Abstract

The invention relates to a target focus tracking method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: receiving a photographing instruction, and controlling a camera to collect a plurality of frames of images according to the photographing instruction; obtaining a current preview image, and performing target main body segmentation on the current preview image to obtain a target main body mask image; determining an external area of the target main body mask pattern according to the area parameters of the target main body mask pattern; and generating a focus tracking prediction frame of the current preview image according to the target main body mask image and the external area, and performing focus tracking processing on a nextframe of image by using the focus tracking prediction frame. By adopting the method, focus tracking processing can be carried out on the target main body according to the focus tracking prediction frame of each frame of image, so that continuous focus tracking can be accurately carried out on the target main body, and the focus tracking accuracy is effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for tracking a target, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of photographic technology, photographic technology is widely used in various electronic devices. The user can shoot through the electronic device, and can focus on the shooting object when shooting. At present, some focus tracking methods based on visual target tracking such as optical flow tracking and signal prediction tracking have appeared. In scenes where the main target is moving, blocked, and the lighting changes greatly, it is easy to fail to focus, requiring the user to manually focus frequently, and the focus tracking efficiency of the main target is low, which may easily lead to focus failure. Contents of the invention [0003] Embodiments of the present application provide a target focus tracking m...
