基于目标匹配的道路网增量信息的识别和提取

The Recognition and Extraction of Road Network Incremental Information Based on Target Matching

道路网增量信息的识别和提取方法直接影响地图数据更新的质量,其中提取的阈值是关键。通过面积叠置率结合最大类间方差法计算阈值,实验结果说明该方法有很好的数据针对性,对增量信息提取效果比较好,且算法简单容易实现。

Through the area overlay rate and combined with the maximum between—cluster variance method, this paper calculated the threshold. The experimental results showed that the method had good data relevance and good effect for the extraction of incremental information, and the algorithm was simple and easy to implement.
