摘要:

为了使联网车辆对道路安全产生实质性影响,需要能够共享准确的位置和轨迹。为此,所有车辆都必须在一个共同的框架内准确定位。这可以通过将GNSS(全球导航卫星系统)信息和视觉观测与地理定位地标地图相匹配来实现。建立这样一个地图仍然是一个挑战,目前的解决方案面临着与成本有关的严重限制。我们提出了一个高清晰度地图的协作框架,其中配备有标准传感器的车辆,如GNSS接收器和单视觉相机,更新地理定位地标的地图。我们的系统是由两个处理块:第一个是嵌入在每个车辆,并在地理定位的车辆和检测到的特征标记的目的。第二个是在云服务器上运行的,并使用来自所有车辆的观察来计算地理定位地标地图的更新。随着地图的地标被越来越多的车辆检测和定位,地图的准确性增加,最终在概率上朝着零误差收敛。地标地理位置以稳定和可扩展的方式估计,从而能够以自动方式提供动态地图更新。

英文摘要:

For connected vehicles to have a substantial effect on road safety, it is required that accurate positions and trajectories can be shared. To this end, all vehicles must be accurately geolocalized in a common frame. This can be achieved by merging GNSS (Global Navigation Satellite System) information and visual observations matched with a map of geo-positioned landmarks. Building such a map remains a challenge, and current solutions are facing strong cost-related limitations. We present a collaborative framework for high-definition mapping, in which vehicles equipped with standard sensors, such as a GNSS receiver and a mono-visual camera, update a map of geolocalized landmarks. Our system is composed of two processing blocks: the first one is embedded in each vehicle, and aims at geolocalizing the vehicle and the detected feature marks. The second is operated on cloud servers, and uses observations from all the vehicles to compute updates for the map of geo-positioned landmarks. As the map's landmarks are detected and positioned by more and more vehicles, the accuracy of the map increases, eventually converging in probability towards a null error. The landmarks geo-positions are estimated in a stable and scalable way, enabling to provide dynamic map updates in an automatic manner.
