用计算机视觉从动态古地图视频中提取领土数据
Animated Territorial Data Extractor (ATDE): A Computer-Vision Method for Extracting Territorial Data from Animated Historical Maps
- 基于颜色分割与像素计数，自动识别领土范围
- 处理10个中国朝代（公元前200年-1912年）的动画地图，生成逐年数据
- 无需地图文件，适合教学与初步分析
我们提出Animated Territorial Data Extractor (ATDE)，一种从动态历史地图视频中提取定量领土数据的计算机视觉工具。ATDE采用基于HSV的颜色分割、RGB通道过滤及直接邻域滤波，识别并统计代表领土控制的像素。结合时间对齐与跨视频缩放预处理，该流程将动画视频转化为结构化的时间序列数据。我们在十个中国朝代（公元前200年–1912年）上验证了该工具，生成了与历史趋势相符的逐年像素计数。尽管不能替代权威历史数据集，但ATDE适用于教学演示、初步数据探索及领土动态的比较分析。该工具无需预先存在的矢量地图文件，仅需设定颜色和基本配置即可应用于任意动画地图视频。代码与示例已开源于GitHub。
原文摘要 · Abstract (English)
We present Animated Territorial Data Extractor (ATDE), a computer vision tool that extracts quantitative territorial data from animated historical map videos. ATDE employs HSV-based color segmentation, RGB channel filtering, and Direct-Neighbor Filtering to identify and count pixels representing territorial control. Combined with preprocessing for temporal alignment and cross-video scaling, the pipeline converts animated videos into structured time-series data. We demonstrate the tool on ten Chinese dynasties (200 BCE - 1912 CE), producing year-by-year pixel counts that align with expected historical patterns. While not a substitute for authoritative historical datasets, ATDE is well-suited for educational demonstrations, preliminary data exploration, and comparative analysis of territorial dynamics. The tool requires no pre-existing shapefiles and can be applied to any animated map video given seed colors and basic configuration. Code and examples are available on GitHub.
