一种岩石薄片全幅面采集新方法

A new method for full-area acquisition technology of rock thin sections

传统岩石薄片图像采集是在观察薄片的基础上,选择有代表性的位置进行图像采集,虽然具有一定的典型性和代表性,但也有观察人员的主观性和随机性,不能反映出整张薄片的性质。自然资源实物地质资料中心开展的全幅面采集,是对岩石薄片整张全自动采集,包括自动移动、自动聚焦、自动拼接等,图像采集过程区别于常规显微图像采集方式,是实物薄片信息采集、保存、分析的革命性新方法,满足了实物地质资料数字化的原始性、真实性、完整性,采集到的图像还适用于薄片矿物分析、粒度分析及回溯性鉴定、专题研究等。

Traditional image collection of rock thin section is based on the observation of thin slices to select representative points to collect image preservation.Although it is typical and representative,it also has subjectivity and randomness of the observer.It is difficult to reflect the character of full-area of rock thin section.Full-area acquisition of rock thin sections is a full automatic collection of rock slices,including automatic movement,automatic focus,automatic splicing,etc.It is carrying out by Cores and Samples Center of Natural Resources.The image acquisition process is different from the conventional microscope image acquisition method.It is a revolutionary new method for collecting,saving and analyzing rock thin sections,which satisfies the originality,authenticity and integrity of digitalization of geologic information.These images are also suitable for thin mineral analysis,particle size analysis,retrospective identification and special research.
