The invention provides an upright post blind area traffic accident early warning method and system, and the method comprises the steps: collecting a video of an upright post blind area through a camera when a first road where the upright post blind area is located is red, inputting the video into a target detection model, and detecting whether a to-be-detected target exists in the upright post blind area; constructing a coordinate system for a column blind area in the video, positioning a to-be-detected target through the video and a sensor under the condition that the to-be-detected target is detected in the column blind area, and calculating the speed and acceleration of the to-be-detected target; according to the speed and the acceleration of the to-be-detected target and the distance between the to-be-detected target and the second road, the danger degree is obtained through comprehensive evaluation, and under different danger degrees, different early warnings are given to vehicles on the second road. By positioning the target and calculating the speed and the acceleration, the danger degree of the target is accurately pre-judged, traffic accidents caused by the fact that pedestrians are located in a blind area are effectively avoided, and the safety of traffic participants is guaranteed.

    本发明提供了一种立柱盲区交通事故预警方法及系统,在立柱盲区所在第一道路为红灯的状态下,通过摄像头采集立柱盲区的视频,将视频输入目标检测模型,检测立柱盲区内是否有待测目标;对视频中的立柱盲区构建坐标系,在检测到立柱盲区内有待测目标的情况下,分别通过视频以及传感器对待测目标进行定位,计算待测目标的速度、加速度;根据待测目标的速度、加速度以及与第二道路的距离,综合评估得到危险程度,在不同的危险程度下,对第二道路上的车辆进行不同的预警。本发明通过对目标进行定位以及速度、加速度的计算,从而准确预判目标的危险程度,有效避免因行人处于盲区而引发的交通事故,保障了交通参与者的安全。
