摘　　要：虚拟现实(Virtual Reality,VR)作为时兴技术之一,为新闻媒体行业增设了形式拓展的可能性。VR技术与国内主流媒体的新闻生产过程不断创新、实践与融合,“VR+新闻”报道模式蓬勃发展。“VR+新闻”模式的实现倚仗于新闻图像的高质量、高传输、高储存技术。目前无现成的、纯熟的VR系统能高水平地实现图像传输,成为阻碍模式发展的一大难题。为此,针对VR超高分辨率新闻图像在线展示关键技术,利用缓存技术、加速技术、新闻图像多分辨率表达技术等,试图解决目前虚拟现实设备上高分辨率新闻图像无法实时快速浏览的问题,深化“VR+新闻”的技术应用。As one of the popular technologies, Virtual Reality(VR) adds the possibility of form expansion to the news media industry.VR technology and the news production process of domestic mainstream media continue to innovate, practice and sew up, so that the “VR+ news” reporting mode is booming. The realization of “VR+ news” mode depends on the high-quality, high transmission, and high storage technology of news images. At present, there is no ready-made and skilled VR system that can realize image transmission at a high level, which has become a major difficulty hindering the progress of the mode. Aiming at the key technologies of VR’s ultra-high resolution news image online display, this paper uses cache technology, acceleration technology, news image multi-resolution expression technology, etc. to try to solve the problem that high-resolution news images cannot be browsed in real-time on virtual reality devices,and deepen the technical application of “VR+ news”.
