With Pan Wenjun making the decision, and the two professors of the project team agreeing to overturn the previous research direction, the specific implementation efficiency is naturally very fast.

After the meeting, Pan Wenjun reassigned tasks to everyone and began to follow Xu Yun's design plan.

Among them, Xu Yun is naturally responsible for the core content, improving the algorithm to solve the sidelobe problem and optical phased array.

Originally, everyone was still a little incredulous, marveling at Xu Yun's terrifying learning talent.

It wasn't until this plan was actually implemented that they could fully understand the feelings of Academician Pan and the two professors.

Not to mention that the previous research direction is just a bit eyebrow-raising.

Even if you finish most of it, you will not hesitate to choose to overturn it and start over.

Because the gap between the two is too big.

If their initial research direction can barely keep up with the industry, then Xu Yun's design scheme may be ahead of the world.

The value of possession cannot be measured.

The key is to study according to Xu Yun's design plan, and the problems that plague them are solved, and the progress speed of the project has also been greatly improved.

However, Tang Kang and Qin Hangfei accepted it the fastest, and they almost turned into curious babies in the back.

I have to ask Xu Yun about relevant questions every day.

After all, they knew very well that Xu Yun couldn't stay in the laboratory all the time, and it would be difficult to return to Jingzhou to meet again, and now that such a good time must make full use of learning more advanced technology from Xu Yun, and you must know that learning is your own thing.

In this regard, Xu Yun did not refuse to come, and almost let himself experience the experience of bringing the tutor to the students in advance.

The main Tang Kang and Qin Hangfei are all project members, and the more thoroughly they understand, the faster the progress will be.

In short, it's all about completing tasks and getting rewards.

In addition, it is worth mentioning that although Xu Yun's design scheme is very complete and cannot find loopholes, it is still difficult to study it specifically, such as the chips and precision processing technology required by LiDAR.

Fortunately, with the joint efforts of everyone, the laboratory finally produced a piece of equipment in July.

And immediately start the actual test experiment.

……

……

"The weather is not very good today, will it affect our test data?"

July 3, 2018, Imperial Capital University, on the outer road of the campus.

Tang Kang sat in the passenger seat of the test vehicle, looked at the moderate rain outside through the window, and turned his head to express his concern to Xu Yun and Professor Wang in the back row.

The solid-state lidar they are researching is mainly used in vehicles, drones, robots and other fields.

Since its performance is tested, it is undoubtedly the most suitable way to choose to install it on the car and actually drive it.

However, lidar uses laser as a signal source, which causes scattering by transmitting pulses to the target, and the light wave is reflected to the receiver and then the data distance to the target is obtained according to the principle of ranging.

At the same time, the target will be scanned to obtain all the target point data.

This data is used for imaging processing to obtain accurate three-dimensional stereoscopic images.

With this principle as a premise, there will be a difference in the distance reflected by different target materials.

Not to mention the special weather now.

There is no doubt that there will be an impact on the test data of the lidar.

Unable to exert full effectiveness.

"Lidar has extremely severe weather in its practical application, and we definitely have to take it into account in our testing."

"Don't you have faith?"

Xu Yun took Tang Kang's words and replied with a smile.

The test time that has already been set may be delayed for a few more days if it is changed in the middle of the test.

Now that it has entered July, according to the progress of the advanced mission displayed on the panel, he is afraid that it will be completely closed by the end of this month, and he definitely does not want to continue to wait.

After consulting with Pan Wenjun, it was decided to continue the rainy day test according to the set time.

"Xu Yun said a lot."

"Only when our lidar can withstand bad weather can it be regarded as a qualified product and live up to the country's expectations of us." Professor Wang recognized Xu Yun's concept, and replied to Tang Kang with a smile on his face: "Our product adopts Xu Yun's design scheme, which is composed of tens of thousands of laser receivers, and I believe that there is no problem even in extreme environments. ”

"Professor Wang is right, it seems that my worries are superfluous." Tang Kang put his hand on his head with some embarrassment.

Professor Wang didn't say anything about this, and immediately gave instructions to Qin Hangfei, who was in charge of driving.

"Dumbo."

"Ready to get started."

"Okay professor."

Qin Hangfei nodded in response to this, and then started the car to start the solid-state lidar installed above.

From the outside, the LiDAR is slightly smaller, and the height of the entire cylinder is no more than ten centimeters, because there is no information about the surface used for testing.

Soon, as the vehicle started and merged into the main road, Xu Yun and Tang Kang each held their laptops to check the three-dimensional images fed back by the radar.

With the help of software and algorithms, the target points reflected to the receiver are automatically processed to present a stereoscopic image.

It didn't take long for Tang Kang's excited voice to sound in the car.

