The invention discloses an abnormal vehicle determination method and device, a vehicle and a storage medium. The method comprises the following steps: acquiring a first spatial-temporal trajectory feature of a to-be-detected vehicle in a target road section; determining a first intra-group relation coefficient by using a template trajectory feature and the first spatio-temporal trajectory feature, the template trajectory feature being determined according to a second spatio-temporal trajectory feature of a sample vehicle in the target road section, and the first intra-group relation coefficient being determined according to the second spatio-temporal trajectory feature of the sample vehicle in the target road section; the first intra-group relation coefficient is used for representing the relevancy between the template trajectory feature and the first spatio-temporal trajectory feature; and determining whether the to-be-detected vehicle is an abnormal vehicle according to the first intra-group relation coefficient. According to the technical scheme provided by the embodiment of the invention, the space-time trajectory characteristics of the vehicle in the target road section are comprehensively considered, and compared with a traditional mode of judging the abnormal vehicle by depending on the speed of the vehicle, the consideration is more comprehensive, the detection accuracy is higher, and more manpower is saved.
本发明公开了一种异常车辆的确定方法、装置、车辆及存储介质。该方法包括:获取目标路段中待测车辆的第一时空轨迹特征;利用模板轨迹特征和所述第一时空轨迹特征,确定第一组内关系系数,其中,所述模板轨迹特征根据所述目标路段中的样本车辆的第二时空轨迹特征确定,所述第一组内关系系数用于表征所述模板轨迹特征和所述第一时空轨迹特征的相关度;根据所述第一组内关系系数确定所述待测车辆是否为异常车辆。本发明实施例的技术方案,综合考虑了车辆在目标路段中的时空轨迹特征,与依赖车辆的速度来判断异常车辆的传统方式相比,考虑更全面且检测准确度更高,更节省了人力。
