Vehicle trajectory prediction model based on highly correlated target driving
车辆移动轨迹预测是推动智能驾驶发展的重要技术.本文提出一种基于注意力的车辆轨迹预测模型.首先,针对不同车道对车辆移动的影响,提出基于注意力的高相关车道选择与候选预测轨迹终点生成方法,通过计算车道与地图元素的相关性分数,确定高相关车道,进而对高相关车道等距采样获得候选预测轨迹终点;其次,根据车辆移动受周围环境影响程度的不同,提出基于分支注意力的候选预测轨迹终点相关性分数计算方法,通过分别计算候选预测轨迹终点与历史轨迹、周边车辆、高相关车道以及车辆与车道交互信息的注意力值,确定候选预测轨迹终点相关性分数;最后,以候选预测轨迹终点相关性分数为基础进行目标选择,确定K个预测轨迹终点,并将其经过2层多层感知机得到完整预测轨迹.在Argoverse数据集上进行实验,结果表明,本文方法优于现有的TNT、DenseTNT等较先进的模型.
Vehicle movement trajectory prediction is an important technology to promote the development of intelligent driv-ing.A vehicle trajectory prediction model based on attention is proposed.Firstly,aiming at the influence of different lanes on vehicle movement,an attention-based method for selecting highly correlated lanes and generating candidate goals is pro-posed,the method determines the highly correlated lanes by calculating the correlation score between the lane and map ele-ments,and then the candidate prediction trajectory endpoints are obtained by equidistant sampling on the highly correlated lanes.Secondly,according to the different degrees to which vehicle movement is affected by the surrounding environment,a method for calculating the correlation scores of candidate prediction trajectory endpoints based on branch attention is pro-posed,the method determines the correlation scores of the candidate prediction trajectory endpoints by calculating the atten-tion values of the candidate prediction trajectory endpoints and historical track,surrounding vehicles,highly correlated lanes,and vehicle lane interaction information,respectively.Finally,based on the correlation scores of candidate predicted trajectory endpoints,target selection is carried out to determine K predicted trajectory endpoints,which are then processed through a two-layer multi-layer perceptron to obtain the complete prediction trajectory.Experiments are carried out on Argov-erse dataset,and the results show that the proposed model is superior to the existing advanced models such as TNT and DenseTNT.
