Yang Chaoxiong has no opinion on the senior brother calling Ye Ming over, and his mind is now full of problems with the current test card BUG.

"Have you read the project report?"

"Not yet, I just read the paper."

"Well, the topic of our group is the machine vision scheme in the assisted driving system, and the super hero is responsible for the dynamic perception of the environment by the binocular camera."

Ma Jun paid attention to Ye Ming's expression while introducing, and when he saw that the latter only nodded slightly, he smiled slightly after not showing timidity.

It seems that the teacher didn't catch the wrong person, this guy is at least confident.

"Don't talk nonsense, hurry up and help me take a look." Yang Chaoxiong stood up and gave up his seat to Ma Jun.

Ma Jun sat down and dragged the mouse a few times, only looked at the report and then looked back and smiled: "You guy, the algorithm was written by you, and the framework and environment were built by you, can I see a hairy one?" ”

Yang Chaoxiong's face was helpless: "...... Brother, I've really been checking for a long time, and I'm about to check the source code with a magnifying glass. ”

"If it's a teacher, I'll definitely let you take a magnifying glass and go through the source code."

"Big brother, tens of thousands of lines of code."

"That's going to have to be jerked off too." Ma Jun smiled: "You have no problem with the algorithm, right?" ”

"There's a problem with the algorithm and you can't run, brother." Yang Chaoxiong was obviously reluctant to pick up the source code, let alone admit that there was a problem with his algorithm, and hesitated: "Why don't you change the simulation engine?" I suspect the engine is against me. ”

“……”

……

Ye Ming was listening to the conversation between the two, and Ma Jun explained on the side, and understood what Yang Chaoxiong's task was.

At present, there are three ways to test the machine vision perception of autonomous driving, one is based on the method of software engineering, and the model input data is built for simulation testing. One is to use the method of virtual simulation, and use the simulation engine to generate 3D game screen to build a virtual scene to test the algorithm.

The last one is to directly put the machine vision perception system on the car and drive to the real site for testing.

These three methods have their own advantages and disadvantages, although the third one is the closest to reality and the data is reliable, but the disadvantage is obvious, that is, it cannot meet the diversity of scenarios.

Therefore, the vast majority of autonomous driving companies use the second method to conduct tests in order to obtain the relative accuracy of data and the diversity of scenarios.

Yang Chaoxiong also uses the second method - the graphics card of his computer is a 3090Ti.

The current problem is that when Yang Chaoxiong runs the test, he always can't recognize the trajectory of objects that are in relative motion - to put it simply, after Yang Chaoxiong's algorithm runs, people throw a stone, or the car in front of them drops a piece of cardboard or something, and the algorithm can't judge the landing point.

And it's not that you can't judge every time, it's occasionally.

That's kind of crazy.

Well...... Although Ye Ming didn't know what the problem was.

But he knows how to solve the problem.

Rewrite one.

……

This is Ma Jun suddenly looking at Ye Ming: "Ye Ming, do you understand the project that Senior Brother is responsible for?" ”

Ye Ming was slightly stunned.

Didn't you come to make soy sauce?

And your own business?

"I guess I understand."

"What do you think?" Ma Jun looked at him with a smile and said meaningfully: "The teacher said that you are very talented in machine vision. ”

Ma Jun's words made Yang Chaoxiong on the side startled and looked at Ye Ming suddenly.

Ye Ming...... Actually, I was taken aback.

But he immediately shook his head and smiled: "I have no idea, compared to Senior Brother Yang's environmental perception, the machine vision I made is a child's house." ”

- He was right.

Although he had been dealing with the trajectories of moving objects for a whole month, including his vacations, how simple were he...... Whether it's table tennis, bullets, or balls in RC games, just calculate the parabola, at most add speed recognition, anyway, it follows the laws of physics.

But here's the environmental perception of autonomous driving, and if you're driving on the road, who knows what's going to fly over?

Cardboard, stones, bricks, tires, and even aunt towels......

There will always be strange things that you don't expect flying in your face.

What autonomous driving has to do is to identify these things and determine whether they will fly to the face, so as to decide what action the car will take.

The difficulty is no different.

Hearing this, Yang Chaoxiong's face relaxed.

That's right.

If you can do self-aiming and adjust parameters, it is impossible to compare with the environmental perception of autonomous driving!

Ma Jun also smiled: "Well, then you will be in a group with Chaoxiong - I asked the teacher at the beginning, and the teacher also suggested so." ”

Ye Ming looked at Yang Chaoxiong, only to see that the latter also looked at him, the two glanced at each other, as if they felt that each other had the same appetite, and immediately nodded at the same time after a tacit smile.

In the next few days, Ye Ming began to go to the preparation hall at night to prepare for the plan, and during the day to the research group to read the literature, improve the code, and write papers.

Of course, he will also follow Yang Chaoxiong to mess around, play down, run code and so on.

Then, in the second week, he ushered in the first research group meeting in his life.

……

Sitting on the last seat, Ye Ming almost faced Professor Tang Zhigao's serious face, which made him immediately wake up, why when Ma Jun said that he was going to hold a group meeting, these senior brothers and sisters who usually laughed and laughed changed color instantly.

It seems that the rumors of Old Tang's rigorous scholarship are really not legends.

At the group meeting, Professor Tang commented on the content of each person's report one by one, and although he did not curse, he could clearly feel that he was not very satisfied with the progress of the current project.

After the graduate students finished reporting one by one, Professor Tang looked at Ye Ming.

So everyone saw that Professor Tang, who was still majestic just now, suddenly softened the expression on his face.

"Ye Ming, what about you?"

"Mr. Tang, I didn't prepare a PPT."

"You don't have a scientific research task, which PPT do you use?" Professor Tang Zhigao motioned for Ye Ming to sit down directly: "You can talk about your experience in the past few days." ”

"Well, I've been reading literature and learning machine learning and machine vision from Senior Brother Yang for the past few days."

Tang Zhigao nodded slightly.

After a moment of silence, he smiled and asked, "How are you learning?" ”

"Forehead ......" Ye Ming was speechless for a while.

How should he answer?

Say that Senior Brother Yang will actually know how to do it?

Even if I can't, I can open a hanging, and I can't force it?

Just as he was about to panic and say that he was working hard, Professor Tang suddenly smiled.

"Chaoxiong is going to go on a business trip with me for half a month, and you should be almost familiar with him after studying with him for so many days. In the next half month, you will be responsible for taking over the task of Superhero. ”

Everyone's eyes stopped at Ye Ming's body as soon as they "brushed".

A first-year undergraduate student takes over the task of a Ph.D.?
