Abstract

Une caméra à large champ de vision et à billiards de pixels, celle-ci comprenant : un mécanisme de corps principal et un module de caméra (300), le module de caméra (300) étant monté de manière amovible à l'intérieur du mécanisme de corps principal. Le module de caméra (300) comprend de multiples modules de lentille et un cadre de montage, les multiples modules de lentille étant tous montés de manière amovible sur le cadre de montage, les multiples modules de lentille ayant des angles de photographie fixes dans une direction verticale et permettant de photographier à différents angles dans une direction horizontale, les angles de champ de vision de deux modules de lentille adjacents comportant des zones qui se chevauchent partiellement, et les longueurs focales des multiples modules de lentille étant les mêmes. Un module de lentille comprend une lentille (303) et un module (304). De multiples lentilles (303) sont fournies, les images vidéo photographiées par chaque lentille (303) sont fixes dans la direction verticale et sont photographiées à différents angles dans la direction horizontale, et les images photographiées par les lentilles (303) comportent certaines zones de chevauchement de façon à garantir qu'il y a suffisamment de caractéristiques entre des images de lentilles (303) adjacentes pour permettre de les combiner et de les fusionner, de telle sorte que l'angle de champ de vision de la caméra peut atteindre de 180° à 360°. Ceci permet à la caméra de présenter une faible déformation d'image tout en ayant un champ de vision plus grand, ce qui permet d'augmenter la résolution.
