| 摘 要： | 针对带有异形、多重重叠区域的多投影仪显示系统,给出一种自动、快速的边缘融合方法用于改善投影画面的质量.该方法在对所有投影仪像素级几何标定的基础上,将多投影仪显示系统的边缘融合问题表述为亮度分布全局一致性的非线性最优化问题,并给出一种GPU硬件加速的迭代求解方法.通过理论分析融合区域大小对多投影仪显示系统画面质量的影响,证明本文方法扩充融合区域大小的能力具有重要的工程应用价值.实际应用表明,本文方法能使带有任意形状、多重重叠融合区域的多投影仪显示系统投射出视觉无缝的画面,并利用所有投影仪有效像素使融合区域面积最大化.

| Abstract: | An automatic and efficient edge blending method was presented to improve the imagery quality of multiprojectors display system with anomalistic and multiple overlap regions.Using the pixel-level geometric calibration,the edge blending problem was formulated as a non-linear optimization problem with the object function being the global consistency of brightness distribution.An iterative computing method accelerated by GPU was presented to solve such optimal problem.The theoretic analysis was carried out to d... |
