| 摘 要： | 提出并实现了二值图像上十字交点的沿线匹配算法，发展了一种根据相关位置自动识别图廓点，进而计算图像坐标系和大地坐标系之间变换参数的方法，实现了地图定向的自动化。实验表明，文中所述的地图定向方法在提高自动化程度的同时，也提高了地图定向的精度。

| Abstract: | In this paper, the algorithms of line-matching of filar cross on binary images are proposed. The approaches to automated recognition of map marginal points and calculation of transformation parameters between geodesic and image coordinates are also developed. Experiments show that the automated map orientation is realized and the accuracy of orientation is also raised with the method proposed in this paper. |
