Title:
FOCUSING METHOD AND ASSEMBLY FOR IMAGING APPARATUS, IMAGING APPARATUS AND MOVABLE OBJECT
Document Type and Number:
WIPO Patent Application WO/2021/035704
Kind Code:
A1
Abstract:
A focusing method for an imaging apparatus, a focusing assembly (500) for an imaging apparatus, an imaging apparatus, a movable object and a computer-readable storage medium. The focusing method for the imaging apparatus comprises: (S102) acquiring an object distance of an imaging object; (S104) determining the focusing position of a focusing electric motor according to the object distance; and (S106) controlling the focusing electric motor to move to the focusing position, wherein the focusing position corresponds to the object distance of the imaging object. Since the focusing electric motor no longer needs to move to all positions and perform contrast comparison on each frame of image, the focusing speed of the imaging apparatus is improved.
