Abstract

The invention provides an ore classification and particle size grading method and device based on a deep learning network in order to solve the problem that in the prior art, an image recognition technology for analyzing ore categories and particle size distribution at the same time needs to be improved, and belongs to the technical field of ore dressing. According to the method, the improved Faster-RCNN target detection network in computer vision is applied to extract features, classification and positioning of ores are completed at the same time, and an artificially designed feature extractor is replaced; through the ore position extracted by the target detection network, segmenting the ore by using an FCN semantic segmentation network to obtain granularity information of the ore; moreover, the high-quality image information is obtained by carrying out the data preprocessing work of contrast-limited adaptive histogram equalization, white noise removal and the like on the image; and meanwhile, the ore is classified and segmented by combining target detection and semantic segmentation technologies, so that the efficiency of the crusher is improved, the crushing energy consumption is reduced, and guidance is provided for subsequent processes.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to an ore classification, positioning and particle size classification detection method and device based on target detection and semantic segmentation Mask-RCNN deep learning network. Background technique [0002] The type and particle size distribution of the ore is an important basis for evaluating the crushing effect and subsequent processing of the ore. The categories are now mainly divided into magnetite, hematite, limonite and siderite. The particle size parameters mainly include area, perimeter , particle size and volume, etc. The traditional detection method is to use the inefficient, offline manual screening detection method to determine the particle size distribution of the ore after crushing, and experts to manually determine the general category of the ore, which is difficult to meet the needs of beneficiation production. [0003] In recent years,...
