Single Camera Stereo System Using Prism and Mirrors
نویسندگان
چکیده
Stereo and 3D reconstruction are used by many applications such as object modeling, facial expression studies and human motion analysis. But synchronizing multiple high frame rate cameras require special hardware or sophisticated software solutions. In this paper, we propose a single camera stereo system by using a setup made of prism and mirrors. Our setup is cost effective, portable and can be calibrated similar to two camera stereo to obtain high quality 3D reconstruction. We demonstrate the application of the proposed system in dynamic 3D face expression capture, depth super-resolution in stereo video and general depth estimation.

A Real-Time Catadioptric Stereo System Using Planar Mirrors
By using mirror reflections of a scene, stereo images can be captured with a single camera. Single camera stereo provides both geometric and radiometric advantages over traditional two camera stereo. In this paper, we discuss these advantages and show that the epipolar geometry is restricted to the class of planar motions. In addition we have implemented a real-time system which demonstrates th...

I n this paper, we propose the use of mirrors and a single camera for computational stereo. W h e n compared to conventional stereo systems that use two cameras, our method has a number of significant advantages such as wide field of view, single viewpoint projection, identical camera parameters and ease of calibration. W e propose four stereo systems that use a single camera pointed towards pl...

The omnidirectional vision system has been given increasing attentions in recent years in many engineering research areas such as computer vision and mobile robot since it has wide field of view (FOV). A general method for 360o omnidirectional image acquisition is the catadioptric approach using a coaxially aligned convex mirror and a conventional camera. The catadioptric approach with the conv...

متن کاملSingle-camera panoramic stereo system with single-viewpoint optics.
A simple and successful design for a panoramic stereo system that uses a single camera and multiple mirrors is presented. A wide-baseline stereo enhances the three-dimensional reconstruction accuracy even with a single camera. The feasibility of the system as a practical stereo sensor has been demonstrated with experiments in an indoor environment.
