The invention discloses a high-precision map centimeter-level positioning method and a high-precision map centimeter-level positioning system for an intelligent networked automobile, and relates to the technical field of automobile positioning. Matching the bar code combination corresponding to the extracted target image with the bar code sequence data of each lane of the target road section, determining the current lane of the target intelligent network connection automobile, and determining the number of complete bar codes according to the camera parameters of the camera on the intelligent network connection automobile and the bar code sequence data of the target lane; the current displacement of the bar code at the current moment is determined, and finally the final centimeter-level positioning information is determined according to the number of the complete bar codes at the current moment and the current displacement, so that high-precision centimeter-level precision positioning of the intelligent networked automobile can be realized in special scenes such as urban canyons, long-distance tunnels and multi-layer interchange where GNNS positioning is difficult.
本发明公开一种智能网联汽车高精度地图厘米级定位方法及系统,涉及汽车定位技术领域,该方法首先对当前时刻目标图像中的条码信息进行提取,然后将提取到的目标图像对应的条码组合与目标路段的每一车道的条码序列数据进行匹配,确定目标智能网联汽车当前所在车道,然后根据智能网联汽车上相机的相机参数以及目标车道的条码序列数据确定完整条码的数量,并确定在当前时刻所属条码的当前位移,最后根据当前时刻完整条码的数量以及当前位移确定最终的厘米级定位信息,可在城市峡谷、长距离隧道、多层立交等GNNS定位困难的特殊场景下,实现智能网联汽车高精度的厘米级精度定位。
