I heard that this is the star chased by the Martial Arts

A total of 6087 words, it takes about 19 minutes to read.

He said that ordinary life is eternal; he said that only by those who are prepared can "impossible" at that time "may be possible." He is a witness of history and the creator of history.

The development history of the remote sensing inspection and drawing discipline of Wuhan University is also the history of progress of national science and technology. The feelings of the country, reflecting the heart of the struggler, in the process of from scratch, it is the opportunity given by the times, and it is also the rebirth of countless ancestors after the frustration. Today, let the 85 -year -old scientist tell us about his scientific research.

Zhang Zuxun, an academician of the Chinese Academy of Engineering, an expert at the famous photography measurement and remote sensing of our country, a professor at the School of Remote Sensing Information Engineering of Wuhan University, and the winner of the "Outstanding Teaching Award" in 2021. He is an outstanding scientist who has achieved international first -class research results in the automation of aerospace imaging maps, completely breaking the monopoly of international software, leading my country's photography measurement industry to achieve leapfrog development; From teaching in 62 years, I have always passed the ideas of learning "not afraid of slowness, so I am afraid of standing" to students, do a good job of "teaching craftsmen", and be a good "Mr. Big". He has never fallen; he is a 61 -year -old party member of the party. In 2017, he donated 1 million to set up the "Teaching and Education Award". Continue remote sensing discipline.

*The following content is organized from Academician Zhang Zuxun's on -site report

In this special day of our party's 101 -year -old Chinese birthday, we will review and look forward to the development of photography measurement disciplines in Wuhan University, introduce their own growth experience, and make a work report for the party and the country, which is very meaningful. The topic I reported is "Born and Every Birth". Thinking again and again, only this question can express my mood and express the growth process of our subject research. This is the encounter given to us by the times and the development of our discipline.

Inheritance of the scientific spirit of the family, the country's feelings -Academician Zhang Zuxun's report meeting site

Not long ago, a video was spread in the alumni group of the remote sensing information engineering academy. In 1992, I delivered a speech at the CPGIS (International Conference on the International Chinese Geographical Information Science and Technology Conference). This is a prestigious international academic conference in the field of geographical information science, which has been held every year. The establishment conference was held at the Buffalo branch of the State University of New York. At that time, I was the vice president of Wuhan University of Surveying and Mapping Science and Technology. On behalf of the school, I congratulated the establishment of the conference on behalf of the school. Everyone was moved by watching the video, lamenting the rapid development of the discipline.

At that time, we transferred to Bafafaro to participate in the founding conference after participating in the International Photography Measurement and remote sensing conference in Washington. At the Washington Conference, the first digital photography measurement station was launched in the world. After a full 30 years, the full digital automatic diagram system of Wuhan University has continued to develop. From Virtuozo to DPGrid to cloud control, in the future, we will further strengthen the interdisciplinary cross and integration to better serve the needs of national economic and social and defense.

With the course of the development of discipline, I want to talk about three words: born at the time, born with me, and successor.

I have three unforgettable half a year in my life: one is half a year of studying in the Wild Factory in Switzerland, the other is half a year when I have been a soldier in the company, and the other is half a year in the countryside, so my experience is richer than ordinary teachers. At that time, graduated from graduate students and stayed in school, I was transferred to the military test (the former PLA Academy of Surveying and Mapping) to teach for more than 5 years. I never worked as a soldier when I was transferred. Be a soldier. After half a year of soldiers, there was no record in the file. Fortunately, I found a reward order given to me by the 486th regiment: "... With more than 50 pounds of weight, we took 6 Miles of enemy love for 6 miles and did not fall into the team ..." At that time, we used to be More than 1700 miles in Henan. Back to 1976, my classmate and I was also a teacher of Wu Tao Xuan Jiabin to study at the Wild Factory of Switzerland for half a year. This photo is the most advanced instrument at the instrument workshop with Xuan Jiabin and Swiss technicians in the instrument workshop.

