Problems solved by technology

However, due to the wide variety of minerals in rock ore samples, the gray scale of many minerals is very close to each other after graying the color picture through binarization, which makes it difficult to distinguish the accuracy of mineral identification.
Therefore, so far, there is no successful development of a processing system for mineral microscopic images with good application effects.

Abstract

The invention discloses an automatic identification method for optical microscopic images of metal sulfide minerals. The prepared rock and mineral sample light sheet is placed on a stage of an opticalmicroscope. The HSV value of each metal sulfide in the image is measured by CCD, and the database of HSV value of metal sulfide is established as the standard of automatic identification of metal sulfide. The metallic sulfide particles are extracted from the samples and their HSV values are measured. According to the HSV value of the mineral particles in the image, the established mineral database is used as a standard to identify the mineral particles, and different minerals are painted with different pseudo-colors to show the difference, thus completing the automatic identification of metalsulphides. The method can effectively solve the problem that the mineral gray level is close to the difficult to distinguish, can accurately and effectively identify the metal sulfide of the rock andmineral samples, and can improve the accuracy of mineral identification.

Description

technical field [0001] The invention relates to an automatic identification of metal sulfides in rock ore samples, in particular to an automatic identification method of optical microscopic images of metal sulfide minerals. Background technique [0002] When conducting rock ore identification and process mineralogy research, it is first necessary to identify and identify minerals in rock ore samples. The commonly used method is for technicians to observe metal sulfides in rock ore samples through an optical microscope, and determine the type of minerals according to their optical characteristics. This way of working requires a high level of technical personnel, and because it is a manual operation, the efficiency is relatively low. [0003] In recent years, in order to improve the work efficiency of the identification and identification of metal sulfides in rock ore samples and reduce the dependence on technicians, the use of digital image analysis technology to automatical...
