摘要
分析了图纸存档与通信系统中传统图纸输入的两个关键技术 :大幅面图纸的扫描自动拼接和不均匀背景的消蓝。采用标记匹配方法实现自动拼接 ,采用形态学滤波和四阶中心矩方法实现不均匀背景图纸的的消蓝 ,提高了图纸输入的效率和质量。
We study two key technology of traditional drawing input in drawing archiving and communication system that is the automatic joint of scanned large drawings and the wiping blue with inconsistent background. Maker-matching method used in automatic joint, while morphologic filter and fourth central moment method are used in wiping blue. These methods improve the efficiency and the quality of drawing input.
