Arbitrary viewpoint image generation method of unknown objects in known environment using a single camera

In this paper, we propose a method to generate arbitrary viewpoint images of unknown objects using a single camera set in a known environment. In recent years, various methods for generating arbitrary viewpoint images have been proposed. These methods often use multiple cameras. When we can generate the arbitrary viewpoint images using only a single camera, we can apply the technique to more various fields. Therefore, we propose the arbitrary viewpoint image generation method by using a single camera and the information of the known environment (size of a room, and the relation between the room and the camera). We set the camera at the rectangular parallelepipeds room and unknown objects on the floor. We generate the arbitrary viewpoint images using the estimated three-dimensional (3D) information of the unknown objects and the known environment information. In the experimental results, we show that the proposed method can estimate the 3D information of the unknown objects and generate the arbitrary viewpoint images.
