Abstract

L'invention concerne un ensemble suiveur et cardan. Le suiveur comprend un premier mécanisme d'alimentation, un mécanisme de montage et une partie de fixation, la partie de fixation étant conçue pour être reliée de manière amovible à un cardan portatif, le mécanisme de montage est utilisé pour le montage d'une partie fonctionnelle, et le premier mécanisme d'alimentation fournit une puissance de rotation pour entraîner le mécanisme de montage en rotation. Le suiveur est configuré pour entraîner la partie fonctionnelle en rotation, de sorte que la partie fonctionnelle obtient un meilleur angle, et la partie fonctionnelle peut mieux aider à la photographie, ce qui est propice à la réalisation d'un suivi intelligent par la partie fonctionnelle.
