改进的曲率计算方法及其效果分析
摘要
Abstract
The curvature is usually calculated by using least square method to approximate the local curved surface with 3*3 grid unit. The method brings in a lot of noise, so some of the micro structures are covered by noise and cannot be displayed. Therefore, we utilized the least square method to approximate the local curved surface by5*5 grid unit and 7*7 grid unit and derived detailed calculation formula. The application results on actual data indicate that the a-bility of resisting noise is enhanced,and the characteristics of faults and some micro structures can be distinguished effectively, which proves the correctness of the curvature formula obtained by 5 * 5 grid unit and 7*7 grid unit.关键词
