More Information
Summary:The invention discloses a face focusing method and device and electronic equipment, and belongs to the technical field of camera shooting. The face focusing method provided by the invention comprises the following steps: inputting a target image into a target parameter detection model to obtain a target focal length output by the target parameter detection model; focusing the face based on the target focal length; wherein the target parameter detection model is obtained by training based on a two-dimensional face image sample in combination with a three-dimensional face deformation model and a camera model; the three-dimensional face deformation model is used for obtaining a three-dimensional face based on input face feature parameters; the camera model is used for obtaining a restored two-dimensional face image based on the input pose parameters and the three-dimensional face; wherein the face feature parameters and the pose parameters are parameters output by the initial parameter detection model based on t
