The embodiment of the invention provides a collision early warning method and system based on cloud side-end cooperation. The method comprises the following steps: transmitting original data to an edge cloud; identifying data information of the original data, and performing structured classification and standardization processing on the original data according to the data information; according to the standardized data, in combination with a preset trajectory prediction model, calculating future trajectory information of the traffic participants; based on the trajectory information, performing collision check on the traffic participants, and calculating collision risk indexes of the collision participants; and the early warning urgency level of the traffic participant is judged in combination with the collision risk index and the collision index threshold value, early warning information is generated, and the generated early warning information is published to the central cloud when judgment is carried out. By adopting the method, the data calculation efficiency can be greatly improved, meanwhile, comprehensive collision detection is carried out on the traffic participants, the accuracy of a calculation result is improved, and efficient collision early warning between vehicles and between vehicles and vulnerable traffic participants is also realized.
本发明实施例提供一种基于云边端协同的碰撞预警方法及系统,所述方法包括:将原始数据传输至边缘云;识别原始数据的数据信息,根据数据信息对原始数据进行结构化分类和标准化处理;根据标准化数据,结合预设的轨迹预测模型,计算交通参与者的未来轨迹信息;基于轨迹信息,对交通参与者进行碰撞检查,计算碰撞参与者的碰撞风险指标;结合碰撞风险指标及碰撞指标阈值判断交通参与者的预警迫切等级,生成预警信息,并当判断生成预警信息发布至中心云。采用本方法能够大幅提升数据计算效率,同时也对交通参与者进行了全面的碰撞检测,提高了计算结果的准确性,也实现高效的车与车、车与弱势交通参与者之间碰撞预警。
