The invention provides a trajectory prediction method, a trajectory prediction device and Internet of Vehicles equipment. The method is applied to a main vehicle and comprises the following steps: acquiring n historical track point sets under a vehicle body coordinate system; wherein one historical track point set is obtained by a historical track of a remote vehicle; screening the n historical track point sets to obtain m target historical track point sets; wherein 1 < = m < = n, and m and n are positive integers; mapping each historical track point in the m target historical track point sets to the driving direction of the main vehicle to obtain a mapping coordinate point set; and forming a predicted trajectory of the main vehicle according to the mapping coordinate point set. According to the scheme of the invention, the problem of prediction errors caused by single or inaccurate sample data can be avoided, and the accuracy of trajectory prediction is ensured.
本发明提供了一种轨迹预测方法、装置及车联网设备。方法应用于主车,所述方法包括:获取车身坐标系下的n个历史轨迹点集;其中,一个所述历史轨迹点集由一个远车的历史轨迹获得;对n个所述历史轨迹点集进行筛选,得到m个目标历史轨迹点集;其中,1≤m≤n,且m和n为正整数;将m个所述目标历史轨迹点集中的每个历史轨迹点映射至所述主车的行驶方向上,得到映射坐标点集;根据所述映射坐标点集,形成所述主车的预测轨迹。本发明的方案能够避免由于样本数据单一或不够精确时带来的预测误差的问题,保证了轨迹预测的精确度。
