The present invention provides methods and apparatuses for face orientation estimation and network training, and an electronic device and a storage medium. The method comprises: obtaining a face image to be detected; using a face orientation estimation network to process said face image, and determining a face orientation of said face image, wherein a position map is provided in a hidden layer of the face orientation estimation network, the face orientation estimation network is a network obtained by supervising and training a sample face image according to the position map, and the position map is two-dimensional representation of the complete three-dimensional face shape of the sample face image in a three-dimensional modeling space; and outputting the face orientation of said face image. The present invention solves the problem in the prior art that the face orientation estimation error is large, and the effect of obtaining a more accurate face orientation recognition result is achieved.
