Abstract
An automated vision inspection system detects whether a cushion of a side curtain airbag assembly system is twisted. The cushion is provided a plurality of markings arrayed along a longitudinal extent of the cushion. Each marking can be defined by a group of four distinct characters or indicia. Each indicium can be defined by polygonal shaped pixels which allow the inspection system to find clear edges of the marking and thereby determine marking orientation. By determining orientation, the inspection system can compare the inspected marking to a master image of the marking to determine if the cushion is in a twisted state or non-twisted state.
