Methods, systems, and techniques for validating road intersections are presented. The method includes receiving annotated intersection data that, for each lane of a particular candidate intersection, indicates one or more attributes of the lane; processing the annotated intersection data to generate an intersection fingerprint for the particular candidate intersection that is sensitive to a topological structure of the lanes of the particular candidate intersection and is invariant to a geometry of the lanes of the particular candidate intersection; designating the particular candidate intersection as validated without performing the one or more quality control processes based at least on the intersection fingerprint; and storing a representation of the particular candidate intersection in the roadgraph.
呈现了用于验证道路交叉口的方法、系统和技术。所述方法包括:接收带注释的交叉口数据,该带注释的交叉口数据针对特定候选交叉口的每个车道指示车道的一个或多个属性;处理带注释的交叉口数据以生成针对特定候选交叉口的交叉口指纹,该交叉口指纹对特定候选交叉口的车道的拓扑结构敏感并且对于特定候选交叉口的车道的几何结构是不变的;至少基于交叉口指纹来将特定候选交叉口指定为经过验证,而不执行一个或多个质量控制过程;以及将特定候选交叉口的表示存储在道路图中。
