本文在总结2004年工作的基础上,以辐射传输理论为基础,改进和增加了地面同步测量邻近效应模型设计和测量参数,实现了航空和卫星数据获取过程的地面同步参数测量。在此基础上,分别对航空ADS40和Landsat-5 TM数字影像进行了邻近效应校正实验,特别对城区ADS40数字影像大气校正和邻近效应校正后的图像做了对比,邻近效应校正的图像较只做大气校正的图像像元值反差更大,细节得到更多增强,图像质量得到一定程度提高。

This paper summarized the works in 2004, and on the base of radiation transfer theory, improved and added the adjacent effect models with ground synchronization measurement and parameters, abtained the ground measurement synchronized with the acquisition of airborne and spaceborne remote sensing data. Moreover, we practised the experiments of adjcent effect correction respectively for ADS40 and Landsat-5 TM data, especially compared the digital images with atmosphere correction and adjacent effect correction. The result is that the contrast of pixels DN of images considering adjacent effect was much larger than those without adjacent effect correction, and the details were enhenced so that the qualities of remote sensing images were improved in a certain extent.
