Abstract

The invention discloses a focusing method, a camera device and a storage medium, and the method is applied to the camera device, and comprises the steps: obtaining at least two paths of image data collected by the camera device for the same scene in a coarse adjustment process; processing the at least two paths of image data through corresponding evaluation modes to obtain at least two groups of first focusing evaluation operators corresponding to the at least two paths of image data; calculating operator change rates in the at least two groups of first focusing evaluation operators; and in the fine adjustment process, determining the optimal focusing position based on the same-path image data which is subsequently acquired by the camera device and corresponds to the maximum change rate and the corresponding evaluation mode. Through the mode, the operator change rates of different paths of data under the corresponding evaluation modes are obtained through coarse adjustment, the same path of image data corresponding to the maximum change rate in the fine adjustment process and the corresponding evaluation mode are used for determining the optimal focusing position, and the optimal focusing position can be accurately obtained to improve the focusing effect.

Description

technical field [0001] The present application relates to the technical field of imaging, and in particular to a focusing method, an imaging device and a storage medium. Background technique [0002] When taking pictures with a camera device, it is often necessary to focus in different scenes, so as to improve the clarity of the picture taken. With the establishment of a safe city, the camera device in the monitoring system is playing an increasingly important role, which puts forward higher requirements for the focusing effect of the camera device. [0003] At present, due to the diversity of monitoring scenes, clear video images cannot be obtained under certain scenes. For example, in the monitoring scenes of counties, townships, and villages with poor light supplement, the clarity of the pictures captured by the camera device is not good. Therefore, how to improve the focusing effect of the camera device to obtain better camera effects in different scenes is a problem t...
