摘要
基于未标定图像序列实现任意视点插补 ,是目前视点插补技术研究中的热点 .本文首次将同伦变换引入视点插补问题研究中 ,提出并证明了基于透视同伦变换的视图插补定理 ,并针对可忽略遮挡关系的简单场景给出了基于未标定图像序列的透视同伦变换 .算法实现的关键在于对摄像机内外参数的估计 ,同时对实验结果作了详细分析 ,指出实验结果的优劣 (算法实现瓶颈 )
At present, view interpolation based on uncalibrated images is widely studied. Homotopy transform is first introduced into the view interpolation study, and view interpolation theorem based on perspective homotopy transform is presented. The perspective homotopy transform and its algorithm based on uncalibrated images is presented for non-occlusion scene. The key steps of its implementation are estimate of camera intrinsic and external parameters. The experiment results indicate that the choke point of the algorithm implementation was the problem of finding matched points between the different view images.
