摘  要:
针对如何有效利用高空间分辨率航空影像提取林地信息的问题,根据航空影像的特点,提出了基于影像新归一化植被指数(光谱特征)和形态学梯度(纹理特征)的融合模型。通过实验测试并验证了特征融合模型利用航空影像提取林地信息的效果;分析了航空影像的光谱特征和纹理特征对林地信息提取精度的影响.。结果表明:融合方法能够有效的利用航空影像提取林地信息,其最大加权单类分类成功指数达到97.36%,提取林地信息精度优于非融合方法。

摘  要:
According to the problem of extracting forest information based on aerial photograph,we established a features fusion model with spectral information and textural information. We experienced the result of the features fusion model by using aerial photograph. We studied the spectral information and textural information influencing on the accuracy of extracting forest information,and we verified the result of simulation with the weighted individual classification success index of 97. 36%.The features fusion model of extracting forest information based on aerial photograph is available to extract forest information subassembly.
