FABRIC ALIGNMENT USING A ROBOTIC VISION SYSTEM

Two solid state cameras are used in conjunction with an IBM personal computer and a PUMA 560 robot operating under VAL I to align accurately a fabric deposited on an aluminium work surface. The method adopted and the software used is of a modular design so as to use the end‐effector of the robot to achieve the aligning of the fabric or alternatively to use a dedicated device such as an aligning table. Lighting is by ordinary fluorescent light. The software filters out noise such as the frayed edges of a fabric.