In the mid -1970s, my country's terrain map testing was in a transition period from 1: 50,000 to 1: 10,000, and the measured and mapping instruments should be changed accordingly. In the past, we all used multi -fellows to draw a topographic map of 1: 50,000. At this time, the state imported one or two hundred sets of B8s instruments from Switzerland at this time. We need to send someone to learn how to use and repair. Originally, the production unit should be sent from the production unit. Considering that the teacher of the martial arts test does not need to bring a translation, the National Surveying and Mapping Administration decides that the school will send two people to study in Switzerland. I have liked to engage in instruments from staying at school. There is a instrument research room in the aviation test. I am very interested in photography measurement instruments. This is my study notes that year. Although I forgot everything now, I liked it at the time. Now I have the opportunity to study at the Swiss Instrument Factory. I am very happy in my arms.

Academician Zhang Zuxun's notes

We set off to Beijing on the afternoon of September 9, 1976. Chairman Mao died that day, and it was a day that would never be forgotten. When we got on the plane in Beijing, the two Chinese were foreigners. We took the DC-10 of the Swiss airline Douglas, from Beijing, Shanghai, Mumbai, Athens, to Zurich through 19 hours, and then drove to Berne, the capital of Switzerland.

At that time, the gap between my country and Switzerland was indeed very large. For the first time we entered the supermarket, the first time I saw the highway, and the first time I used a coin -call ... Just like Liu Ye in the Dream of Red Mansions entered the Grand View Garden, everything was fresh Essence Others see that we are "fresh". For example, after we were placed in Zurich in the early morning, the Secret of the Embassy's Business and the Second Secrets from Berne to Zurich Airport took us. Afterwards, they said that at a distance, just like the Chinese People's Liberation Army came, the two were uniformly dressing up: Zhongshan dress, snowflakes, snowflakes Well, wearing a hat, one person with a artificial leather bag with the word "Beijing". They took us to Berne and sent it to HEERBURGG, eastern Swiss town where the instrument factory was located. After checking in all procedures, they accompanied me to the supermarket to buy a short -wave radio in order to listen to Beijing's early news every night. Later, we knew from the radio to know the collapse of the "Gang of Four". After the ambassador's secretary returned to the place of residence with us, we thought, what kind of hospitality, thank you? Xuanjiabin was from Shanghai. He wanted to soak two cups of sugar. They did not drink it. After that, they suggested that in the future, do not use sugar water to entertain guests. You can buy more beer. We deeply realize the gap between "developed" and "not developed": sugar water and beer, this is the gap, too obvious.

Let ’s take a look at the TOSHIBA calculator I brought to you. Don't look at such a calculator. I particularly liked it at the time, and I felt very fresh. It was much more convenient to add and subtract, multiply, and remove it. After so many years, I turned out this calculator and could use the battery to use it. You see me knocking on 789, and then opened it. It immediately calculated it for you. This quality is really good. After I brought this calculator back to China, Teacher Yang Quanxing of the Computer Department often borrowed it, saying "this is the new generation of computers", so the small calculator represents the change of the times.

I am lucky and always meet a good time node. It didn't take long to come back from Switzerland to encounter two major events. One was held in the Third Plenary Session of the Eleventh Central Committee of the Party in December 1978, marking the new era of my country's entering reform and opening up; one was also at the end of 1978. My teacher Mr. Wang Zhizhuo proposed the "Research Plan for the Full Digital Automatic Importation System" at the second science and technology conference of the school, marking that the photography measurement entered the computer era, and no longer used the computer to calculate it with computers.

Mr. Wang Zhizhuo

This is the manuscript of Mr. Wang's plan. Look at the two pages of them. The first page is a full digital research plan. The other page is reference. The latest is 1976. Kreiling. In 1988, I encountered Kreiling at the exhibition of the ISPRS conference in Kyoto, Japan. Asked how he was all digitalized, he answered "Forget It", and he didn't do it at all. And how did Mr. Wang Zhizhuo do? Looking at the conditions at the time, the paper he used was worse than that I made teaching notes mentioned earlier. He studied all digitalization at the time. We often say that learning from scientists, especially from the old generation of scientists. Mr. Wang Zhizhuo's manuscript

The design plan needs to be demonstrated. It takes time and funds. But no one expected that the country ushered in a scientific spring. The project quickly passed the demonstration and then implemented it. It was implemented soon. I often joked with Mr. Wang Zhizhuo: First, only you can mention this solution. (At that time, the film in my country still used a traditional camera).

