| Popis: | Stereoscopic images are captured by two cameras at different positions. In general, the two images often have geometric distortions including vertical misalignment, rotation and keystone as well as photometric distortions such as luminance or color differences. Even in case of a carefully designed parallel stereo camera configuration, the captured images pairs may have the distortions that cause uncomfortable 3D experiences to users. In this paper, we develop an algorithm to correct the captured image pairs to give a comfortable stereoscopic experience to users. The algorithm provides a practical method for compensating the photometric and geometrical distortions. |
