| 摘 要： | 目前有多种利用单张高分辨率卫星影像计算建筑物高度的模型,但是其适用条件限制了建筑物高度提取的速度和精度。为了解决这一难题,提出利用建筑物投影同名点线段长度估算高度方法,并结合高分辨率影像数据和实测建筑物高度数据对估算结果进行分析。结果表明计算模型正确、精度较高(绝对误差在2.04 m以内)、使用参数较少、普适性强,在城市灾害评估与预测方面具有较大的实用潜质。

| Abstract: | Height of a building is an important element in the city disaster evaluation and prediction. Up to now, several methods have been developed to estimate the height of a building using single satellite image with a high resolution. However, the accuracy and calculation speed are not ideal for application. To solve this problem, this pape,r developed a new fast method. In this method, the distance between a pair of matched points was used. The result showed that the accuracy of this new method was higher (less than 2. 04 meters) and it could be wildly used in prediction and assessment of city disaster. |
