Abstract

L'invention concerne un procédé de zoom, un dispositif d'imagerie, un cardan et une plate-forme mobile. Le procédé de zoom est appliqué à un dispositif électronique et consiste à : acquérir une instruction de zoom, l'instruction de zoom comprenant des paramètres de zoom pour ajuster les longueurs focales d'une pluralité de dispositifs d'imagerie ; et selon les paramètres de zoom dans l'instruction de zoom, ajuster les longueurs focales de la pluralité de dispositifs d'imagerie. Les longueurs focales de la pluralité de dispositifs d'imagerie peuvent être ajustées selon les paramètres de zoom dans l'instruction de zoom, ce qui réduit la difficulté de fonctionnement et la vitesse de réaction de zoom de la pluralité de dispositifs d'imagerie, et améliore l'efficacité de travail d'étapes ultérieures.
