摘 要:图象处理是一门崭新的技术。本文介绍了该技术用于制作线性构造等密度分割图的基本原理和方法以及软件linedensity的设计,井在统计线性构造密度时,定义和运用了“距离系数”的概念。
Abstract: The lineament′s isodensity curves or maps are frequently used in tectonicanalysis and generally carried out by manual method.This paper shows an auto-matic way,utilising the image processing technic.The principles of this automa-tic way are based on the manual method,but it has some advantages,e.g.rapi-dity,exactitude;moreover,the use of the distance coefficients in automaticmethod makes the statistic analysis more representative and more convincing.Asoftware linedensity is so realized by the author in an image processing system PERICOLOR 1000.
