The invention discloses a collision early warning method and device, and the method comprises the steps: obtaining detection data through a roadside smart base station disposed at a preset position, and enabling the detection data to comprise the motion information of a first target and a second target in a sensing range of the roadside smart base station; motion areas are obtained according to the detection data, the motion areas comprise a first motion area and a second motion area, the first motion area refers to the motion area of the first target predicted at the future moment, and the second motion area refers to the motion area of the second target predicted at the future moment; obtaining a collision expectation value according to the first motion area and the second motion area, wherein the collision expectation value is used for indicating the probability of collision between the first target and the second target and the collision danger degree; and outputting early warning prompt information according to the collision expected value, wherein the early warning prompt information comprises emergency early warning information and weak collision early warning information. According to the technical scheme, the accuracy of collision early warning can be improved, and the collision risk of the target is effectively reduced.

    本申请公开一种碰撞预警方法与碰撞预警装置,该碰撞预警方法包括:利用布设在预设位置的路侧智慧基站获取检测数据,检测数据包括路侧智慧基站感知范围内的第一目标与第二目标的运动信息;根据检测数据得到运动区域,运动区域包括第一运动区域与第二运动区域,第一运动区域是指预测在未来时刻第一目标的运动区域,第二运动区域是指预测的在未来时刻第二目标的运动区域;根据第一运动区域与第二运动区域得到碰撞期望值,碰撞期望值用于指示第一目标与第二目标发生碰撞的概率和碰撞危险程度;根据碰撞期望值输出预警提示信息,预警提示信息包括紧急预警信息与弱碰撞预警信息。本申请的技术方案能够提高碰撞预警的准确性有效降低目标的碰撞风险。
