Chapter 199 This project is too simple

0199 This project is too simple

"Contour lines are vertically projected onto a horizontal plane, scaled down on the drawing, and the complex mountain information is abstracted into a two-dimensional line plan to form a contour map. The number marked on the contour line is the contour line. the altitude of the line."

After the popular science knowledge was finished, Wei Qiankun started to get down to the topic: "Today's [Contour Identifying Mountains] project has two sets of questions, one is the contour map of Mount Lu in China, and the other is the contour map of Mount Fuji in Japan. .”

"Professor Dong Boxue from the Department of Geographical Sciences of Capital Normal University led a half-year research team and went to Lushan Mountain for field investigation. The scientific research team obtained a series of data on Lushan Mountain. But because it is too difficult, this question It was consistently rejected by the international reviewer Professor Davis and Professor Yoshida Yuta of the Faculty of Science of the University of Tokyo." Wei Qiankun said.

Davis shrugged his shoulders: "Yes, after seeing the panorama of Mount Lu, I think this question is really too difficult and an impossible task. Wei, you should show the audience the relevant pictures."

Wei Qiankun was very upset, knowing that the Japanese and Americans were playing tricks together, and he just wanted to use the contour map of Mount Fuji as the material for the question, and then give water to his team members.

As he said that, the contour map of Lushan Mountain was released on the screen, which immediately caused a burst of exclamation from the audience.

Of course, this is not an exaggeration.

Even if it is placed on a large screen with an area of ​​[-] square meters, it is impossible to tell from the picture where are the peaks and where are the valleys.

It is densely packed, and what the audience sees are only countless contour lines, which is a headache.

At this time, Professor Dong Boxue, who has been in charge of the Lushan investigation, also stood up to speak: "After several days of trekking, our team found that the challenge of this topic far exceeded our previous expectations. Because the scientific research team conducted field investigations in the field It was found in the study that Lushan Mountain is very confusing, and it is shown on the contour topographic map that the steep mountains and deep valleys are very similar and very difficult to distinguish, so this is a difficult task for human beings to complete.”

Wei Qiankun was so angry that the foreigner was full of bad water, and was worried that he couldn't find an excuse to change the topic, but he was a good person, and he even played an assist.

If you don't try it, how will you know if it will work.

At this time, Wang Liang suddenly realized that it was so.

The host Jiang Jingjian saw that the atmosphere on the stage was a bit awkward, so he hurried out to smooth things over so that the show could continue.

There is no doubt that Mount Fuji was used as the material for the topic.

Jiang Jingjian: "On the overall contour map of Mt. Fuji, a number of observation points from random perspectives are flashed, and a partial real-scene picture corresponding to each observation point is generated. Three real-scene pictures are randomly selected on the spot. The contestants only observe the real-scene picture. The corresponding observation points and viewing angles are drawn on the high-line panorama map. If the angle difference between the contestant’s answer and the correct answer is within four degrees and the point offset is within 200 meters, the answer is correct. The two contestants first compare the correct rate, and the correct rate is the same Whoever takes the shortest time wins."

The guest Taozi raised a question: "What kind of concept is the error of four degrees and 200 meters? Is the error range given a bit too big?"

Wei Qiankun came to life, and he quickly explained: "It's like this, our contestants use the real scene to find the contour line segments of the corresponding points, and the sight range of the real scene he sees is not just a line. Or as simple as a surface, the scope of real scene shooting is very limited.”

Wei Qiankun felt that it was very meaningful to ask this question, which would allow the audience to understand the difficulty of this challenge more intuitively.

"Mount Fuji is not bare, and there must be occluders, which will cause misjudgment. The contestants need to extract the information obtained from the real-view image for modeling, and then refine it to calculate the position and orientation."

"Information is limited, and a lot of information is overlapping, because contour lines are closed curves, and there are many similar points and line segments. Therefore, the angle difference is within four degrees and the point offset is within 200 meters. , this request is already very high, it can be described as abnormal." Wei Qiankun smiled wryly.

"I, I seem to understand a little bit." The guest Taozi was at a loss. She didn't understand much of what Wei Qiankun said, but she already had a clear idea of ​​the error.

Wang Liang nodded again and again, he was not just watching the fun, he understood all the rules.

There is only a two-dimensional section, and it is really not easy to use the real scene to find the contour line segment of the corresponding point.

This test is not about geography at all. Contestants need to have super three-dimensional modeling ability, spatial rotation ability and mountain perspective observation ability.

Difficult.

Wang Liang was still rubbing his chin to think. Jiang Jingjian noticed it and asked, "Old chief, do you have any questions?"

daily interaction.

Wang Liang was slightly taken aback, then glanced at Kotaro Mitani, under the hypocritical appearance Wang Liang realized the meaning of a villain's success.

No matter what you say, you can't let the Japanese devil's plot succeed, Wang Liang said: "I think this project is too simple."

"Oh? Tell me more about it." Jiang Jingjian was overjoyed, and there are good materials for post-editing!
"Su Shi wrote in "Tixi Linbi" that 'I don't know the true face of Lushan Mountain, but because I am in this mountain.' This is enough to see the changing appearance of Lushan Mountain in China. Bai Juyi also commented on 'Kuanglu Qixiujia "Mountains of the world", this is to put Mount Lu at the top of the famous mountains in China. Look at Mount Fuji, it is far away."

Wang Liang used examples, numbers, and analogies to demonstrate. In short, he demoted Mount Fuji to nothing.

"So I think that the angle difference can be as small as possible. If it is within two degrees, the point offset will be counted. If it is within 100 meters, then it is considered difficult." Wang Liang said.

Wang Liang's purpose is very clear. The Japanese have repeatedly clamored to use Mount Fuji as the material for the question. Combined with the conversation he heard in the corridor, it is obvious that the Japanese players have memorized the relevant materials of Mount Fuji.

Four degrees, 200 meters, players have long known this error rule.

That Kotaro Mitani must have prepared according to this rule. Now that Wang Liang proposes to change the error, it will definitely have a big impact on him.

Previous preparations have largely been for naught.

Jiang Jingjian was just the host, he couldn't make up his mind, so he couldn't help but look at the chief scientific judge Wei Qiankun.

Wang Liang's words undoubtedly opened Wei Qiankun's mind, "Our team of scientists needs to discuss it."

Sure enough, Kotaro Mitani and Yuta Yoshida frowned at the same time.

The international judge Davis didn't care, he shrugged, he just came to watch the excitement.
