Although many studies have developed indoor streetscape audit instruments, given the limitation of conventional image information, these have merely been optimized for auditing objective elements of a street. Against this backdrop, this study ascertains whether omnidirectional videos and fully immersive virtual experiences using head-mount displays can be applied to audit the subjective streetscape qualities, thereby replacing the field audit. The study conducts a series of experiments (test audits) using street view images, 360 VR video, and field experience, comparing them using quantitative and qualitative approaches. The results show that VR audit generates results more consistent with the field audit than the street view based audit. In particular, 360 VR video is appropriate for auditing items related to the sense of space, behavioral qualities, and overall street atmosphere. This result unveils the possibility of a recorded VR-based visual assessment survey as a new indoor audit method for evaluating the quality of urban design, which is rarely addressed in existing streetscape audit tools due to its high subjectivity. However, intra-rater agreement estimates of a VR audit demonstrate that its reproducibility remains unreliable. Moreover, a VR audit is less cost-effective than other methods and is not adequate for auditing items that require sensory experience other than the audiovisual. Thus, even if a VR audit can replace much of the streetscape audit, the need for on-site experience remains unlikely to be replaced.

捕捉现实:基于全方位视频的沉浸式虚拟现实作为街景质量审核方法的验证

尽管许多研究开发了室内街景审计工具,但鉴于传统图像信息的局限性,这些工具仅针对审计街道的客观元素进行了优化。在此背景下,本研究确定了使用头戴式显示器的全方位视频和完全沉浸式虚拟体验是否可用于审计主观街景质量,从而取代现场审计。该研究使用街景图像、360 VR 视频和现场体验进行了一系列实验(测试审核),并使用定量和定性方法进行比较。结果表明,与基于街景的审计相比,VR 审计生成的结果与现场审计更一致。尤其是360 VR视频适合审核空间感相关的项目,行为品质和整体街头氛围。这一结果揭示了基于 VR 的视觉评估调查记录作为评估城市设计质量的新室内审计方法的可能性,由于其高度主观性,现有街景审计工具很少涉及这一问题。然而,VR 审计的评估人内部协议估计表明其可重复性仍然不可靠。此外,VR 审核的成本效益低于其他方法,并且不足以审核需要视听以外的感官体验的项目。因此,即使 VR 审计可以取代大部分街景审计,对现场体验的需求仍然不太可能被取代。这一结果揭示了基于 VR 的视觉评估调查记录作为评估城市设计质量的新室内审计方法的可能性,由于其高度主观性,现有的街景审计工具很少涉及这一问题。然而,VR 审计的评估人内部协议估计表明其可重复性仍然不可靠。此外,VR 审核的成本效益低于其他方法,并且不足以审核需要视听以外的感官体验的项目。因此,即使 VR 审计可以取代大部分街景审计,对现场体验的需求仍然不太可能被取代。这一结果揭示了基于 VR 的视觉评估调查记录作为评估城市设计质量的新室内审计方法的可能性,由于其高度主观性,现有街景审计工具很少涉及这一问题。然而,VR 审计的评估人内部协议估计表明其可重复性仍然不可靠。此外,VR 审核的成本效益低于其他方法,并且不足以审核需要视听以外的感官体验的项目。因此,即使 VR 审计可以取代大部分街景审计,对现场体验的需求仍然不太可能被取代。VR 审计的内部评估者协议估计表明其可重复性仍然不可靠。此外,VR 审核的成本效益低于其他方法,并且不足以审核需要视听以外的感官体验的项目。因此,即使 VR 审计可以取代大部分街景审计,对现场体验的需求仍然不太可能被取代。VR 审计的内部评估者协议估计表明其可重复性仍然不可靠。此外,VR 审核的成本效益低于其他方法,并且不足以审核需要视听以外的感官体验的项目。因此,即使 VR 审计可以取代大部分街景审计,对现场体验的需求仍然不太可能被取代。