The project passed the demonstration and set up 1.2 million items. About 1981, we imported a full set of different sets from the United Kingdom. First of all, we must digitize the film, scan the scanner, and then enter the computer. This photo is the British NOVA3/12 computer and drum scanner. In a room where we temporarily closed the reconstruction, there is only one window, difficult conditions, and there are many difficulties in the project. At that time, the Nova machine had only 64K memory. I went to Hong Kong for three months. I learned to add assembly language from the Fortran4 language and use "page mapping" to expand the memory to 256K. The amount of data of the two photos requires 256m, and it is completely unable to deal with it. This is a big contradiction. In addition, the computer at that time had no display, and the image processing could only be dark. For example, the nuclear line arrangement, now students' internships can be done. It is very simple. At that time Half a year is very difficult. There are other difficulties, such as the concept of feature points have just been proposed, we are too late to learn; matching must be fast, and so on. These problems must be solved.

The drum scanner scandig3, computer Nova3/12 was introduced from the UK

Later, my doctoral students were completely different when they did it. In this picture, my first doctoral student in the late 1980s and early 1990s. My teacher Mr. Wang Zhizhuo came to visit our research. After reading it, he said, "Fun, two photos enter the three -dimensional three -dimensional three -dimensional, and there will be a three -dimensional three -dimensional. , Is it fun? "This was really novel at the time. Remember a staff member of the Natural Science Foundation of China said that other advanced technology, chemistry, physics, and see a lot, but the two photos are turned out of three -dimensional three -dimensional. I've seen it. This is the full digital project, which won the second prize of natural science.

Our products are made with 64K memory, which is not easy. Scientific research is a matter of time and money. Whether it can be successful or not know it beforehand, but one is sure, the opportunity is for those who are prepared. At that time, the memory was 1,000 times the speed of the memory from 64K to 64M at that time. The 1000 times was given to those who were prepared. Scientific research is to prepare in advance. You must not wait until mature. Everyone came to do it. If you are sorry, there is no place for you.

Not only our country, the world is like this. As mentioned earlier, Dr. Kreiling in Germany "Forget It" gave up, and Kern, Switzerland, did not succeed. Internationally put forward full digitalization in the world in 1992. In fact, Swiss KERN Corporation launched DSP1 full digital products at the Kyoto Conference in Japan in 1988. It is planned to be 500,000 Swiss francs, but one is not sold. At that time, the conditions were immature. In the end, the company was also acquired, but our products eventually went to the international market.

It is difficult to progress if there are not many factors in our growth process. Internationally, internationally in 1992, Professor Muraki Muraki Koji brought a team of industry delegation to find a product and told me to buy a set of our software with $ 10,000; set. I said yes, anyway, it is better than putting it in my drawer. Later, the village Jing Junzhi was the chairman of the International Photography Survey and Remote Sensing Society, and put it down. He wrote an article in 2002 to review the interview 10 years ago, the title was "China's IT industry landed in Japan", and it also mentioned the matter.

We have cooperated with Cubik since 1992. In 1994, we signed a 23 -page agreement with Australia. At the beginning, the Australian side faxed me with the agreement and signed it if we agreed. But they said that after the cooperation, the intellectual property rights were shared. I couldn't accept it. At that time, I was young. The newborn calf was not afraid of tigers. So they invited me to Australia, negotiated for two weeks, and finally signed a sales contract. I adhere to our intellectual property rights and sales rights in Greater China and Japan. In October that year, the Virtuozo workstation was officially released on the Australian Gold Coast, which was sold by Australia globally (except for designated countries and regions). This is the development process of our full digital automatic diagram system.

The second sentence I want to say is "born with me." Born to me, I must be useful. What I want to talk about is not myself, but my colleagues of our team.

This photo is the main member of our research group in the early 1980s, and the oldest is less than 50 years old. Among them, I want to introduce two people: one is Zhang Jianqing. He graduated from Nankai University in 1969. He studied mathematics. He is my main helper. He has made important contributions in image matching, image -related power spectrum, and photography measurement basic algorithms. Another Xu Xuan, he made a hardware and made a lot of contributions to the maintenance of the instrument. At that time, our laboratory used the World Bank loan to loan more than a million yuan from Switzerland to the positive projector or1 from Switzerland. The images could not come out. Swiss experts came to do it for us, but they were still old problems after they left. Xu Xuan found that there was a problem with the delay circuit of the instrument design. He added a resistor or a capacitor to extend the time delay a little bit, and the problem was completely solved. He later went to Leica to repair and maintain the measurement instrument. Everyone called him "Thousands of Guanyin", because he was clever, and any cutting -edge precision instrument would become docile. From him, we can see that "talent" is a kind of "enlightenment" and "inspiration", not learned in textbooks.

