Summary
The academic presentation will focus on the latest achievements of Professor Zhang Qin's research team in the field of BeiDou/GNSS landslide monitoring and warning technology based on Unmanned Aerial Vehicle (UAV) deployment. In response to the challenges posed by high-locality, long-distance and emergency landslide scenarios, where traditional non-remote monitoring equipment deployment is difficult, data transmission is hindered, personnel risks are high, and unmanned monitoring deployment technology remains unexplored, the research team have developed a BeiDou multi-sensor (integrated accelerometer, inclinometer, etc.) monitoring equipment that uses UAV to drop quickly and accurately over a long distance by Comprehensive utilization of BeiDou, unmanned aerial vehicle (UAV), big dipper ad-hoc network communications, intelligent control, and advanced remote sensing technologies. In this way, the observation data is transmitted to a cloud-based processing platform through the space-air-ground integrated real-time transmission network. The enhanced positioning algorithm of the BeiDou cloud platform is used to obtain high-precision deformation sequences, and finally, intelligent monitoring and accurate warning of landslide hazards are realized.
Keynote Speaker
Prof. Zhang Qin currently holds the position of a professor (second-level) in the Department of Surveying Science and Engineering at the School of Geological Engineering and Geomatics, Chang'an University, while also fulfilling roles as a doctoral supervisor and a Chang'an Distinguished Professor. She is the director of Institute of Spatial Positioning and Disaster Monitoring of Chang'an University, winning the title of advanced individual teacher ethics in Shaanxi Province, serving as the director of the China Surveying and Mapping Association, the executive director of the China Satellite Navigation and Positioning Association, and the deputy director of the Urban Spatial Information Committee of the China Geographic Information Association.
