METHOD AND APPARATUS FOR GENERATING 3D HAND MODEL, AND ELECTRONIC DEVICE

Disclosed in the embodiments of the present application are a method and apparatus for generating a 3D hand model, and an electronic device. The method comprises: acquiring a hand motion video which is obtained by means of performing image collection during the process of a target user rotating his/her wrist joint from a first angle to a second angle while maintaining a hand posture of his/her five fingers being naturally spread, such that the hand motion video comprises a plurality of frames of image content, which are collected during a rotation process of the hand rotating from front view/side view to side view/front view; acquiring curvature information of the fingers and/or nails from among the plurality of frames of image content, which are collected during the rotation process; and creating a 3D hand model of the target user according to the hand motion video, and optimizing key point parameters of finger parts and/or nail parts in the 3D hand model according to the curvature information of the fingers
