摘要
本文介绍针对地质图像特殊性来用的空间运算和逻辑运算方法，把“非”、“与”、“或”、“异或”等 常用逻辑运算和数学形态学中的“膨胀”、“剥蚀”、“断开”、“闭合”等空间运算方法引入到地质图像处 理中，并进行若干技术改进，以用于对不同地质特征空间逻辑关系的分析。在地质图像处理基础上， 提取了可供显示、观察和找矿分析的地质变量，对湖南香花岭地区多金属矿进行预测．取得初步效果。
The methodology of several new image processing techniques which are directed against the particularity of geological image is presented in this paper. Especially, the Logic Operations including Nothing. Anding. Oring and Exclusive Oring, and the Spatial Operations which include Dilation. Erosion. Opening' and Closing in Mathematical Morphology have been introduced into geological image processing. Additionally, several technical improvements have been made in terms of the special requirements of geological image processing for the analyses of spatial/logic relationships between different geological features. Based on geological image processing, various geological variables have been extracted for displaying, image processing and mineral exploration. Finally, the W-Sn-Pb-Zn multiple mineral deposits have been predicted in Xinghualing region, Hunan province, China, according to parts of the geological variables extracted from multi-geoscience information including geological, structural, mineral deposit, alteration, geophysical and geochemical data, and the primary result of mineral prediction is achieved.
