Embodiment

[0052] Example: an IoT-based volcanic rock identification method, such as figure 1 shown, including the following steps:

[0053] Step 1: Acquire multiple sets of images of the target at different acquisition angles.

[0054] Step 2: After performing image processing on multiple sets of images, a 3D model whose surface is composed of multiple mesh planes is constructed. The grid plane is a triangular plane, and the area of ​​the triangular plane is 0.64cm 2 -1.44cm 2 .

[0055] Step 3: Extract the pore distribution information and pore brightness information of the surface layer of the target object according to the multiple sets of images, and perform pore mapping processing on the three-dimensional model according to the pore distribution information.

[0056] Step 4: Calculate the simulated volume and pore distribution area of ​​the target according to the 3D model. For example, the simulated volume and pore distribution area of ​​the target can be automatically calculat...

Abstract

The invention discloses a method for identifying volcanic rocks based on the Internet of Things. The key points of the technical scheme are: acquiring multiple groups of images of different collection angles of the target object; performing image processing on the multiple groups of images to construct a surface composed of multiple grid planes The 3D model of the target object; extract the pore distribution information and pore shade information of the surface layer of the target object according to multiple groups of images, and perform pore mapping processing on the 3D model according to the pore distribution information; calculate the simulated volume and pore distribution area of ​​the target object according to the 3D model ; Calculate the average pore depth value according to the pore lightness information, calculate the pore proportion of the surface layer of the target object based on the depth value, and combine the simulated volume to calculate the overall pore proportion of the target object; obtain the weight value of the target object, according to the weight The average density of the solid component is obtained by calculating the value and the volume of the solid component; the target category is judged according to the distribution range of the average density of the solid component, and the identification result is obtained. It can quickly and accurately identify the types of volcanic rocks.

Description

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