Novel view synthesis is a challenging problem in 3D vision and robotics. Different from the existing works, which need the reference images or 3D model, we propose a novel paradigm to this problem. That is, we synthesize the novel view from a 6-DoF pose directly. Although this setting is the most straightforward way, there are few works addressing it. While, our experiments demonstrate that, with a concise CNN, we could get a meaningful parametric model which could reconstruct the correct scenery images only from the 6-DoF pose. To this end, we propose a two-stage learning strategy, which consists of two consecutive CNNs: GenNet and RefineNet. The GenNet generates a coarse image from a camera pose. The RefineNet is a generative adversarial network that could refine the coarse image. In this way, we decouple the geometric relationship mapping and texture detail rendering. Extensive experiments conducted on the public datasets prove the effectiveness of our method. We believe this paradigm is of high research and application value and could be an important direction in novel view synthesis. We will share our code after the acceptance of this work.
