Technique for quickly, automatically and precisely recognizing coal rock maceral

Abstract

The invention discloses a technique for quickly, automatically and precisely recognizing a coal rock maceral, and relates to the technical field of metallurgical coking. The technique method comprisesthe steps: firstly continuously capturing microscopic images of all positions which are uniformly distributed on a coal rock light plate, converting each corresponding pixel in each microscopic image, captured by a high-precision camera, of the coal rock light plate, obtaining three basic recognition parameters, segmenting the image into a plurality of recognition regions according to pixels, andsolving the mean value and standard deviation value of all recognition parameters in each region; secondly enabling the regions to be corresponding to the types of real coal rock macerals, carrying out the further trade-off through the three types of limiting parameters, carrying out the gathering and counting, and calculating the total number of effective units, and repeatedly carrying out the above steps; thirdly sequentially calculating all measurement region images which are uniformly distributed on the coal rock macerals, finally carrying out the gathering and counting, and calculating the content of active matters in coal and the content of inert materials in the coal. The beneficial effects of the invention lie in that the technique is high in recognition accuracy of coal rock macerals, is high in speed, and can meet the requirements of many daily to-be-detected samples .

Description

technical field [0001] The invention mainly relates to the technical field of metallurgy and coking, in particular to a technical method for rapid automatic and accurate identification of coal rock microcomponents. Background technique [0002] At present, industries such as geology, coking, and coal washing are all using artificial low-efficiency methods to quantify coal rock microcomponents and detect vitrinite reflectance in coal, which cannot keep up with the speed of production samples. At the same time, there are few measuring points and accurate The accuracy is also limited by the experience of the operator, and the reproducibility of the test results is poor. Therefore, the related industries are in urgent need of an accurate, fast coal and rock testing technology and equipment that can truly meet the production needs. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a rapid, automatic and accura...
