Abstract

The invention discloses a focusing method and device based on face recognition, terminal equipment and a storage medium. The method comprises the following steps: detecting a stable initial face image, and determining a face distance between a target face and a terminal device; inputting the face distance into a pre-established face size model, and determining a target face image size corresponding to the face distance; and determining a focusing position area of the lens based on the target face image size so as to control the lens to move to the focusing position area for focusing. The problem that the focusing speed is low in the face image shooting process is solved.

Description

technical field [0001] The present application generally relates to the technical field of face recognition, and specifically relates to a focusing method, device, terminal device and storage medium based on face recognition. Background technique [0002] In modern life, using a terminal device with a shooting function to take photos has become a common means for people to record and share their lives. [0003] With the popularity of Selfie or portrait photography, in order to meet the needs of users, terminal devices generally support the face focus function. Face focus is based on the face detection area to trigger the focus, and the face is the best clear point. to achieve focus and take pictures. [0004] However, the existing face focusing process usually uses phase focusing (English: Phase Detection Automatic Focus, abbreviated: PDAF), laser focusing (English: Time of Flight, abbreviated: TOF) or contrast focusing (English: Contrast Automatic Focus). , referred to as:...
