Title
(EN) SYSTEM AND METHOD OF GENERATING A VISUAL CODE
(FR) SYSTÈME ET PROCÉDÉ DE GÉNÉRATION D'UN CODE VISUEL
Abstract
(EN)
There is provided a computerized method and system of generating a visual code, the visual code including function patterns and cells, the method comprising: i) obtaining the function patterns and decoded values of the cells; and ii) calculating lightness values for a plurality of the cells based on the decoded values thereof and at least one lighting parameter, the at least one lighting parameter being indicative of a lighting condition under which the visual code is expected to be displayed, giving rise to the visual code adapted to be machine-readable upon being scanned by a scanning device under the lighting condition. There is further provided a computerized method and system of generating a plurality of visual codes in accordance with respective lighting conditions, each visual code of the plurality of visual codes to be superimposed on one or more frames of a video that is expected to be displayed under the respective lighting conditions.
(FR)
L'invention concerne un procédé et un système informatisés permettant de générer un code visuel, le code visuel comprenant des motifs de fonctions et des cellules, ledit procédé consistant à : i) obtenir les motifs de fonctions et les valeurs décodées des cellules; et ii) calculer des valeurs de luminosité pour une pluralité de cellules d'après les valeurs décodées de celles-ci et au moins un paramètre d'éclairage, le ou les paramètres d'éclairage indiquant une condition d'éclairage dans laquelle le code visuel est supposé s'afficher, ce qui permet d'obtenir un code visuel conçu pour être lisible par machine lorsqu'il est balayé par un dispositif de balayage dans la condition d'éclairage. L'invention concerne aussi un procédé et un système informatisés permettant de générer une pluralité de codes visuels conformément aux conditions d'éclairage respectives, chaque code visuel de la pluralité de codes visuels étant superposé sur une ou plusieurs trames d'une vidéo supposée s'afficher dans les conditions d'éclairage respectives.
