(EN) SYSTEMS AND METHODS FOR DETERMINING AN ORIENTATION OF AN IMAGE
(FR) SYSTÈMES ET PROCÉDÉS PERMETTANT DE DÉTERMINER UNE ORIENTATION D'UNE IMAGE
Abstract
(EN)
Embodiments for determining an orientation of a scanned image. In an exemplary embodiment, a method comprises receiving image data of an image of one or more objects. Each object of the one or more objects in the image includes a plurality of points on a surface of the object. The method further comprises generating a plurality of subsets of points of the plurality of points and fitting a parametric model to more than one subset of the plurality of subsets to generate a plurality of parametric models. Further, the method identifies a parametric model of the plurality of parametric models that includes the largest number of points and orients the image based on the parametric model that includes the largest number of points.

Modes de réalisation permettant de déterminer une orientation d'une image scannée. Dans un mode de réalisation donné à titre d'exemple, un procédé consiste à recevoir des données d'image d'une image d'un ou de plusieurs objets. Chaque objet du ou des objets dans l'image comprend une pluralité de points sur une surface de l'objet. Le procédé comprend en outre la génération d'une pluralité de sous-ensembles de points de la pluralité de points et l'ajustement d'un modèle paramétrique à plus d'un sous-ensemble de la pluralité de sous-ensembles pour générer une pluralité de modèles paramétriques. En outre, le procédé identifie un modèle paramétrique de la pluralité de modèles paramétriques qui comprend le plus grand nombre de points et oriente l'image sur la base du modèle paramétrique qui comprend le plus grand nombre de points.
