摘要: 介绍了一种用三角形拟合的措施提取一维曲线的特征进行模式识别的新方法.利用这种方法,把对应的一维曲线处理成波峰凸向y轴正侧的正值曲线,在选取适当割线的基础上,用三角形去拟合曲线的每个波峰.随着割线值的增加,就可以得到若干个不同的三角形集合.一维曲线的特征提取及其模式识别就是在这些三角形集合上进行的.对这种模式识别方法实现的油层自动对比系统的设计和使用情况进行简明阐述.

Abstract: A method for extracting the characteristics of one dimensional curves by trigonometric fitting is now proposed.In the method,there are three steps to be done as following:first,the curves must be transformed into positive curves all the crests of which are to positive side of Y axis,then,each crest of the transformed curves is trigonometrically fitted by using a group of horizontal secants,and a set of triangles is obtained;Finally,the pattern recognition and the characteristics extraction are performed based on the set of triangles.It is also presented how to implement the automatic correlation of pays by the proposed method.Theoretic and experimental results show that the method is very effective.
