Chapter 54 Identification

Hou Shida did not get angry with Feng Wuji because of the rude behavior of others, and it was obvious that he did not create this situation.

Toyota should be the entrusting party of Fengxin's project, I heard that Fengxin has found someone to solve the technical problems that have been bothering them, and it is normal for Party A to want to meet who is invited.

It's just that Toyota people think that the characters who can be invited by Fengxin should be seniors or prestigious in the industry, and this kind of person's age, temperament and demeanor must not be close to Hou Shida.

The Japanese who came and returned from the bustling were a little blushing, and there was really no need to affect the relationship between Hou Shida and Feng Wuji.

After all, Feng Wuji himself still respects him very much.

Feng Wuji saw that Hou Shida's face was not angry, so he said as he walked: "Mr. Hou, Feng Xin has booked a room for you at the Hilton Hotel, can you go and rest first?" Let's start work tomorrow, what do you think? ”

Hou Shida thought for a while, shook his head and said, "It's okay on the road, I'm feeling in good spirits now, so don't waste time, right?" ”

Just kidding, even if Hou Shida came in a green car, he had to start working quickly! Don't forget, An Ran's family is in Dagang, the sooner you finish your work, the more time you spend with her!

Feng Wuji was stunned for a moment, he didn't expect Hou Shida's work attitude to be so positive, nodded slightly, and then took out the phone and began to arrange.

Hou Shida's luggage was naturally sent to the hotel by Master Liu, outside the passenger exit of the dock, Fengxin sent a black Audi car over, and Hou Shida and Feng Wuji simply went directly to the work site.

To be precise, the work done by Hou Shida should be outsourced. Fengxin is the general contractor of the project, and the entire Toyota production line system is designed and manufactured by it. It's just that there are some problems in the control software part and I can't do it on my own, so I found him.

The work that Hou Shida needs to complete is not complicated, Fengxin gives the program interface, exit and various parameters, and puts forward requirements for the program function, and does not need to introduce the entire system to him.

And Hou Shida has completed this kind of modular work, this program can not only be used on the equipment of Fengxin, but also any other project with similar requirements can also use this module.

This is not uncommon in the international software outsourcing market. The reason why software outsourcing in India is so developed is due to the idea of modularity of software design.

But correspondingly, since it is modular and general, of course, there are some parameters that must be measured and debugged according to the specific conditions of the production line.

Hou Shida's visit to Dagang this time was mainly to debug the fuzzy control module in his hand according to the actual situation of the production line.

Now that we have to start work ahead of schedule, we will of course conduct field measurements at Toyota's production line.

Feng Wuji drove all the way out of Dagang City, and it took more than an hour to arrive at Toyota's Dagang Parts Factory.

This is an electric motor production plant set up by Toyota in China, which is responsible for the motor manufacturing of Toyota vehicles. The motors produced by it are not only supplied to Toyota itself, but even occupy 30% of the domestic automotive motor market.

The car even seems a little quiet in the huge factory area, and there is no loud noise generated by the production work in the ordinary factory area. The layout of the environment and the design of the factory also show the rigorous style of the Japanese.

Feng Wuji's car stopped outside a steel structure factory building about five meters high, and only then did the sound of production equipment running faintly sound.

It wasn't until you walked through a small door into the workshop that the humming sound of machining was fully revealed. In the huge workshop, there are production lines neatly planned. In the roar of the machine, production workers are standing in front of the production line and are constantly busy.

"This is Toyota Electric's welding workshop, and the welding robotic arm control system designed by Fengxin for Fengtian Xinsong Company is currently facing a serious problem......

Feng Wuji led Hou Shida to a separate isolated area, where there was an assembly line and a row of orange robotic arms, apparently a separate test scene set up to cooperate with Fengxin's technological development.

Feng Wuji picked up a part from the end of the assembly line that he didn't know what it was used for, pointed out a piece of weld to him and said, "This is the product we made by welding the robotic arm, you see here, here and here-"

Hou Shida looked over and carefully observed the position pointed out by Feng Wuji, and found that the solder joints in these positions were obviously not very smooth and regular, some because of the special shape of the parts, and some may be caused by accidents.

The only thing these defects have in common is that they can be observed with the naked eye.

