基于雅可比算法的着装人体三维模型重建

The Reconstruction of Wear-human Body’s 3D Model Based on Jacobi Algorithm

根据数字像机拍摄的两幅正面着装人体图像和侧面图像,重建着装人体三维模型的雅可比(Jacobi)算法,在利用平面旋转变换矩阵对基本矩阵进行正交相似变换雅可比方法处理后,计算出特征点三维坐标并组成稀疏的三维网格结构,然后采用分步紧支撑径向基函数进行三维插值逼近运算,重建相应的着装人体三维模型,并根据图像纹理数字化记录技术,将其映射到三维模型上,得到三维着装人体结构渲染效果图·

Jacobi algorithm is put forward to reconstruct wear-human body＇s 3D model through two front wear-human body images and one side image taken with digital camera. After perpendicularity similarity transforming to fundamental matrix through using plain circle transformation matrix, the three dimensions coordinate of the feature point is calculated out and 3D grid construction is made up, through adopting the taut support radial direction foundation function to perform 3D interpolations calculation, relevant wearhuman body＇s 3D model is reconstructed and the exaggerated picture of 3D wear-human body is obtained according to the image grain digitization documentation technology.
