摘要: 为了测评导航电子地图道路质量的需要,提出了一种自动对比分析多源导航电子地图道路的方法。该方法首先提取导航电子地图的道路网,然后通过基于缓冲区分析的算法自动检测不同数据源道路网之间的差异,最后采用基于Shi-Tomasi算子提取道路交叉点并统计道路段数,实现了定量对比分析多源导航电子地图道路。试验表明本文方法能够有效自动对比分析多源导航电子地图道路。

Abstract: In order to evaluate the quality of the road in navigation electronic map,a method of automatic comparison and analysis of road in multi-source navigation electronic map is proposed.Road networks are automatically extracted firstly,and difference between the road networks in multi-source navigation electronic map is detected using algorithms based on buffer analysis.Intersections of road are detected afterwards using Shi-Tomasi operator and the number of road is count,which realizes quantitative comparison and analysis of multi-source navigation electronic map.Experiments have proved the effectiveness of this method.

Key words: navigation electronic map, road, buffer analysis, difference detection, road intersection
