Publication number: 20240386736Abstract: A method of detecting a dot code includes: irradiating the dot code and a background surface by a source of radiation capturing by a reader an image of the dot code and the background surface; distinguishing in the image an edge surface from the background surface based on the difference in spectral reflectivity of the edge surface and the background surface; processing the image of the dot code by dilating in the image the edge surface of the dot, until the centre surface has been closed by the dilating; and reading the processed image to derive the dot code from the processed image. An item includes the dot code having a plural dots arranged on the background surface, where a spectral reflectivity of the edge surface differs from a spectral reflectivity of the background surface.Type: ApplicationFiled: October 24, 2022Publication date: November 21, 2024Inventors: Johannes Bernardus Kerver, Bjørn-Erik Johan Willem Pieter Hendrik van Dommelen
