基于低空数字孪生的风险量化评估与安全航线规划应用研究OA

To address the current problems of inadequate low-altitude airspace management,imprecise risk assessment,and the lack of safety evaluation in route planning,this paper proposes a technical framework for risk quantification assessment and safe flight route planning based on low-altitude digital twins.Using the BeiDou grid as a reference,the framework manages low-altitude airspace and environmental elements,establishing an integrated ground-air risk quantification model.Based on the results of risk assessment and an improved A* algorithm,low-altitude flight routes are generated.Field experiments are conducted in a typical urban area in Henan Province,validating the effectiveness of the proposed technology.This approach provides support for the efficient utilization of low-altitude airspace and route planning.
