Chapter 102 Autonomous Driving Algorithm (seeking subscription)

On the eleventh floor of Buzhou Mountain, Qianxun Technology.

In a huge room with a classroom sign, the expressions on the faces of the 37 engineers who signed the non-disclosure agreement were a little surprised. There was only a keyboard on the table in front of them, and the screen was a projected virtual screen. .

They are not unfamiliar with the Vientiane Life and Death Disk. Everyone here has purchased the Vientiane Life and Death Disk, and some have purchased more than one. The projection screen in front of them has given many people a new understanding of the Vientiane Group and at the same time, they have a new understanding of the Vientiane Group. They also admire it even more. They thought in an instant that the projection screen in front of them will definitely become another heavyweight product of Vientiane Group in the future, and the market for this product is not smaller than Vientiane Life and Death. The technology is really unfathomable and amazing.

On the podium, where the blackboard was supposed to be, now a huge screen is also projected, on which a line of words: Introduction to Autonomous Driving Technology is displayed.

The engineers began to try to understand the projection in front of them. They looked at the table and found that there was no equipment on the table. It was an ordinary table. If it weren't for the projection in front of them, they all suspected that they had hallucinations.

If you were a little surprised before, you are curious now. Does this projection appear out of thin air?

Chen Hao circled the table and found nothing. He immediately looked at Qin Jian and asked: "Boss, how did this projection screen appear? Why didn't I see any equipment?"

Chen Hao’s question was also a question of other people. When they heard Chen Hao’s voice, they all looked at Qin Jian, eager to get an answer from Qin Jian.

Qin Jian raised his hand and pointed to the roof, and said with a smile: "Look at the top."

Chen Hao and the other engineers hurriedly looked up.

On the roof of the room, a semi-circular device like a camera is installed in each of the four corners, like a sea bowl that is upside down. At this time, these devices are projecting images downward.

Everyone was shocked at this time. Is this a three-dimensional projector? How is it different from the Vientiane Life and Death Disk. Only four projectors project so many screens. This technology is too powerful.

Qin Jian looked at the shocked expressions of the engineers in the audience. There was no surprise. The 3D projector installed in the classroom was assembled by Qin Jian in the laboratory. Besides Qin Jian’s room, it was installed here. The small three-dimensional projector Qin Jian is not yet ready to go on sale. The Vientiane Life and Death Disk is not yet popular. How could he bring out the next generation of products and now only use them internally.

Qin Jian smiled and said, "This is the next-generation experimental product of Vientiane Group. How do you feel?"

"so good!"

"Boss, did you develop this too?"

"This is really amazing."

"Can 3D projection technology be used in this way?"

"..."

Chen Hao glared in his eyes and asked: "Boss, can we learn 3D projection technology?"

Qin Jian smiled and said: "Technology is interlinked. Whether it is 3D projection or autonomous driving, it is actually the processing of images. As long as you learn the basic knowledge that I will teach you next, then you can not only study the automatic Driving technology, even three-dimensional projection technology can also be studied."

"Well, you guys will get acquainted with the operation of the screen first, and we will start lectures later.

Qin Jian said, making a gesture, and help content appeared next to the projection screen, and everyone began to learn how to manipulate gestures.

After about ten minutes, everyone in the audience was basically familiar with the operation of the projection screen.

Qin Jian began to lecture:

"Autonomous driving technology is a close integration of hardware and software. In terms of hardware, the core equipment is mainly ultrasonic radar, camera, millimeter wave radar, lidar, solid-state radar, and multi-sensor. In terms of software, it is the automatic driving decision-making system, which is popular. In terms of autonomous driving algorithm, this algorithm is mainly divided into rule algorithm and deep learning algorithm.

The rule algorithm helps vehicles make decisions by artificially defining driving rules. The accuracy of this algorithm decision is very low, and it is prone to misjudgment. At the same time, as the complexity of the scene increases, the scale of the algorithm will become very large and easy to appear Redundant situation, and the performance is difficult to greatly improve in a complex driving environment, so it is mostly used in simple scenarios,

The deep algorithm is to realize the processing of complex scenes through deep learning. After a large amount of data training, it can greatly improve the correctness of the system decision and simplify the structure of the decision system, but this method also has poor interpretability and adjustment The shortcomings of poor sex, and the results of training have great uncertainty,

Therefore, the automatic driving decision-making system will combine the rule algorithm and the deep learning algorithm, so that simple scenes can be defined at the top level for scene traversal, and deep learning algorithms are used at the bottom to conduct deep training for complex and specific scenes. The combination of these algorithms can maximize the accuracy and stability of the decision-making system."

Everyone in the audience listened very seriously, and Qin Jian continued:

"The hardware technology, we will leave it to the later stage. Today we will talk about the decision system first. Whether it is a rule algorithm or a deep learning algorithm, they are all to solve three problems.

Perception, planning, and control,

Perception refers to the ability of the decision-making system to perceive the environment. The data fed back by the hardware can quickly determine the current state of the environment, such as pedestrians, obstacles, zebra crossings, red street lights, and various road signs.

