基于数字图像处理技术的尾矿坝干滩长度监测

Length Monitoring for Dry Beach of Tailings Dam Based on the Digital-image-processing Technology

通过数字图像处理技术将尾矿坝干滩图像进行二值化处理,使原本复杂的图像变得简单,同时在分辨率允许的情况下,能够最大限度的区分干滩和水面的分界线,然后通过对二值化后的图像进行分析与处理,借助于干滩地标,从而得到准确的干滩长度数据,同时还能达到实时监控,减小不必要的误差。

After the image of the dry beach of tailings dam were converted into binary form by digital-image-processing technology, the originally complex image became simple and helpful to maximum distinguish between dry beach and wa- ter surface line if the resolution was high enough. Then through analyzing and processing the binary image, the exact length of dry beach was obtained by means of dry beach landmark, meanwhile, real-time monitoring was realized to reduce unnecessary errors.
