View Generation for Ftv in Circular Camera Arrangement
نویسندگان
چکیده
There are many researches about the methods to generate free viewpoint image in linear camera arrangement, but it is rare in circular camera arrangement. In this paper, we propose a novel method to generate free viewpoint image for FTV in circular camera arrangement. This method is based on the Ray-Space method, which is one of the Image Based Rendering (IBR) techniques. We can generate arbitrary views by interpolating ray data of the Ray-Space that is constructed by collecting all images of a sequence captured by cameras arranged circularly but not enough in number. Moreover, by analyzing the trajectory of a ray in the Ray-Space, our method can be applied to the case using perspective cameras or the case that the object is not at the center of the circle or it is not small enough compared to the circle.

Fig. 1 shows a Free viewpoint TV (FTV) system [7]. FTV can generate very natural free viewpoint images in real time as shown in Fig. 2. A scene is captured using a dense array of synchronized cameras. The camera images are placed in a simple manner forming a Ray Space [8] that allows rendering the scene from any position by simple processing. So the user can view the scene not only from the ori...

FTV (free-viewpoint television) is an innovative visual media that allows users to view a three-dimensional (3D) scene by freely changing their viewpoints. Thus, it enables realistic viewing and free navigation of 3D scenes. FTV is the ultimate 3DTV with infinite number of views and ranked at the top of visual media. FTV is not a conventional pixel-based system but a ray-based system. New types...

In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity surfaces provides an efficient way to estimate the depth estimation uncertainty which ...

Virtual view synthesis is an essential part of computer vision and 3D applications. A high-quality depth map is the main problem with virtual view synthesis. Because as compared to the color image the resolution of the corresponding depth image is low. In this paper, an efficient and confided method based on the gradual omission of outliers is proposed to compute reliable depth values. In the p...
