Abstract
A method and apparatus measure lengths on an article such as a garment by arranging the article in a field of view of an imaging device, e.g. a video camera forming a pixel image in an x-y array, identifying measurement points on the pixel image in terms of x and y coordinates of the array and evaluating actual lengths between identified measurement points by carrying out for example in a computer appropriate Pythagorean calculations based on the the coordinates and modified to correct for scale and system distortions. Measurement points can be identified by marking the article. The method and apparatus are of use for example in the measurement of shrinkage.
