition Algorithms
The employees of Future Technology were busy working on the company's sweeping robot, and Guo Yuan didn't forget about Longcheng Biology. He called Lin Yumo, introduced Zhou Songfeng's company to Lin Yumo, and sent Lin Yumo a copy of the basic information of Zhou Songfeng's company's robotic arm.

After Lin Yumo received the information, she put down her current research on AIDS and turned to read the information on the robotic arm.

After Lin Yumo browsed through the information on Zhou Songfeng's robotic arm, she felt that there were many things she couldn't understand. Lin Yumo believed that one must have basic awe for personal unknown knowledge.

So she directly asked 02 to help her collect papers and documents related to the robotic arm on the Internet.

This task should not be too simple for the current 02. After two or three seconds, the sorted documents appeared on Lin Yumo's desktop.

After browsing some relevant information, Lin Yumo has a general understanding of the robotic arm. The robotic arm is composed of a series of joints and connecting rods. The positions of the joints have a variable setting, and each joint has its own function settings.

Rotary joints that are generally divided into position and angle are mainly composed of transmission devices, motion shafts, drives, and sensors...
Lin Yumo read from the most basic part, understanding the instructions about the mechanical arm bit by bit.

"Yumo, it's almost time, let's watch after eating!" Su Yurou pushed open the door and walked in.

Lin Yumo nodded, and took the boxed lunch from Su Yurou.

The lunch box is from the Longcheng Biological Canteen. It has two meat dishes, one vegetarian dish and one bowl of soup. The taste is not good, but it is very clean.

Lin Yumo quickly finished her lunch, drank half a glass of water, and then turned her attention back to the computer screen.

With the help of 02, Lin Yumo quickly learned that there are several types of motors used in the robotic arm. Generally, engineers will divide the motors into four categories according to the needs: DC motors, stepping motors, servo motors, and steering gears.

After comparing the performance and working mechanism of these types of motors, Lin Yumo found that the stepper motor was the optimal solution for the motor configuration of the robotic arm he designed.

The stepper motor can start quickly, allowing the robotic arm to respond quickly to human needs.

It supports forward and reverse rotation and stop rotation, making the robotic arm more flexible. As an external system for brain-computer interface docking, the robotic arm must adapt to a variety of work scenarios, and it must be at least 80% of the flexibility of a human arm to be practical.

The stepper motor can change the pulse frequency and speed in a wide range. In the future, whether it is life assistance or test scenarios that require high precision, it can well support the operation of the robotic arm.

Although the robotic arm does not require a high load capacity in most daily life, the large output torque of the stepping motor made Lin Yumo decide to choose it as the preferred motor category.

"02, what kind of motor does Zhou Songfeng use?"

"It's a stepper motor."

Lin Yumo was relieved, and continued to read about his mechanical arm knowledge.

The knowledge of motor classification is just the foundation. How the motor cooperates with the controller and reducer is the key core of hardware design.

When Lin Yumo saw the details of the speed reducer, it was already late outside, and Lin Yumo, who felt physically exhausted, came back to her senses, unknowingly she had read the information for a whole day.

Lin Yumo stretched, she felt that her body was close to its limit, and that was all she could do today.

Lin Yumo turned off the computer, stood up and stretched her neck, then turned and went home.

Back home, Lin Yumo's mind was also full of robotic arms.

As the saying goes, you think about it every day and dream at night, and tonight Lin Yumo really dreamed about the mechanical arm.

Menglilongcheng Biology not only produced a suitable mechanical arm for supporting the brain-computer interface, but also produced other supporting equipment, and even produced a mecha.
"Dinglingling~" The ear-piercing sound of the alarm interrupted Lin Yumo's dream.

Lin Yumo washed her face and felt a lot more awake.

While eating breakfast, she thought that if she could realize what she dreamed of, then she might have a chance to become the richest man in the world.

Recalling the auxiliary robotic arms on her arms in her dream last night, Lin Yumo couldn't help but smile, from simply replacing humans to complete various tasks to assisting humans in their own movements.

If it does come to fruition, it would be a leap forward.

Lin Yumo has seen all kinds of exoskeleton armor in movies more than once, ranging from civilian to military.

