Method for automatically detecting defect in electronic representation of endless textile web, involves comparing test equivalence representation with reference equivalence representation, and determining variation of comparison

摘要

The method involves determining dimension (14) of an analysis section (3) from a defective electronic representation (2) in a training phase (1). The representation is overlapped with the section, and a reference equivalence representation (6) of an overlapping region is determined. Representation of an object (8) to be tested is overlapped with the section in a test phase (7), and a test equivalence representation (9) of the overlapping region is determined. The test equivalence representation is compared with the reference representation, and variation of the comparison is determined.
