AI summary

The present disclosure provides a method for generating an animation figure, a device and a storage medium. The method includes: acquiring an image including at least one target object; acquiring position information about key points of the target object in the image; determining target angle information about lines connecting the key points in accordance with the position information about the key points; and adjusting a predetermined animation figure in accordance with the target angle information. A pose of a target animation figure acquired through adjustment is identical to a pose of the target object in the image, and the target animation figure corresponds to the target object.
