基于街景大数据的城市感知

Sensing Cities with Street-level Imagery

城市大数据的涌现为感知城市时空动态、评估城市化进程提供了新的途径。街景影像是感知城市物质空间的一种新型地理大数据。近年来， 以深度学习和计算机视觉为代表的人工智能技术不断发展，为挖掘街景语义信息、理解和定量表达物质空间提供了强有力的支持。街景影像不但可以作为遥感影像的补充，以人的视角对城市物质空间进行观测；而且可以表达城市社会空间，反演城市物质空间背后的人类活动状况和社会经济环境，为基于大数据的人地关系研究、建成环境量化研究、空间数据挖掘与知识发现研究提供新的视角。本报告将以城市视觉智能框架为线索，从数据、场景、场所、城市等四个尺度介绍街景影像在城市研究中的若干案例。 

The emergence of urban big data has provided a novel approach  to comprehending the spatial and temporal dynamics of cities and evaluating the urbanization process.  Street view images are a new type of geographic big data that can help us understand urban material space.  Recently, advances in artificial intelligence technology, particularly in deep learning and computer vision,  have enabled us to mine semantic information from street view images and gain a quantitative understanding of material space.  Street view images are not only a supplement to remote sensing images,  but they also allow us to observe urban material space from a human perspective.  Furthermore, street view images provide insight into urban social space,  revealing the human activities and socio-economic environment that underlie the urban material space.  This perspective offers new opportunities for research on the relationship between humans and their environment,  the quantification of built environments, spatial data mining, and knowledge discovery based on big data.  This report, based on the framework of urban visual intelligence, introduces several cases 

that illustrate how street view images have been used in urban research from four dimensions: data, scene, place, and city.
