摘要
设计了一套结合鱼眼摄像头和头戴显示器的新型全景显示系统。采用鱼眼正交投影法建立合适的数学模型, 基于该数学模型合理展开虚拟半球的UV, 将鱼眼图像映射到虚拟半球上, 同时使用双目虚拟摄像头采集已经矫正畸变的图像, 并将其显示在头戴显示器中, 达到头戴显示器全景显示的效果。通过实际测试验证了该方案的可行性。
Abstract
A new panorama display system with fisheye camera and head-mounted display is designed. The mathematical model based on orthographic projection is established. The virtual-hemisphere’s UV is wrapped based on the mathematical model. In the meantime, two virtual camera is used to collect the image displayed on the hemisphere, and the image is displayed in the head-mounted display. The result shows that the complete system is feasible.
