I'm back in 1990

Chapter 1135: Forgetting to Eat and Sleep

After returning to his room, Huang Zeji considered it for a moment and decided that he still needed to purchase some more equipment.

He made a list. He already has a 4K professional monitor and a high-precision 3D scanner, but that's not enough. He's currently using a high-spec personal computer as a temporary server workstation, which is just enough. To get better results and save time, he'll need to buy a top-of-the-line professional server workstation.

In addition, one 4K monitor is not enough, so we need to add two more. We also need to buy several of the latest mobile phones and cameras, as well as a lens stabilization test turntable. All of this adds up to several hundred thousand yuan.

He doesn't have much money left now, probably only two or three hundred thousand, which is far from enough to buy these experimental equipment, not to mention that outsourcing the modules will cost even more.

So, taking advantage of his father's supportive attitude tonight, he decided to strike while the iron was hot.

His father must be drinking tea in the tea room on the first floor right now, so he went downstairs.

He knocked on the door: "Dad!"

Seeing his son come to find him on his own initiative was very surprising to Huang Xiaochuan. He knew his son's temperament better than anyone, so his son must have something to say.

So he asked, "Looking for me?"

"Hmm!" Huang Zeji nodded and walked into the tea room.

Huang Xiaochuan casually pointed to the person opposite him: "Sit down and talk."

Without any preamble, Huang Zeji placed a list he had compiled in front of his father: "Dad, I want to buy some experimental equipment."

Huang Xiaochuan put down his teacup, picked up the paper and started reading. It listed all the professional equipment, including cell phones, but noted that cell phones were also equipment needed for the experiment.

After confirming the items on the list, Huang Xiaochuan immediately agreed: "Okay, I'll arrange for someone to get these for you tomorrow."

Seeing his father agree so readily, Huang Zeji was overjoyed: "Thank you, Dad!"

"Why are you being so polite with me? Do you have some time? Have some tea with me?" Huang Xiaochuan turned around to get a teacup for his son.

But Huang Zeji wanted to go back to his room: "Dad, I have something to do. I'll keep you company next time!"

Huang Xiaochuan knew his son was busy, so he didn't insist. He instructed, "No staying up late. You must turn off the lights and go to bed before 11:30 p.m. I'll check later."

Huang Zeji nodded and said, "Understood!" Then he went upstairs.

The next day, Huang Xiaochuan brought his son to the office, where the legal counsel talked with him for the entire day.

Over the next three days, Huang Zeji provided the necessary materials with the assistance and requirements of the legal department.

Patent application is a rather complicated process, but it's not a problem for professionals, and everything is proceeding smoothly.

Furthermore, the legal representative in charge of this matter reported to Huang Xiaochuan separately, saying that these patents have extremely high commercial value, which made Huang Xiaochuan very happy.

During this period, all the equipment Huang Zeji needed was moved into his room. For this reason, the power company also increased the power capacity of the old house, otherwise the power switch in the house would not be able to handle it.

Huang Ruiying was curious when her brother's room suddenly had a lot of new equipment, so she went to take a look.

Aside from cell phones and cameras, she didn't understand what any of the other devices did.

With the equipment in place, and the legal department handling the patent matters, Huang Zeji planned to build a complete code repository before the start of the school year.

Therefore, he continued to look for suitable programmers on the subcontracting platform, and the team of programmers who regularly receive orders from him has now expanded to more than 20 people.

Leveraging his existing technical expertise, he served as both a product architect and a code reviewer.

Every night, he would focus on processing the code submitted by the subcontractors, running tests, finding bugs, providing suggestions for improvement, and then rejecting any code that did not meet the requirements.

Besides his computer, there was also a bookshelf next to his desk filled with various professional books, making it easy for him to grab them at any time.

In early August, Huang Zeji suddenly had an inspiration while testing a new image stabilization algorithm one evening.

He had been struggling with using gyroscope data to compensate for lens shake, but the results were inconsistent, with the problem being more severe in high-frequency shaking scenarios.

While testing, he looked at a test curve and suddenly remembered a paper on inertial navigation that he had read before. The paper assumed that if the gyroscope data of multiple consecutive frames were regarded as a time series and Kalman filtering was used for prediction and correction, theoretically the anti-shake accuracy could be greatly improved.

He got right to work, sat up straight, and started typing on the keyboard. By the next morning, he had derived several pages of mathematical formulas and written over two hundred lines of core algorithm code. Hard work pays off; after testing, his newly written program ran successfully.

He was wide awake and threw in a set of yacht photos his sister had brought back, running them over again.

Loading, processing, and outputting.

After waiting for more than an hour, the results came out.

The ghostly images originally caused by the ship's swaying have been greatly reduced. Although it has not yet fully met Huang Zeji's requirements, it is already many times better than most mobile phone algorithms on the market.

He encrypted the algorithm and also set up some anti-piracy traps within it, which was his own method of preventing piracy.

After reviewing the technical details, this new algorithm will also apply for multiple patents.

Seeing that her son hadn't come downstairs for breakfast, Yu Xiang, feeling a little worried, went upstairs to look for him herself.

The moment the door was pushed open, she was startled. It had only been a few days! So many new appliances had appeared in the room. Was this still a bedroom?

Where the original desk was, two long tables have been added, with various equipment and parts placed on them. The original TV wall is covered with sticky notes, and several disassembled camera circuit boards are scattered on the desk.

Huang Zeji was busy in front of the computer, glancing at the screen every now and then.

It wasn't one screen, but three: one showing code compilation, one showing complex mathematical formula derivations, and the other showing a PDF, the contents of which were unclear.

"Xiaodong!" Yu Xiang called out to her son.

"Mom?" Huang Zeji turned around after hearing the voice.

Yu Xiang walked to her son's side: "What are you busy with? Why don't you come downstairs for breakfast?"

"Hehe, I forgot, I'll go in a bit." Huang Zeji then realized that his stomach was growling.

Yu Xiang pretended to be displeased and said, "You can like tinkering with computers and cameras, but you have to eat on time, or I'll throw all these things out."

"Okay, I understand. I'll go downstairs now," Huang Zeji said as he saved the computer program.
