摘要: 针对纸制军事地图等高线的提取问题,运用图像处理、色度分析学和模式识别等理论,分析了扫描地图数据产生颜色误差的原因,并根据各颜色空间的模型特点,讨论了色彩空间转换的必要性.先用最大方差自动取阈法得到地图黑色要素层的单版图,再对阈值分割后的图像进行C-均值聚类,得到等高线(棕色要素)单版图,最后得到了分离的等高线图层.实验研究表明了方法的可用性和有效性.

关键词: 等高线, RGB模型, HSV模型, 阈值分割, 聚类

Abstract: To pick up directly the contours on a military map made from paper, such theories as image segmentation, chroma analysis and mode identification are applied to analyzing the causes of color error in the data by map scanning. According to the characteristics of the model of each color space, the necessity of color space transformation is discussed and the method of the image segmentation is presented. Experiment results show the effectiveness of the proposed method.
