用真实房源窗景图+众包评估,地图化城市窗景感知体验。
City landscape in sight: A crowdsourced framework for unlocking urban-scale window view perceptions from real estate imagery

- 基于1.2万张真实房源窗景图,通过虚拟现实众包比较生成感知数据。
- 发现高层视野更受欢迎且开阔,低层则更安静生动,视域中天空树木占比越高越受青睐。
- 揭示窗景元素影响非线性,过度出现可能逆转正面效果,适合城市规划参考。
住宅窗户所见的城市景观影响生活质量,但城市尺度上真实窗景的感知仍研究不足。本研究利用从中国武汉房地产平台收集的12,334张真实住宅窗景图像(WVIs),这是一种较少被探索的城市视景形式,优于以往研究中常见的渲染或模拟窗景。通过非沉浸式虚拟现实平台,我们基于499张窗景图,从304名参与者处获取了27,477次成对比较,涵盖六种感知维度(如偏好)。训练了一个混合神经网络模型,以预测所有众包窗景图的人类感知并绘制其空间分布。结果显示全城存在显著空间自相关,呈现明显热点与冷点。楼层高度显著影响感知:高层提供更受欢迎且更开阔的视野,而低层窗景则更安静、更生动。推理模型进一步表明,窗景组成至关重要:天空、树木和低层建筑比例高会提升偏好与生动感,而高层建筑比例过高则增加单调与压抑感。重要的是,这些效应呈非线性——某些元素过度出现可能改变其影响方向。该工作推进了对居民视觉体验的城市尺度理解,并提供了一种可迁移、以人为本的方法,可用于改善窗景视觉质量的城市规划与设计。
原文摘要 · Abstract (English)
City landscapes viewed through home windows influence quality of life, yet perceptions of actual window views at the urban scale remain understudied. This study presents an approach for large-scale mapping of perceptions using 12,334 window view images (WVIs) collected from actual residential properties listed on real estate platforms in Wuhan, China, representing a rarely explored form of urban view imagery that offers advantages over the rendered or simulated window views commonly examined in previous studies. Through a non-immersive virtual reality platform, we collected 27,477 pairwise comparisons across six perceptual dimensions (e.g. preference) from 304 participants based on 499 WVIs. A hybrid neural network model was trained to predict human perceptions of all crowdsourced WVIs and map their spatial distribution. Results reveal significant spatial autocorrelation with distinct hot and cold spots across the whole city. Floor level strongly influences human perceptions: while higher floors offer more preferred and extensive window views, lower-floor windows provide residents with quiet and vivid views. An inference model further shows that window view composition matters considerably: high ratios of sky, trees, and low-rise buildings enhance people's preferences and perceptions of vividness, whereas high ratios of high-rise buildings increase perceptions of monotony and oppression. Importantly, these effects are non-linear: the excessive presence of certain elements can alter their impact on human perception. This work advances urban-scale understanding of residents' visual experiences and offers a transferable, human-centric method to inform urban planning and design aimed at improving the visual quality of window views.
