Construction of 3D Virtual Humans from 2D Images

Constructing highly realistic virtual human figures and simulating their motions are gaining real application ground in computer games and virtual reality (VR). This paper presents the construction of a 3D virtual human based on three 2D orthogonal images and a standard 3D human model template. The construction methods used are 1) extracting silhouettes of 2D images; 2) comparing discrepancies between the shapes of the template and the individual 2D orthogonal images; 3) deforming triangular mesh model of the template; 4) matching textures and skeleton system. Static and dynamic virtual human models generated via these methods have realistically modeled the shapes and clothes (texture) of 2D body images and simulated body actions based on relevant motion parameters.
