摘　　要：仪表示数的自动识别对于自动检测和自动控制具有重要意义,文章以圆盘仪表示数的自动识别为研究内容展开研究。提出了一种基于Snake算法的自动识别方法,整个算法分为Hough变换粗定位圆形特征、Snake算法精定位圆形特征、Hough变换检测直线特征三个环节。此方法以Hough变换检测的圆形特征为初始条件,进而根据Snake模型的内力和外力,引导Snake曲线向更加精确的圆形特征逼近。针对压力表图像展开相应的实验研究,实验结果证实了基于Snake算法的自动识别方法的有效性。Automatic recognition of the number of instruments for automatic detection and automatic control is of great significance, this paper takes the automatic identification of the number of disc instrument as the research content. An automatic recognition method based on Snake algorithm is proposed, and the whole algorithm is divided into three parts： the rough positioning circular feature by using Hough transform, accurate positioning circular feature by using Snake algorithm, and detecting line feature by using Hough transform. By using Hough transform to detect the circular feature as the initial conditions, this method adjusts Snake curve approximation to a circular feature more accurately according to the internal and external forces of the Snake model. According to experimental of the pressure gauge image, the experimental results confirm the validity of the automatic recognition method based on the Snake algorithm.
