Chapter 547 Xie Yuanxun Was Hit Hard
Xie Yuanxun narrowed his eyes slightly and stared straight at Song He opposite.
Song He took his time, chewed up the meat in his mouth, swallowed it, and started to recite:
"The strapdown inertial navigation system is suitable for special environments without satellite signals. It uses accelerometers and gyroscopes to measure linear motion and angular motion respectively, and then substitutes the initial attitude, initial position, and initial heading for joint calculations..."
"The Kalman filter algorithm, a recursive filtering algorithm estimated with the minimum mean square error, can be applied to inertial navigation systems to make up for the lack of accuracy of system sensors. Noise will appear in the measurements of position, speed, and acceleration at any time, Kalman Mann filtering can be effective…”
"Flight control PID algorithm. The PID controller is a linear controller. In multi-rotor drones, the PID control algorithm can establish proportional, integral, and differential relationships between attitude information and propeller speed..."
Song He speaks very fast, reciting it like a submachine gun, and is even more proficient than reading from a script!
Xie Yuanxun, who was opposite him, was dumbfounded and stared at the computer screen until he finished memorizing the entire page.
"Fuck...fuck..." Xie Yuanxun looked confused, "That's not a word wrong! How the hell is this possible?"
Song He raised his eyebrows proudly and ate the braised pork with chopsticks.
"No! I don't believe it!" Xie Yuanxun struggled, "I can almost recite this page, I'm going to find something difficult!"
"Look for it." Song He looked calm.
"Page 206!" Xie Yuanxun raised his head and stared at him.
"This page is full of formulas. It's hard to read." Song He said, "How about I write the formulas silently for you and summarize them in words?"
"Okay!" Xie Yuanxun nodded, hurriedly found a pen and paper from the side, slapped it on the table and pushed it over.
Song He picked up the pen with his left hand and wrote quickly, while his right hand still held the chopsticks to eat the braised pork. Both hands were extremely flexible, like two octopus tentacles, doing their own thing without affecting each other.
Xie Yuanxun's face looks a bit ugly just by looking at this posture. It's so showy!
He tried to imitate it, but he couldn't imitate it at all. His hands couldn't move at the same time. He forgot to write with chopsticks, and he just poked randomly with the chopsticks when writing.
Soon, half a page of formulas was written. Song He pushed the paper forward and said:
"First, the state prediction value is derived from the state prediction equation. Second, the state optimal estimate is derived from the state update equation. The Kalman gain actually represents the model prediction error and measurement error in the state optimal estimation process. The proportion of..."
"The partial derivative of the Kalman gain matrix can be used to estimate the error equation and predict the covariance matrix..."
Guala Guala memorized it for a long time, and I finished it accurately again!
Xie Yuanxun fell silent and couldn't eat anymore. The corners of his mouth turned down and he fell into deep thought.
[Xie Yuanxun is frightened by your super memory, his resentment value is +700! 】
[Xie Yuanxun was hit hard by your fluent recitation, the resentment value is +900! 】
[Xie Yuanxun has a slight inferiority complex because of you, and his resentment value is +500! 】
"Look around." Song He comforted, "There are always people who are better than you, right? There is always someone with better talent than you."
"That's right." Xie Yuanxun sighed, "Who do you know who is more talented than you?"
"Above me?" Song He smiled, "There's no one above me."
"You really deserve to die!" Xie Yuanxun looked up to the sky and sighed.
After eating, Xie Yuanxun burped, took off the dust from the sheets and quilt, lay down in bed and put on the eye mask.
Song He silently returned to the computer and continued to memorize information.
Suddenly, Xie Yuanxun rolled his blindfold to the top of his head again, turned over and sat up, reopened his laptop, and his face was full of determination that said "I will fight with you."
"Why don't you sleep again?" Song He was surprised.
"No, you are still studying, I can't sleep!" Xie Yuanxun said, "I am not as talented as you, so I can only compete with you in terms of study time! Damn, I never thought that I would have to use the term "stupid bird flies first" in this life!"
"No, don't stay up all night studying with me!" Song He's face changed.
"You can't stand it?" Xie Yuanxun smiled, finding the pleasure of winning a victory.
"No, there are many people who have tried to stay up late to study with me, but ended up miserable in the end! I am a very energetic person, so there is no point in trying to do this with me!" Song He reminded kindly.
"I don't believe this evil!" Xie Yuanxun's glasses widened, "What a coincidence, I also have super energy!"
Song He sighed and continued to look at the computer screen.
What can be done? Good words can't persuade a damn ghost!
…
It's almost dawn.
Xie Yuanxun lay on the table, snoring loudly, and put one hand on his face, not to block the light, but to forcefully open his eyelids with his fingers, but failed.
Song He walked over, grabbed his coat on the bed, shook the sand off, and put it on him.
Go back to the computer, drink some water, and start sprinting for the last 200 pages of information!
The first 800 pages of information are actually laying the foundation for the last 200 pages!
The Tower of Babel has been built to its highest point, and the basement of heaven is within easy reach. It is a success to penetrate it!
The last 200 pages are mainly about writing running programs for Honeycomb.
The program actually used artificial brain programming. Song He was slightly shocked. It seemed that all the cores of the high-precision equipment had been replaced. Brain-imitation programming is an exclusive technology after all. Although it is not 100% confidential, there are technical barriers. High, safer.
Running the program is very important. If the drone is a kind of life, the program is its physiological instinct and thinking mode. These two determine almost everything!
Song He read silently. The program currently used by Honeycomb was already in its 24th edition and had been modified 23 times in a row.
The information listed the detailed procedures for each version, but did not explain the ideas for program changes. It only posted the actual combat data at the end.
Song He had to figure it out on his own, starting from the first line and thinking about why he wrote it this way.
Before reading to the end, he will judge a practical data in his mind, and finally compare it with the data to verify whether his judgment is correct.
But unfortunately...every guess was wildly wrong!
His brows became tighter and tighter. Could it be that his understanding of the information was wrong? Or something went wrong?
Fortunately, this confusion did not last long. After watching 18 versions of the program in a row, a strange sense of transparency emerged. He began to be able to accurately estimate actual combat data, becoming more accurate each time, and his frown gradually relaxed.
[Progress in mathematics detected, from Master Level 37 to Master Level 38! 】
seven in the morning.
"Bang!" Song He put on his laptop and fell down on the bed tiredly.
On the other side, Xie Yuanxun was awakened by the noise and jumped up suddenly.
He was confused for a moment, then suddenly turned his head to look at the window.
There was a layer of yellow dust on the windows, but the sunlight still filtered in and even made the dust sparkle.
Xie Yuanxun looked uncomfortable. He knew that he had failed after all and fell asleep without any hope.
He looked at Song He on the bed opposite. Song He was looking at him quietly with his head turned.
"Have you...finished memorizing it?" Xie Yuanxun was nervous.
