The invention relates to a road speed limit information fusion judgment method, which mainly comprises the following steps of: 1) obtaining an SC speed limit value from speed limit board information obtained by a camera, and obtaining a Map speed limit value from positioning information obtained by a navigation map; 2) judging whether the SC speed limit value and the Map speed limit value are effective or not according to the positioning information and a preset speed limit value range; and 3) judging whether the corresponding SC speed limit value is valid or not according to the speed limit board information, judging whether the corresponding Map speed limit value is valid or not according to the positioning information, and then further judging and outputting. According to the invention, the camera and the navigation map are adopted to obtain the speed limit value of the road at the same time, and the obtained speed limit values are subjected to speed limit range validity judgment, speed limit board information validity judgment, positioning information validity judgment and fusion judgment and then output; therefore, the problems that an existing road speed limit value obtaining and judging method is inaccurate in recognition and poor in reliability are solved, and the effect that the reliability of the automatic driving system is high is achieved.
本发明涉及一种道路限速信息融合判断方法,主要步骤如下:1)从摄像头获取的限速牌信息中得到SC限速值,从导航地图获取的定位信息中得到Map限速值;2)根据定位信息和预设限速值范围判断SC限速值和Map限速值是否有效;3)根据限速牌信息判断对应的SC限速值是否有效,根据定位信息判断对应的Map限速值是否有效,然后进一步判断输出。本发明同时采用摄像头和导航地图获取道路的限速值,对两者获取的限速值进行限速范围有效性判断、限速牌信息有效性判断、定位信息有效性判断和融合判断后输出,从而解决目前获取道路的限速值及判断的方法存在识别不准确、可靠性较差的问题,取得高自动驾驶系统可靠性的效果。
