| 摘 要： | 针对现有的矢量地图修改检测方法计算速度慢、效率低等问题,设计利用Bayes判别分析进行地图修改检测的方法。首先对同一幅修改前后的矢量地图分别进行栅格化,并进行配准;然后利用Bayes判别分析方法对配准后的栅格图像进行变化检测,获得矢量地图的修改区域;最后将修改区域与审校结果进行对比,发现错修改和漏修改问题。实际矢量地图数据的修改检测实验结果验证了利用Bayes判别分析方法实现地图修改检测的有效性和可行性。

| Abstract: | Aiming to the problem of heavy running time performance in the common used method for modification detection between vector maps,a method based on Bayes is proposed.First,the unmodified and modified vector maps are put into the grid images and the registration.Then the change detection for grid images is done in order to achieve the modified region.Finally,the problems of inaccurate modification and missed modification are pointed according to the comparison between the modified region and examing results.The experimental result of modification detection for real vector map proves the validity and practicability of the proposed method. |
