森林资源二类调查中遥感图像增强技术应用研究

摘要

为提高森林资源二类调查中目视判读的质量，以蛟河林业试验区管理局的精校正后的SPOT－5全色遥感图像和SPOT－5多光谱遥感图像为数据源，利用ERDAS9．2遥感处理软件，进行融合处理后，对不同的融合结果进行辐射增强和光谱增强处理后进行目视判读，再利用ENVI5．0遥感软件和MATLAB7．0软件进行定量分析，结果表明：对于SPOT－5遥感图像，先经高通滤波融合处理，再进行直方图均衡化增强处理，是得到高质量遥感图像的最佳选择。%In order to improve the quality of visual interpretation of forest resource survey, the refined adjusted SPOT-5 panchromatic remote sensing image and SPOT-5 multispectral remote sensing images of the administration of Jiaohe forest-ry experiment area were taken as data resource.The visual interpretation was carried after the treatment of radiation en-hancement and spectral enhancement for different fusion result by using the ERDAS9.2 remote sensing treatment software. Then the quantitative analysis was made by applying ENVI5.0 remote sensing software and MATLAB7.0 remote sensing software.The result showed that the best choice to obtain the high quality remote sensing image was made by the treatment of high pass filtering fusion and histogram equalization enhancement for SPOT-5 remote sensing image.
