Face three-dimensional reconstruction method based on side face photo

The invention provides a face three-dimensional reconstruction method based on a side face photo. The method mainly comprises the following steps: S1, generating a three-dimensional face shape based on a two-dimensional side face graph by using a face shape recovery network; s2, generating a two-dimensional front face graph based on the two-dimensional side face graph by using a front face generation network; s3, generating a two-dimensional face texture based on the two-dimensional front face image by using a texture generation network; and S4, pasting the two-dimensional face texture obtained in the S3 to the three-dimensional face shape obtained in the S1 through a two-dimensional coordinate UV projection method to obtain a three-dimensional face model. According to the method, the vivid three-dimensional face model can be obtained according to the two-dimensional side face image, and the method has certain innovation and practicability. 本专利提出了一种基于侧脸照片进行人脸三维重建的方法。主要步骤包括：S1：使用人脸形状恢复网络，基于二维侧脸图生成三维人脸形状；S2：使用正
