The invention relates to a collision early warning method and device, computer equipment and a storage medium. The collision early warning method comprises the steps that a real-time image behind a vehicle and electronic rearview mirror system delay are acquired; if the lane changing request exists at present, determining a moving target in the real-time image and the relative distance and the relative speed of the moving target relative to the vehicle according to the real-time image; according to the relative distance, the relative speed and the electronic rearview mirror system delay, the collision time is determined; collision early warning is carried out according to the collision time; the accuracy of the collision time is improved, the reliability of collision early warning is further improved, further, based on collision early warning, the driving risk is reduced, and the driving safety of the vehicle is improved.

    本申请涉及一种碰撞预警方法、装置、计算机设备及存储介质,碰撞预警方法包括:获取自车后方的实时图像以及电子后视镜系统延迟;若当前存在换道请求,则根据实时图像,确定实时图像中的移动目标以及移动目标相对于自车的相对距离以及相对速度;根据相对距离、相对速度以及电子后视镜系统延迟,确定碰撞时间;根据碰撞时间进行碰撞预警;提高了碰撞时间的准确性,进而提高了碰撞预警的可靠性,进一步,基于碰撞预警,降低了行车风险,提高了自车行车的安全性。
