The invention discloses a vehicle frequent lane change identification method and device based on sparse satellite positioning data. The method comprises the steps: responding to an equipment identifier and satellite positioning data of a vehicle-mounted satellite positioning device, and integrating the equipment identifier and the satellite positioning data to form formatted data; based on the data of three adjacent moments in the acquired formatted data, judging whether a vehicle carrying a positioning device with an equipment identifier of k at the three adjacent moments changes a lane or not; calculating a data mean value mu and a standard deviation sigma of the data set; and based on the data mean value mu and the standard deviation sigma, judging whether the vehicle carrying the positioning device with the equipment identifier of k has a frequent lane changing condition or not. According to the invention, through the positioning data, the nk(i-1, i, i+1) is calculated, and the change condition and the frequency degree of the direction of the vehicle are indirectly judged, so that the lane change condition and the frequency degree are judged by judging whether the direction of the vehicle deviates or not so as to improve the accuracy of identifying the lane change and the frequent lane change of the vehicle.
本发明公开一种基于稀疏卫星定位数据的车辆频繁变道识别方法及装置,方法包括:响应于获取车载卫星定位装置的设备标识和卫星定位数据,对所述设备标识和所述卫星定位数据进行整合形成格式化数据;基于获取所述格式化数据中相邻的三个时刻的数据,判断在经过相邻三个时刻载有设备标识为k的定位装置的车辆是否变道;计算以为数据集的数据均值μ和标准差σ;基于所述数据均值μ和所述标准差σ,判断载有设备标识为k的定位装置的车辆是否有频繁变道情况。通过定位数据进行计算nk(i‑1,i,i+1)和来间接判断车辆方向的变化情况及频繁程度,实现通过判断车辆是否有方向偏离来判断变道情况及频繁程度,从而提高了对车辆变道及频繁变道识别的准确度。
