The invention discloses an urban airspace unmanned aerial vehicle conflict risk assessment method and system. The method comprises the following steps: determining flight data information of each unmanned aerial vehicle; determining one or more targets according to the flight data information; the target is an unmanned aerial vehicle pair with a mark; judging whether the first straight line intersects with the elliptical region or not to obtain a first judgment result of each target; if the first judgment result shows that the target does not exist, determining that the conflict strength and the conflict probability of the target are both 0; if the first judgment result shows that the target is the target, calculating the conflict strength and the conflict probability of the target; according to the conflict intensity and the conflict probability of each target, determining an urban airspace unmanned aerial vehicle conflict risk; according to the method, unmanned aerial vehicle conflict risk assessment taking the conflict probability and the conflict intensity as assessment indexes is realized, the practicability is good, and the requirements of urban airspace unmanned aerial vehicle operation safety assessment can be met.

    本发明公开了一种城市空域无人机冲突风险评估方法及系统,该方法包括:确定各架无人机的飞行数据信息;根据所述飞行数据信息,确定一个或者多个目标;所述目标为带有标记的无人机对;判断第一直线与椭圆区域是否相交,得到每个所述目标的第一判断结果;若所述第一判断结果表示否,则确定所述目标的冲突强度和冲突概率均为0;若所述第一判断结果表示是,则计算所述目标的冲突强度和冲突概率;根据每个所述目标的冲突强度和冲突概率,确定城市空域无人机冲突风险;本发明实现了以冲突概率和冲突强度为评估指标的无人机冲突风险评估,具有实用性好,能够满足城市空域无人机运行安全评估的需求和要求。