Planning refers to the various decisions made by the decision-making system to reach the destination, including route planning, driving planning, safety planning, action planning, and obstacle avoidance planning. The purpose of planning is to ensure that vehicles can reach the destination safely. destination.

Control refers to the precise control of the vehicle by the decision-making system. It will compare the current state of the vehicle with the expected state to output specific control actions.

These three layers are what we need to implement in detail.

For the decision system...

"

Qin Jian talks about autonomous driving technology in detail. For these peripheral technologies, Qin Jian has no hidden ideas. Autonomous driving technology is a very complicated technology. It is not that everything will be fine after the algorithm is written, but a lot of work is required. Only by using the data training of Qin Jian can we have an algorithm that can be used. It is impossible for Qin Jian to spend a lot of time on training the data set. In the future, these things have to be entrusted to these technicians. They have to have the most basic knowledge, otherwise they will not be able to train the algorithm at all. Of course, Qin Jian will not talk about the core algorithm.

In the following days, Qin Jian will teach them every day, and at the same time let them do various algorithm training, and become a strict teacher.

These technicians also take out the milk to learn every day and absorb what Qin Jian teaches them. Although this knowledge is only peripheral knowledge in Qin Jian, it is the most advanced autonomous driving in the world for them. Algorithms, they are studying eagerly, and will earnestly complete the homework assigned by Qin Jian. Many people practice every day before going to bed until late. If it is not for Qin Jianyi’s emphasis on ensuring adequate sleep time, many people Only sleep for four or five hours a day.

Qin Jian was very satisfied with the learning attitude of these people, and he became more energetic in teaching.

Qin Jian had just finished class that day, and the phone rang. Qin Jian looked at Zhao Yueying's phone and immediately connected.

Zhao Yueying's voice came: "Qin Jian, are you in the company?"

Qin Jian replied: "Yes, what's the matter?"

Zhao Yueying smiled and said: "Good thing, wait, I will go to the company to find you!"

Qin Jian was about to ask what was going on. The phone hung up, and Qin Jian immediately called him back: "What are you looking for?"

Zhao Yueying said: "You will know when I arrive!"

Qin Jian said solemnly: "I am very busy now. If you don't say anything, then forget it. I won't wait for you specifically."

Zhao Yueying was annoyed: "You are a real person, okay, let me tell you, the experts of the Ninth Academy are very interested in the algorithm you use to encrypt games, and want to cooperate with you. We have already arrived in Leizhou. Checking in at the hotel, I will find you later."

Qin Jian immediately knew what was going on. The Ninth Academy refers to the Kyushu Academy of Sciences, which is the largest scientific research unit in Kyushu. It has gathered top experts in various fields. Now they come to me for cooperation. They must use my algorithm. There is no way, otherwise you won't come to me.

Qin Jian had a thought in his heart, and said to the phone: "Okay, come here!"

When the phone was hung up, Qin Jian thought secretly that the people from the Ninth Academy are not easy to send. Since they are here, they represent the will of Kyushu. This algorithm must be given. The difference lies in what they will exchange. And what do you want, if you want to ask for skills, there is nothing else, just refuse, anyway, there is thunder to support yourself, they can't compare themselves to them, but listen to Zhao Yueying's tone, they It shouldn't be for nothing. In this case, I have to think about what conditions and what they want. This algorithm certainly cannot be given for nothing.

Qin Jian thought about it. In a room in a Leizhou hotel, Zhao Yueying walked from the balcony to the living room and smiled and said to the two old men: "Qin Jian is in the company, we can go there now."

One of the old men said: "Okay, then we will pass now."

Another old man looked at Zhao Yueying and said, "Yueying, this time I really trouble you to accompany our two old men. This is an offensive job."

Zhao Yueying smiled and said, "Grandpa Shi, you don't have to be polite to me, I am helping you and our group!"

The old man, known as Grandpa Shi, smiled and said, "Okay, okay, you girl can really talk, no wonder Lao Zhang likes you so much."

The old man who spoke first said at this time: "Okay, let's not tout each other here, don't let people wait for a long time."

Zhao Yueying smiled and said: "No hurry, the two grandpas are both academicians of Kyushu. It is his honor for him to wait a while for Qin Jian."

The old man surnamed Shi smiled and said, "Well, I'm not in a hurry when you say that."

The old man surnamed Zhang disapproved: "Academician, even the program of a little doll can't be cracked, or academician. We are here to discuss cooperation this time, not to show off, Lao Shi, I can remind you, I will see you later. With Qin Jian, don’t play your vice president's general."

The old man Shi Xing was a little displeased when he heard the words: "Lao Zhang, what are you talking about, when did I make a score, and when you have a stronger temper than anyone else, I am worried that you will offend people later." "

The old man surnamed Zhang snorted: "My temper is the one who scores."

At this time, Zhao Yueying interjected: "Let's go, two grandpas, don't make people wait too long."

Hearing the words, the two elders laughed, stopped quarreling, left the hotel and headed to Buzhou Mountain.
