Human portrait generation method and system, electronic equipment and storage medium

The invention discloses a human portrait generation method and system, electronic equipment and a storage medium. The method comprises the steps of obtaining a user image, a prompt word text and random noise; wherein the number of the user images is one or more; performing face feature extraction processing on the user image to obtain a first feature; performing feature space conversion on the first feature to obtain a second feature; performing word embedding feature query according to the prompt word text to obtain a third feature; performing feature splicing on the second feature and the third feature to obtain a fourth feature; performing text feature coding on the fourth feature to obtain a fifth feature; and according to the fifth feature, performing noise prediction and de-noising processing on the random noise to obtain a human portrait. According to the embodiment of the invention, face feature extraction and feature space conversion are introduced into the image generation step, so that the calculat
