对高精度仪表自动判读方法进行了研究，研究过程主要分为三个部分。首先，根据视差形成原理分析了低精度仪表自动判读方法镜头的正确位置。接着，分析了采用低精度仪表自动判读方法对高精度仪表进行自动读数时，引入误差会增大高精度仪表的读数误差。最后，提出了一种采用图像处理技术及伺服跟踪技术相结合高精度模拟仪表读数自动识别的方法。实验结果表明，这种方法非常适宜于高精度仪表自动判读。

In the paper, a method for the recognition of high-precision meters is researched. The research process consists of three main phases. Firstly, based on the principle of parallax formation, the paper analyzes the right camera lenses position of the automatic recognition method of low-precision meters. Secondly, it is shown through the analysis that importing error will increase reading error when the automatic recognition method of low-precision meters is used to recognize the reading of high-precision meters. Finally, the paper presents a kind of method of automatic recognition for high-preci...
