After greeting several professors in Beijing, Fu Song greeted Wang Shuhe and Shi Xia again. He turned around and found that Zhao Zhi and Sun Shaozong were in the corner and didn’t know what they were busy with. He hurried over and asked, “What are you two doing? I pretended not to see it when I came here? Are you still polite? Be careful to cut your funds!”

Zhao Zhi smiled and said, "I heard your loud voice a long time ago. Aren't you going to check the progress of Lao Sun and me? Listening to the ears is false, and seeing is true. Our research team must not demonstrate on the spot to block your mouth?"

Fu Song finally saw the pile of things on the ground and said, "You two are so good, you actually moved the workstation."

At this time, Sun Shaozong pressed the workstation power switch, and the screen lit up after a few seconds, "Okay!"

Zhao Zhi immediately said with a quick look: "Lao Sun and I haven't been idle these months, so I'll show you something good."

"What good thing?" Fu Song was not very interested, but could not resist Zhao Zhi's enthusiasm, so he had to stand aside and watch Sun Shaozong operate.

With Sun Shaozong's operation, a bunch of English symbols appeared on the screen. Anyway, Fu Song couldn't understand any of them. He raised his arm to look at his watch and said, "It's so cool, the meeting will begin in fifteen minutes."

Sun Shaozong typing on the keyboard without looking back: "Old Fu, don't worry, it's all right away. Look, this is the main interface of the program. Press F2 to call the coordinate parameters function. The coordinate parameters can be input one by one, or batch input, and then separated by a half-width comma. This is the coordinate parameter conversion function, which can be converted between geographical coordinates and projection coordinates. At present, we have only done the Xi'an 80 coordinate conversion program, and the others can be added later..."

After Sun Shaozong finished his demonstration, Fu Song touched his chin and asked, "Old Sun, did you write this thing?"

Sun Shaozong said: "I wrote the main program, and Lao Zhao is responsible for projection-related functional modules."

Fu Song smashed his mouth and said, "Old Zhao, why do you look more and more like Esri's ArcInfo? You two won't copy them, right?"

Zhao Zhi's face turned red and he coughed, "What you said is, please refer to it! Well, refer to it!"

Sun Shaozong scratched his hair and said, "At the beginning, Lao Zhao and I didn't think so much. We wrote this program to save trouble when digitizing it. Then we slowly added functional modules to it, and finally it turned out like this."

Fu Song asked: "How is it compared to ArcInfo?"

Sun Shaozong smiled bitterly and said, "It's not a little bit bad. This program is significantly behind in terms of database structure and vector data processing speed."

Fu Song smiled indifferently and said, "After all, ESRI has been done for almost twenty years, so we are not as normal as others. What other functions do we have?"

Sun Shaozong said: "This program is mainly to draw and manage vector data of the geographic information system. I also wrote a mini program for vectorizing raster data."

Fu Song hurriedly said, "Let me see it."

Sun Shaozong said while typing on the keyboard: "This program is mainly to convert the raster data scanned by paper maps into vector data with projection coordinates. It is very convenient to use it in conjunction with the program just now."

"Just, this is the main interface, and there are several functional modules, first of all, image correction. Many drawings are deformed due to the influence of humidity and temperature, and there will be deformation errors during scanning. The base map of the polyester film is better, and the paper map error is relatively large. In addition, the random errors generated by the scanner itself during scanning, such as vibration, operator proficiency, scanning software processing capabilities, etc. Before vectorization, you must first perform geometric correction on the deformed image. I use the mathematical model for correction. "

The more Fu Song heard it, the more familiar he felt. When he saw that Sun Shaozong had only struck a few lines of code, he corrected a simple deformed image. He finally thought of a famous software in later generations - b.

At first, B was just an interactive matrix calculator, and to put it bluntly, the processing of raster images is just matrix calculation!

Damn, it's really a good thing!

"Old Sun, it's amazing!" Fu Song wanted to hold Sun Shaozong and kiss him hard.

You are such a fucking talent! I love you so much!

"The transformation model is still a little problem..., let's change this later," Sun Shaozong shook his head and said to himself: "After correction, it can be vectorized. However, the vector data points tracked by vectorization are relatively large, and many points are unnecessary. For example, two points determine a straight line, but when vectorization is used, more than two points will be traced on a straight line. Therefore, the vector points and lines need to be diluted, which can reduce the amount of data and save storage space. However, the current dilution algorithm is relatively low in efficiency, especially the dilution of curves, I have to continue to change..."

At this time, Sun Ning came over and whispered: "Teacher Fu, there are five minutes left to have a meeting."

Fu Song didn’t even have time to hold a meeting now. In his opinion, the two programs written by Sun Shaozong were countless times more important than his own topic!

"You go and say to Professor Li and the others, wait a little longer, they are all their own people anyway."

When he heard what Zhang Ning conveyed, Professor Li and his friends had no objection, but instead surrounded the workstation with great enthusiasm and watched the excitement.

Of course, some people watch the fun, but experts can see the trick.

For example, Professor Qian, who works in humanities and geography like Fu Song, only looked at it for a while and said in surprise: "This program is good, is it done by our research team?"

Before Zhao Zhi could speak, Fu Song quickly coughed and said, "Of course not, there is no requirement for this result in the project book."

Fu Song was stupid and would classify these two software into the project results. He had just figured out that he would like to help Sun Shaozong continue to build these two software!

The meeting was delayed for half an hour before it officially started. After Fu Song gave a few simple words, the heads of each sub-project report on the progress of the project.

Although Fu Songren was sitting there, his mind was not on the subject at all. He had been thinking about how to convince Sun Shaozong to make these two softwares.

After lunch at the hotel where the meeting was held at noon, Fu Songxin opened a room and called Zhao Zhi and Sun Shaozong over.

As soon as Zhao Zhi entered the room, he went to the bed and crossed his legs and said, "Old Fu, you really know how to enjoy it. In order to take a nap, I even opened a room. Tsk, the life of rich people is really enviable! Lao Sun, don't be stunned, there is a bed, let's fight against the rich today!"

Sun Shaozong didn't listen to Zhao Zhi, so he found a chair and sat down, and asked, "Old Fu, what's the matter with us?"

Zhao Zhi got up from the bed and said, "Yes, it's so mysterious."

Fu Song slowly poured a cup of tea for them each and smiled and said, "Old Zhao, you just said that you envy the lives of rich people. How about I give you a chance?"
