基于Hough变换的重磁数据线性特征提取技术
|
摘要
利用重磁数据确定地质体的边界是地质解释中一项很重要的工作,然而目前众多的边界识别方法均基于各种导数变换的组合,因此对噪声的影响比较敏感。基于上述问题,研究分析了图像处理中提出的Hough变换的原理,提出利用该变换进行重磁数据处理,基于此识别数据中包含的线性特征,对应于地质体边界和断裂构造平面展布特征等信息。理论模型和实际数据的计算分析表明,该方法能够较准确地提取出重磁数据边界信息,同时具有较好的噪声鲁棒性。利用Hough变换提取出的线性特征对地质体边界识别、大地构造单元划分及断裂体系分析等工作具有实际的应用意义。
Using of the gravity and magnetic data to determine the boundary of the geological bodies is an important task in geological interpretation.However,most of existing edge detection methods are based on the combination of different derivatives and therefore,they are very sensitive to the noise.For this problem above,this paper analyzes the principle of the Hough transform proposed in the process of digital images,and applies Hough transform to the interpretation of gravity and magnetic data.The linear features extracted from gravity and magnetic data with the Hough transform correspond to different tectonic boundaries and faults.The analysis of theoretical model and actual data shows that this method can extract the boundary information of gravity and magnetic data accurately,andhas better noise robustness compared with the conventional ones.The linear characteristics by using the Hough transform provide practical significance for the identification of tectonic boundaries,the division of tectonic units and the analysis of fracture systems.
