Road positioning mark serving unmanned vehicle

Abstract

The invention relates to a road positioning mark serving an unmanned vehicle, a color block array with a simple geometrical shape is used for representing unique and accurate road geographic position information, accurate positioning information is provided for the unmanned vehicle, data bits are represented through the color block array, and camera recognition and image processing are easy; the geographic position information represented by the road positioning mark provided by the invention is unique geographic information based on global positioning, and is more applicable compared with a road identifier based on a relative geographic position in the prior art; compared with a standing type or suspension type road positioning mark in the prior art, the road positioning mark provided by the invention is small in size, can be assembled and laid on the road ground, is small in occupied area, facilitates image acquisition and road construction, and can reduce the production and installation cost. 本申请一种为无人驾驶车辆服务的道路定位标识，使用具有简单几何形状的色块阵列表示唯一准确的道路地理位置信息，为自动驾驶车辆提供准确的定位信息，通过色块阵列表示数据位，易于摄像头识别和图像处理；本发明提供的道路定位标识表示的地理位置信息为基于全球定位的唯一的地理信息，相比较于现有技术的基于相对地理位置的道路标识更适用；区别于现有技术的站立式或悬挂式的道路定位标识，本申请提供的道路定位标识尺寸小，可装配铺设在道路地面上，占路面积小，方便了图像获取和道路施工，可降低生产和安装成本。
