Abstract

L'invention concerne un procédé, un appareil et un système pour effectuer une occlusion de vidéo. Le procédé consiste en ce que : une plateforme de surveillance reçoit des demandes de vidéo de terminaux de surveillance, et détermine les autorisations des utilisateurs des terminaux de surveillance ; en fonction d'un résultat de la détermination, envoie uniquement des données vidéo non occluses aux terminaux de surveillance des utilisateurs qui ne sont pas autorisés à obtenir des données vidéo occluses ; et envoie des données vidéo occluses et des données vidéo non occluses aux terminaux de surveillance des utilisateurs qui sont autorisés à obtenir une partie ou la totalité des données vidéo occluses de sorte que les données vidéo occluses et les données vidéo non occluses soient reproduites d'une manière combinée, ou envoie des données vidéo qui combinent les données vidéo occluses et les données vidéo non occluses, résolvant un problème de risque pour la sécurité de l'art antérieur provoqué par l'envoi des données d'image d'une partie occluse aux terminaux d'utilisateurs avec différentes autorisations.
