| 摘 要： | 文中研究了在地图匹配制导了如何提高定位精度的问题，由于数字图像的离散性，传统匹配技术的精度以１个像素的极限，采取对其准图卫片中特征进行亚像元精度特征定位的方法，可以将匹配精度提高到１／３个橡素以内，文中给出了其方法，理论基础，可信性分析和最终的实际匹配结果。

| Abstract: | This paper focuses on improving location precision in image matching . Due to discrete- ness of digital image, precision of traditional matching techniques are limited by one pixel. The loca- tion precision is improved to 1/3 pixel by performing sub - pixel edge detection in fiducial satellite pho- to image. Implementation and theory foundation of the method, as well as the creditability analysis and natural image matching results are provided in the paper. |
