Abstract
Dans cet article, nous évaluons la pertinence effective du modèle sténopé dans le cadre de la réalité augmentée (RA). Nous mesurons la précision obtenue avec ce modèle en situation réelle, avec des paramètres intrinsèques éventuellement entachés d'erreur. Nous utilisons pour cette étude des images réelles obtenues à partir de caméra de différentes qualités dont les déplacements sont controlés par ordinateur. La scène acquise est consituée d'une mire de calibration et de trois marqueurs placés à différentes distances de la mire. Ce protole nous permet d'utiliser des critères d'évaluation spécifiques à la RA tels que l'erreur d'alignement et l'impression visuelle, en plus de l'erreur de positionnement plus couramment utilisée.

modèle sténopé dans le cadre de la réalité augmentée (RA). Nous mesurons la précision obtenue avec ce modèle en situation réelle, avec des paramètres intrinsèques éventuellement entachés d'erreur. Nous utilisons pour cette étude des images réelles obtenues à partir de caméra de différentes qualités dont les déplacements sont controlés par ordinateur. La scène acquise est consituée d'une mire de calibration et de trois marqueurs placés à différentes distances de la mire. Ce protole nous permet d'utiliser des critères d'évaluation spécifiques à la RA tels que l'erreur d'alignement et l'impression visuelle, en plus de l'erreur de positionnement plus couramment utilisée.</div></front></TEI></record>Pour manipuler ce document sous Unix (Dilib)
