The Landscape Perception Study and Flowing Scenes Setting of Historic Towns Based on the 'Bag of Photographic Words' Model: A Case Study of Qingyan Historic Town

  • 摘要: 历史城镇游客景观感知研究可从主客交互角度识别游客对历史城镇遗产对象与场所空间的感知规律,指导城镇遗产保护与空间更新。本文基于文献信息学词袋模型和计算机图形学全卷积网络图像语义分割技术,创建了基于网络影像数据机器识别和主题聚类分析的历史城镇游客景观感知“影像词袋”研究方法。该方法以6大景观类型和7组影像属性为要素词汇,以影像拍摄年代、季节情境和拍摄者旅行模式、生命周期为词袋标签,通过词典构造、词袋生成、偏好表征、规律解析为研究步骤。在此基础上,文章通过对贵州省贵阳市花溪区青岩古镇的样本分析,识别出游客对历史城镇的景观感知具有“感知退化”和“四季交感”的规律,其退化程度与交感方式受游客游览模式和生命周期因素影响。在此基础上,文章从人本视角出发,提出了响应游客景观感知规律的历史城镇多元场景营造策略,以期为相关研究提供参考。

     

    Abstract: The tourist landscape perception study of historic town is helpful for understanding the tourist's perception logic to the town's heritages and spaces from the perspective of 'subject-object interaction', so as to provide guidance for the heritage preservation and spatial renewal. Based on the principle of 'word bag' model and fully convolutional networks for semantic segmentation in computer graphics, this paper constructs a 'bag of photographic words' analysis method for public landscape perception study of historic towns. The method based on thematic cluster analysis of internet big image data, takes image dictionary construction, word bag generation, preference expression, perception law analysis as implementation steps, and extracts six landscape elements of layout, street, architecture, environment, customs and product, and also six image attribute characteristic describing elements which are original-derivative, natural-artificial, material-immaterial; overall-partial, concise-complex, vitality-quiet; photographing, recording, documentary were proposed for specific analysis, and use era, season, photographer's travel mode and age as the grouping labels for the bag of words research. Taking the Guizhou Qingyan Town as a sample, the paper analyzes various kind of situation and crowds, and finds that the public perception of the historic town landscape has the laws of 'perception degradation' and 'subject-object interaction', and the perception characteristics are affected by different experience pattern and age factors. Based on the above conclusions, the article further proposes flowing scenes setting measures for the historic towns that respond to the tourists' perception law from people-oriented perspective, so as to provide reference for relevant studies and practices.
