The invention relates to the technical field of traffic safety, in particular to a road safety early warning method based on multi-sensor fusion and a computer vision technology. The method comprises the following steps: respectively generating a position initial Boolean value and a speed initial Boolean value based on data of a current target object, and obtaining a weighted Boolean value by the position initial Boolean value and the speed initial Boolean value through a weighting algorithm; object and lane line detection is carried out on the current target object image, obstacles and lane lines are identified, and the driving direction and speed of the current target object at the next moment are predicted; obtaining a final fusion speed of the current target object based on the measurement speed, the simulation speed and the prediction speed at the next moment; and generating a standard driving Boolean value according to the type of the target object, the final fusion speed, the predicted driving direction and the positioning and position information, evaluating the collision danger level through the standard driving Boolean value and the weighted Boolean value, and generating a corresponding early warning signal. The road safety early warning comprehensiveness and accuracy are improved.

    本发明涉及交通安全技术领域,尤其涉及一种基于多传感器融合和计算机视觉技术的道路安全预警方法。本发明基于当前目标对象的数据,分别生成位置初始布尔值与速度初始布尔值,位置初始布尔值与速度初始布尔值通过加权算法得到加权布尔值;对当前目标对象图像进行物体和车道线检测,识别障碍物和车道线,并预测当前目标对象下一时刻行驶方向与速度;基于测量速度、模拟速度以及下一时刻预测速度,获取当前目标对象的最终融合速度;根据目标对象的类型、最终融合速度、预测行驶方向、定位与位置信息,生成规范行驶布尔值,通过规范行驶布尔值与加权布尔值,评估碰撞危险等级,并生成相应的预警信号。本发明提高了道路安全预警全面性与准确性。
