Xueba's Black Technology Simulator

Chapter 42 Shocking Everyone (Read More)

Lu Xiao had only watched it for over an hour, and then Secretary Fang and everyone called Lu Xiao out to eat hot pot.

Fortunately, all the information Lu Xiao has read in the simulator.

New technologies are being simulated.

Everyone went to a nearby hot pot restaurant to eat hot pot together.

Secretary Fang thought that Lu Xiao didn't see anything at all, so he smiled relaxedly and said, "Can student Lu eat spicy food?"

Northerners are generally not very good at spicy food, and Lu Xiao is the same, he is very repulsed by spicy food.

I usually don't eat chili at home, so I shook my head and said, "I can't eat spicy food. I heard that there is a mandarin duck pot. You can try this."

"Hahaha, red pot is the only way to eat hot pot." Zhang Bing said.

Other researchers also have northerners, but they have long been accustomed to Sichuan cuisine, after all, most of Sichuan cuisine has a lot of peppers.

In order to take care of Lu Xiao, everyone still ordered the mandarin duck pot.

There are 8 people in total, Zhang Bing and Secretary Fang are slightly older, and the others are all under 30 years old.

However, they all had high academic qualifications. Before dinner, everyone introduced each other, and Lu Xiao realized that most of them had graduated from master's degrees, and some had PhD degrees. Lu Xiao was still a high school student.

Everyone hasn't communicated with Lu Xiao in depth yet, and they all treat him like a little brother.

Fortunately, Lu Xiao also has a lot of things that everyone is interested in, such as the experience of participating in the IMO last time, and how he came up with the new algorithm.

After getting in touch, everyone found that Lu Xiao's knowledge base was far beyond that of high school students, even better than some of the graduate students.

"Lu Xiao, have you finished your university courses by yourself? Your knowledge reserve is stronger than mine." A researcher said.

"It's okay, I read a lot of books, and I have accumulated in all aspects." Lu Xiao smiled.

Lu Xiao hasn't said that he can speak three languages, plus other talents.

During the meal, Lu Xiao also asked about some materials he had read before, mainly discussing the radar issue.

He had to distract himself so that he would not be disturbed by the noise in his ears. He is much better now, and he didn't wear headphones when he met everyone today.

However, he feels that he can only control it for five or six hours, and he still needs to wear headphones when he returns to the hotel later.

When Lu Xiao was chatting, he asked everyone about the technical information of the radar. Although there was a lot of information, he had read a lot before, but because what Lu Xiao is simulating is a new radar data processing method, he can get more information from everyone. will speed up the simulation.

"There are many kinds of radars now, such as pulse radar, continuous wave radar, pulse compression radar, frequency agility radar, sonar radar, etc. This time, we also installed many kinds of radars on the UAV we designed."

"However, our main research is not radar. This is Shen Fei's work. Now we are going to use the technical solution you gave to improve it and use it on large drones to remotely identify faces and lock targets." Zhang Bing Said.

Everyone drank some beer and chatted slowly.

From Lu Xiao's chat, everyone also knew that Lu Xiao should not be underestimated, and now they finally discussed specific technical issues with Lu Xiao.

"We are considering whether to use some optical lenses to collect data, and then undergo special processing to recognize relatively small objects or even human faces, such as using other optical scans." A researcher said.

At present, in addition to the normal lens, there are infrared shooting, ultraviolet shooting and so on.

The goal of everyone is to be able to recognize human-sized objects at least 1 km away, and to advance a little bit, it is best to be able to recognize human faces.

But also under high-speed flight.

When the drone is far away, even if it flies faster, it can still take videos or photos. In theory, it can be done, but it must solve the countless difficulties it faces.

After hearing a lot from everyone, Lu Xiao said, "When shooting, as long as the drone slows down and is equipped with a longer lens in cruise mode, it should be able to get clear photos, right?"

Now Lu Xiao still doesn't know what's going on with the technology he simulated, so he can only speak casually.

It is likely that his perception itself was wrong.

"Our current UAV is used for long-range long-range reconnaissance and attack aircraft. It carries missiles, but it uses laser guidance. It is very large and cannot be too close to the ground. The target below is identified."

Seeing that Lu Xiao didn't understand, Zhang Bing re-described: "For example, if there is a troop on the ground, and a reconnaissance plane finds the headquarters, we know the size and appearance of the commander. Complete the lock, then we are considered successful."

"The most difficult part is that it is impossible for the commander to look at the sky exactly. If it is captured by our drone, the role of optical photography is extremely limited."

Now Lu Xiao understood how difficult it was.

