The invention discloses an early warning method and system for a non-vehicle target, and relates to the field of intelligent safe driving. The method comprises the steps of obtaining image informationof a forward road of a vehicle; acquiring pedestrian crossing area information from the image information, and acquiring non-vehicle target distribution density information in a preset area includingthe pedestrian crossing area; identifying each non-vehicle target in the preset area according to a preset non-vehicle target re-identification algorithm, and determining a driving direction and a driving speed of each non-vehicle target; and outputting driving early warning information to the vehicle according to the non-vehicle target distribution density information and the driving direction and the driving speed of each non-vehicle target. According to the invention, the accuracy of the early warning information can be improved by comprehensively considering the driving direction of non-vehicle targets such as pedestrians and non-motor vehicles, the attention of drivers of the non-vehicle targets such as the pedestrians and the non-motor vehicles, the pedestrian density, the non-motorvehicle flow and other multi-dimensional fusion information.
本发明公开一种针对非车辆目标的预警方法及系统，涉及智能安全驾驶领域，所述方法包括：获取车辆前行道路的图像信息；从所述图像信息中获取人行横道区域信息并获取包含有所述人行横道区域的预置区域内的非车辆目标分布密度信息；根据预置非车辆目标重识别算法对所述预置区域内的每一个非车辆目标进行标识，并确定每一个非车辆目标的行驶方向及行驶速度；根据非车辆目标分布密度信息和所述每一个非车辆目标的行驶方向及行驶速度向所述车辆输出行驶预警信息。本发明通过综合考虑行人及非机动车等非车辆目标的行驶方向、行人及非机动车等非车辆目标驾驶人的注意力、行人密度及非机动车车流量等多维度融合信息，可以提升预警信息的准确性。
