| 摘 要： | 本文分析了电子水准仪的测量原理,提出了水准标尺的条码结构,在此基础上提出了采用基于指数基的快速边缘检测算法对水准标尺条码图像进行边界提取。实验结果表明,采用该算法提取条码边界,大大降低了数据处理的运算量,有效地抑制了随机噪声的影响,能精确地检测出条码边缘位置。

| Abstract: | The measurement principle of electronic level is anal- ysed in this paper. The bar structure of level gauge is present- ed. The edge signal of bar image from level gauge is detected with the speedy edge detection algorithm which is based on ex- ponential radix. The experiment result indicates that the quantity of calculation is remarkably decreased. The effect of random noise is effectively inhibited and bar edge position is detected exactly. |
