摘要
根据煤层与岩石层分界明显且呈线状的煤岩图像特征,提出一种基于Hough变换的煤岩界面识别方案。首先对煤岩图像进行去噪与增强预处理,然后去除煤与岩石边缘的孤立点与虚假边缘,最后采用Hough变换识别煤岩分界线。实验结果表明,该方案能够较快、较准确地检测出煤岩分界线。
A coal-rock interface identification scheme based on Hough transform was proposed according to characteristic of coal-rock image,namely boundary between coal seam and rock seam is significant and linear.Coal-rock image is pre-processed firstly by denoising and enhancing.Then isolated points on coal-rock edge are removed as well as false edges.Finally,Hough transform is used to identify coal-rock interface.Experimental result shows that the scheme can detect coal-rock boundary fast and correctly.