In the past, the drone he designed automatically tracked, and a drone was placed in front of him to shoot at his face.

Data transmission to drones in the sky.

Rongfei's drone laboratory wants to use an overhead drone to take pictures of people's faces on the ground and identify who the person is.

For a long time, everyone didn't concentrate on eating.

Instead, they talk about various technical issues. After the engineers enter the state, eating has become less important.

Seeing this, Secretary Fang specifically asked the waiter not to approach their private room.

Outsiders can't hear the discussion inside.

The time lasted for two or three hours before Secretary Fang couldn't help reminding: "Why don't we talk next time, and we'll stop here for dinner today. Lu Xiaogang needs to take a good rest when he comes to Rongcheng."

Lu Xiao naturally refused to agree, and he waited for about an hour before the simulation was completed and it was a blockbuster in front of everyone.

He couldn't get in the conversation a lot of the time just now, and he didn't make casual comments.

"Brother Fang, don't worry. I'm not tired at all. Everyone is talking about excitement. Drinking some wine seems to make you more inspired." Lu Xiao smiled.

Then he invited everyone to have a drink and let everyone continue the discussion.

Others did encounter some algorithm problems in their previous research, so they just took advantage of this dinner to ask Lu Xiao.

After another hour, Lu Xiao heard the sound of the simulation completed in his mind.

Immediately lifted the spirits.

Immediately check what the technical solution is, much earlier than the expected 5 hours.

It seems that the audience just discussed technology and accelerated the simulation speed.

After Lu Xiao checked the plan, he was shocked. He knew that another epoch-making black technology was about to be born!
Lu Xiao can quickly digest and absorb the simulated plan.

After getting acquainted with each other, Lu Xiao clapped his hands to attract everyone's attention.

Everyone looked at the little brother from the north in doubt. At first, Lu Xiao participated in the discussion on the design of automatic tracking of drones, but then he was completely silent.

Everyone thought that Lu Xiao didn't understand combat drones at all, and he didn't force it.

A few researchers were afraid of Lu Xiao's embarrassment, so they specially picked a few algorithm questions to ask Lu Xiao.

Zhang Bing also looked at Lu Xiao suspiciously. He didn't know what he was going to say. He really ignored Lu Xiao today. He originally welcomed him to Rongcheng.

As a result, after everyone ate, drank and chatted, it became a technical discussion meeting for engineers.

"I'm sorry, Lu Xiao and we, a group of technical people, can't finish the discussion. Have you eaten? Let's take you back to the hotel first." Zhang Bing said.

He thought that Lu Xiao was emotional because of being left out, so he hurriedly sent Lu Xiao back to the hotel, and everyone had another meeting to record some inspirations of the design plans discussed just now.

"No, Brother Zhang, I've heard everyone discuss it for so long, and I have an idea. If there is no accident, the effect you want can be perfectly achieved." Lu Xiao smiled.

"what?"

"How is it possible, Lu Xiao, you don't understand our equipment."

"Yeah, Lu Xiao, what do you think? You have a lot of ideas. Actually, you have a good idea, but it's hard to realize."

Everyone immediately started talking, and they didn't believe that Lu Xiao had come up with a solution.

They are a group of top students who have been studying this technical solution for a long time.

Tonight, it was even discussed that it is unnecessary to pursue face tracking, because it is impossible to achieve at all, so I simply gave up my previous ideas.

Don't use Shendiao drones as the basic design, but use countless small drones to form a drone array.

Released to shoot people in parallel, as long as the drone is small enough, it can go to various places.

Command posts on the battlefield can also be invaded.

The final goal is to play a positioning role, lock the target and then guide the Shendiao UAV.

In fact, it is equivalent to using the Shendiao UAV as the mother machine, carrying dozens of small UAVs, and releasing the small UAVs from high altitude to the ground when they see places that need to be investigated.

Let the small UAV advance horizontally in all directions, and transmit the data to the Shendiao UAV in real time.

Everyone thinks this plan is good. The Shendiao UAV is so big that it can carry countless small UAVs.

These small drones can be upgraded in the future, and the final form may be a fly, a mosquito, or a mouse or a cockroach crawling on the ground.

Since the specific face on the ground cannot be recognized at high altitude.

Then follow Lu Xiao's original design idea and use two ports.

In the past, Lu Xiao's high-altitude port was used for shooting, but now the high-altitude port is used for launching missiles.

The ground port can be divided into parts, and there are countless clones, and the target person can be searched in a carpet style.

Everyone couldn't think of any better solution than this one.

