Abstract
(EN)
The embodiments of the present application relate to a panoramic image generation method, comprising: executing the following steps when acquiring each of a plurality of images: determining a compensation value according to angle information of a light source in the environment; compensating for a photometric value for photometry of the environment according to the compensation value; determining exposure parameters according to the compensated photometric value; acquiring an image according to the exposure parameters; enhancing the details in the image; and generating, after a plurality of images are acquired, a panoramic image according to the plurality of images. According to the embodiments of the present application, images having relatively uniform light intensity at each angle can be obtained for stitching, so as to obtain a panoramic image having a better effect.

Les modes de réalisation de la présente invention concernent un procédé de génération d'image panoramique. Le procédé suppose l'exécution des étapes suivantes lors de l'acquisition de chaque image d'une pluralité d'images : déterminer une valeur de compensation en fonction d'informations sur l'angle d'une source de lumière dans l'environnement ; compenser une valeur photométrique relative à la photométrie de l'environnement en fonction de la valeur de compensation ; déterminer des paramètres d'exposition en fonction de la valeur photométrique compensée ; acquérir une image en fonction des paramètres d'exposition ; améliorer les détails de l'image ; et, après l'acquisition d'une pluralité d'images, générer une image panoramique en fonction de la pluralité d'images. Les modes de réalisation de la présente invention permettent d'obtenir des images ayant une intensité lumineuse relativement uniforme sous chaque angle en vue d'un assemblage et, par conséquent, d'obtenir une image panoramique produisant un meilleur effet.
