Chapter 51

Liang Shicheng calmed down in front of the computer screen and thought deeply about Professor flanker's teaching.

The seemingly insignificant patterns on the trunk of that special truck are irregular grid patterns in the eyes of ordinary people, which is just an appearance.

But when he used drugs and gained insight into another level of the world, he could see other pictures, that is, camouflage.

Although it is reasonable to say that the humanoid driving system extracted with the universal editor is the same as people at the software level, it should not be caught.

However, in order to be compatible with other programs, the hardware of the whole driverless system is a higher definition camera than the human eye. In other words, as long as the resolution of the visual system is high enough, you will see the inner image.

The structure of human eyes is special. The eyeball is actually a camera with ultra-small recognition area but extremely high resolution within the recognition range. The picture that people finally see is spliced after continuous scanning of the eyes.

The scanning speed and splicing speed are limited by the computing power of the brain, so the human eye can achieve HD at the hardware level, which is limited to the ability of the brain. When looking at panoramic graphics, you can only feel a "thumbnail".

Previous drugs did not change the eyes, but changed the processing speed of the brain, thus upgrading the whole graphics system of the human brain.

However, for Liang Shicheng, the problem of solving the accident is more urgent now. He has no time to take care of the drug. He can only pay attention to observing more after taking the drug the next time he has plenty of brain power.

The first problem to be solved now is how to avoid the recurrence of such accidents. It is impossible to make major changes to the existing system, otherwise the early reliability data will be discarded, so we can only patch it.

At present, the fastest solution that can be thought of is to add a cheap lidar as an auxiliary. No matter how the pattern is deceived, the radar will not look at the pattern. It only has black and white in its eyes, and it will only judge whether there are obstacles.

But suddenly Liang Shicheng remembered again. According to Professor flanker, the camouflage pattern on the trunk was deliberately made by someone. The way is one foot higher and the devil is one foot higher. I don't know if the solution I can think of at this time will be broken by others.

So Liang Shicheng told Professor flanker his idea,

[Professor, I want to use lidar. In this case, nothing will happen again. The radar should not be cracked.

In addition, since the accident was intentional, are there any clues, or how to find clues, who is targeting me and my competitors?]

Professor flanker sighed in front of the screen and began to type slowly,

[your competitors? It's hard to judge. Let me tell a real story first.

For waymo, who specializes in taxi business in the field of driverless driving, their car accidents emerge one after another, and many of them are man-made. There are always some drivers who deliberately hit the waymo test car and suddenly slow down in front of the waymo car. Waymo was not able to brake at all, resulting in a car accident.

For driverless, once popularized, many companies will lose their jobs.

However, these are low-end manual attacks, which should be responsible in the end.

However, some folk hackers have extended technical assistance to them. The hacker's method is more clever and depends on technology.

There are many other ways besides what you have encountered this time······

There is a special word to describe this kind of behavior of hackers

Then Professor flanker sent another picture and added,

[it's said that face recognition system has been popularized in your country. Now I'll give you a good thing. As long as you print this picture on your clothes, you don't need to cover it all, just a little.

I found this picture from the hacker community. There are many kinds of similar pictures.

The face recognition system can't recognize you. In other words, in its eyes, you are not a person, but something else.

But this picture itself has no meaning in the eyes of outsiders, but it may be other pictures in the eyes of artificial intelligence.

Someone on the street can deliberately put such similar pictures to interfere with cars. This phenomenon is very common. There are special people to study this kind of problem.

As for lidar, I can tell you clearly that although the principle of cracking is different, some people have successfully cracked it.

I noticed some special bumps on the outer surface of the truck. I guess it was used to deal with lidar.

As for who did it, I can only say that there is this technology and research direction in the world.

Now that weapons already exist, anyone can use them, either other drivers or commercial competitors.

And maybe private drivers teach themselves hacker technology, or some companies hire hackers.

I heard that your electric vehicle company is now a dark horse in the industry and can threaten the position of Tesla, the industry leader.

As for who it is, we can only find the answer on that truck.]

[but what I want to emphasize is that this is commercial competition. As long as it doesn't break the law, what to do and how much it costs, or as long as the means are so clever that the police can't understand, it doesn't break the law.

It is normal for Internet companies to use technical means to pollute their opponents' data.

It's better to build your own defense system than speculate about the murderer. I have limited ability in this aspect and can't teach you more knowledge, but I can recommend someone to you.

But I can't guarantee that this person will support you with his heart only by interest.

In other words, you have to pay him to hire him full-time, and with his character, you have to provide him with enough research conditions.]

Professor flanker's attitude was sincere and modest. At the other end of the computer, the professor lay in his chair and recalled his old friends and their memories.

Liang Shicheng collected this picture and then replied,

Well, thank you very much. I understand what you mean.

I happen to have this idea. My company is expanding its recruitment and is recruiting at a high salary.]

Professor flanker didn't expect Liang Shicheng to agree so simply. In his eyes, he just did his best to Liang Shicheng,

[then, please.

This man is a good friend of mine. He may be a difficult person with a strange temper.

If he offends you because of his character, I'll compensate you first.

But I can assure you that he is a talented man, a man buried in the world.]

After reading this reply, Liang Shicheng felt a burst of ecstasy.
