Embodiment Construction

[0020] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0021] like figure 1 , LED light sources are symmetrically arranged on the left and right sides of the mine car to ensure that the ore is evenly illuminated. At the same time, set up high-definition network industrial cameras and industrial computers. The resolution of the camera is 1920×1080, the optical axis of the lens and the horizontal plane of the ore are 90 。 , and is located directly above the ore, and its field of view covers the detected ore area. The image recognition software is deployed on the industrial computer and connected to the terminal display. The industrial computer and the high-definition network industrial camera are connected in the same local area network.

[0022] The implementation steps are:

[0023] Step 1. Establish a sample library, which contains sample images of ores with different gold ore contents. Humidificatio...

Abstract

The invention discloses a gold ore mineral analysis method based on video analysis for a draw shaft. The method comprises the following steps: 1, establishing a sample library; 2, extracting a gray level co-occurrence matrix from the sample image, wherein the gray level co-occurrence matrix is used for recording image texture features, and establishing and training a neural network according to acorresponding relationship between the gray level co-occurrence matrix and ore classification; 3, acquiring an actual image of the ore to be detected by using a camera, and then extracting a gray level co-occurrence matrix from the actual image; and 4, inputting the gray level co-occurrence matrix obtained in the step 3 into the neural network, obtaining the classification of ores corresponding toeach actual image according to the output value of the neural network, and judging the gold ore content according to the classification of the ores. According to the method, the problems that minerals are very difficult to distinguish manually, the experience of ore detectors is strictly required, the efficiency is low, and the accuracy is low can be quickly solved.

Description

technical field [0001] The invention relates to a method for analyzing gold ore minerals. Background technique [0002] At present, the analysis of gold ore minerals mainly relies on special instruments and manual experience. The former has the problems of poor timeliness and high cost, while the latter has the problems of heavy workload, low efficiency and low accuracy. Contents of the invention [0003] The present invention proposes a method for analyzing gold ore minerals based on video analysis at the chute, the purpose of which is to quickly analyze the gold ore minerals according to video image data, improve efficiency, reduce costs, and increase accuracy. [0004] Technical scheme of the present invention is as follows: [0005] A gold ore mineral analysis method based on video analysis at the shaft, the steps are: [0006] Step 1, set up a sample library, which contains sample images of ores with different gold ore contents; [0007] Step 2, extract the gray sc...
