摘要

随着虚拟现实(virtual reality, VR)技术的发展, 3D-VR视频已成为技术与商业热点. 3D-VR多机拍摄会导致部分画面出现色彩差异, 影响观众的观影体验. 定量分析视频中左右视差图亮度、饱和度、色相差异对观众舒适度的影响. 通过主观评价实验, 基于HSL (色相(hue)、饱和度(saturation)、亮度(lightness))颜色空间建立了3D-VR视频纹理差异与舒适度关系模型. 根据舒适度评价模型设计了舒适度预警平台, 为3D-VR影视内容创作和制作提供服务.

Abstract

With development of the virtual reality (VR) technology, 3D-VR video has become a hot spot. 3D-VR video is taken with multiple cameras, which would lead to color differences in some parts of the screen. The differences in hue, saturation and lightness of the left-right parallax that affecting audience comfort are quantitatively analyzed. In a subjective evaluation experiment, a relationship model between 3D-VR texture difference and comfort is built based on HSL (hue, saturation, lightness) color space. With the model, a visualization early warning platform of VR video texture is development to help artists in the 3D-VR content production and creation.

Key words： HSL (hue, saturation and lightness) model; human visual system; visual comfort; 3D-virtual reality (VR)
