Embodiment Construction

[0037] figure 1 It is a flowchart of the present invention.

[0038] Step 1: Use the flotation on-site image acquisition system to collect the bubble video of zinc flotation and convert the bubble video into continuous images, and perform data preprocessing on the collected zinc flotation image data, as follows:

[0039] 1) Eliminate erroneous data that exceeds the normal change threshold;

[0040] 2) Eliminate incomplete data;

[0041] Step 2: Convert the bubble image from an RGB color image to a grayscale image, and obtain the grayscale matrix A of the image:

[0042]

[0043] e gf Represents the gray value corresponding to each pixel in the gray image, where g∈N, f∈N, N∈(400,800);

[0044] Step 3: In the bubble image, the normal shape of the bubble is a smooth surface. The highlighted point is located on the top of the convex surface of a single bubble. The highlighted point area presents the minimum gray value, and the highlighted point is the center, and the gray v...

Abstract

A texture roughness definition method based on Euclidean distance determination. In the field of froth flotation, a new texture feature measurement method based on Euclidean distance is proposed. This method extracts foam images based on the digital image acquisition system set up on site. The concept of area, and use the method of Euclidean distance judgment to accurately extract the particle area on the surface of the bubble, and perform a series of measurements on the extracted particle area, and define the grain roughness of the texture feature, which is used to reflect the entire image. texture features. This method effectively makes up for the defect that the traditional texture feature extraction method does not consider the foam surface particles, so that it can judge the working conditions more accurately and effectively guide the dosing.

Description

technical field [0001] The invention belongs to the technical field of froth flotation, and in particular relates to a texture feature measurement method in the zinc flotation process. Background technique [0002] Froth flotation is a mineral processing method widely used at home and abroad. This method can effectively separate the target minerals according to the difference between the hydrophilicity and hydrophobicity of the mineral surface. In the process of froth flotation, the target mineral and its symbiotic gangue are ground into particles of suitable size and then sent to the flotation tank. The surface properties of different mineral particles are adjusted by adding reagents, while the flotation process is continuously stirred and blown to make the slurry A large number of bubbles with different sizes, shapes, textures and other characteristic information are formed in the flotation cell, so that useful mineral particles adhere to the surface of the bubbles, and th...
