Title (EN) QR CODE POSITIONING METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE POSITIONNEMENT DE CODE QR
(ZH) 二维码定位方法及装置
Abstract:
(EN) A QR code positioning method and apparatus. The method comprises: first determining, according to a sequential arrangement ratio of a first-type pixel, a second-type pixel, and a first-type pixel, center positions of suspected position patterns in a QR code image containing the first-type pixels and the second-type pixels; then identifying corresponding suspected position detection patterns according to the determined center positions of the suspected position detection patterns; and determining a pattern conforming to a QR code positioning rule from the identified suspected position detection patterns and using the determined pattern as a position detection pattern of the QR code.
(FR) La présente invention concerne un procédé et un appareil de positionnement de code QR. Le procédé comprend : d'abord, la détermination, selon un rapport d'agencement séquentiel d'un pixel de premier type, d'un pixel de second type et d'un pixel de premier type, de positions centrales de motifs de position suspectés dans une image de code QR contenant les pixels de premier type et les pixels de second type; ensuite l'identification, correspondant aux motifs de détection de position suspectés selon les positions centrales déterminées, des motifs de détection de position suspectés; et la détermination d'un motif conforme à une règle de positionnement de code QR à partir des motifs de détection de position suspectés identifiés et l'utilisation des motifs déterminés en tant que motif de détection de position du code QR.
(ZH) 一种二维码定位方法及装置,其中方法为:首先根据第一类像素、第二类像素、第一类像素的顺序排布比例从含有第一类像素和第二类像素的二维码图像中确定二维码图像中的疑似位置图形的中心位置;之后,根据确定的疑似位置探测图形的中心位置识别出相应的疑似位置探测图形;然后,从识别出的疑似位置探测图形中,确定出符合二维码定位规则的图形,将确定出的图形作为二维码图像的位置探测图形。
