Método y sistema para detectar ópticamente y localizar un marcador de dos dimensiones, 2D, en datos de escena 2D, y marcador para el mismo

摘要

A method for optically detecting and localizing a two-dimensional, 2D, marker in 2D scene data, comprises the steps of: a) providing 2D scene data in form of a digital image; b) thresholding the provided image into a binary black and white image while processing it to detect contiguous areas within the image; and c) linearly analyzing said contiguous areas to determine whether they are a marker.
