Artificial intelligence empowers monitoring and supervision of Guangxi’s natural resources field

Fall monitoring radar, portable drone deception jamming gun, digital twin visualization platform... On the afternoon of July 13, the first China-ASEAN Artificial Intelligence Cooperation Forum was held in Nanning, Guangxi, and the forum’s special "Advanced Technology Exhibition" It showcases the technical achievements and products of enterprises, universities and research institutes related to the field of artificial intelligence.

"We mainly display the digital twin visualization platform, the 'Yikuaicha' remote sensing intelligent interpretation platform and intelligent remote sensing related products." said Wang Yucong, an engineer at the Guangxi Institute of Natural Resources and Remote Sensing.

In the past, the current status investigation of natural resource change monitoring mainly relied on operators to extract information through visual interpretation, which required a very large workload and required high time and labor costs. The emergence of remote sensing intelligent interpretation technology provides great convenience for remote sensing change monitoring. Intelligent interpretation technology can not only efficiently discover changes in ground objects in remote sensing images, but also automatically outline the scope of changes.

In order to serve the development of Guangxi’s natural resources business, the Guangxi Institute of Natural Resources and Remote Sensing used remote sensing intelligent interpretation technology to launch the “Yi Kuai Cha” remote sensing intelligent interpretation platform. This platform can automatically identify changes in various types of ground objects in remote sensing images, greatly improving the efficiency of remote sensing change monitoring. Currently, the platform has been used in the Guangxi Natural Resources Comprehensive Monitoring Project.

"It only takes 3 days from the extraction of remote sensing image change information to the push of map patches. This efficiency is more than 10 times higher than before." Wang Yucong introduced that changes in Guangxi are based on the intelligent change monitoring technology of remote sensing images. It only takes 8 hours to complete the extraction of construction change information across Guangxi, which greatly saves time and labor costs.

"In the past, we might have to invest more than ten people to extract the change patterns of a county for one or two weeks. Now, relying on the 'Yi Kuai Cha' remote sensing intelligent interpretation platform, three or four operators can do it for one or two days. It can be completed." Wang Yucong said.

By monitoring the geological environment, monitoring and early warning of geological disasters can be achieved. At the event site, the China-ASEAN cross-border geological disaster Beidou monitoring system exhibited by Guangxi Industrial Technology Research Institute attracted people's attention.

"Guangxi is an area prone to geological disasters, but many geological disasters are not sudden. They have a gradual process. We will monitor this process. If there is a certain trend, we will give early warning to let residents Evacuate, or give relevant departments an early warning so that everyone can take precautions in advance." said Li Youming, the relevant person in charge of the Guangxi Industrial Technology Research Institute.

It is understood that the China-ASEAN cross-border geological disaster Beidou monitoring system mainly uses Beidou/GNSS multi-mode precision positioning technology and remote sensing earth observation technology to monitor the deformation of target objects, realizing multi-dimensional and uneven deformation of disaster bodies. High-precision real-time dynamic measurement.

“In 2019, our monitoring system gave an early warning of a geological disaster in Nonggongtun, Xilin County, Baise City. The system detected a 30 cm displacement of the mountain 2 days in advance, and then issued an early warning signal, protecting more than 600 local people. The lives of villagers are safe," Li Youming said. Currently, the system has set up 21 monitoring areas in China and has been used as demonstrations in 7 overseas countries, including Cambodia, Laos, and Thailand, ensuring the safety of millions of people at home and abroad and the safety of nearly 10 billion in property.
