Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0065]The invention relates to an automatic optical identification method of ore. Aspects of the invention include segmenting ore photographs to distinguish background regions from ore regions and obtaining ore features of the ore regions and performing ore identification based on the ore features. Before segmenting the ore photo, the ore photo can be preprocessed, and then the preprocessed ore photo can be divided into a background area and an ore area by using Euclidean distance transformation. For the ore area obtained by segmentation, multiple ore features and positions of the ore area may be ...

Abstract

The invention discloses an automatic optical ore identification method which comprises the following steps: S1: dividing an ore photo to distinguish a background area from an ore area; S2: obtaining ore characteristics of the ore area and performing ore identification based on the ore characteristics. Before the ore photo is divided, the ore photo is subjected to pretreatment, then the pretreatedore photo is divided into the background area and the ore area through Euclidean distance transformation. A plurality of ore characteristics and positions of the ore area can be extracted from the divided ore area. Ore identification is carried out based on the ore characteristics by use of a BP neural network, and the position of the ore area identified as ore is output. By implementing the automatic optical ore identification method disclosed by the invention and adopting a computer readable storage medium, a processor is employed to perform automatic optical ore identification; thus, compared with manual selection, the automatic optical ore identification method has the advantages of high speed, high production efficiency, low cost and high separation rate.

Description

technical field [0001] The invention relates to the field of ore identification, in particular to an automatic optical identification method for ore. Background technique [0002] Tungsten is a rare metal with high melting point or refractory rare metal in the field of metallurgy and metal materials. Tungsten and its alloys are one of the most important functional materials in modern industry, national defense and high-tech applications, and are widely used in aerospace, atomic energy, shipbuilding, automobile industry, electrical industry, electronics industry, chemical industry and many other fields. In the prior art, the tungsten ore is usually identified and sorted by hand, so there are defects of low production efficiency, high cost, high labor intensity and low sorting rate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic optical identification method for ore, which uses a processor to perform...
