摘　　要：针对长期以来尾矿库干滩长度测量方法的局限性,提出一种新的利用图像处理技术进行尾矿库干滩长度测量的方法。此方法首先通过视觉显著性结合区域形状分析的方法来获取标志杆在图像中的坐标,然后通过区域生长算法在图像中提取干滩区域,最后利用射影变化中共线四点的交比不变性来计算干滩长度。通过实际测量实验,所提方法具有实施方便,测量误差小的特点,因此其具有较高的应用价值。As the measuring method of dry beach length of tailings pond has the limitation for a long time,a new measuring method of dry beach length of tailings pond is proposed and realized by the image processing technology.In this method,the coordinate of marker rods in the image is obtained by means of the method combining visual saliency with regional shape analysis,then the dry beach region is extracted from the image by means of the region growing algorithm,and finally the length of dry beach is calculated by using the invariance of cross ratio of collinear four points in the projective variation.The actual measured results in the experiment show that this method has the characteristics of convenient implementation and small measurement error.Therefore,it has high application value.
