Abstract


Nylon filament is the main raw material for textile processing , dyeing uniformity of wire volume is an important indicator of the physical and chemical properties of nylon filament . However existing socks staining grade evaluation method is very backward , inefficient and a higher incidence of miscarriage of justice , but also by the influence of human factors . This not only makes the quality of textile products can not be guaranteed , but also enabling businesses and consumers suffered huge economic losses . Therefore, the development and manufacture efficient high - speed tester with independent intellectual property rights of Textile Engineering an important research topic . Pattern recognition theory , the use of computer vision technology analysis and research on the the socks classification color vision , application providers image theory socks image illumination normalization pretreatment Percentage chromaticity histogram extraction socks image features and the introduction of expert system theory of color vision classification of the socks . On this basis , the completion of the programming work under the Windows platform , and applied to the Guangdong Xinhui Meida Nylon Co., Ltd. chemical fiber textile industry to upgrade technological innovation - Turks ( Tex ) fiber production technology . To sum up, this paper, the major work done : (1) using the quotient image acquired socks image illumination normalization pretreatment ; percentage of color histogram extracted chrominance characteristic parameters as input vector of the expert system to assess the socks dyeing Level the Watao digital processing of the image information , effectively avoiding the influence of the human factor in the subjective assessment . Prepared to achieve the socks color vision grading applications . This program is based on object-oriented program design ideas using Visual C 6.0 programming environment and Matlab computing software together to complete ; realize image acquisition and reading , image preprocessing, feature value extraction and inference engine ; and user-friendly , simple operation, image acquisition and evaluation of the grade can be easily socks . 3 Select the three groups of 1500 socks this hardware and software system performance testing . The test showed that : The system can be highly efficient , rapid Get Watao image information , and the acquired image information quickly and accurately Level Evaluation , the results of error of less than 1.5% , in order to verify the feasibility of the system .
