Multi-fuzzy reasoning cascaded primer side defect classification and damage degree analysis method

Abstract

The invention provides a multi-fuzzy reasoning cascaded primer side defect classification and damage degree analysis method. The method comprises the following steps: firstly, acquiring an image I1 from a primer side image I by adopting a threshold method, extracting the area, length, width and gray average value of each connected region in the I1 by adopting a run-length method, and calculating a length-width ratio; secondly, performing expansion operation on the image I1 to obtain a pocking mark weight image I2, and extracting the area of each connected region in the I2 and the number of scatter points in the I1 corresponding to each connected region in the I2; and finally, fuzzifying the extracted data, sending the fuzzified data into a multi-fuzzy reasoning cascade system, sequentially classifying hard spots and non-hard spots, scratches and non-scratches, and heavy oxidation, light oxidation and impurities, and evaluating the damage degree of the hard spots and non-hard spots, scratches and non-scratches, heavy oxidation, light oxidation and impurities. The invention has the advantages that a plurality of fuzzy reasoning classifiers are combined to realize defect classification and damage degree analysis, mutual interference among multiple defects is avoided, the classification precision is improved, and the primer defect false detection condition caused by subjectivity and the like in manual detection is eliminated.

Description

technical field [0001] The invention relates to a primer defect analysis method based on a multi-fuzzy reasoning cascade system, in particular to a primer side defect classification and damage degree analysis method. Background technique [0002] Bullets are an indispensable part of weapons and equipment. Optimizing the production process of weapons and equipment and improving the yield rate will help improve the input-output ratio and ensure the needs of real-time combat. Among them, the primer is the key ignition part at the bottom of the bullet. The primer has the characteristics of long storage time, high ignition stability and safe use. It is widely used in the ignition device at the bottom of various bullets and guns. [0003] The primer is cylindrical as a whole, and the shell material is H68 copper. The inside of the shell is filled with primer, and it is covered and pressed with a paper circle brushed with shellac paint. In the production process of the primer, due...

Problems solved by technology

In the production process of the primer, due to the complex production process and numerous production links, the produced primer inevitably has appearance defects such as gaps, scratches, pitting, impurities, light oxidation, heavy oxidation, and poor size.

[0004] In this case, the traditional method of detecting primer appearance defects by observing the appearance of the primer with the naked eye is easily affected by subjective factors such as human visual fatigue and emotion, which easily leads to a high false detection rate and missed detection rate of the primer. , and the traditional method has low efficiency and low precision
