Rock slice intelligent identification device and method

Abstract

The invention discloses an intelligent identification device and method for a rock slice, and the device comprises microscopic image collection equipment which collects a rock microscopic image of the rock slice; mineral measurement imaging equipment which is used for acquiring a mineral fingerprint image of the rock slice; and an image processing system which is connected with the microscopic image acquisition equipment and the mineral measurement imaging equipment, and is used for identifying the rock slice based on the rock microscopic image and the mineral fingerprint image. According to the intelligent identification device for the rock slice, the method comprises the steps: acquiring the rock microscopic image through the microscopic image acquisition equipment, acquiring the mineral fingerprint image through the mineral measurement imaging equipment, digitally synthesizing the rock microscopic image and the mineral fingerprint image through the image processing system, and identifying the rock slice; and finally, outputting a rock slice identification report, so that intelligent and automatic identification of the rock slice is realized, the influence of subjective factors of manual identification is avoided, the identification accuracy is high, and the identification speed is high.

Description

technical field [0001] The invention belongs to the fields of geology, petroleum geology and rock and mine experiment research, and in particular relates to an intelligent identification device and method for rock thin section samples. Background technique [0002] Rock (mineral) identification is the precursor and foundation of all research in the geological and energy mineral industries. Since 1827, the Scottish geologist William Nickell invented the polarizing microscope and the thin-section method, and the British geologist Clifton Soapy applied it to rock research, grinding the rock into a thin slice with a thickness of 30 μ, Observing the optical properties of minerals with transmitted light under a polarizing microscope and accurately identifying them has become a basic means of rock (mineral) identification. In the past 200 years, with the continuous advancement of science and technology, although various new testing techniques and research methods have been continu...
