中文摘要: 利用经过截取处理的欧亚范围的欧洲格点数据,通过运算转化为屏幕网格资料,采用逐点追踪方法绘制等压线,运用统计识别法和模糊识别技术,结合实测风场订正,对高低压中心和槽线进行分析识别。试验结果表明,计算机能基本准确的识别出高低压中心及槽线,且速度比人工快得多,从而可做为人工智能工作站的一个接口,并为天气图的客观化和自动化分析作了初步尝试。
中文关键词: 图形识别,高低压中心,槽线
Abstract:Europe-Asia regional grid data is prepared and convered into computer screen grid data. By calculation,contour lines are drawn up. And then,high pressure centres and low pressure centres and trough-lines are determined with statistical recognition and fuzzy recognition technology,and reduced with wind observation. Test suggests that a connection of artificial intelligence work station could be made.
