Method and device for acquiring rock strata structure

The invention provides a method and a device for acquiring a rock strata structure. The method comprises the following steps: firstly, receiving scanning images acquired by scanning equipment on each layer of a rock sample under different voltages; based on each preset feature extraction type, performing feature extraction on the scanned image to obtain feature variables of each layer under different voltages; on the basis of each feature extraction type, obtaining feature vectors corresponding to the feature extraction types under different voltages by integrating the feature variables, and the feature vectors corresponding to the feature extraction types comprising the feature variables of all layers under the feature extraction types; and according to the feature vectors corresponding to the feature extraction types under different voltages and a plurality of preset rock categories, determining the rock category of each layer through clustering so as to obtain the lamina structure of the rock sample.
