一种透视投影下的非刚体迭代重构方法
An Iterative Non-rigid Reconstruction Method under Perspective Projection
摘要
Abstract
Non-rigid three-dimensional reconstruction under perspective projection has both non-rigid deformation and perspective deformation,and it is difficult to distinguish them.Most of the non-rigid three-dimensional reconstruction algorithm is usually simplified,only considering the non-rigid body reconstruction in orthogonal projection.In order to solve the problem of non-rigid body reconstruction in perspective projection,after combination of the EM algorithm based on shape basis and the affine iterative method,a new algorithm for perspective projection is proposed.It uses the advantage of EM algorithm that can solve the problem of data point loss and of affine iterative method that is more accurate and thus can improve the robustness and reconstruction effect.In order to its effectiveness,an iterative reconstruction simulation experiment has been performed by selecting 5 000 consecutive Frank images with facial expressions,which indicates that it has good robustness and reconstruction effect under the perspective projection model,and can accurately reconstruct the non-rigid three-dimensional structure of human face under dynamic scene.关键词
