Abstract

The invention discloses a three-dimensional model generation method. The method comprises the following steps: acquiring a target video frame comprising a target object; extracting a two-dimensional coordinate of a key position on the body of the target object from the target video frame; carrying out the matching calculation on the two-dimensional coordinates through a model database, and obtaining the target attitude transformation parameters matched with the two-dimensional coordinates, wherein the model database comprises multiple sets of reference attitude transformation parameters and reference three-dimensional coordinates with the corresponding relation, the reference posture transformation parameter is used for indicating a transformation parameter for transforming the body posture of the reference object from an initial posture to a reference posture, and the reference three-dimensional coordinate is a three-dimensional coordinate of a key position on the body of the reference object under the reference posture; and transforming a reference human body model corresponding to the reference object according to the target posture transformation parameter to obtain a target human body three-dimensional model matched with the target object. According to the invention, the technical effect of improving the fitting degree with the special effect rendering effect when the human body three-dimensional model is applied to the special effect rendering is realized.

Description

technical field [0001] The present disclosure relates to the field of human body models, and in particular to a method and device for generating a three-dimensional model. Background technique [0002] In the related art, for the three-dimensional model of the human body, it is usually only for the head model or for the whole body model. The establishment of the human body model is usually based on the establishment of bone key points. However, the accuracy of the 3D human body model established only for the key points of the bones is relatively low. Especially in video scenes, such as short videos or live broadcasts, when using three-dimensional special effects, due to the inaccurate establishment of the human body model, there will be problems that the special effects do not fit the human body model. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The present disclosure provides a method and device for g...
