基于街景图像的滨海景观功能区识别——以大连金普新区为例

The Identification of Functional Areas of Coastal Landscape Based on Street View Images:A Case of Jinpu New Area in Dalian

滨海空间是城市开放空间的重要组成部分,同时也是人类重要的生活和休闲场所,滨海功能区的精准识别、划分及开发利用对沿海城市的发展起着至关重要的作用。文章以大连市金普新区为例,使用U-Net模型及街景图像数据对滨海功能区进行识别。结果表明该模型对滨海街景图像的语义分割效果较好,能够实现功能区的快速识别和滨海景观演化研究,能够为沿海城市滨海空间利用规划和开发提供技术支持。

Coastal space is a crucial component of urban open spaces,as well as vital living and recreational areas for the human being.Accurate identification,delineation,and development of coastal functional areas are pivotal for the development of coastal cities.This paper used the U-Net model as well as the street view image data to identify the coastal functional area in Jinpu New District of Dalian City.The results indicate that the U-Net model is effective on semantic segmentation of costal street view.This method can identify the functional zones rapidly and study the evolution of coastal landscape.It provides technical support for the utilization,planning and development of coastal spaces in coastal cities.
