3D (Three-Dimensional) human body modeling method and device based on multiple pictures

Abstract

The embodiment of the invention discloses a 3D (Three-Dimensional) human body modeling method and device based on multiple pictures. The method comprises the following steps that: obtaining N pieces of pictures, independently identifying the human body key point of each picture, comparing the angle and the distance of a human body in N pieces of pictures to calculate the structure vertexes of theobtained N pieces of pictures, and obtaining the space coordinate of the human body key point; after the space coordinate of a bone point in a pre-established standard human body model is matched withthe space coordinate of the human body key point, generating a basic human body model; after the map textures of N pieces of pictures are obtained, generating a fused map, and carrying out fusion onthe fused map and a basic map in the pre-established standard human body model to generate a basic map; and according to the basic human body model and the basic map, generating a 3D human body model.The model generated by the embodiment of the invention is high in reduction similarity, the obtained human body information is more accurate, the generated texture and structure modeling can be moreaccurate, and modeling speed is high.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a 3D human body modeling method and device based on multiple pictures. 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 existing technology, through the technology of video modeling and multi-angle picture 3D modeling through multiple picture modeling technology, the object is circled or even multiple times around the object through the mobile phone or dual cameras, and the calculation is performed through the contour points in the video , to obtain the spatial coordinates of the relative key points of the object outline to realize 3D modeling. Another is to obtain more information points by taking pi...
