Abstract
Systems and methods for on-loom detection of faults in fabric. An image-capture trigger-mechanism triggers an imaging device to capture a first image of a section of the weaving area at a first instant during each weft insertion cycle and a second image of the section of weaving area may be captured at a second instant during each weft insertion cycle. The images may be timed to provide images of the warp yarns and the weft yarns at optimal instants during the weft insertion cycle. An image processor detects irregularities in the data received from the imaging device.
Claims20
An on-loom fabric inspection system (500) comprising:
- at least one imaging device (522) configured to collect images of at least one section of a weaving area (518) of a loom (502);
- at least one image-capture trigger-mechanism (529) configured to send trigger signals at multiple instants during each weft insertion cycle;
- and
- at least one image processor (524) configured and operable to receive data from said imaging device (522) and further to detect irregularities in said data;
- wherein said at least one image-capture trigger-mechanism (529) is operable to send trigger signals so as to trigger said imaging device (522) to capture at least:
- a first image of the section of weaving area (518) at a first instant during each weft insertion cycle;
- and
- a second image of the section of weaving area (518) at a second instant during each weft insertion cycle.
A method for detecting defects in a woven fabric comprising:
- configuring at least one imaging device (522) to collect images of at least one section of a weaving area (518) of a loom (502);
- configuring at least one image processor (524) to receive data from said imaging device (522) and further to detect irregularities in said data;
- providing at least one image-capture trigger-mechanism (529);
- the at least one image-capture trigger-mechanism (529) generating a first trigger signal thereby triggering the imaging device (522) to capture a first image of the section of weaving area (518) at a first instant during each weft insertion cycle;
- and
- the at least one image-capture trigger-mechanism (529) generating a second trigger signal thereby triggering the imaging device (522) to capture a second image of the section of weaving area (518) at a second instant during each weft insertion cycle.
