纸面记录曲线的数字化方法

New Method for Digitizing Paper-based Testing Curves

对以往试验的纸面记录曲线进行数字化处理,取出尚未提取的大量珍贵信息,具有实际意义。提出利用扫描仪把纸面记录曲线转化为数字图像,然后运用图像识别的方法对纸面记录曲线进行自动化处理,把数字图像中的曲线数据及标定信息识别出来,再对提取的数据进行分析计算并得出结果。提出了关键问题的解决方法。

A new method to record testing curves digitally on paper was proposed which could extract more information than that by an analog scanner. In the method we firstly obtain an image of paper-based testing curves by an analog scanner, and then the paper recorded curve was recognized and extracted by a self-developed computer program. The solutions of some key problems encountered in applications were put forward. The method proved to be efficient by practical applications.
