摘要: 利用彩色扫描图形数字化处理技术实现降水自记纸图形的数字化处理是对气象历史档案拯救技术的有效探索。该文从降水自记纸扫描图形的数字化精度分析和彩色扫描的优势特征分析出发，重点研究分析了存储方式、降水曲线彩色表征区分技术和降水自记纸扫描图形数字化数据处理技术，用以为其它图形数字化处理提供一种技术思路和有效的技术参考。Abstract: The digitizing processing of precipitation recording graph using the technology of color scanning graph is an effective test for rescuing historic meteorological archives. According to the precision analysis of digitizing precipitation recording graph and the features of color scanning, the research of processing technology of data access mode, distinguishing precipitation curve color and data processing are stressed to explore. The processing method of precipitation recording graph may furnish a thinking way and reference to other digitizing graph processing.
