The invention discloses a multi-detection-mode traffic event fusion method based on a D-S evidence theory. The method comprises the steps that event data monitored by a radar, event data monitored by a video and event data judged by traffic operation characteristics are acquired; assigning the basic credibility of the event data of the three signal sources to generate a signal source basic credibility distribution table; performing fusion by using a D-S synthesis rule according to the signal source basic credibility distribution table to obtain a fused trust function; and using the D-S evidence theory to make a decision and output a complete event set. According to the method, the video traffic event data, the radar traffic event data and the traffic event data judged by traffic operation characteristic change are analyzed and researched, and a multi-monitoring-mode traffic event automatic monitoring fusion algorithm is provided, so that the efficiency and the accuracy of traffic event automatic monitoring are improved.

    本申请公开了一种基于D‑S证据理论的多检测方式交通事件融合方法,包括:获取雷达监测到的事件数据、视频监测到的事件数据和交通运行特征判定的事件数据;对上述三种信号源的事件数据的基本可信度进行赋值,生成信号源基本可信度分配表;根据上述信号源基本可信度分配表,使用D‑S合成规则进行融合,得到融合后的信任函数;使用D‑S证据理论进行决策输出完整的事件集合。本申请通过对视频交通事件数据、雷达交通事件数据和交通运行特征变化判断的交通事件数据进行的分析研究,提出多监测方式交通事件自动监测融合算法,以提高交通事件自动监测的效率与准确性。
