Abstract :
Foreground occlusion is a significant challenge in 3D reconstruction. In the paper, we first characterize the differences between multiview reconstruction with and without foreground occlusion. Considering both scene depth and appearance are unknown, we propose a generalized model for scene reconstruction. Then, we propose an iterative reconstruction approach in the global optimization framework, which is well performed on the camera array system. Even when all views are partially occluded, our approach can recover accurate depth map as well as scene appearance. Experimental results have indicated that our approach is more robust to foreground occlusions and outperforms state-of-the-art approaches.
