Abstract: In textile inspection,fabric defects are usually detected by human inspectors.For solving these problems,such as low efficiency,high rate of errors and missing inspections,a new design idea is presented to achieve automatic inspection of the fabric using robustness operation.The major identification methods in fabric inspection and the research achievements in automatic fabric inspection system at home and broad are introduced.The current status and developing trends of software and hardware technology for machine vision are discussed,along with the existent problems in respect to its application to fabric inspection.Finally,it pointed out that developing a distributed robust machine vision detection technology,aiming at high speed product line,is the research and development direction of automatic grey cloth inspection system which is suitable for our country′s situations.
