Abstract

La présente invention a pour objet un support de calibration d'une caméra embarquée dans un véhicule automobile, ledit support de calibration (10) comprenant un réseau de repères de calibration (14) disposés consécutivement en au moins une ligne (12) et/ou au moins une colonne (13), chaque repère de calibration (14) se présentant sous la forme d'une figure géométrique plane divisée en une pluralité de portions (14a) se rejoignant en un point de calibration (15), le support de calibration (10) étant remarquable en ce que les points de calibration (15) d'au moins deux repères de calibration (14) d'une même ligne (12) ou d'une même colonne (13) soient désalignés respectivement horizontalement ou verticalement.The subject of the present invention is a calibration support for a camera on board a motor vehicle, said calibration support (10) comprising a network of calibration marks (14) arranged consecutively in at least one line (12) and / or at least one column (13), each calibration mark (14) being in the form of a plane geometric figure divided into a plurality of portions (14a) meeting at a calibration point (15), the calibration support (10) being remarkable in that the calibration points (15) of at least two calibration marks (14) of the same line (12) or of the same column (13) are respectively misaligned horizontally or vertically.
