Abstract
Textile articles are inspected for size, defects by forming an image e.g. in a video camera, capturing data representing at least salient features of the image, comparing the data automatically with reference data, and effecting a selection process in accordance with the result of the comparison. Articles e.g. socks, presented as a succession of imperfectly matched items, can be sorted for size e.g. into categories of leg and foot length.
Claims25
A method for processing textile items having elongate portions defining intersecting bisectors, said items being supplied as a collection of imperfectly matched such items, comprising the steps of
- (a) consistently orienting said items,
- (b) optically capturing data representing at least salient dimensional features of said consistently oriented items as a function of at least the lengths of said bisectors,
- (c) comparing said data automatically with reference data, said reference data including lengths of said bisectors for sets of said items,
- (d) effecting a selection process in accordance with the result of such comparison, and
- (e) segregating said selected items into sets of matched items by said comparison and selection processes.
Apparatus for processing textile items having elongate portions defining intersecting bisectors, said items being supplied as a collection of imperfectly matched such items, comprising in combination:
- (a) means for consistently orienting said items,
- (b) optical data capture means for capturing data representing at least salient dimensional features of said consistently oriented items as a function of at least the lengths of said bisectors,
- (c) comparison means for comparing said captured data automatically with reference data, including lengths of said bisectors for sets of said items,
- (d) selection means adapted to select items from said collection in accordance with the result of said comparison and segregate said selected items into sets of matched items.
