摘要
对露点仪镜面过冷水产生的原因及其对露点测量准确度的影响进行分析,采用图像处理方法对露点仪镜面上的过冷水进行自动识别,经过计算机处理,修正了因露霜判别错误引入的误差,提高了露点测量的准确度和自动化程度。
The reason generating the over-cooling water on the mirror of the dew point hygrometer and its influence on the measure accuracy was analyzed, and the over-cooling water is discern automatically by the pattern process method. The error introduced by the mistaken judgement of the dew and frost can be accurately revised through the computer process and the accuracy and the automatic degree of the dew point hygrometer can be improved.
