摘要
针对多投影面沉浸式虚拟环境构建过程中几何校正、边缘融合过程的调试和维护繁琐、费时的实际情况,采用基于相机反馈的方法实现了投影面图像在曲面屏幕上的畸变校正以及多投影面画面之间的对齐校正和边缘亮度融合,给出了一种快速构建小型多投影面沉浸式虚拟环境系统的实现方法。最后给出实验结果,证明了此方法对解决多投影面沉浸式虚拟环境系统几何校正和边缘融合问题的有效性。
Some research has been done on the geometric calibration and intensity blending of multi-projection immersive virtual environment, because it may cause trivial time-consuming adjusting and maintaining. The feedback information from a camera was used to calibrate the deformed image projected on the surface, and to align the projection image with each other and to blend intensity on projector overlapped regions. And a kind of method was given for fast building small multi-projection immersive virtual environment system. The experimental results show the method is effective.
