Abstract: Provided are a virtual digital human generation method and apparatus, and an electronic device. The method includes: acquiring a first image frame collected by an image collection apparatus when a target video is played; performing human body key identification on the first image frame, to determine position information between human body key points, a first actual length of a target body part, and a second actual length of a body part other than the target body part; on the basis of a target proportional relationship and the first actual length, determining a predicted length of the body part other than the target body part; on the basis of the second actual length and the predicted length, determining a drawing height of the other body part; and performing drawing on the basis of the first actual length, the drawing height and position information, to generate a virtual digital human.
