The invention discloses a collision early warning method and device based on recognition of obstacles in front of a vehicle. The method comprises the following steps of: obtaining a real-time video of an object in front of a target vehicle, and judging a regional target related to and obstructing the target vehicle in an environment through the analysis of a video image; constructing a static and dynamic judgment condition set; judging whether the target vehicle enters a dangerous area or not according to a judgment condition, if the target vehicle enters the dangerous area, prompting that the probability of the collision accident tends to be determined, and otherwise, analyzing and calculating the probability of the collision accident; and according to a probability judgment result, advancing collision early warning sending time, intelligently taking corresponding danger avoiding measures for the target vehicle or making a driver of the target vehicle take the corresponding danger avoiding measures. According to the method and device of the invention, on the basis of vehicle detection and tracking, and the behavior of a front vehicle, the collision early warning sending time is advanced, danger assessment is carried out on the surrounding environment of the vehicle, and the driver can take the corresponding danger avoiding measures in time,.

    本发明公开了一种基于车辆前方障碍物识别的碰撞预警方法及其装置,方法包括如下步骤:获取目标车辆前方的物体实时视频,通过对该视频图像分析,判断环境中与目标车辆相关妨碍的区域目标;构建静态和动态判断条件集合;利用判断条件判断目标车辆是否进入危险区,如果进入则提示车辆发生碰撞事故的概率趋向于确定,如未进入则分析计算发生碰撞事故的概率;根据概率判断结果,提前碰撞预警发出时间,对目标车辆智能采取相应避险措施或使目标车辆驾驶员及时采取相应避险措施。本发明,在车辆检测与跟踪的基础上,对汽车周围环境进行危险评估,并结合前方车辆行为,提前碰撞预警发出时间,使驾驶员及时采取相应避险措施。
