基于高分二号卫星遥感数据的建筑物高度提取

建筑高度信息提取是高分辨率卫星遥感获取城市空间信息的热点问题之一。为了实现建筑物高度信息的高精度提取,提出了一种基于规则信息的面向对象的建筑物高度反演方法。首先根据建筑物阴影几何、纹理、和光谱特征建立基于规则信息的建筑物阴影提取算法,进行建筑物阴影信息提取,再通过计算像元平均值算出阴影长度,构建卫星、太阳、建筑物和其阴影的空间模型反演建筑物高度。采用扬州市两个实验区(佳家花园和杉湾小区)的高分二号卫星遥感数据进行高度反演试验,通过对反演小区的105栋建筑物实际高度测量,对反演结果验证,总体精度为96.5%。表明该方法在城市建筑物高度信息提取方面具有较高的精度。

Abstract

Building height information extraction is one of the hot issues in urban spatial information acquisition by high-resolution satellite remote sensing. An object-oriented building height retrieval method based on the rules of the information is proposed in this work in order to extract building height information accurately. Firstly, the building shadow extraction algorithm based on rule information was established according to the building shadow geometry, texture and spectral characteristics, and building shadow information was extracted. Then the length of the shadow was calculated by computing the average value of pixels, and the building height was inverted by using the spatial model of satellite, the sun, the building and its shadow. Two building height retrieval experiments was carried out based on GF-2 satellite remote sensing data of the two experimental area of Yangzhou (Jiajia garden and Shanwan community). Through the actual height measurement of 105 buildings, the retrieval results are verified and the overall accuracy is 96.5%. It shows that the method has high precision in the aspect of city building height information extraction.
