【摘要】 本文在简单介绍指针式仪表及其常用识别方法的基础上,提出了一种基于最大灰度相减法的新型识别方法。然后详细介绍了这一方法的工作过程,着重阐述了几个关键环节所用到的图像处理算法。最后,给出了试验的结果及分析,指出了优化的途径。更多还原

【Abstract】 This paper,based on the theory of pointer meters and standard recognize technique. issued a new recognize technique,which was ground on the maximum gradient comparing subtraction method. The function process of this new technique was introduced by elabo-rating certain arithmetic of the key segments of the very method. Furthermore,some experiment results as well as the analysis demonstrate the optimization strategy.更多还原
