Title
(EN) STEREOSCOPIC SYSTEM CALIBRATION AND METHOD
(FR) PROCÉDÉ D'ÉTALONNAGE DE SYSTÈME STÉRÉOSCOPIQUE
Abstract
(EN)
A multi-camera calibration method is provided which includes identifying a plurality of calibration objects in each of a plurality of images, and calculating an error matrix comprising reprojection error values. The reprojection error values comprise a reprojection error for the calibration objects in each of the plurality of images and the error matrix comprises reprojection error values for the image acquisition devices.

L'invention concerne un procédé d'étalonnage multi-caméras qui comprend l'identification d'une pluralité d'objets d'étalonnage dans chacune d'une pluralité d'images, et le calcul d'une matrice d'erreur comprenant des valeurs d'erreur de reprojection. Les valeurs d'erreur de reprojection comprennent une erreur de reprojection pour les objets d'étalonnage dans chacune de la pluralité d'images et la matrice d'erreur comprend des valeurs d'erreur de reprojection pour les dispositifs d'acquisition d'image.
