"One who fails to reach the Great Wall is not a hero." The Great Wall is known as one of China's symbols. But this majestic ancient building that has stood in China for nearly two thousand years has long lost its original majesty due to the erosion of the years.

The Great Wall, the "Great Wall" in our mouth, is the greatest and most majestic military defense project in ancient China. The oldest Great Wall in history dates back to the Western Zhou Dynasty. During the Spring and Autumn Period, the Great Wall built the first climax, and the various vassal states built the Great Wall fortifications on their respective borders. However, the Great Wall during this period was relatively short and relatively low. After Qin and the Six Kingdoms joined together with China, they repaired the Great Wall links of the various vassal states and they were known as the Great Wall. The Ming Dynasty was the last era to overhaul the Great Wall. The Great Wall that we can see this year is mostly the buildings of this period.

The Great Wall resources are mainly distributed in 15 provinces, municipalities and autonomous regions such as Beijing, Tianjin, Hebei, Shaanxi, Shanxi, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Ningxia and Xinjiang. According to the National Great Wall Resources Survey conducted by the Chinese Cultural Relics and Surveying and Mapping Department, the total length of the Ming Great Wall is 8851.8 kilometers. According to...Continue Reading

Speaking of surveying and mapping, I think everyone will not be unfamiliar.
From engineering construction to land management, people are often inseparable from the help and assistance of surveying and mapping. In the past, traditional surveying and mapping relied mainly on manpower, not only to face a broad and complex geographical environment, but also to worry about the danger of disasters at any time. The mapping can be described as being intimidating, inefficient, and safe. However, with the development of the times and the emergence and application of various intelligent technologies, today's surveying and mapping has changed a lot.

UAV became the "new favorite" of surveying and mapping

One of the most obvious changes is the application of drones.

In recent years, with the rapid development of technologies such as flight control, navigation and communication, drones have gradually become the "new vents" for people's attention and application, from agricultural plant protection to power inspection, from film and television shooting to fire rescue, from emergency Communication to traffic inspections, we can see the drone's healthy posture.

With the gradual opening of the consumer market, its industrial-grade applications have continued to land, and the field of surveying and mapping has become a new airspace for its soaring. The UAV, which incorporates remote sensing technology, has been widely praised by people in the surveying and...Continue Reading

Standing in the field, Lu Jiyu raised the Notuzi X85 drone to a height of 100 meters by manipulating the remote control in his hand, taking a picture of the whole watermelon field, and then using the big data formula to calculate the number of watermelons, quickly completing the past and causing headaches for farmers. The "number of watermelons" puzzle.

Lu Ji’s Hualien is an important watermelon producing area in Taiwan, with an annual output of more than 30,000 tons, ranking first in Taiwan. Lu Jiyu’s Shoufeng Township in Hualien County, the watermelon produced, feels the market with a full, sweet mouth. Because of the large number and difficulty in calculating, the farmers usually only have to "guess" the quantity and then negotiate the price with the middle, which is often suppressed.
Recalling the experience of watermelons in the past, Lu Jiyan said frankly, how to calculate is not good. He cooperated with friends who love to play drones and developed the use of MMC drone high-altitude image inventory technology to finally solve this problem. It was later proved that the amount estimated by the aerial shot was quite accurate. With reference data, farmers have the bargaining power of bargaining with middlemen, and they can choose favorable timings for shipments based on market conditions to obtain greater returns. Later, this technology was also used to monitor crop growth and assess a wide range of areas such as damage.

Lu Jiu, 39, originally...Continue Reading

A large part of the debugging work of the drone is the debugging of flight control parameters. The generalized flight control parameters include guidance, navigation, control law and adjustable parameters in various control strategies. The general flight control has hundreds of parameters that require human debugging, and some even hundreds of thousands. As the basis of drone control, attitude control is the first to be the first to debug the UAV flight test. Of course, the navigation parameters and the vibration analysis of our previous PX4 combat are definitely before the debugging posture. Better state.

The attitude parameter debugging method we are going to talk about today is for the most widely used cascade PID controller. In the attitude control, the controller based on the time-scale separation hypothesis is generally divided into inner and outer ring structures, and the inner ring controls the attitude angle. Rate, outer ring controls the attitude angle. The separation of time scales means that the inner loop responds much faster than the outer loop, so the inner loop response can follow the expectations given by the outer loop in a short period of time. The P (outer ring)-PID (inner ring) type structure used in PX4 is designed in this way. The design of the control law for attitude control will be discussed later and will be described separately for the Euler angle and the quaternion. Discussion. Today we will talk about how the parameters of the P-PID inner and

Wildlife is an important part of natural ecosystems, protecting them from global ecological health and safety. Wildlife conservation work should first investigate the population resources, understand the exact distribution of species, population size, habitat changes, etc., and provide a scientific basis for further assessment of species quality of life, determination of protection levels and development of appropriate protection strategies. However, this important basic work is extremely difficult to implement under the conditions of mountain forests.

Recently, the Qinling Golden Monkey Research Team of the College of Life Sciences of Northwest University applied the drone with thermal camera to the wild Sichuan golden monkey distribution and population size survey in the Qinling area. In the survey area, the research team collected thermal imaging videos of the wild populations of the three groups of Rhinopithecus roxellana, and obtained accurate distribution locations and population sizes of these populations.

What is the traditional wildlife survey method?

He Gang, an animal protection expert from the Qinling Rare and Endangered Animal Conservation Key Laboratory of Shaanxi Province, said that traditional wildlife surveys are usually conducted by experienced investigators entering the survey area, conducting field surveys along the design line, and passing through manual observation records. The animal entities and traces found to determine the species...Continue Reading

Utilize drones to carry out investigations on hidden dangers of geological disasters to ensure the safety of people's lives and property during the flood season. With the continuous expansion of the application field, more and more drones are participating in our lives, especially the advancement of industrial drone technology, making investigations safer and more convenient.

Due to the complicated geological conditions in the southwestern part of China, the geological disasters such as various types of landslides and collapses are prone to occur during the flood season, and the geological disaster prevention and control situation are very serious. In mountainous areas, geological disasters are more serious, and many regional roads are also slightly deformed. It is suspected that there are hidden dangers in disasters. In order to further confirm the degree of risk, the Geological Team staff conducted a high-altitude aerial survey of the entire area through the on-the-spot investigation and collected a high-definition image map reflecting the real-time status of the entire hidden danger point for preliminary analysis, combined with the comprehensive judgment of the survey information. The overall decline in the region is unlikely, and the risk of disasters is low.

The drone survey is the Griffion M8 of MMC UAV, the leading industrial drone manufacturer in China. The Griflion M8 is a vertical take-off and landing (VTOL) fixed-wing UAV with the V-shape tail which is made
