The invention discloses a signalized intersection pedestrian crossing safety early warning method and system facing automatic driving. The method comprises the following steps: acquiring real-time video data; performing pedestrian detection on the real-time video data by adopting a YOLOv9 model to obtain a pedestrian bounding box; performing optimization processing on the pedestrian bounding box by adopting a non-maximum suppression method to obtain a target bounding box; performing view angle conversion on the image of the target bounding box, and calculating to obtain longitude and latitude information of the pedestrian; determining advancing information of pedestrians according to the longitude and latitude information; and calculating safety information of the pedestrian according to the advancing information, and generating a pedestrian early warning signal corresponding to the safety information. The method improves the safety and reliability, can achieve the precise detection and positioning of pedestrians, enhances the safety guarantee of the pedestrians at the intersection, reduces the possibility of traffic accidents to the minimum, and can be widely used in the technical field of intelligent transportation.

    本发明公开了一种面对自动驾驶的信号交叉口行人过街安全预警方法及系统,方法包括:获取实时视频数据;采用YOLOv9模型对所述实时视频数据进行行人检测,得到行人边界框;采用非极大值抑制的方法对所述行人边界框进行优选处理,得到目标边界框;对所述目标边界框的图像进行视角转换,计算得到行人的经纬度信息;根据所述经纬度信息确定行人的行进信息;根据所述行进信息,计算行人的安全信息,并生成所述安全信息对应的行人预警信号。本发明提高了安全性和可靠性,能够实现精确地检测和定位行人,增强交叉口行人的安全保障,并将交通事故的可能性降至最低,可广泛应用于智能交通技术领域。
