| 摘 要： | 随着地图修测的迫切需要,如何实现影像与地图的精确配准就成为急需解决的问题。虽然多项式模型的配准方法简单直观,但不能满足高精度地图修测的需要。目前影像与矢量图的配准靠人工实现,不容易准确量测,这越来越成为地图修测中全自动空中三角测量的瓶颈。而主动轮廓线模型通过模板自身的弹性形变,与图像局部特征相匹配达到调和,即某种能量函数极小化,从而实现矢量图与影像的精确配准。因此,提出了一种基于B样条Snake模型分割的高精度配准方法。

| Abstract: | Along with the urgent requirement of the map revision,how to achieve precise collocation between the image and the map has become a very important problem that we should resolve.Although the collocation method of polynomial model is very simple and direct,it couldn't meet the need of high precision of map revision.In addition,now we usually carry out the collocation between the image and the vectorgraph manually and it is difficult to measure exactly,so this problem has become a choke point in the process of auto aerial triangulation.However,the active contour model uses template's stretch deformation to attemper the local feature matching on the image.With this method we can achieve the precise collocation between the image and the vectorgraph.Thereby,in this paper,a method of high precision collocation based on the B-spline Snake model is advanced. |