Seeing that everyone didn't believe it, Lu Xiao explained: "My plan involves some special algorithms that can effectively process radar information. Isn't the current radar divided into sonar and electromagnetic wave radar? One is horizontal electromagnetic waves and the other is vertical sound waves."

"Although the speed of electromagnetic waves is 100 million times that of sonar waves, the comparison is not obvious in short-distance reconnaissance, so it is no problem to use sonar waves."

"It's hard to describe the specific implementation method here, so let me just talk about the effect."

Everyone listened attentively. After all, everyone's previous plans were actually based on optical camera data processing.

By taking pictures, let the drone recognize the face.

Now Lu Xiao said, can the face be recognized in the form of radar?

That sounds unlikely.

But after a night of contact, everyone also felt that Lu Xiao was still a relatively stable person and would not make such jokes.

"When the sonar wave encounters an object, it will feed back information to the radar. Normally, when encountering a person, we at most know that there is someone standing there, right?" Lu Xiao asked.

Everyone nodded one after another. In fact, most of the sonar radars are used in water.

For example, detecting reefs, icebergs, shipwrecks, and deep-sea fish. Of course, you can actually detect people when you meet them.

Why are most of them used in water, because electromagnetic waves don't conduct well in water, and it just so happens that sound waves travel very fast in water.

In the air, sonar faces all kinds of noise interference, and the propagation speed of air is 300 meters per second, while the transmission of electromagnetic waves is 30 kilometers per second. The difference is huge!

This is also the reason why everyone's first reaction in sonar is something in the water.

But now sonar actually plays a big role on land, that is, it is used in the field of robotics and unmanned driving.

Think about it because of the special sonar system of bats, even if thousands of bats are in the cave, no matter how dark the environment is, they will not collide with each other, let alone hit the mountain wall.

You will know the potential of sonar.

As long as the data can be processed, sonar can perfectly read the true shape of the object, but the way humans use "data" is too rough.

Even if sonar is used on land, the data generated by the complex environment on the ground has too much interference and cannot be processed at all.

There are fewer objects in the water that can reflect echoes, and there is less mutual interference, so it is naturally easy to deal with.

When Lu Xiao proposed to use sonar, everyone's first reaction was that it couldn't be used.

"No, the sonar interferes too much. You must know that sound waves will reflect each other in any environment, just like there are countless islands on the water surface. When waves hit the past, the water waves will become extremely messy." Zhang Bing shook his head and said.

Lu Xiao already has a detailed technical solution, and with his current level of mathematics and informatics, it is easy to see how powerful the algorithm obtained this time is.

Let’s take an island on the water surface as an example. If the water waves sway, a very complex image will be formed. If these images are processed well, the shape of the island in contact with the water surface can be known.

Because of islands of different shapes, the feedback ripples are different.

Lu Xiao feels that the sound wave solution simulated this time is also related to the crop circle when he first came into contact with it.

The simulation speed is so fast, it must be the data that life simulation came into contact with, which was used in this simulation.

In order to make crop circles in the future, as long as the sonic radar is improved, sonic weapons may be made.

Of course, Lu Xiao hasn't simulated a plan yet, and it will take some time.

He is going to help the UAV laboratory solve the sonic face detection technology first, and then go up to the mountain to rest and wait for the crop circle sonic weapon simulation to end.

"The biggest problem with using sound waves to obtain information on the ground is interference, but the best place is also the complex data information fed back through sound waves. Since bats can handle complex data in caves, and there are countless bats flying around to avoid collisions, If we find a way, we can also use sound waves to determine what a person looks like."

"Not only can we determine the appearance of a person, but we can also determine any shape on the ground. There is a small pit on the ground, and the structure of an ant hole can be identified!"

"I already have an inspiration, so why not go to the laboratory and let me verify my idea." Lu Xiao said.

Everyone opened their mouths wide in shock, and they can even recognize ant holes. Is this against the sky?
Moreover, sound waves recognize faces. I have never heard that sound waves can be processed in such detail before.

Sonar in water actually detects objects in certain places, and then marks a light spot.

Does Lu Xiao want to use sound waves to achieve re-modeling at the software level?
According to this idea, Lu Xiao should be developing a new radar. As long as the radar is placed on the ground, the environment in which sound waves can transmit information can be completely simulated!

After all, sound waves are not related to the water surface and the edge of the island.

Sound waves travel in all directions, up and down at the same time.

Zhang Bing blushed a little from drinking beer, but at this moment he was very interested, he patted the table and said, "Okay, let's go to the laboratory and see how Lu Xiao does it, everyone cooperate with me!"

　The author is not a science student, many technologies are fantasy, please don't take it seriously.It may be possible for sonar to recognize faces, but in reality it should not be.
