用深度学习分析卫星影像,精准估算古吉拉特邦城市人口。

Population Estimation using Deep Learning over Gandhinagar Urban Area

  • 结合CNN与ANN,从0.3米分辨率影像中识别住宅建筑并估测人口。
  • 在4.8万栋建筑上测试,整体F1分数达0.9936,人口估算为278,954人。
  • 适合城市规划、资源分配等需快速更新人口数据的场景。

人口估计对资源分配和城市规划至关重要。传统调查和普查方法成本高、耗时长且依赖人力。本研究提出一种基于深度学习的方案,利用0.3米分辨率卫星影像、0.5米分辨率数字高程模型(DEM)及矢量边界,估算古吉拉特邦甘德哈纳尔城区人口。方法采用卷积神经网络(CNN)分类建筑为住宅与非住宅,再通过人工神经网络(ANN)进行人口估算。研究使用约4.8万栋建筑轮廓,其中住宅类用于楼栋级人口估计。大规模数据集实验表明,模型整体F1分数达0.9936,成功估算出该地区人口为278,954人。该系统结合高分辨率地理空间分析,支持实时数据更新与标准化评估,克服了传统普查方法的局限性。框架为快速城市化地区的市政部门提供可扩展、可复制的人口管理工具,展现了人工智能驱动地理空间分析在数据驱动城市治理中的高效性。

原文摘要 · Abstract (English)

Population estimation is crucial for various applications, from resource allocation to urban planning. Traditional methods such as surveys and censuses are expensive, time-consuming and also heavily dependent on human resources, requiring significant manpower for data collection and processing. In this study a deep learning solution is proposed to estimate population using high resolution (0.3 m) satellite imagery, Digital Elevation Models (DEM) of 0.5m resolution and vector boundaries. Proposed method combines Convolution Neural Network (CNN) architecture for classification task to classify buildings as residential and non-residential and Artificial Neural Network (ANN) architecture to estimate the population. Approx. 48k building footprints over Gandhinagar urban area are utilized containing both residential and non-residential, with residential categories further used for building-level population estimation. Experimental results on a large-scale dataset demonstrate the effectiveness of our model, achieving an impressive overall F1-score of 0.9936. The proposed system employs advanced geospatial analysis with high spatial resolution to estimate Gandhinagar population at 278,954. By integrating real-time data updates, standardized metrics, and infrastructure planning capabilities, this automated approach addresses critical limitations of conventional census-based methodologies. The framework provides municipalities with a scalable and replicable tool for optimized resource management in rapidly urbanizing cities, showcasing the efficiency of AI-driven geospatial analytics in enhancing data-driven urban governance.
