| 摘 要： | 文章提出了一种改进的穿线检测图像分割方法,用于对指针式电测仪表表盘图像的分
割。该方法充分利用目标图像的几何特征,将图像的每行(列)按照一定的阈值进行分段并计算出最大分段的长度,通过对图像进行行(列)扫描分析最大分段长度的变化规律来确定分割点,克服了传统穿线检测法对图像质量要求较高的缺点。实验结果表明该方法的图像分割质量非常好。

| Abstract: | In this paper an improvedmethod of image segmentation based on threading detection is present. Themeth-od is used to segment the image of dial of the electricmeasuring instrument. Themethodmakes use of the geometrical
characteristic of the object. The line ( row) of image is segmented by a threshold value, and the length of the biggest subsection is calculated. The segmentation points are found through analyzing the change of the biggest subsection.Thismethod overcomes the shortcoming that the demand to the quality of image is too strict. The experimental result shows that the effect of the method is very good. |
