Xueba's Black Technology Simulator

Let the free 3D modeling software to obtain information, Lu Xiao has not yet planned in detail.

Also consider the issue of software confidentiality.

He added a note to the simulation project again, that is: "The software is absolutely encrypted and cannot be cracked."

However, this time the simulation failed, suggesting that Lu Xiao needs to learn the hash algorithm and various other encryption methods.

This algorithm, known to Lu Xiao, can be used to encrypt data.

There are also virtual currencies that seem to use hashing algorithms.

Lu Xiao is going to learn the hash algorithm online.

Encryption is very important. Even the software for Rongfei Group must have powerful encryption measures.

In the next few days, Lu Xiao will write codes every day, and spend time learning various software encryption methods every day.

What symmetric encryption, asymmetric encryption, MD5 encryption are all learning.

Informatics experience is also slowly increasing.

Lu Xiao thought that this month would be spent quietly in code learning, but he did not expect that within a few days, Zhang Bing brought an old man to visit him in the convalescent villa under Xiling Snow Mountain.

Moreover, the two of them brought all kinds of equipment here, so they probably couldn't wait for Lu Xiao to develop it by himself.

After seeing Lu Xiao, Zhang Bing introduced: "This is Peng Fangcun, the chief scientist of the Northwest 5315 Radar Research Institute. Mr. Peng is an expert in radar. Since the last time I heard that you thought of a method that can identify sound wave information, They are asking me about my progress every day."

"No way, I can only bring him over to find you."

"Old Peng is very powerful and should be able to help you."

Peng Fangcun is in his fifties, but his hair is already grey, he wears thick glasses, and he looks like a scholar.

Seeing Lu Xiao wearing earphones, he said apologetically: "Lu Xiao, I also know that you are not in good health, but there is no way, your sound wave interference formula is so attractive. I have done countless experiments these days and found that it can be perfect. It's in line with the law, and I really can't figure out what's going on."

"It just so happens that I have some research on acoustics, so I wanted to come over and see if I could help."

Hearing that he was here to help, Lu Xiao secretly laughed in his heart. He had already planned everything and didn't need help at all.

It seems that it is necessary to introduce his project so that others can have a bottom line.

Lu Xiao focused on writing codes these days, but he was also strengthening his control over his ears. He took off the earphones, nodded and said, "Hi Mr. Peng, the software has not been made yet, but since you are here, I can tell you about it. In principle, I have completed all the designs in my brain, and now I am writing things out.”

It is not completely useless for an expert like Mr. Peng to come, and the sonic imaging project does not need help.

Other projects do.

It happened that he was simulating the "Crop Circle" scheme, and encountered some difficulties. The progress bar was stuck at 50%, which has not changed much these days.

For a while, I don't know which knowledge reserves to improve, so as to promote the simulation of the "Crop Circles" project.

Lu Xiao was going to conquer the two of them and let them realize that the project was completely fine. If they really wanted to help, they could focus on his other project.

Lu Xiao took the two of them to the computer where the code was written.

The screen is full of codes. Lu Xiao doesn't use a programming platform at all. He is afraid that his code will be leaked. He writes it in Notepad. After writing the program, he doesn't need to go to verify it.

Currently still writing the main framework of the software.

Lu Xiao's code writing method shocked the two of them. It is really special to write code in Notepad.

Ignoring the shocked two, Lu Xiao turned on the computer's built-in drawing function, ready to demonstrate the project process.

The software is too complicated, with millions of characters, even Zhang Bing and the others might not be able to understand it.

Most of the code is still in Lu Xiao's mind.

In the future, Lu Xiao will definitely develop a brain-computer output device, which can directly output the information in his mind, so that there is no need to use both hands to code codes.

These days, Lu Xiao's hands are almost swollen, and the code is only half written.

Writing a software by one person is really not that simple.

Take computer systems as an example.

Windows 7 is about 50,000,000 lines of code.

