立体显示下的双目颜色融合研究现状与展望

Research Status and Prospect of Binocular Color Fusion in Stereoscopic Displays

立体显示是未来显示技术发展的重要方向,而左右眼视图颜色不一致是立体显示中常见的现象,会导致人眼观看时视觉不舒适。在立体显示条件下,不一致颜色的双目融合研究是传统颜色视觉研究的扩展和补充,不仅对了解人眼视觉系统视信息处理过程及机理有一定的科学意义,而且对解决现有立体显示技术视觉不舒适难题也有应用价值。本文对人眼双目颜色融合的相关研究文献进行了整理,从双目颜色融合、颜色融合与立体融合的交互作用及双目颜色融合对立体显示视觉舒适度的影响三个方面展开分析,总结了双目颜色融合的研究现状,指出目前对视觉系统的双目颜色融合与立体融合的交互机制仍然不完全清楚,研究结果多停留在现象描述上,缺乏定量的实验数据来建立双目颜色融合模型。并提出双目颜色不一致会影响立体显示视觉舒适度,而基于立体显示技术的图像增强方法将成为未来的研究热点。

Three-dimensional(3D) stereoscopic display is a promising direction of display technology development, and color asymmetry of left and right eye views is a common phenomenon in stereoscopic 3D displays, which can cause visual discomfort. Under the 3D display, the study of binocular fusion of asymmetric colors is an extension and supplement of traditional color vision research, which has a certain scientific significance to understanding the process and mechanism of visual information processing in the human visual system as well as has application value to solve the problem of visual discomfort in existing stereoscopic display technology. In this study, the relevant literature on binocular color fusion was sorted, and the research status of binocular color fusion was summarized from three aspects: binocular color fusion, the interaction between color and stereo fusions, and the influence of binocular color fusion on the visual comfort of 3D displays. We highlight that the interaction mechanism of binocular color fusion and stereo fusion is still uncleart, and the research results stay on the phenomenon description, lacking quantitative experimental data to establish a color fusion model. We infer that binocular color asymmetry affects the visual comfort of 3D displays. In addition, 3D display-based image enhancement may become a research hotspot in the future.
