Abstract

The invention discloses a focusing method and device, an electronic device and a storage medium. The method comprises the steps of using a ball machine to determine a target identification point closest to the space of a target object according to the second coordinate information of the target object and the third coordinate information of each identification point; pre-storing the corresponding relation between each identification point and the focal length in the ball machine, taking the focal length corresponding to the target identification point as an initial focal length after determining the target identification point, and determining the focal length corresponding to the target object according to the initial focal length and a preset focusing step length. The determined target identification point is closest to the object distance of the target object, so that the target identification point is closest to the focusing focal length of the target object, and the rapid focusing can be realized by focusing on the basis of the initial focal length corresponding to the target object. Compared with a focusing scheme in the prior art, the focusing time is greatly shortened, and the snapshot efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a focusing method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of the security field, the forms of monitoring equipment are becoming more and more diverse. At the same time, combined with artificial intelligence (AI) technology, especially after applications such as face recognition, gun-ball linkage equipment has been widely used. . This type of linkage equipment is generally composed of two parts. The fixed-focus gun is used for global observation. When the target object appears in the screen, it will send the coordinate information of the target object to the zoom dome camera. The zoom dome camera is used to perform coordinate conversion to determine the target object. , and then locate the target object. After the positioning is completed, focus and capture. Therefore, in the process of intellige...
