【摘要】 大屏幕投影的应用中往往使用多台投影仪拼接,投影图像之间的融合程度,历来是评价拼接效果的重要标准。在分析传统Alpha融合拼接技术基础上,对投影仪投射阶段亮度非线性变化的校正进行了分析,并对Gamma校正方法在投影仪拼接中的使用作了探索。更多还原

【Abstract】 More than one projector is frequently used for large scale screen application.The blending effect of images from separate projectors has always been the crucial criteria of the application.Based on the analysis of traditional Alpha blending method,in this article it analyzes the correction method for nonlinear brightness changes in projecting phase of the projector and gropes the application of Gamma Correction in projectors’ image splicing.更多还原
