On the 11th floor of Buzhou mountain, Chihiro technology.

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

    They are no strangers to Vientiane life and death discs. Everyone here bought Vientiane life and death discs, and some bought more than one. The projection screen in front of them made many people have a new understanding of Vientiane group and admire Qin Bamboo Slips more. They thought of it in a moment, The current projection screen will certainly become another heavyweight product of Vientiane group in the future, and the market of this product is no smaller than Vientiane life and death plate. Therefore, it seems that the technology of Qin bamboo slips is really unfathomable and powerful.

    On the podium, where the blackboard should have been, now there is also a huge screen with a line of words: introduction to automatic driving technology.

    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, that is, an ordinary table. If it wasn''t for the projection in front of them, they all doubted whether they had an illusion.

    If I was just surprised before, I''m curious now. Does this projection appear out of thin air?

    Chen Hao turned around the table and found nothing. He immediately looked at Qin Bamboo Slips and asked, "boss, how did this projection screen appear and why didn''t I see any equipment?"

    Chen Hao''s question was also the question of others. They heard Chen Hao''s voice and immediately looked at the Qin bamboo slips. They urgently wanted to get the answer from the Qin bamboo slips.

    Qin Jian raised his hand, pointed to the roof, smiled and said, "look up."

    Chen Hao and other engineers quickly looked up.

    On the roof of the room, a semicircular device like a camera is installed in each of the four corners, like an inverted sea bowl. 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 Vientiane life and death disc? Only four projectors projected so many screens. This technology is too powerful.

    Qin Jian looked at the shocked expression of the engineers under the stage. There was no accident. The three-dimensional projector installed in the classroom was assembled by Qin Jian himself in the laboratory. In addition to Qin Jian''s room, it was installed here. This small three-dimensional projector Qin Jian is not ready to be sold on the market at present. Vientiane life and death plate has not been popularized yet, How could he take out the next generation of products? Now they can only be used internally.

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

    "That''s great!"

    "Boss, is this what you developed?"

    "This is amazing."

    "Can 3D projection technology be used like this?"

    “……”

    Chen Hao''s eyes glowed and asked, "boss, can we learn 3D projection technology?"

    Qin Jian said with a smile: "the technology is interlinked. Whether it is three-dimensional projection or automatic driving, it is actually image processing. As long as you learn the basic knowledge I teach you next, you can study not only automatic driving technology, but also three-dimensional projection technology in the future."

    "Well, first you get familiar with the operation of the screen. We''ll start the lecture later."

    Qin Jian said and made a gesture. Help content appeared next to the projection screen. People began to learn the gestures of control.

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

    Qin Jian began to lecture:

    "Autopilot technology is a close combination 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 autopilot decision-making system. Generally speaking, it is autopilot algorithm. This algorithm is mainly divided into rule algorithm and deep learning algorithm,

    Rule algorithm helps vehicles make decisions by artificially defining driving rules. The correctness of this algorithm is very low and it is prone to misjudgment. At the same time, with the increase of scene complexity, the scale of the algorithm will become very large, which is prone to redundancy. Moreover, it is difficult to greatly improve the performance in complex driving environment, so it is mostly used in simple scenes ，

    The deep algorithm is to process complex scenes through deep learning. After a large amount of data training, it can greatly improve the correctness of system decision-making and simplify the structure of decision-making system. However, this method also has the disadvantages of poor interpretability and poor adjustability, and the training results are very uncertain,

    Therefore, the automatic driving decision-making system will combine the rule algorithm and the deep learning algorithm, so that the simple scene can be defined and traversed at the top level, and the complex specific scene can be deeply trained by the deep learning algorithm at the bottom level. The combination of the two algorithms can improve the accuracy and stability of the decision-making system to the greatest extent. "

    The audience listened carefully. Qin Jian continued:

    "We will leave the hardware technology to the later stage. Today, let''s talk about the decision-making system. Whether it is rule algorithm or 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. Through the data fed back by the hardware, we can quickly judge the current environmental state, such as pedestrians, obstacles, zebra crossings, red street lights, and other road signs.

    Planning refers to various decisions made by the decision-making system to reach the destination, including path 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.

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

    These three layers are what we need to implement.

