摘要
Abstract
The traditional three?dimensional(3D)character image dynamic reconstruction method based on self?calibration can′t acquire the 3D position of characters motion morphology accurately,and has high deviation of reconstruction results. Ac?cording to the above problems,a 3D character image dynamic reconstruction method based on multimedia technology is put for?ward,in which the monocular image reconstruction algorithm is used to reconstruct the 3D posture of human body. For the recon?struction of monocular human movement image taken by a single camera in multimedia technology,the 2D limbs detection algo?rithm based on component detector is used to detect the 2D limbs of human body according to the tree?shaped model of the hu?man body. The 3D posture reconstruction algorithm based on image coordinate of joint points is used,and the annealing particle filtering algorithm for the prediction of joint point back projection error is adopted to track the 3D posture of human body accor?ding to detection results of human body′s 2D posture,so as to realize the 3D character image dynamic reconstruction. The experi?mental results indicate that the proposed method can realize the dynamic reconstruction of 3D character image accurately,and has high reconstruction accuracy and efficiency.关键词
