The invention discloses a vehicle lane changing judgment method, device and system and a storage medium. The method, device and system are used for accurately recognizing vehicle lane changing behaviors. The method comprises the following steps: when a lane changing detection event is triggered, calculating each vertex position of a vehicle at the current moment; determining a first vector by taking a lane starting point corresponding to a lane line passed by the vehicle during lane changing as a starting point and taking a vertex position of the vehicle at the current moment as a terminal point; performing cross-riding on the first vector and a second vector corresponding to a lane line through which the vehicle passes during lane changing; and judging whether the vehicle changes the lane according to the cross-riding calculation result. By adopting the scheme, the relative position relationship between the vertex position of the vehicle and the lane line can be calculated and determined according to each vertex position of the vehicle, so that the lane changing behavior of the vehicle is accurately identified, and the false alarm probability of lane changing of the vehicle is reduced.

    本申请公开了一种车辆变道判断的方法、装置、系统及存储介质,用以准确识别车辆变道行为。所述方法包括:当触发变道检测事件时,计算车辆当前时刻的各个顶点位置;将车辆变道时所经过的车道线对应的车道起点作为起点,将车辆当前时刻的顶点位置作为终点确定第一向量;将所述第一向量与车辆变道时所经过的车道线对应的第二向量进行叉乘;根据叉乘计算结果判断车辆是否变道。采用本方案可以根据车辆各个顶点位置,计算确定车辆顶点位置与车道线的相对位置关系,进而准确识别车辆变道行为,降低车辆变道的误报概率。
