基于面部表情分析的未来城市声景地图研究--以哈尔滨市儿童公园为例

Research on Future Urban Soundscape Map Based on Facial Expression Analysis: A Case Study of Harbin Children’s Park

研究以哈尔滨一个典型城市公园为例,提出了一种适用于未来城市的智能化声景地图。首先通过对比面部表情数据与传统问卷调查结果,验证了该地图在声景感知质量与声景维度评价方面的有效性;其次,建立了声源、时间与行为等多维度的声景地图,并根据面部表情的变化,使声景地图具有动态的展示效果;再次,通过与传统声景地图的对比,证明了该方案具有客观、高效的优势,并且可以满足政府、设计师及公众对城市声环境的量化需求。综上所述,基于面部表情分析的声景地图预期可以成为未来城市声环境评估与设计的重要工具。

Taking a typical urban park in Harbin as an example, this paper presents an intelligent soundscape map suitable for future cities. Firstly, the effectiveness of the map in soundscape perception quality and dimension evaluation is verified by comparing the facial expression data with the traditional questionnaire survey results. Secondly, a multi-dimensional soundscape map comprising sound source, time and behavior, is established. According to the change of facial expression, the soundscape map has a dynamic display effect. Thirdly, through the comparison with the traditional soundscape map, it proves that the scheme has the advantages of objectivity and efficiency, and can meet the quantitative needs of the government, designers and the public for the urban sound environment. In conclusion, the soundscape map based on facial expression analysis is expected to become an important tool for urban acoustic environment assessment and design in the future.
