Title
(EN) IMAGING DEVICE
(FR) DISPOSITIF D'IMAGERIE
Abstract
(EN)
Systems and methods are provided for a stable imaging of a camera onboard a UAV. A lens locking apparatus can be provided in the camera to fix the optical lens at a focused position upon completion of focusing the lens on an object, such that the lens does not move or vibrate even when the UAV is in flight. The pressing member (260) can be an elastic plate or a leaf spring which abuts against a lens carrier (210) carrying the optical lens and applies a compressive force to the lens carrier (210). A stable imaging can be obtained since the optical lens is fixed at the focused position, and the captured images may not be blurred due to a loss of focusing.
(FR)
L'invention concerne des systèmes et des procédés de stabilisation des images réalisées par un appareil de prise de vue embarqué sur un UAV. Un appareil de verrouillage d'objectif peut être disposé dans la caméra pour fixer l'objectif optique sur une position de focalisation lors de l'achèvement de la mise au point de l'objectif sur un objet, de telle façon que l'objectif ne se déplace ni ne vibre, même lorsque l'UAV est en vol. L'élément de pression (260) peut être une plaque élastique ou un ressort à lames qui bute contre un support d'objectif (210) portant l'objectif optique et qui applique une force de compression au support d'objectif (210). Il est possible de réaliser des images stables puisque l'objectif optique est fixé sur la position de focalisation, et les images capturées ne peuvent pas devenir floues à cause d'une perte de mise au point.
