The invention relates to a multi-view fusion intelligent crossroad vehicle trajectory prediction and accident early warning method, which is used for extracting crossroad feature nodes based on multi-view fusion and realizing the construction of a crossroad panoramic three-dimensional space model by utilizing three-dimensional reconstruction voxel modeling. A fusion model is established, vehicles and pedestrians passing through a crossroad are detected in real time, tracking prediction is performed according to a motion track, and meanwhile, early warning can be performed on an accident through information interaction between roadside equipment and a vehicle-mounted unit. And the space positions of the vehicles and the pedestrians are matched into the panoramic three-dimensional space model of the crossroad, so that the problem of single-view-angle shielding is solved.

    本发明为多视角融合的智慧十字路口车辆轨迹预测及事故预警方法,基于多视角融合对十字路口特征节点提取,并利用三维重建的体素建模实现了十字路口全景三维空间模型的构建。建立融合模型,对通过十字路口的车辆、行人进行实时检测以及根据运动的轨迹进行追踪预测,同时通过路侧设备与车载单元进行信息交互可以对发生的事故进行预警,并根据车辆和行人的空间位置匹配到十字路口的全景三维空间模型中,解决了单视角遮挡的问题。
