A vision-based yarn scanning system

A new charge coupled device (CCD) linescan camera based yarn data acquisition system for textile yarn characterisation is reported. An interface scheme for the Fairchild CAM 1350 linescan camera to a Motorola M68000 single-board computer, with a parallel data link to an IBM-PC, is described. Yarn analysis software is developed to allow investigation of different yarn characteristics. The results demonstrate applicability as a fast laboratory investigative tool and show further promise for the technique to be extended to full yarn processing speeds allowing on-line monitoring and control of the yarn production processes.
