Abstract

The invention discloses a volcanic rock identification method based on the Internet of Things. According to the technical scheme, the volcanic rock identification method is characterized by comprisingthe steps that multiple sets of images of a target object at different collection angles are acquired; carrying out image processing on the plurality of groups of images and then constructing a three-dimensional model of which the surface is composed of a plurality of grid planes; extracting pore distribution information and pore brightness information of the surface layer of the target object according to the multiple groups of images, and performing pore mapping processing on the three-dimensional model according to the pore distribution information; calculating the simulation volume and the pore distribution area of the target object according to the three-dimensional model; calculating a pore average depth value according to the pore brightness information, calculating a pore ratio ofthe surface layer of the target object by taking the depth value as a standard, and calculating the pore ratio of the whole target object in combination with the simulated volume; obtaining the weight value of the target object, and calculating the average density of the solid components according to the weight value and the volume of the solid components; and judging the category of the target object according to the average density distribution range of the entity components to obtain an identification result. And the volcanic rock category can be quickly and accurately identified.

Description

technical field [0001] The present invention relates to the technical field of rock type identification, more specifically, it relates to a method, system, terminal and medium for identifying volcanic rocks based on the Internet of Things. Background technique [0002] Lithology identification is mainly guided by theories of petrology, mineralogy and geochemistry, using technologies such as naked eye observation, microscope observation, and chemical composition analysis of rock samples to identify rocks based on the characteristics of rock color, structure, structure, mineral composition, and content. Conditions, etc. are the process of accurately naming lithology. Lithology identification is one of the main tasks of geological logging work, the basis for the establishment of geological profiles, and the prerequisite work for the study of strata and reservoirs in the process of petroleum exploration and development. [0003] The existing volcanic rock lithology identificati...
