The invention relates to the technical field of intelligent transportation, and particularly discloses an intersection safety early warning system based on machine vision and DSRC and an early warningmethod thereof, and the system comprises an image collection unit which is used for collecting an intersection image; an image processing unit, connected with the image acquisition unit and used fordetecting, positioning and tracking the target to obtain the walking direction, position and speed of the target; wherein the targets comprise pedestrians and vehicles; a central data processing unitconnected with the image processing unit and used for analyzing the situation of the target, carrying out safety boundary calculation, predicting whether the target collides with the vehicle or not and sending out real-time alarm information if the target collides with the vehicle; and a DSRC communication unit connected with the central data processing unit and used for information interaction between the vehicle and the central data processing unit. Early warning can be provided for passing vehicles according to the road condition of the intersection, driving of a driver is facilitated, andmeanwhile the safety of the intersection is improved.

    本发明涉及智能交通技术领域,具体公开了一种基于机器视觉与DSRC的交叉口安全预警系统及其预警方法,该系统包括:用于采集交叉口图像的图像采集单元;与图像采集单元连接,用于对目标进行检测定位与跟踪,获得所述目标的行走方向、位置和速度的图像处理单元;所述目标包括行人和车辆;与图像处理单元连接,用于对目标的态势进行分析,并进行安全边界计算,预测是否会与车辆发生碰撞,若会产生碰撞,发出实时报警信息的中央数据处理单元;与中央数据处理单元连接,用于车辆与中央数据处理单元之间的信息交互的DSRC通信单元。本发明可以根据交叉路口的路况,对过往车辆提供预警,方便司机驾驶,同时提高交叉路口的安全性。