When Windows 7 was developed, there were 23 teams, each with about 40 people, or nearly 1,000 people.

Windows Vista is about 50,000,000 lines of code, and it is estimated that more than 100 million lines of code are corrected.

There are over a thousand builds, each of which has been tested.

There are more than tens of thousands of regular workers, contract workers and temporary workers who have contributed to it.

So many people developed it for several years before they made a computer operating system.

And this is calculated by lines, which may not be very intuitive. The usual A4 paper is printed in the Consolas font by default, and a piece of A4 paper can only write 44 lines.

If he hadn't developed a device to read brain information, Lu Xiao would never type the system code by hand.

Writing about a hundred thousand lines of code this time has exhausted him.

Lu Xiao drew the software flow chart and introduced: "This is my software design plan. The whole project is divided into four parts. The first part is the sonar equipment, which is responsible for transmitting ultrasonic waves and receiving ultrasonic waves. Here I wrote a plug-in to convert the complex The acoustic wave data is converted into a two-dimensional data representation using the acoustic wave interference formula."

"The second part is data processing. It is not perfect at the beginning. The amount of data is huge. Ordinary computers can't calculate it at all. It is possible to calculate it with a server. Of course, supercomputing is better. This step is mainly to filter out the target. "

"For example, if our target is a tank, then we can filter the target data of the tank. The sound wave data can be regarded as a curtain covering the entire land. We need to cut off the curtain of the tank and perform separate calculations."

"If it is a person, in a crowded environment, the data of countless people will appear. At this time, we need to screen the specific identification targets we need, which can be screened from various aspects such as body shape, location, and reference objects."

"The third part, which is also the most important step of the whole solution, is to automatically convert the data into a 3D model without any color, which can be automatically modeled in this step."

"The last step is to get the specific coordinates and complete the character locking. You must know that even if the sound wave is a maze, it can actually transmit and reflect the sound wave continuously. In the end, we can also obtain the modeling graphics of the maze."

After the introduction, Lu Xiao looked at the two experts who were slightly sluggish, and asked, "Do you understand?"

Zhang Bing is at least at the level of a university professor. After listening to it, it's not that he didn't understand it, but he didn't understand it at all.

Can sound waves feed back such complex data?

The principle is understandable. At present, B-ultrasound for babies is actually to use ultrasound to stick to the stomach to see the baby's position, appearance, whether there are defects, etc. in the stomach.

But that is to send out the ultrasonic receiving signal close to the stomach.

Lu Xiao's design is beyond Zhang Bing's comprehension.

Many people have seen audio files, which are up and down lines, but with B-ultrasound or sonar, the sound information obtained is not simply up and down lines.

B-ultrasound 3D ultrasound imaging means that the B-ultrasound probe continuously emits ultrasound waves, receives echoes to form 2-dimensional data, and finally synthesizes countless 2-dimensional images to see the 3D image of the baby in the stomach.

Even if Lu Xiao didn't invent this algorithm and software, maybe many years later, humans can still invent devices that emit ultrasonic waves over a wide area and clearly scan human faces.

As computers become more and more powerful, they can quickly process more complex data information. Even without algorithms, images can be obtained by hard cracking.

Now Lu Xiao's formula algorithm plays a very important role.

Peng Fangcun understood it completely, and he felt the power of Lu Xiao. Among these four steps, each step probably contains countless algorithms.

How to simplify the data, superimpose multiple two-dimensional images of sound to form a three-dimensional image, and how to automatically model and filter target data are all technical difficulties.

From the looks of it now, Lu Xiao has completely solved the problem.

Just get the thoughts out of your brain.

Ridiculous that he even wanted to help!

When he came here, he thought that he was an academician-level expert and could help Lu Xiao solve some technical problems, but judging from Lu Xiao's performance, he didn't need to intervene at all.

It's hard to imagine that Lu Xiao is still a high school student!

Are all high school students now so powerful?

If Peng Fangcun had read the novel, he would probably have said that famous quote, it was so terrifying!
