Abstract: Multi-view images captured by a parallel multi-camera array manually placed tend to produce vertical parallax. To eliminate vertical parallax, the multi-view images must be rectified. This paper presents a simple and effective algorithm for multi-view rectification, and builds a stereoscopic display system based on this algorithm. A multithread technique is used to achieve soft synchronization of the cameras, and to perform real-time optimization. When image resolution is 1 280×960, the upload rate is 25 frame/s, and the target 3D display resolution is 1 920×1 080, the display rate of the system can reach 20 frame/s by using the bilinear interpolation. If interpolation methods with low complexity are used, the display rate can reach more than 20 frame/s. A 3DTV system with real-time rectification of eight cameras and stereoscopic display is built by using the proposed algorithm.
