The invention provides a trajectory anomaly detection method and device, electronic equipment and a readable storage medium. The method comprises the following steps: acquiring historical driving trajectory information and real-time driving trajectory information of a target object; performing density clustering on the historical driving track information, and obtaining a daytime resident place and a night resident place of the target object based on a density clustering result; based on the first historical staying duration of the target object in the daytime resident place and the second historical staying duration of the target object in the nighttime resident place, obtaining a daytime and nighttime judgment proportion; based on the real-time driving track information, obtaining a first real-time staying time length of the target object in a daytime resident place and a second real-time staying time length of the target object in a night resident place, and obtaining a daytime and nighttime real-time proportion; and detecting whether the real-time driving track of the target object is abnormal or not based on a comparison result of the daytime running and nighttime running judgment proportion and the daytime running and nighttime running real-time proportion. According to the method, data redundancy can be effectively removed, the operation time consumption is reduced, and the abnormality judgment accuracy is improved.

    本发明提供一种轨迹异常检测方法和装置、电子设备及可读存储介质,其中所述方法包括:获取目标对象的历史行驶轨迹信息及实时行驶轨迹信息;对历史行驶轨迹信息进行密度聚类,基于所述密度聚类的结果获得目标对象的日间常驻地和夜间常驻地;基于目标对象分别在日间常驻地的第一历史停留时长和夜间常驻地的第二历史停留时长,得到昼伏夜出判断比例;基于实时行驶轨迹信息,获取并基于目标对象分别在日间常驻地的第一实时停留时长和夜间常驻地的第二实时停留时长,得到昼伏夜出实时比例;基于昼伏夜出判断比例、昼伏夜出实时比例的比较结果,检测出目标对象的实时行驶轨迹是否异常。本发明可有效去除数据冗余,降低运算耗时,提高异常判断的准确性。
