摘要/Abstract

摘要： 为保证无人机(UAV)在城市区域安全运行,建立基于城区行人安全的UAV运行风险评估模型。首先,分析UAV在城区运行时对行人造成的威胁,进行风险建模;其次,引入风险衡量标准,建立风险成本计算指标;然后,生成UAV城区运行风险地图;最后,以基于风险规避的UAV路径规划为应用场景,求解UAV在城区中的飞行任务路径。结果表明:不同区域的风险成本区别明显,风险程度与人群密度、环境遮蔽效果有关;与传统的距离最短路径规划方法相比,考虑运行风险的路径规划方法能够使UAV的飞行路径避开危险程度较高的区域,提高UAV在城区运行的安全性。

Abstract: In order to ensure safe operation of UAVs in urban areas, an UAV operation risk assessment model considering safety of ground pedestrians was put forward. Firstly, safety threats it caused to ground people were analyzed and risk modelling was conducted. Secondly, assessment standards were introduced and risk cost calculation indicators were defined before an UAV operation risk map was generated. Finally, solution for operation path was resolved with risk-avoiding UAV path planning as an application scenario. The results show that risk costs vary significantly in different areas and risk degree is relevant to population density and sheltering effect of the environment. Compared with shortest-distance-based path planning method, risk-cost-based method enables UAVs to avoid highly dangerous areas, thus improving safety of its operation in urban areas.

Key words: safety of ground people in urban areas, unmanned aerial vehicle (UAV), risk assessment, risk cost map, path planning
