In Nuoda's workshop, countless injection molding machines are working with the assistance of robotic arms. The air is filled with an indescribable smell and the special sound of mechanical operation.
Ye Ming tightened his mask, and under the leadership of Director Jia, he and Yang Chaoxiong walked into an injection molding machine.
"Our APS system uses An Lei... principle... no need for me to introduce it, right?" Director Jia looked at the two and smiled: "It is actually an industrial scheduling system, which is responsible for integrating ERP (Enterprise Resource Planning)
) and MES (Manufacturing Execution System) and other enterprise production systems, the problem we want to solve this time does not involve this, at best it only involves the production and manufacturing system."
"Well, now the manufacturing industry is indeed moving closer to digitalization and informatization." Yang Chaoxiong casually agreed while walking towards the finished product port of the injection molding machine.
In the middle of the conveyor belt, there is a special machine similar to a machine tool, which consists of a light source and a lens. The pick-up robot arm on the side is continuously taking out a row of automatically fixed plastic spoons from the exit and placing them under the lens for a second.
Finally, the robotic arm puts down the spoon and continues to pick up the items.
The "passed" spoons continue to enter the next process through the conveyor belt.
Looking at this assembly line, Ye Ming... was stunned for a while.
Isn’t it agreed that we specialize in the production of plastic accessories for pure electric vehicles? What is this row of spoons...
"The problem now is recognition preparation, right?" Yang Chaoxiong, unlike Ye Ming, pointed directly at the machine vision system and asked.
"right."
"Now...is there any problem?"
"It's no problem to use it to check spoons. After all, our process for producing these daily products is very mature. Even if there are occasional flaws, it's not a big deal. But it won't work if it is replaced with a slightly more complicated mold. Even if we use AI to learn
No way either.”
"AI learning?" Yang Chaoxiong and Ye Ming looked at each other, looked around in confusion and said, "I haven't seen a PC. Isn't that the AI chip you use here?"
Yang Chaoxiong pointed at the machine vision system that looked a bit silly, bulky and bulky - it looked like a shoulder-mounted camera, and it seemed impossible to install an AI chip.
"Um... there is an identification system here." Director Jia paused as he said it, "Let me demonstrate it to you."
"Then I'll trouble you, Director Jia."
…
…
Three hours later, Director Jia personally drove Yang Chaoxiong and Ye Ming back to the hotel in the city.
The two declined Director Jia's offer to invite them to dinner, went back to the room directly, ordered takeout, and then made a video call to Professor Tang.
"Teacher, do you think we should tell the truth, or what should we say?"
When the two told Professor Tang about the situation, Yang Chaoxiong posed the problem to the teacher.
——In the afternoon, they spent three hours and finally figured out what this system was.
To put it more clearly, someone in the factory probably said "that".
The so-called machine vision is still stuck at the stage of taking pictures and then fuzzy comparison and recognition at least five years ago, let alone complex structures, let alone high precision...
Put it this way, it can only identify whether there are blisters on the surface, whether there is a missing corner, etc.
Of course it's no problem to use it for making tableware.
But it is obviously not possible to use it for high-precision multi-dimensional recognition.
After hearing the reports of the two, Professor Tang, who was at home, was also a little stunned.
He was holding the bowl and spoon, his brows furrowed for a long time.
"It means that the problem cannot be solved by updating the system, right?"
"No, he used a monocular camera. Our solution is a binocular camera, and only a binocular camera can meet the high accuracy." Yang Chaoxiong said and glanced at Ye Ming: "On the way back, Ye Ming mentioned something
I think the solution is very good. It uses a binocular camera to achieve spatial positioning, and then builds a comparison model and appearance based on the algorithm. This has a high error tolerance rate for the robotic arm and the assembly line. Even if there are errors in the position and distance of the product to be detected, there will be no errors.
Impact detection.”
"Hmm..." Professor Tang nodded: "In this case, you should consider the plan first and see if you can come up with a design sketch tonight. If you can give the cost, it would be best... I will ask here again."
When Yang Chaoxiong heard this, he immediately shouted: "Teacher, how can I pay for this?"
"Ask Ye Ming, didn't he himself build a robotic arm and a binocular camera?"
Ye Ming: "..."
After hanging up the call, Yang Chaoxiong looked back at Ye Ming: "You know?"
"I know what the heck, I bought my binocular camera from Taobao for two hundred yuan each. Do you dare to use it?"
Yang Chaoxiong: "...What about the expensive ones?"
"We have them all expensive, ranging from tens of thousands to tens of thousands. Do you want a professional industrial camera?"
Yang Chaoxiong: "..."
The takeaway was delivered, and the two of them ate boiled fish with the air conditioner blowing on.
At this moment, Ye Ming suddenly remembered that Professor Tang seemed to be eating just now, and seemed to be feeding the child with a spoon.
"Senior brother, is Teacher Tang over forty this year?"
"Yeah, what's wrong?"
"Awesome." Ye Ming gave a thumbs up: "Who was he feeding just now? Did he give birth to a second child?"
When Yang Chaoxiong heard this, his expression immediately became strange.
"What's wrong?"
"Don't you know about Old Tang's son?"
"What's the matter?" Ye Ming was confused.
When Yang Chaoxiong saw that Ye Ming really didn't know, he put down his chopsticks and sighed.
"Two years ago, Lao Tang's son had just finished taking the college entrance examination, and he was in a car accident. He couldn't move from the neck down."
"Originally, after the college entrance examination, Old Tang should drive to pick up his son. But Old Tang was taking us with him at the time, so he let his son go home by himself. It's close anyway, right? As a result..."
"Anyway, both the master's wife and his son are complaining about Old Tang."
"And his son did very well in the exam, with scores ranking over 400 in the province...at least he has Hua Wu."
Ye Ming also fell silent after listening.
When someone around you has such misfortune, it makes everyone feel bad.
But after a moment, he immediately looked at Yang Chaoxiong: "What about the teacher's topic for next year?"
Aren't brain-machine wheelchairs specially prepared for people who can't move from the neck down?
Yang Chaoxiong smiled and nodded: "If my son is like this, I will also push a topic to teach my son... Fuck! Bah, bah, bah! My son will definitely be safe!"
Ye Ming: "..."
"Okay, let's not talk about this anymore, let's eat fish and eat fish."
…
After dinner, the two chatted for a while, but in the end they still couldn't sit still, so they each opened their notebooks and started working on a plan.
Professor Tang is right, Ye Ming can do this very quickly. After all, he has experience and ready-made code.
But the cost... Ye Ming really couldn't afford it.
Fortunately, Professor Tang did not force anyone to do anything. When it was close to 11 o'clock, he called the two of them and asked them to go to the factory tomorrow to find out all about the recognition accuracy and bring back some samples.
