CCTV News: On September 27, the first national cultural protection equipment application exhibition sponsored by the State Administration of Cultural Heritage opened in Chongqing. Science and technology are deeply integrated with archaeology and cultural preservation, and technology and equipment are changing with each passing day. A remote sensing satellite that crosses mountains and seas under the firmament. At the National Cultural Protection Equipment Application Exhibition, the "Sky-Ground" collaborative perception system was collectively unveiled, making monitoring and protection handy.
The star of "Tian" is equipped with "CubeSat", which is the first small satellite serving the field of cultural relics on the mainland, which can not only collect visible light spectrum, but also collect cross-electromagnetic spectrum information covering infrared to ultraviolet light.
The protagonist of "air" is the drone, the cruising speed can reach tens of kilometers per hour, and low-altitude close-up monitoring of the site can obtain clearer and more detailed three-dimensional status, characteristics and other information.
The "sky-ground" collaborative perception system not only covers a wider area, but also sees more finely. Through real-time feedback, emerging problems can be dealt with in a timely manner, providing an efficient, flexible and rapid solution for the protection of large unattended sites in the wilderness.
Dong Wenqiang, Dean of the Institute of Cultural Heritage of Northwestern Polytechnical University: "Ground" mainly adopts high-definition visual platforms, including field site monitoring and perception instruments such as ground weather stations, to monitor and perceive the natural environment such as hydrometeorology and tourist flow of sites and remains around the clock.
A set of "sky-ground" collaborative perception system composed of satellites, drones and ground monitoring and perception instruments vividly shows how to integrate data collection, transmission, presentation, analysis and other functions, so as to provide all-round and multi-scale intelligent monitoring for large-scale field archaeological sites.