Civilian load-bearing, assistance for the disabled, fire assistance, military individual exoskeleton, there are many other types besides these, and the diverse nature of human work has created more diverse needs.

With the assistance of machinery, the work efficiency of human beings will be greatly improved, all of which come from human beings' unremitting pursuit of technology.

Limited by flesh and blood, unable to bear heavy objects, the five senses have a huge gap compared with machines in terms of environmental perception. In extremely harsh environments, human beings are limited by factors such as temperature and the work efficiency drops seriously.

If machines and humans can be combined, it will be a big step from reality to the future.

The physical limit of human frailty is there. In order to change the reality of limited manpower, Lin Yumo believes that it is not only film works, but there must be many laboratories around the world doing research in this area.

After breakfast, Lin Yumo came to the company. Compared to Guo Yuan, the boss Lin Yumo was really hardworking. After reading the relevant information on the robotic arm, she went to the laboratory below to communicate with the relevant technicians.

At the same time, for Future Technology, Zhao Liyi was already waiting for him in Guo Yuan's office.

Guo Yuan arrived late at 10:[-].

Zhao Liyi is already used to Guo Yuan's working hours. He handed Guo Yuan a folder and said, "Boss, when I was building the Sweeper App, I found that the image recognition technology in our sweeping robot is very mature. I think we can use image recognition technology to build a smart door lock."

Upon hearing this, Guo Yuan took the document and quickly browsed through it, then said, "Tell me about your specific thoughts."

"This starts with image recognition technology"

From Zhao Liyi's mouth, Guo Yuan learned why he had this idea.

When Zhao Liyi and the technical side are working on the APP corresponding to the sweeping robot, they need to conduct various docking tests.

Among them, the camera test of the sweeping robot is definitely the focus.

When Guo Yuan was working on the algorithm of the sweeping robot, he directly handed over the image recognition to 01.

The thinking logic of AI and humans is completely different, and the programs written by AI are absolutely more perfect than those written by humans.

Therefore, after Zhao Liyi studied the image recognition algorithm for a period of time, he found that the image recognition algorithm carried in the company's sweeping robot was completely different from the common domestic algorithm.

At present, domestic image recognition generally uses the "representation learning method" in deep learning. The deep learning method includes multiple layers, generally 5 to 2 layers. Different layers will analyze different abstract features in the image, such as the location of the edge of the object, edge features, combination form of local edges, combination layer feature analysis, etc.

Deep learning is to use these layers to analyze the original data of the picture for feature representation, and then perform comprehensive feature analysis.

The image algorithm in the sweeping robot is completely different.

The core algorithm and self-learning ability determine the upper limit of the program that can summarize and record data by itself.

The AI ​​intelligence carried in the sweeping robot is so high that it completely replaces the part of image data analysis that requires humans to be responsible for.

Even part of the generalized artificial intelligence can be done by itself.

After confirming this situation, Zhao Liyi immediately took out the technical module of image recognition separately.

Then start to configure external programs for the artificial intelligence program in the technology module to complete the logic of recognizing pictures, and use this part of the logic to distinguish the shape, color, material and other characteristics of objects in the picture.

After artificial intelligence can distinguish and classify objects in the picture, the analysis of video data is a matter of changing the task in real time. If the audio is removed, the video is the combined data of a large number of picture frames, and the video is parsed into independent picture frames for continuous analysis.

In order to test the upper limit of image recognition technology, Zhao Liyi has been recording various pictures in the next period of time.

So when the employees of the technical department approached Zhao Liyi to discuss the project of the language knowledge base, they found that Zhao Liyi no longer typed codes.

If it weren't for browsing his own selfie photos, there are all kinds of angles.

Or looking at pictures of all kinds of beauties.

There are even photos of various handsome guys.

This made many employees in the technical department feel that something was wrong with their boss.

After collecting a large number of human images, Zhao Liyi built a database of these picture materials, and then Zhao Liyi started the development of the image recognition model, first developing image data detection tools.

Each picture is an array of pixels. When the algorithm analyzes the picture, it is analyzing the color value data of these pixels.

