摘　　要：虚拟现实技术是头戴显示技术的一个重要分支。为了提高虚拟现实头戴显示装置的视场角,获得更高的沉浸感,设计了一种基于视场拼接原理的大视场虚拟现实头戴显示装置。利用4套横向视场角为80°,且完全相同的目视光学系统,通过拼接实现大视场虚拟现实头戴显示。本装置的双目横向视场角为162°,其中每个单目系统的横向视场角为126°,双目重叠视场角为90°。Virtual reality is an important head-mounted display(HMD) technology trend. A large field of view(FOV) virtual reality HMD device is designed based on the principle of FOV stitching for a wide FOV angle and a good sense of immersion. It is realized by stitching four sets of visual optical systems with a same horizontal FOV angle of 80°. This device achieves a binocular transverse FOV angle of 162°, where the transverse FOV angle of each monocular system is 126° and the overlapping FOV angle of the binocular system is 90°.
