Abstract

The embodiment of the invention discloses a single photo-based 3D human modeling method and device. The method comprises acquiring and analyzing a photo, marking key points of a human body inside thephoto, and computing the space coordinates of the key points; acquiring the distance between bone points of a preset standard human body model and the key points in the photo, and aligning the bone points and the key points to generate a basic human body model; acquiring basic maps of the preset standard human body model, performing deviation calculation on skin textures of human face in the basicmaps and the photo, and performing fusion via edge channels to generate base texture data; according to the basic human body model and the base texture data, generating a 3D human body model. The single photo-based 3D human modeling method can achieve 3D human modeling through one photo; meanwhile, the model comprises bone and muscular system support for producing expressions and motions, and meanwhile, is applicable to secondary editing and high in modeling speed and restoring precision.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and device for modeling a 3D human body based on a single photo. Background technique [0002] 3D human body modeling is one of the most basic research issues in the field of computer graphics and computer vision. Three-dimensional human body models are widely used in identification, medical assistance, film and television production, game production, digital art, etc. [0003] In the prior art, a single photo is used to generate a 3D model, which can only be applied to the level of cartoon entertainment due to the limitation of the reduction effect. . There is also a single photo modeling in the existing technology, which is more realistic in terms of restoration, but the model is not editable, only the key nodes of the photo are restored, and these key grid points are fixed and cannot be generated twice. Editing, displacement cannot be generated, and there i...
