摘要
讨论了建筑物震害遥感信息的形成机制 ,从遥感图像灰度特征和纹理特征两方面 ,提出了反映建筑物震害信息的特征参数。不同类型训练区的统计分析结果表明 ,灰度平均值、灰度标准差和灰度方差 3种特征参数是建筑物震害识别和分级的良好指标 。
The formation mechanism of seismic disaster information of building in remote sensing image is discussed in the paper. A series of special parameters which reveal the building seismic disaster information are brought forward based on study of the image grey scale and image texture characteristics. Statistical analysis of test image sub_sections of different styles shows the average value, standard deviation and variance of grey scales are the effective indicators for recognition and classification of building seismic disaster in digital images, the texture inverse difference matrix and texture correlation can be used as the supplementary indicators.
