Abstract
A method for training a face detection model, including: acquiring a training face image; performing three-dimensional reconstruction on the training face image based on a preset three-dimensional face model, and acquiring a training three-dimensional face model; generating a training UV coordinate map including three-dimensional coordinates of the training three-dimensional face model based on the training three-dimensional face model; and training a semantic segmentation network by using the training face image and the training UV coordinate map, and acquiring a face detection model. The face detection model is configured to generate a UV coordinate map including three-dimensional coordinates.