Although the technical level of the artificial intelligence program is very high, the current program cannot understand natural language, and cannot directly load relevant papers to understand and analyze relevant knowledge. Therefore, Zhao Liyi did not blindly let the artificial intelligence learn and train the image analysis ability on its own.

Instead, manual guidance was adopted.

A week passed like this, and the image recognition module was really taught by him.

When this module is loaded on the smart door lock, the accuracy and speed of face recognition surpass the best smart door locks on the market.

At present, Zhao Liyi has tested more than 10 times, and there is no single mistake, and the safety has reached 100%.

And whether you are wearing a mask or a hat, as long as your eyes are not covered, the image recognition system can be activated in seconds.

The reaction speed is invincible.

It is precisely because of this that Zhao Liyi is so confident that he wants Guo Yuan to build an additional smart door lock.

After listening to Zhao Liyi's words, Guo Yuan felt that it was not a big problem. He nodded and agreed after thinking for a while, but Wang Hui was busy with the production line recently.

Before I knew it, it was December 12st, and today is the last day of 31.

Except for the necessary operation and maintenance personnel of Future Technology, all other employees have been on vacation.

The wages and bonuses for December were also paid to the employees' salary cards yesterday.

Inside Future Technology Company this afternoon, cheers erupted from time to time in the work area when the bank's SMS notification arrived.

The bonus here is not a year-end bonus, but an additional bonus from Guo Yuan.

The development of future technology this year can be said to be like riding a rocket.

The company's current valuation is already 500 billion Huaxia coins, and this is just a valuation. If it goes public to make money, the market value of Future Technology should be around [-] billion.

So Guo Yuan generously gave a bonus to all the employees of the company.

The most is 3, and the least is 1.

The company's profits are good, and Guo Yuan will naturally not treat his brothers badly.

And there will only be more year-end bonuses next month, so that everyone will have a good year, and next year everyone will have the enthusiasm to devote themselves to new jobs.

Guo Yuan asked Liu Xiaoyin to do the awarding of bonuses.

Guo Yuan has no time to take care of these things, he still has a lot of work at hand.

At present, what Guo Yuan is most concerned about is naturally Wang Hui's production line.

Yesterday morning, Wang Hui led Guo Yuan to the factory he bought to inspect the results.

After Guo Yuan's on-the-spot investigation, he looked at the various data made by Wang Hui on the tablet computer and finally nodded in satisfaction.

Seeing that Guo Yuan had no doubts about the project, Wang Hui and several people in charge of purchasing the production line clapped their hands and cheered in celebration.

This project has a tight schedule and heavy tasks. Everyone has been working under pressure, and because Guo Yuan is very focused on it, it is still the company's core project for next year. It would be a lie to say that it is not nervous.

Now that the project has been approved by the boss, everyone is very excited. Several younger ones are already discussing where to go for a drink to celebrate at night.

Seeing how excited these people were, Guo Yuan didn't participate, but just applauded to express encouragement. In the end, it was Wang Hui who calmed down the emotions of the group members.

After the group of people quieted down, Guo Yuan said with a smile: "Everyone is doing well. The task of purchasing the factory has been successfully completed. This time, the bonus will be given to you at the highest level."

Everyone smiled when they heard the words, and their work was not in vain during this period of time.

After dealing with the company's affairs, Guo Yuan went to the airport to send Reiko Sayama and Jones off on the afternoon of the 30th.

Their affairs in Asia have not been dealt with, but the New Year is coming soon, and they have to go back to the United States.

Especially Reiko Sayama, his cheap father seemed to want to make up for Reiko Sayama's lack of paternal love, and kept making Reiko Sayama come back to celebrate the New Year.

Reiko Sayama had no choice but to go back first.

After sending Sayama Reiko away, Guo Yuan didn't really want to stay in Hangzhou anymore. He arranged a private jet in advance. At 3 o'clock this afternoon, Guo Yuan boarded the private jet and returned to Bingzhou.

Cheng Shuqing didn't come with her this time, and went home for the New Year by herself.

After Guo Yuan returned to Bingzhou, he went to a nearby supermarket to buy some meat and vegetables, and cooked a large table of dishes.

At 8 o'clock in the evening, Guo Yuan heard the sound of the door opening, and immediately ran to open the door of his own house.
