摘要:

新视点合成的目的是从给定图像的不同视点合成新的图像。以前的大多数作品都集中在生成具有固定背景的某些对象的新颖视图。然而,对于某些应用,例如虚拟现实或机器人操作,由于相机的自运动,可能会发生背景的大的变化。如果不考虑环境的结构,则从新颖视图生成的大规模环境的图像可能会失真。在这项工作中,我们提出了一种新的全卷积网络,它可以通过引入逆深度特征来显式地利用结构信息。逆深度特征是从用稀疏标记深度值训练的CNN中获得的。该框架可以很容易地融合来自不同视点的多个图像。为了填充生成图像中缺失的纹理,应用了对抗性损失,这也可以提高整体图像质量。我们的方法进行评估的KITTI数据集。实验结果表明,该方法可以生成大规模场景的新颖视图,且不失真。我们的方法的有效性是通过定性和定量评价证明。

英文摘要:

Novel view synthesis aims to synthesize new images from different viewpoints of given images. Most of previous works focus on generating novel views of certain objects with a fixed background. However, for some applications, such as virtual reality or robotic manipulations, large changes in background may occur due to the egomotion of the camera. Generated images of a large-scale environment from novel views may be distorted if the structure of the environment is not considered. In this work, we propose a novel fully convolutional network, that can take advantage of the structural information explicitly by incorporating the inverse depth features. The inverse depth features are obtained from CNNs trained with sparse labeled depth values. This framework can easily fuse multiple images from different viewpoints. To fill the missing textures in the generated image, adversarial loss is applied, which can also improve the overall image quality. Our method is evaluated on the KITTI dataset. The results show that our method can generate novel views of large-scale scene without distortion. The effectiveness of our approach is demonstrated through qualitative and quantitative evaluation.
