Building Height Information Extracting Technique Based on PSInSARLIU

  • 摘要: 基于干涉相位的统计分析,给出一种利用高分辨率时间序列永久散射体雷达干涉技术(PSI)提取人工建/构筑物高度的方法。利用给出的测高模型,借助27景高分辨率TerraSAR-X影像获取天津市北辰区典型建筑高度信息,并通过实测值进行验证。结果表明该方法提取的建筑物高度与实测值相互吻合,说明了该方法的可行性与有效性。

     

    Abstract: This article proposed a new model and algorithm for extracting the height of buildings which applied on high-resolution SAR images based on time-series PSInSAR from the statistical analysis of the interferometric phase. We then extract the height of typical buildings in Beichen District of Tianjin with the proposed model and 27 high-resolution TerraSAR images. Statistical results showed that: for high height of man-made objects, the height difference between the value accounted for a smaller proportion of the actual height. For smaller, low height of man-made objects, the height difference between the value for a large proportion of the actual height, the main feature is its small height corresponding to the phase component, greatly affected by noise and model solver errors. Overall, the sampling verification for some typical features of the experimental results and the actual height difference between the mean and standard deviation were 0.8m and 2.1m.The error indicated the feasibility and effectiveness of this method, when compared with result of field survey.
