基于调绘片数字影像的街区式居民地全自动提取

Auto Extraction of Residential Area of Square Based on Digital Identified Photograph

针对当前数字化测图实际生产作业中的需要 ,在图像处理技术和线条跟踪技术的基础上 ,对调绘片数字影像中街区式居民地的全自动提取技术进行了研究和实践。实验表明 ,利用文中所述方法可以大幅度提高街区式居民地的矢量化采集速度。

Aimed at practical requirement of digital mapping, on the basic of the digital image processing and the methods of line tracking, this paper studies a auto extraction method of residential area of square in the digital identified photograph and put it into practice. Experiments show that the method presented improves the efficiency notably.
