The invention discloses a digital rock core identification method based on image processing, comprising: taking first image data; splicing the first image to form second image data; outputting the third image from the first rock core layering model; The layer model outputs the fourth image; the particle analysis and weathering degree analysis of each rock layer are performed on the fourth image, and the core classification data is generated according to the analysis results, core fracture data and core layering data. The invention also discloses a digital rock core identification system based on image processing. The digital rock core identification method and system based on image processing of the present invention can form core stratification and fracture-related data by taking pictures of the core box and image processing, and can quickly analyze the rock core through particle analysis and weathering degree analysis. Classifying the core improves the efficiency of core analysis and is very beneficial for on-site use.
Description
technical field [0001] The invention relates to a rock core identification technology, in particular to a digital rock core identification method and system based on image processing. Background technique [0002] Core analysis in engineering geology usually requires cumbersome manual measurement, weighing and experience to complete, which is not only a lot of work but also inefficient. In the actual exploration and collection of a large number of geological samples, the completion of sample identification and classification needs to go through a long period. At the same time, the empirical factors in the analysis process also limit the analysis of samples. [0003] In the prior art, some identification of rock cores has been realized through image recognition technology, chromatographic analysis technology and CT technology, but the equipment using these technologies is complex and bulky, and there is basically no possibility of portability. However, at the drilling site ...
