中文摘要：
针对道路网线要素特点,提出了基于投影的道路网信息几何匹配方法。根据线段斜率,对线段进行投影、分割,提取线要素特征点,将复杂的道路网匹配转化为特征点匹配,可解决复杂的多对多匹配。通过渐进式的匹配策略,逐步、快速缩小匹配范围,提高了匹配效率。通过实验合理地调整匹配阈值,减少漏匹配与误匹配,提高整体匹配准确率。结果表明,本算法效率高,可靠性好,符合应用需求。
英文摘要：
This paper puts forward a geometry matching method for transportation road net- work data based on projection. Characteristic points can be extracted from lines by projection and segmentation, so complex matching of road networks is converted into a characteristic point matching problem. An incremental matching strategy was designed, that narrows the range of matching and improves matching efficiency. A proper matching threshold can not only reduce leakage match and mismatch but also improves matching accuracy. Experimental results show that this method can obtain ahigher correct matching rate that meets application requirements.
