0199 This project is too simplistic

"Contour lines are projected vertically onto a horizontal plane, miniaturized on the drawing at scale, and complex mountain information is abstracted into a two-dimensional line plan, forming a contour map, and the numbers marked on the contour line are the elevation of the contour lines."

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

Professor Dong Boxue of the Faculty of Geographical Sciences of Beijing Normal University led a team to conduct a half-year research and went to Lushan for field investigation, and the scientific research team obtained a series of data from Lushan. However, because of the difficulty, the question was rejected by the international jury 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 Lushan, I think this question is too difficult, it is an impossible task, Wei, you should show the audience the relevant pictures." ”

Wei Qiankun was very unhappy, knowing that this was a ghost between the Japanese and the Americans, and he just wanted to use the contour map of Mount Fuji as the material for the problem, and then release water to his own team members.

As he spoke, a contour map of Mount Lu was released on the screen, which immediately caused an exclamation from the audience.

Of course, this is not an exaggeration.

Even on a large screen with an area of 100 square meters, it is impossible to tell where the mountain peaks are and where the valleys are from the map.

It's dense, and all the audience sees is countless contour lines, which is a headache.

At this time, Professor Dong Boxue, who has been in charge of the Lushan expedition, also stood up and spoke: "After several days of trekking, our team found that the challenge of this topic was far more difficult than previously expected. Because the scientific research team found in the field investigation that Lushan has a very strong deceptive nature, which is represented on the contour topographic map, the steep mountains and deep ravines are very similar and very difficult to distinguish, so this is a difficult task for humans to complete. ”

Wei Qiankun is angry here, the foreigners are holding back their stomachs, and they are worried that they can't find an excuse to change the topic, but they are good people, and they also make an assist.

If you don't try, how do you know if it's going to work?

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

The host Jiang Jingjian saw that the atmosphere on the field was a little embarrassing, so he hurriedly came out to play a round game, so that the show could continue.

There is no doubt that Mt. Fuji was used as the material for the question.

Jiang Jingjian: "On the contour map of the whole picture of Mount Fuji, flash a number of observation points from random perspectives, and generate a local real picture of the corresponding angle of each observation point, randomly select three real pictures on the spot, the contestants only observe the real map, draw the corresponding observation points and observation angles on the contour map, and the difference between the angle of the contestant's answer and the correct answer is within four degrees and the point offset is within 200 meters, then the answer is correct. The two players will compare the correct rate first, and the one with the same correct rate will win the shortest time. ”

Guest Momoko asked a question: "What kind of concept is the error of four degrees and two hundred meters?" Isn't the margin of error given a bit large? ”

Wei Qiankun came to life, and he hurriedly explained: "That's the case, our contestant uses the real scene to find the contour clip of the corresponding point, and the range of sight he sees in the real scene is not just a line or a surface, and the range of the real scene is very limited. ”

Wei Qiankun felt that it was very meaningful to ask this question, which could give the audience a more intuitive understanding of the difficulty of this challenge.

"Mt. Fuji is not bare, there must be shelter, which can cause miscalculation. Contestants need to extract the information obtained from the real picture for modeling, and then accurately calculate the position and bearing. ”

"The information is limited, and a lot of the information is overlapping, because the contour lines are closed curves, and there are so many similar points and line fragments. Therefore, the angle difference is within four degrees and the point deviation is within 200 meters, which is already very high and can be described as metamorphosis. Wei Qiankun smiled bitterly.

"I ...... I seem to understand something. The guest peach was confused, she didn't understand much about what Wei Qiankun said, but she already had a clear concept of error.

Wang Liang nodded again and again, he didn't watch the excitement, he understood the rules and everything.

There is only one two-dimensional section, and it is indeed not simple to use the real scene to find the corresponding point contour fragment.

This test is not geography at all, but requires strong 3D modeling ability, spatial rotation ability and mountain observation ability.

It's hard.

Wang Liang was still touching his chin and thinking, Jiang Jingjian noticed it, and asked, "Old chief, do you have any questions?" ”

Everyday interactions.

Wang Liang was slightly stunned, and then glanced at Kotaro Mitani, under the hypocritical appearance, Wang Liang realized the meaning of the villain's ambition.

Saying that nothing could make the conspiracy of the Japanese devils succeed, Wang Liang said: "I think it's too simple. ”

"Oh? Tell me more about it. "Jiang Jingjian is overjoyed, and there is good material for post-editing!

"Su Shi wrote in "The Title of the Western Forest Wall" that 'I don't know the true face of Lushan, only because I am in this mountain.' This is enough to see the changing appearance of our Lushan in China. Bai Juyi also commented on 'Kuanglu Qixiu Jiatianxia Mountain', which is to put Lushan in the first place among China's famous mountains. If you look at Mt. Fuji again, it's so far away......."

Wang Liang used methods such as giving examples, listing numbers, and making analogies to make arguments, in short, he degraded Mount Fuji to nothing.

"So I think the angle difference can be smaller, within two degrees, and the point offset is also calculated, within 100 meters, so that it can be 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 long remembered the relevant information of Mount Fuji.

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

That Kotaro Mitani must have prepared for this rule, and now Wang Liang proposed to change the error, which will inevitably have a big impact on him.

The preparations that had been made before were largely in vain.

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

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 in unison.

Davis, the international judge, didn't care, shrugged his shoulders, he just came to see the excitement.