The third left in the first row is Zhang Jianqing, and the second left of the second row is Xu Xuan

If the university is a professor and a doctor, it is difficult to develop. There must be various talents. It is definitely a talent to write an article, and it is also a talent. It is not possible to rely on a talent. The team must have a variety of talents in order to do things.

The third sentence I want to say is "there are people in succession." I am 85 years old. It is not possible to do it, but it doesn't matter if you are old. Teachers' occupation is inheritance. In addition to scientific research, it is more important to cultivate students.

This is a photo of our team's 2022 New Year Tea. Compared with 40 years ago, we were old, but the team became bigger and the team was stronger. Professor Zhang Yongjun is already the dean of the School of Remote Sensing Information Engineering. At the college graduation ceremony this year, he also came to take a photo with me and said that he had graduated for 20 years to make up for this lesson. Zhang Yongjun's undergraduate was not measured by photography. During the doctoral stage, it was brought by Academician Liu Jingnan. Now he also has his own team. Professor Zheng Shunyi is a little legendary character. Many of the core technologies he founded by the China Guan Company are at the international leading level, and a number of new products are the first in the world. Remuneration has made a lot of dedication for the development of science and technology.

Zhang Zuxun team took a group photo of the New Year's New Year Tea in 2022

Academician Zhang Zuxun and Professor Zhang Yongjun took a group photo

The current team is indeed different from 40 years ago, but I think there is one thing that is the same, that is, the atmosphere is harmonious, supporting each other, and sharing results. For example, Professor Hu Xiangyun, who is artificial intelligence, often helps me compile software.

What else can we do after the full digitalization of photography? In fact, photography measurement is divided into two parts: internal and external industries. Before 2000, "full digitalization" mainly solved the problem of internal industry. After entering the 21st century The problem of control and painting, the essence of control is the problem of photography measurement big data. In the first 10 years of the 21st century, we developed the second generation of Vertiozo. The production efficiency was increased by more than 10 times and exported to the United States.

DPGRID Appraisal Meeting will be held in Guangzhou

My happiest is the successor, there are young people. Duan Yansong was born in 1975. In 2010, he came to Wuhan University before he officially got the title of an engineer at the company. Now his pockets are invited by the big American company ESRI. You can go to the embassy to apply for a work visa. He came to Wuhan University, and the school was very supportive. After cooperating with ESRI in the United States, Duan Yanong realized the matching method proposed by us in the late 1980s and early 1990s. ESRI said it was fast and good. He has now become a famous expert in the nation's famous large -faced camera, and also assumes a major special project of the 13th Five -Year Plan to the ground observation system.

Another young man is a associate researcher who was born in 1986. He is the chief teacher of the 19 million projects of the Aerospace System Department of the Strategic Support Force. This is also the third model of Wuhan University. The project review is excellent. In addition, based on the "cloud control", the domestic land observation satellite track refining software has been developed for the China Resources Satellite Application Center, which has significantly improved the accuracy of satellite positioning and made significant contributions to national defense.

The efficiency bottleneck brought by centralized storage

The development of disciplines, innovation is the core, unity is the foundation. At the 60th anniversary of the establishment of the surveying and mapping discipline in 2016, the "Wuhan University Daily" asked six academicians of the surveying and mapping discipline to talk about the culture of the discipline. Academician Li Daren talks about innovation, Academician Ningjin Sheng speaks unity, Academician Liu Jingnan speaks responsibilities, I talk about inheritance, Academician Gong Jianya talks about integration, Academician Li Jiancheng talks about it. Each academician summarizes two words. The discipline has a reference significance. In addition, the discipline must be integrated. If you only depend on photography to measure yourself, no matter how large the ability is useful, it must be supported by other disciplines, such as computers. During the process of completing the project, Wang Fuhong, a professor of the School of Surveying and Mapping, helped the satellite image setting track. The senior engineer of Maggie Lu Tao solved the key issues of the distribution and writing of the multi -source system. Strong points of university. In the end, what I want to emphasize is: do not forget the original intention, keep in mind the mission. thank you all!

Fan Jin Chao of the past, condensed for a century for a hundred years
