Abstract

The invention discloses a rock slice microscopic image automatic labeling method, which is used for improving a manual point tracing and frame drawing link of an image, realizing automatic labeling of a complex rock slice image, classified labeling of different particle types in the same graph, and point tracing and frame drawing of each particle, and endowing a label name corresponding to the particle. According to the method, automatic point tracing and frame drawing of the rock slice image are realized, the labeling time of experts is greatly saved, the experts can be effectively assisted to carry out batch complex rock slice image labeling work, the accuracy is relatively high, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an automatic labeling method for microscopic images of rock thin sections. Background technique [0002] The microscopic image of the rock thin section is an image obtained by grinding a rock sample into a thin slice with a thickness of 0.03 mm, placing it on the stage of a polarizing microscope, and taking it by a thin-section appraisal worker with a high-definition camera. In the field of geology, rock thin section identification is to classify and name minerals by observing and analyzing the composition and content of minerals in rock thin section images. However, usually there are many mineral particles in a rock thin-section image, the contrast between different particles is low, and the internal microstructure of the same particle is complex, which makes the identification of sandstone images more difficult and requires high requirements for identificat...
