The invention provides a vehicle safe driving method and system based on a safe traffic sign. The method comprises the following steps: generating a safety traffic sign by embedding digital watermark information in a common traffic sign image; in the driving process of a vehicle, while collecting the image information of the traffic sign, collecting the geographic position information of a vehicle end at the same time; in the judgment and error correction stage of the safety traffic sign, judging whether the image of the safety traffic sign is illegally altered and tampered or not based on the digital watermark information, and comparing the geographic position information of the vehicle end with the geographic position information of the safety traffic sign contained in the digital watermark information; therefore, the problem of judgment and error correction of the safety traffic sign image after the placement position is incorrect or the safety traffic sign image is illegally moved is solved, and therefore the problem that when the safety traffic sign is incorrect in placement position or illegally moved, an automatic driving automobile malfunctions in a place or a road section where an action should not be taken is avoided.

    本发明提供一种基于安全交通标志的车辆安全驾驶方法及系统,通过在普通交通标志图像内嵌入数字水印信息从而生成安全交通标志,车辆在行驶过程中,采集交通标志的图像信息时,同时会采集车辆端的地理位置信息,在安全交通标志的判断勘误阶段,不仅要基于数字水印信息判断安全交通标志图像是否被非法涂改、篡改,也要比对车辆端的地理位置信息和数字水印信息内包含的该安全交通标志所要安放的地理位置信息,以解决安放位置不正确或被非法移动位置后的安全交通标志图像的判断勘误问题,从而避免了自动驾驶汽车在安全交通标志安放位置不正确或被非法移动位置时,在本不应该采取动作的地点或路段出现误动作的问题。
