Abstract

The present application relates to a focusing method and device, electronic equipment, and a computer-readable storage medium. The method includes: acquiring a first preview image; inputting the first preview image into a subject detection model to obtain a target subject area in the first preview image, wherein the subject detection model is based on the visible light map of the same scene in advance, the center weight The model obtained by training the image and the corresponding marked subject, or the subject detection model is a model obtained by pre-training the visible light map, center weight map, depth map and the corresponding marked subject of the same scene; when the target is detected When the subject area contains light spots, the target subject area is processed to obtain the area without light spots in the target subject area; the area without light spots is used as the focus area of ​​the first preview image for automatic focusing, which can avoid light spots when focusing interference, thereby improving the accuracy of focusing.

Description

Technical field[0001]The present application relates to an image field, in particular to a focus method and apparatus, an electronic device, a computer readable storage medium.Background technique[0002]When shooting with a camera, the focus is generally combined with ROI (Region of Interest, INTEREST). Since the ROI range is relatively fixed, when interference occurs, for example, a spot occurs, it will affect the accuracy of the camera focus.Inventive content[0003]The present application provides a focus method, apparatus, electronic device, computer readable storage medium, which can improve the accuracy of the camera focus.[0004]A focus method, including:[0005]Get the first preview image;[0006]The first preview image is input to the main detection model to obtain a target main body region in the first preview image, wherein the main body detection model is a visible light pattern in advance according to the same scene, the central weight map and the corresponding The model of the...
