摘要
类半球面投影技术提供了井下工作人员模拟培训的完全沉浸可视化体验,基于煤矿救生舱狭长、昏暗的特点,类半球面显示架构更有利于逼真展现救生舱场景特点。主要论述了在类半球面投影中获得鱼眼图像的基本原理,结合鱼眼图像拼接原理和创建鱼眼角度图像2个关键技术,在Unity中应用光线跟踪算法得到煤矿救生舱虚拟场景的鱼眼图像。
Similar hemispherical projection technology provides visual experience of simulation training for underground staff. For the narrow and long and dusky features of life - saving cabin, similar hemispherical display architecture is in favor of clear showing the life - saving cabin of coal mine. The article mainly discusses basic theory of getting fisheye image in similar hemispherical projection, and gets the virtual fisheye image of life - saving cabin by ray tracing calculations in Unity combined with the key technologies of fisheye im- age theory and creating fisheye angle image.
