Abstract

The embodiment of the invention discloses an image processing method and a related device. The method comprises the steps of obtaining a first real face image; importing the first real face image intoa three-dimensional face model creation engine, and establishing a first three-dimensional face model matched with the face image; adjusting at least one model parameter of the first three-dimensional face model according to a model parameter adjustment strategy, and generating a plurality of two-dimensional virtual face images of the first user and a face feature value of each two-dimensional virtual face image; taking each two-dimensional virtual face image and the corresponding face feature value as sample data, training a preset two-dimensional face model, and obtaining a trained first two-dimensional face model; importing the first real face image into a first two-dimensional face model to obtain a face feature value of the first user; and adding a face feature value of the first user in a preset face feature value template data set of the first user. According to the embodiment of the invention, the data size requirement of the real face photo is reduced, and the image processing efficiency and accuracy are improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to an image processing method and related devices. Background technique [0002] Face recognition technology is a technology that uses computers to analyze face images and extract effective identification information from the pictures for identity verification. In general, face recognition is divided into three steps: positioning, normalization, and comparison. Positioning refers to the recognition and position determination of the face in the image; standardization refers to the adjustment of the original photo to make the face close to the front; face for comparison. In the prior art, face comparison is mainly based on a 2D face model, but when the comparison photos are not frontal or occluded, the 3D face model is better than the 2D face model. When comparing, the 3D face model is easier to distinguish, and it is easier to do face recognition. Howev...
