Textile Quality Control
Textiles produced for use in industrial applications means that the end consumer of the producers product is not the retail industry and that aesthetic defects are generally of no concern during the manufacturing process. However, while aesthetic defects have, by definition, no impact on the structural integrity of the end product, they can give the appearance of ‘low quality’ textile. To give customers a sense of quality about the delivered product, each produced roll of textile is subject to a manual inspection over the complete length of the textile. This is easily multiple kilometers of textile for a single production run.
Preemptively flagging the location and severity of defects that occur during production would relieve the human inspector of having to manually verify every single meter. The focus could then shift to other parts of the production process. The scale of defects can range from 1 cm^2 for the smallest aesthetics defects to significant structural defects spanning several meters of textile.
The solution provided by Robovision allows for the automatic detection of defects and scoring of the quality of the textile per meter. The techniques used allow for real time monitoring of ~2m wide textile using three 12 Megapixel cameras running during the entire length of the production process.