"The maximum detection distance is three hundred meters."

"The detection distance reaches 90 meters at 10 percent reflectivity."

"The point frequency in single-echo mode is 198,000 points per second."

"This has exceeded the new test data of Veloga, a leading overseas lidar giant brand!"

Compared with Tang Kang, who was very excited, Xu Yun sat back, and the corners of his mouth were smiling, and his face remained calm.

Naturally, he also saw the synchronized data.

In fact, it is true that he solved the design plan by overclocking his brain, but there is not much bottom in his mind about the actual data.

Now that there is finally a result, the whole person is completely relaxed.

Velogda has always been a leading giant in lidar, and now they have achieved data catch-up with this domestic solid-state lidar, undoubtedly with domestic advanced lidar, and successfully broke the technical blockade to complete the project.

Then he just had to wait patiently for four months to pass and get the reward for the mission he was longing for.

"The data is better than I expected."

"This data is already very good, and it can be much higher in normal weather." Professor Wang heard Xu Yun's whisper, turned his head and responded with some excitement: "You are the first person to achieve such results in this project, and it will be specially noted in the final report." ”

In the past, they were the old guys who took the lead in the project, and they had to be distracted to take students to answer questions.

This time, I borrowed Xu Yun's light experience to win by lying down, and the mood can be imagined.

Xu Yun knew that what Professor Wang said was right, and if it didn't rain, the test would have been even higher.

However, the current data alone is enough to conclude the problem.

The next time was to ensure the accuracy of the data, and Qin Hangfei drove the car to another road.

Meanwhile.

LiDAR Joint Laboratory.

In the conference room, Pan Wenjun, another professor and the rest of the project team members stared eagerly at the screen in front of them.

Almost as soon as the measured data was synchronized, the expression on his face was instantly replaced by ecstasy.

Cheers rang out from the room.

"The data is out."

"Look."

"It's hard to imagine that the maximum detection distance in a rainy environment is still 300 meters, which is far more than we estimated."

"If it were a normal weather test, the data would have been even better."

"This kind of data is enough for us to reach the international leading level."

"The three-dimensional image constructed by the algorithm is also very clear, and I believe that it will be very popular with users in actual use."

Looking at the data on the screen and everyone's reactions, Pan Wenjun secretly breathed a sigh of relief, and turned his head to look at the professor next to him who was also shocked by the data.

"I said Lao Li, it was the right decision to choose to overturn and start over, right?"

The professor who was called Lao Li seemed to have thought of the previous incident in which he had prevented Pan Wenjun from changing his research direction, and he felt a little embarrassed to respond to this matter at this moment.

"Who would have thought that Xu Yun's design plan was so good, and he should have called people over earlier."

"yes."

"I really envy those old guys at Kyoto." Pan Wenjun nodded and agreed.

Such excellent and gifted students are naturally the goal that every university wants to compete for.

After all, there are also huge benefits for schools.

For example, in the past, Jinghua's Department of Mathematics may have been in the leading position in the country, but since Xu Yun proved Hodge's conjecture and held a global academic report in the Department of Mathematics of Beijing University, the academic status of Beijing University has skyrocketed.

In particular, the Institute of Advanced Mathematics has been established, and I believe that more and more students will be willing to apply for the Department of Mathematics at Kyoto University in the future.

"With Xu Yun's learning speed and qualifications, it is estimated that it will not take long to complete his doctoral studies."

"When the time comes, it is a matter of course to get the title of professor, and even if we can't poach people, it is a good idea to invite them to give lectures a few more times a month."

At this time, Lao Li smiled and gave Pan Wenjun an idea that would benefit the school.

And these words immediately made Pan Wenjun's heart move slightly, and he fell into silence slightly and muttered thoughtfully.

"That's a good idea."

"I'm going to have a good talk with him another day."

"It's better to get the headmaster to come in."

After saying that, he seemed to think of something, and turned his head back to Professor Li again.

"The results of the test are now available, so let's write the final report."

"I don't think it's a problem." Professor Li replied with a smile.

……

Xu Yun and their tests continued until the evening, and only returned to the laboratory after getting very comprehensive test data.

And Xu Yun naturally learned about the final report.

However, in the next few days, while he was patiently waiting for the mission reward, he suddenly received an email from Princeton University, inviting him to Princeton for an academic exchange.

At a previous symposium, he promised Professor Deligne the opportunity to go to Princeton to consult with him.

Now there really is no reason to refuse.

Moreover, being able to communicate with well-known scholars in the field of mathematics is also very helpful for the final proof of his Goldbach conjecture.

Thinking of going directly from Princeton to Geneairo to attend the International Congress of Mathematicians, he finally chose to go in a reply email.
