A single-image large pose three-dimensional color face reconstruction method based on UV position map and CGAN, which uses UV positions to record and generate a three-dimensional point cloud model, then uses a network designed based on CGAN to complete the incomplete face, and finally obtains a complete color three-dimensional face model. By designing an encoder-decoder network, a two-dimensional UV position map that generates and records complete three-dimensional face information from the original RGB image is generated, and then a three-dimensional face is reconstructed from it using a convolutional neural network; then, considering the self-occlusion of large pose faces, a special conditional generative adversarial network is designed to complete the missing UV texture map. The method proposed by the present invention can achieve higher reconstruction accuracy and more texture details. Especially in the application of large pose face image reconstruction, a more complete and realistic three-dimensional face model can be obtained, and it has stronger robustness in dealing with complex environmental factors.
