【摘要】 本文以两台投影仪组成的拼接显示系统为例,创新地提出了基于ICC色彩管理机制的颜色调整方法用于实现非重叠投影区域的颜色一致性,并采用分段抛物线插值算法实现投影重叠区域的颜色一致性。本文的具体研究工作包括:①采用矩阵模型,计算生成投影仪的ICC颜色特性文件;②采用3维查找表模型计算生成投影仪的ICC颜色特性文件;③分别利用上述两种方法生成的ICC,通过颜色空间转换实验比较两种ICC的匹配精度,并验证基于ICC色彩管理机制的非重叠投影区域颜色调整方法的可行性;④最后,基于分段抛物线插值算法,借助Quest3D虚拟现实开发平台,验证了投影重叠区域亮度调整方法的可行性。更多还原

【Abstract】 The research on the color uniformity of the tiled multiple projectors display systems gets more and more attention. In this paper, taking the tiled two-projector display system as a case, the color calibration method based on ICC color management mechanism was proposed and used to achieve the color uniformity the non-overlapping projected region firstly. And the sectoring parabola interpretation algorithm was used to achieve the color uniformity of the overlapping projected region. The research content of this paper includes: ①The ICC profile of the projector based on matrix model was calculated and generated; ②The ICC profile of the projector based on 3-dimensions lookup table model was calculated and generated; ③The color-matching precision of the above two types of ICC profiles were compared by the color space conversion experiment, and the feasibility of color calibration method of the non-overlapping projected region based on ICC mechanism was verified; ④ Finally, the feasibility of color calibration method of the overlapping projected region based on sectoring parabola interpretation algorithm was verified by Quest3D development platform.更多还原
