Abstract

Drill core is very important for researchers to study lithospheric structure. However, how to save cores in good condition as well as how to satisfy the need of studying drill cores anytime and anywhere as we want are big questions. Thus, numerical images of drill cores are very necessary. Hyperspectral images have lots of advantages, for they can provide both true color images and hyperspectral messages. True color images can be used for direct observation and study. And hyperspectral messages can be used for mineral identification. In practical use, there are distortions in the scanned hyperspectral images, so correction method is in great need. A geometric and luminance correction method is raised in this paper, and results show that the correction method works well. For the sake of observation, three-dimension display is more convenient. This paper provides an implementation method of 3D display. At last, this paper provides a method for extracting mineral alteration data. Through the methods above, hyperspectral images are useful and feasible in the digital record of drill cores.
