A VISION-BASED YARN SCANNING SYSTEM

A new charge coupled device (CCD) linescan camera based yarn data acqu isition system for textile yarn characterisation is reported. An inter face scheme for the Fairchild CAM 1350 linescan camera to a Motorola M 68000 single-board computer, with a parallel data link to an IBM-PC, i s described. Yarn analysis software is developed to allow investigatio n of different yarn characteristics. The results demonstrate applicabi lity as a fast laboratory investigative tool and show further promise for the technique to be extended to full yarn processing speeds allowi ng on-line monitoring and control of the yarn production processes.
