Yang Chaoxiong didn't have any objection to the elder brother calling Ye Ming over. His mind was full of bugs in the current test card.

"Have you read the project report?"

"Not yet, just went to read the paper."

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

While introducing, Ma Jun paid attention to Ye Ming's expression, seeing that the latter just nodded slightly, and then smiled slightly after showing no timidity.

It seems that the teacher caught the wrong person, at least this guy has confidence.

"Stop talking, hurry up and help me take a look." Yang Chaoxiong stood up and gave up his seat to Ma Jun.

After sitting down, Ma Jun dragged the mouse a few times, and after reading the report, he turned his head and smiled: "You guy, you wrote the algorithm, and the framework and environment are built by you. I can see it. ?”

Yang Chaoxiong looked helpless: "...Brother, I really checked for a long time, and I almost checked the source code with a magnifying glass."

"If it's a teacher, I'll definitely ask you to review the source code with a magnifying glass."

"Brother, tens of thousands of lines of code."

"Then you have to masturbate." Ma Jun chuckled, "Is your algorithm okay?"

"If there is a problem with the algorithm, it can't run, brother." Yang Chaoxiong is obviously unwilling to read the source code, let alone admit that there is a problem with his algorithm, he hesitates: "How about changing to a simulation engine? I suspect that the engine is against me."

"..."

...

Ye Ming was listening to the conversation between the two, and with Ma Jun explaining, he understood what Yang Chaoxiong's mission was.

In the current machine vision perception test of autonomous driving, there are generally three methods. One is based on software engineering methods to build models and input data for simulation tests. One is to use the method of virtual simulation, use the simulation engine to generate three-dimensional 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 actual site for testing.

These three methods have their own advantages and disadvantages. Although the third method is the closest to reality and has reliable data, its disadvantage is obvious, that is, it cannot satisfy the diversity of scenarios.

Therefore, most of the self-driving cars use the second method for testing in order to obtain relatively accurate data and diversity of scenarios.

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

The current problem is that when Yang Chaoxiong runs the test, he can’t pass the trajectory recognition of objects in relative motion—to put it simply, after Yang Chaoxiong’s algorithm runs, someone throws a stone, or the car in front drops a piece of cardboard What, the algorithm can't judge the placement.

And it's not that it can't be judged every time, it's occasionally.

This gets a little crazy.

Hmm... Although Ye Ming didn't know where 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 brother is in charge of?"

Ye Ming was slightly taken aback.

Didn't you come here to make soy sauce?

Still have your own business?

"I probably understand."

"What do you think?" Ma Jun looked at him with a smile, and said meaningfully: "The teacher said, 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... was actually taken aback.

But he immediately shook his head and said with a smile: "I have no idea. Compared with Senior Brother Yang's environmental perception, the machine vision I do is like a child's play house."

——What he said was indeed true.

Although he has been dealing with the trajectories of moving objects for a full month including the holidays, how simple are his trajectories... Whether it is table tennis, bullets, or balls in RC competitions, the parabola counts You will know at a glance, at most, add a speed recognition, anyway, it follows the laws of physics.

But here is the environment perception of automatic driving. When you drive on the road, who knows what will fly over?

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

There will always be something strange and unexpected flying in your face.

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

This difficulty is not comparable.

After hearing this, Yang Chaoxiong's expression relaxed.

That's right.

Doing self-aiming and parameter adjustment again, it is impossible to compare with the environment perception of automatic driving!

Ma Jun also chuckled: "Well, why don't you go with Chaoxiong? I asked the teacher at the beginning, and the teacher also suggested that."

Ye Ming looked at Yang Chaoxiong, and saw that the latter was also looking at him. The two looked at each other, as if they felt that the other party was in a good mood, and then they smiled tacitly and nodded at the same time.

In the next few days, Ye Ming started to go to the preparation hall for the plan at night, and went to the research group to read documents, improve codes, and write papers during the day.

Of course, he will also hang out with Yang Chaoxiong, beat him up, run codes and so on.

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

...

Sitting in the last seat, Ye Ming was almost facing the serious face of Professor Tang Zhigao, which made him realize immediately why when Ma Jun said that the group meeting was going to be held, these brothers and sisters who were usually joking would Instantly changed color.

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

At the group meeting, Professor Tang commented on everyone's reports one by one. Although he didn't scold anyone, it was obvious that he was not very satisfied with the progress of the current project.

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

Then everyone saw that the expression on Professor Tang's face, who was still majestic just now, suddenly softened.

"Ye Ming, what about you?"

"Teacher Tang, I haven't prepared PPT."

"You don't have a scientific research task, what kind of PPT do you use?" Professor Tang Zhigao signaled Ye Ming to sit down directly: "Just talk about your experience in the past few days."

"Well, I have been reading literature and learning machine learning and machine vision with Brother Yang these days."

Tang Zhigao nodded slightly.

After pondering for a moment, he smiled and asked, "How are you doing?"

"Eh..." Ye Ming was at a loss for words for a moment.

How should he answer?

I said that Senior Brother Yang knows how to do it, but I know how to do it?

Even if I can't, I can hang up and force it?

Just when he was about to tell the truth and said that he was working hard, Professor Tang suddenly smiled.

"Chaoxiong will be on a business trip with me for half a month. After studying with him for so many days, you should be almost familiar with him. In the next half month, you will be responsible for taking over Chaoxiong's tasks."

Everyone's eyes "swipe" and stopped on Ye Ming.

First-year undergraduates take over the tasks of Boyi?
