Abstract:

Although numerous video-inspecting systems have beenimplemented in different manufacturing domains, in the textile industry there is no video assisting/inspecting of assembling operations in the textile/clothes production flow available on the market. There are some particularities of textile and clothes manufacturing units, severely restricting the customisation of existing video assisting systems to the garment industry. Among these, the most important are the irregularity of lighting caused by the partial obstruction of the optic path (flocks and fluffs interposing between the light source – textile detail – video cam) as well as the presence of fabric undulations which can modify the visible shape of the detail to be identified. In order to overcome these limitations, a novel pattern matching algorithm was developed, named the Learn and Match Mini-Pattern. The working principle of this new algorithm will presume the decimation of a pattern in several partial mini patterns.
