摘要

本文对意大利利沃诺城市景观的视觉质量进行了评价。利用基于Flickr应用程序编程接口的算法，下载了一张共享照片的7453个拍摄点的坐标。对城市景观的感知进行了直接调查。要评估的地理空间是通过虚拟现实耳机在虚拟现实中播放的78张球形图像来测量的。用主成分分析法对数据进行处理。开发了视觉质量指数(VQI)来对结果进行空间化。计算显著性图，调查高VQI地区的典型模式。研究结果表明，主观视觉感知有助于确定高质量公共空间的设计标准。

Urban landscape assessment: a perceptual approach combining virtual reality and crowdsourced photo geodata

The paper focuses on the evaluation of the visual quality of the cityscape of Livorno, in Italy. Using an algorithm based on Flickr’s Application Programming Interface, the coordinates of 7,453 shooting points of a shared photo were downloaded. A direct survey was conducted to assess the perception of urban landscape. The geographical spaces to be evaluated were measured using 78 spherical images played in virtual reality through a virtual reality headset. The data were processed with the Principal Components Analysis. A Visual Quality Index (VQI) was developed to spatialise the results. Saliency maps were calculated to survey typical patterns in areas with high VQI. The results demonstrate how subjective visual perception helps identifying the criteria for the design of high-quality public spaces.
