Cell-based 3D Video Capture of a Freely-moving Object Using Multi-viewpoint Active Cameras
نویسندگان
چکیده
We propose a method to capture 3D video of an object that moves in a large area using active cameras. Our main ideas are to partition a desired target area into hexagonal cells, and to control active cameras based on these cells. Accurate camera calibration and continuous capture of the object with at least one third of the cameras are guaranteed regardless of the object’s motion. We show advantages of our method over an existing capture method using fixed cameras. We also show that our method can be applied to a real studio.

New Viewpoint Video Synthesis in Natural Scene Using Uncalibrated Multiple Moving Cameras
In most conventional systems for new viewpoint video synthesis of a moving object, calibrated multiple fixed cameras are used. Field of view of every camera must cover all the area in which the object moves. If the area is large, object size in the captured images and also in the new viewpoint video will become very small. In this paper, we propose a novel method to synthesize new viewpoint vid...
متن کاملFree Viewpoint Video Synthesis based on Natural Features Using Uncalibrated Moving Cameras
In most of previous systems for free viewpoint video synthesis of a moving object, cameras are calibrated once at initial setting and can not zoom or change view direction during capture. Field of view of each camera in those systems must cover all the area in which the object moves. If the area is large, the object’s resolution in the captured video and also in the free viewpoint video will be...
متن کاملFree Viewpoint Image Synthesis Using Uncalibrated Multiple Moving Cameras
We propose a novel method to synthesize free-viewpoint images for a moving object, which is captured by uncalibrated multiple moving cameras. If multiple fixed cameras are used for capturing a moving object, we must zoom out in order to capture the moving object within FOV of the cameras. Such zooming-out limits the resolution for the moving object in the captured images. In the proposed method...
متن کاملModel-based Free-viewpoint Video: Acquisition, Rendering, and Encoding
In recent years, the convergence of computer vision and computer graphics has put forth free-viewpoint video as a new field of research. The goal is to advance traditional 2D video into an immersive medium that enables the viewer to interactively choose an arbitrary viewpoint in 3D space onto the a scene while it plays back. In this paper we give an overview of a system for reconstructing, rend...
متن کاملMonocular Stereo Measurement Using High-Speed Catadioptric Tracking
This paper presents a novel concept of real-time catadioptric stereo tracking using a single ultrafast mirror-drive pan-tilt active vision system that can simultaneously switch between hundreds of different views in a second. By accelerating video-shooting, computation, and actuation at the millisecond-granularity level for time-division multithreaded processing in ultrafast gaze control, the a...
