多投影显示系统的几何校正及边缘融合技术研究与实现

Research and Realization of Geometry Calibration and Edge Blending for Multi-projector Display System

多投影显示系统是解决人们对高分辨率显示需求与单台显示设备分辨率有限之间矛盾的有效方法.在使用普通数码相机对多投影显示系统进行几何校正的基础上,采用非线性融合函数对相邻投影图像进行边缘融合,实现了多台投影仪的无缝拼接显示.该系统仪器设备成本低廉,软件操作简单快捷,能够有效应用于大屏幕显示,为用户提供高分辨率、超大视域范围的沉浸式体验.

Multi-projector display system is considered to be an effective technique to tackle the conflict between the increasing demands for super-resolution display and the resolution limitations of a single display equipment.This paper adopts non-liner fusion function to edge blending for adjacent projection images to achieve multi-projector display system after using ordinary digital camera for geometric correction.The system can effectively be applied to the large screen display with low-cost equipment and the simple software operation to provide users with high-resolution,super vision of immersive experience.
