基于主动轮廓线模型的道路矢量与影像配准研究

An ACM-Based approach for conflating road vector data with imagery

针对道路矢量与影像空间位置不一致的问题,提出了基于主动轮廓线模型的道路矢量与影像配准方法.此方法利用主动轮廓线模型使道路矢量向影像上的道路特征移动逼近,实现了先验信息匮乏情况下的道路矢量与影像的自动配准,为提高影像地图生产效率提供了一种有效的技术手段.

For solving the inconsistencies between the road vector data and imagery, this paper proposed an active contour model （ACM） based approach for conflating road vec- tor data with imagery. The road vector can be driven to the imagery by ACM deforma- tion. The proposed approach can make the conflation without enough prior information about roads and provide an applicable technology for improving the efficiency of image map production.