    For decision systems

    ”

    Qin Jian talks about autopilot technology in detail. Qin Jian has no hidden ideas about these peripheral technologies. Autopilot technology is a very complex technology. It is not that everything will be fine after the algorithm is written, but that it needs a lot of data training to have an algorithm that can be used, Qin Jian can''t spend a lot of time on the training of data sets. In the future, these things have to be handed over to these technicians. Therefore, Qin Jian has to let them have the most basic knowledge. Otherwise, they have no way to train algorithms. Of course, Qin Jian won''t talk about the core algorithms.

    In the following days, Qin Bamboo Slips gave them classes every day and asked them to do all kinds of algorithm training, just like a strict teacher.

    These technicians also study hard every day and absorb the things taught by Qin bamboo slips. Although these knowledge is only some peripheral knowledge in Qin Bamboo Slips, it is the most advanced automatic driving algorithm in the world for them. They are eager to learn and will seriously complete the assignments assigned by Qin bamboo slips, Many people practice until very late every day. If Qin Jianyi didn''t emphasize the need to ensure sufficient sleep time, many people only sleep four or five hours a day.

    Qin Jian was very satisfied with the learning attitude of these people, and he taught more vigorously.

    On this day, Qin Jian had just finished his class. His mobile phone rang. Qin Jian looked at Zhao Yueying''s phone and connected it immediately.

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

    Qin Jian replied, "yes, what''s up?"

    Zhao Yueying said with a smile: "good thing, you wait, I''ll go to the company to find you!"

    Qin Jian was about to ask what it was. When the phone hung up, Qin Jian immediately called him back: "what''s the matter with me?"

    Zhao Yueying said, "you''ll know when I arrive!"

    Qin Jian said in a deep voice, "I''m very busy now. If you don''t say anything, I won''t wait for you."

    Zhao Yue said angrily, "you are a real person. Well, I tell you, the experts of the ninth academy are very interested in the algorithm you use to encrypt the game and want to cooperate with you. We have arrived in Leizhou and are staying in the hotel now. I''ll find you later."

    Qin Jian immediately knew what was going on. Jiuyuan refers to the Kyushu Academy of Sciences, the largest scientific research institution in Kyushu. It has gathered top experts in various fields. Now they come to me for cooperation. There must be no way to take my algorithm, otherwise they won''t come to me.

    Qin Jian''s mind flashed and said to the phone, "OK, come here!"

    When the phone hung up, Qin Jian thought secretly that the people of the nine institutes were not easy to send. Since they came, they represented the will of Kyushu. This algorithm must be given. The difference is what they would exchange and what they want. If they asked for technology with empty words and white teeth, there would be no second words. They refused directly. Anyway, Lei Zhengsheng supported them, Compared with them, they can''t do anything about themselves, but listening to Zhao Yueying''s tone, they shouldn''t want to take it for nothing. In this case, I have to think about what conditions and things I will put forward with them later. This algorithm must not be given for nothing.

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

    One of the elders said, "OK, let''s go now."

    Another old man looked at Zhao Yueying and said, "Yueying, it''s really troublesome for you to come with our two old men this time. It''s an annoying job."

    Zhao Yueying said with a smile: "Grandpa Shi, you don''t have to be polite to me. I''m helping you and our group!"

    The old man, known as Grandpa Shi, said with a smile, "OK, OK, you girl doll can really talk. No wonder Lao Zhang likes you so much."

    The first old man said at this time, "OK, let''s not flatter each other here. Don''t let others wait for a long time."

    Zhao Yueying said with a smile, "don''t worry. Both grandpa are academicians of Kyushu. It''s his honor to wait a little longer for Qin bamboo slips."

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

    The old man surnamed Zhang disagreed and said, "what academician can''t even crack a little doll''s program. What academician does he say? We''re here to talk about cooperation this time, not to make a show. Lao Shi, I can remind you, don''t put your vice president''s name when you meet Qin Jian."

    The stone old man smelled the speech and said, "Lao Zhang, when did I put on the spectrum what you said? You have a bigger temper than anyone. I''m afraid you''ll offend people later."

    The old man surnamed Zhang snorted, "my temper is the scorer."

    At this time, Zhao Yueying interrupted, "let''s go, Grandpa. Don''t make people wait for a long time."

    After hearing the speech, the two elders laughed and stopped bickering. They left the hotel and went to Buzhou mountain.
