Document Type and Number:
WIPO Patent Application WO/2024/051756
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a special effect image drawing method and apparatus, a device, and a medium. The method comprises: in response to a special effect drawing request triggered by a user, performing trajectory tracking on a target video provided by the user to obtain a three-dimensional point set corresponding to a motion trajectory of a target object in the target video; performing gridding processing on the three-dimensional point set to obtain a target grid structure; performing mapping processing on the target grid structure to obtain a target special effect image; and displaying in the target video the target special effect image corresponding to the motion trajectory of the target object. According to the technical solution of the present disclosure, a special effect image is generated by means of a three-dimensional point set, so that a three-dimensional special effect image is obtained, thereby improving the display performance of the special effect image.
