The invention provides a vehicle collision early warning method and system, and the method comprises the steps: obtaining a first road image and a second road image in front of a target vehicle, and carrying out the preprocessing of the images, and obtaining a first road processing image and a second road processing image; identifying and extracting a first image coordinate and a second image coordinate of the obstacle vehicle; calculating a first longitudinal distance and a first transverse distance between the target vehicle and the obstacle vehicle, and judging whether the obstacle vehicle has a lane changing intention or not; if yes, a second longitudinal distance is calculated, and whether the second longitudinal distance is smaller than a preset safety distance or not is judged; if the lane changing intention does not exist, whether the first longitudinal distance is smaller than the preset safety distance or not is judged. The vehicle collision early warning method can be suitable for vehicle collision early warning in a complex environment, the safety of the target vehicle in the driving process is further ensured, and the risk of vehicle collision is reduced.

    本发明提供了一种车辆碰撞预警方法及系统,所述方法包括:获取目标车辆前方的第一道路图像与第二道路图像,对其进行预处理得到第一道路处理图像与第二道路处理图像;识别并提取障碍车辆的第一图像坐标与第二图像坐标;计算所述目标车辆与所述障碍车辆之间的第一纵向距离与第一横向距离,并判断所述障碍车辆是否有变道意图;若有变道意图,则计算第二纵向距离,并判断所述第二纵向距离是否小于预设安全距离;若无变道意图,则判断所述第一纵向距离是否小于所述预设安全距离。本发明可适用于复杂环境下的车辆碰撞预警,进一步确保了目标车辆行驶过程中的安全性,降低了汽车碰撞的风险。