"Our robotic arm is also equipped with a visual analysis system, which is a shame to say that this is the technology that Toyota used in the 80s. However, the system can only perform a coherent primary analysis, such as checking the number of products on the production line and roughly judging the type of product. ”

Feng Wuji sighed, shook his head, and said, "In the face of the details on this kind of product, our system is powerless. ”

Speaking of this, he looked at Hou Shida hopefully, hoping that he could really bring him a surprise. If we can break through the yield rate of the welding robotic arm, we can not only greatly reduce the number of inspectors used, but also reduce the cost of products and improve product quality.

If it can really be like the technology used by Hou Shida in the Ba Niang software, the software can accurately identify some special patterns, then the industrial control technology of Fengxin will be at the forefront of the world for the first time!

Hou Shida smiled, he was not sure about the industrial control technology to be honest. The good thing is that he is not asked to design the entire system, but purely outsourced the project, as long as he completes the specific software work.

In fact, this function is very simple, that is, to find the specific position of the welding defect on the image, and then calculate the spatial coordinates of the defect according to the position difference of the double-mirror imaging - that is, similar to the human eyes can carry out spatial positioning, the scenery seen by the two eyes is different, and these differences form the effect of depth of field after being processed by the human brain.

The program that Hou Shida is responsible for is such a "simple" function, as for how to deal with this set of coordinates after passing them to other program modules, that is the work that Fengxin is responsible for.

"Let me take a look, whether you can achieve your requirements will be known after debugging." Hou Shida didn't finish his words, but the work at hand did not stop.

He took out a notebook from his backpack and connected it to a robotic arm under the guidance of Feng Wuji.

Feng Wuji looked at Hou Shida with great interest, ready to learn something from the process of his operation. Even if you don't have access to the source code, you can at least understand the principle of implementation, right?

Not only him, but almost everyone who knows the industry will be interested in how Ba Niang realizes the method of image recognition. Let everyone think about it, and now there is not even a basic idea.

In the eyes of these programmers, the software is simply magical, beyond the scope of the technology they know.

Feng Wuji can see Hou Shida's secret now, how can he not be curious?

I saw Hou Shida neatly turn on the computer, and then connected to the video input program of the robotic arm. Two slightly different images appear on the screen, which is supposed to be a video taken by two lenses of the robotic arm. Being able to display these two images means that his computer has been smoothly connected to the program of the robotic arm.

"Ask the chief engineer to start the production line and put the defective parts that need to be repaired on the workbench."

"Oh, good!"

Feng Wuji quickly selected a part with obvious defects, put it on the workbench, and then operated it on the control panel to start the mechanical arm.

After doing these tasks, he returned to Hou Shida's side with lightning speed, watching intently what he was going to do.

Of course, Hou Shida didn't know what he wanted to do, but he didn't stop it, and directly operated it on his computer.

I saw that he executed a small program that was only about 70 K, and then clicked on the image with the mouse a few times, then nodded and said, "Okay, please trouble the chief engineer of the wind to change another part." ”

Feng Wuji blinked his eyes and asked inexplicably, "Mr. Hou, is this okay?" ”

"Okay, I need to increase the number of samples to be sampled, please put more parts on it."

"Okay, okay."

So he saw that Feng Wuji moved a part here, and then Hou Shida clicked a few times with the mouse on the screen, and then asked him to change another part.

Feng Wuji didn't know what Hou Shida was doing, but Hou Shida was constantly paying attention to a small progress bar at the bottom of the screen. There are two ideas for artificial intelligence in image recognition, one is for people to teach the program how to do it, and the software can learn to recognize a certain pattern after analyzing the behavior of the person. The other is that there is no one to teach the program how to recognize, and the algorithm is used to recognize specific patterns.

What Hou Shida is doing now is actually teaching the program how to identify defective solder joints on parts. As long as the computer collects enough samples, it can establish a model for identifying solder joints.

Then fill in the data of this model into the program that has been written, and the whole work is done.

Just when the progress bar under Hou Shida's computer reached 90%, suddenly a sound of footsteps came from not far away.

Ding Yi stood in front of Hou Shida and Feng Wuji arrogantly, and pretended to cough and said, "Chief Engineer Feng, Mr. Quantian asked me to ask you, can Feng Hyacinth vacate this area?" ”
