摘　　要：随着用户对于虚拟现实体验沉浸性要求的不断提高,视频透视凭借对环境亮度适应性、视场角大小和虚实遮挡关系等方面的优势,成为当前相比于光学透视更具前景的混合现实技术路线。然而,当前视频透视技术的产品化工作仍处于起步阶段,已推出的混合现实终端在实际应用中存在若干问题。从时间、空间、图像质量三大维度切入,重点围绕图像延迟、视点匹配、视觉分辨率、透视畸变和动态范围5个问题展开分析,旨在为视频透视技术发展提供阶段性总结,理清思路以支持其未来发展。As the demand for the level of immersion in extended reality(which includes virtual reality and augmented reality)continues to grow,video see-through(VST)has become a more promising mixed-reality technique than optical see-through(OST)due to its advantages in environment brightness adaptability,field of view and occlusion implementation.However,a few products equipped with VST have showcased multiple problems as the technique is still in an early phase.Therefore,the analysis has been conducted in the aspects of temporal,spacial and image quality,focusing on problems of image latency,point of view accommodation,oculus resolution,perspective distortion and dynamic range.Hopefully,this paper can provide an insight into VST status quo and facilitate its future development.
