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.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.
