摘要/Abstract

摘要： 实现了一种基于激光特征点的多通道投影拼接融合软件方法。所用方法为在已知环幕的半径、弧度、高度等几何参数的基础上,在环幕上通过激光点阵列标注出若干特征点,并借助这些特征点求出各个投影仪投影矩阵参数。使用求出的投影参数实现对各个投影仪图像画面的几何校正,并通过色彩融合将多个投影仪的投射图像拼接融合成一副完整的图像显示在环幕上。实验结果表明,该方法解决了操作便捷性和可扩展性的问题,可以稳定有效地实现环幕多投影仪拼接融合。

Abstract: This paper proposes a software method to construct a multi-projector display system. Based on the known geometric parameters of the projection curve surface such as radius, radian and the height of the circular-screen and the laser marking points, this method calculates the projection matrix of each projector to warp the image of each projector correctly. The Alpha blending and gamma rectification techniques are used to do the color blending. The experimental results show that the geometric warping and color blending effects of the seamless multi-projector display system are stable and effective.

Key words: cylindrical display, multi-projector display, warping and blending, geometric warping, color blending
