Body-structure-based Cartoon Character Modeling From Multi-view Hand-drawings

Cartoon animation usually refers to the picture style abstract,storyline humorous animation.Cartoon animation with abstract character modeling,exaggerated expression and artistic drawing style,can fully reflect the artist's imagination and painting ability,by the audience at all levels of the wide welcome,and has a broad market.But the traditional animation process usually requires the animator to draw a lot of animation frame,very cumbersome and time-consuming.But the traditional animation process usually requires the animator to draw a lot of animation frames,very cumbersome and time-consuming.Many researchers have explored the new technology of cartoon character animation by referring to the computer character animation process,and put forward many effective solutions to the key problems such as cartoon character modeling,cartoon character movement generation and cartoon style drawing.The geometric modeling of cartoon characters is the basis of cartoon animation creation.The main problem is how to create the geometric model of the role more efficiently and make the model both to maintain the correct geometric features and to express the hand style in cartoon animation.In this paper,a multi-view hand-drawn role modeling method based on human structure is proposed based on human structure and multi-view hand-painted 3D modeling.By scanning the role of multiple viewpoints hand drawing,in each point of view to meet the hand-painted style of the three-dimensional model,thus completing the cartoon role modeling process.Firstly,the two-dimensional skeleton is extracted,the skeleton depth is acquired and the three-dimensional skeleton is generated by the human body structure model.Then,combined with the expansion algorithm and the surface optimization and subdivision algorithm,the local networks matched with the multi-view hand-drawn contour lines are created and combined into the whole network model.Finally,the skeleton subspace deformation is established by using the thermal diffusion algorithm.Thereby a three-dimensional character model is generated.This method can effectively generate three-dimensional network model of human character through the multi-view drawings.At the same time,the process of entering the hand drawing requires no labeling and auxiliary lines.The method is very consistent with the habit of painting master painting.The hand strokes and the geometric features of hand drawing can be consistent.Experiments show that this method can effectively create match the multi-view drawings of cartoon characters model.
