通过对比全景VR评价、实景评价及二维照片评价中受试者的感知差异性,分析全景VR评价的优势与劣势及其在视觉景观评价中的应用价值.研究以福州梅峰山地公园中6个典型风景林地为研究对象,通过对比分析受试者的1)观景视角、2)心理指标、3)场景真实感,比较三种视觉景观评价方法之间的异同.结果显示:1)对比受试者在6个风景林地所拍摄的照片,结果显示受试者拍摄的代表性的照片存在差异; 2)受试者在实景评价与全景VR评价中观景视角相似,两种评价方式的观景视角无显著差异; 3)照片评价与实景评价的受试者在心理评价的12个指标中有10个指标存在显著性差异,如:“封闭性”、“宜人性”、“统一性”、“唤醒度”及“场景偏好”等; 而全景VR评价与实景评价对比仅有3个指标(“原创性Sig.=0.036”、“宜人性Sig.=0.025”、“唤醒度Sig.=0.035”)存在显著差异; 4)全景VR评价所呈现的场景现场感显著高于照片评价.表明:1)全景VR评价作为替代照片呈现形式应用于景观视觉评价研究中具有明显优势; 2)对比实景评价,全景VR评价具有变量可控、可重复性及便利性等优势.本研究为全景VR技术服务于景观评价研究提供了理论支持.
By comparing the perception differences of subjects in panoramic VR evaluation,real scene evaluation and photo evaluation,the advantages and disadvantages of panoramic VR evaluation and its application value in visual landscape evaluation are analyzed. In this study,6 typical scenic woodlands in Fuzhou Meifeng Mountain Park are selected as the research objects. Through the comparative analysis of the subjects' 1)viewing angle,2)psychological indicators and 3)scene reality,the similarities and differences between the three visual landscape evaluation methods are compared. The results show that:1)A comparison of photos taken by the subjects in 6 scenic woodlands reveals differences in the representative photos taken by the subjects; 2)The subjects have similar viewing angles in the real scene and the panoramic VR scene,and there is no significant difference in the viewing angle between the two evaluation methods; 3)There are significant differences in 10 of 12 psychological evaluation indicators indicators between photo evaluation and real evaluation subjects,such as:“closedness” and “pleasantness”,“unity”,“awakening” and “scene preference”,etc.; however,there are only three indicators(“Original Sig.=0.036”,“Agreeable Sig.=0.025”,“Arousal degree Sig.=0.035”)that are significantly different between panoramic VR evaluation and real scene evaluation.; 4)The “scene reality” presented by the panoramic VR is significantly higher than the photo. It shows that:1)the panoramic VR evaluation,as an alternative photo presentation form,has obvious advantages in the study of landscape visual evaluation; 2)Compared with the real scene evaluation,the panoramic VR evaluation has the advantages of variable controllability,repeatability and convenience. This research provides theoretical support for panoramic VR technology to serve landscape evaluation research.
