Abstract

The invention provides a focusing method and device, shooting equipment, a movable platform and a storage medium. The focusing method comprises the steps of determining a first position area corresponding to a target object in a first image collected by first shooting equipment; setting the image sharpness corresponding to the first position area in the first image to have a first weight, and setting the image sharpness corresponding to other areas except the first position area in the first image to have a second weight, the first weight being greater than the second weight; obtaining a definition statistical value of the first image according to the first weight and the second weight; and if the definition statistical value of the first image meets the set focusing condition, focusing the target object to ensure that the target object is imaged clearly.

Description

technical field [0001] The invention relates to the field of cameras, in particular to a focusing method, device, photographing equipment, movable platform and storage medium. Background technique [0002] The camera function is used in many application scenarios, and devices that provide the camera function include mobile phones, cameras, and so on. During the shooting process, in order to ensure a clear imaging picture, a focusing process is necessary. At present, many shooting devices support an auto focus (Auto Focus, AF for short) function, so as to complete focusing through the AF function. [0003] At present, in the process of performing AF, the focus area is often selected to be the center area of ​​the image captured by the shooting device. At this time, the purpose of AF is to ensure that the image in the focus area is clear. With this AF processing method, it is difficult to ensure clear imaging of the target object that the user pays attention to among the seve...
