Abstract


With the rapid expansion of the high-speed development of science and technology as well as the amount of information in large-scale scientific visualization, computer supported telemedicine, military simulation, engineering design, remote sensing, convention and exhibition industry and digital cinema, and many people on the video quality and display technologies have become increasingly demanding, the main demand for video quality performance for high resolution and a wide viewing angle, the main demand of the display performance for large display size and a strong sense of immersion. Combined image stitching technology and multi-projection display technology to build high-quality panoramic video generated with immersive display system based on multi-camera, able to meet people at the same time high-resolution, wide viewing angle, high-quality video and immersive display requirements. This paper focuses on high-quality panoramic video generation immersive display technology, a complete system based on the more general camera real-time generation of high-quality panoramic video with immersive display. By camera calibration, adjustment and optimization homography between the camera (Homography) to reduce image mosaic of geometric errors; take full advantage of video streaming technology to achieve multi-channel synchronous real-time transmission of video; comprehensive utilization of multi-core CPU and graphics card computing power for real-time image fusion results of image alignment, to achieve real-time generation of high-quality panoramic video. High-resolution, wide viewing angle panoramic video through multi projector seamless display system to achieve immersive display. The research of this paper include: (1) the development of tools to adjust the picture homography (Homography). The tool can be adjusted, the geometric relationship between the picture optimized to effectively reduce the parallax caused by the shooting camera optical center does not coincide; adjusted with cluster (bundle adjustment) at the same time of splicing parameters further global optimization, to achieve high-quality panoramic image stitching . (2) In order to ensure the system's real-time video streaming technology to achieve full use of the multi-channel synchronous real-time transmission of video, and comprehensive utilization of the computing power of multi-core CPU and graphics card for multi-channel synchronous video stitching, real-time generation of high-quality panoramic video. (3) multi-projector seamless display system used in high-quality panoramic video display to the user a strong impact and immersion. This work relates to the field of computer vision, computer graphics, video transmission, high-performance computing and graphics acceleration. System integration of image stitching technology, seamless video streaming technology as well as multi-projector display technology, to achieve real-time generation of high-quality panoramic video with immersive display.
