Abstract


3D modeling of the human body means that the establishment of a realistic 3D human body model based on the body data obtained.There are two main research directions to establishment the 3D modeling of the human body: The first method is that using a variety methods to data collection and then establish the 3D human body model fully by process these data. The second method is 3D reconstruction of the human body.That is according to the data obtained reconstruction the standard 3D human body model to get a realistic 3D human body model. In contrast, the first method of modeling possess high accuracy, but it is costly on the same time. How to to obtain high precision 3D human body model on the low-cost has become one of the hot nowadays.3D reconstruction of human body based on multiple images, with 3D reconstruction of human thought based on the feature points , extract the human body data in the image, reconstruct the standard human body model. If you rely on the 3D modeling of human body method based on feature points, the result of the method only can get a 3D human body model with the similar broad with the image. On the shortcomings of the reconstruction of 3D human body model method based on feature points, first of all adjust the human body model through the feature points 3D human body model reconstruction, then divided the results into head, neck, trunk, arm, hand, leg, feet and so on. Preprocessing the image to extract image contours and deviding the contour into head, neck, trunk, arms, hands, legs, feet a few parts, plus parts of signs to coordinate the storage structure of data stored contour points. All parts of the 3D human model correspond to the parts come from the image toget the final 3D human body model by sub-parts layer by layer reconstruction. Finally, devide the final 3D human body model into various parts, corresponding to the the corresponding parts in the picture, extract real texture information and loaded into 3D human body model to get the 3D human body model possess thereal texture and high similarity with the real human body outline.The results shows: Based on the reconstruction of feature points to do sub-parts layer by layer reconstruction, the reconstructed 3D human body model possess higher modeling accuracy in ensuring low-cost, high efficiency.
