遥感邻近效应测量与数据分析

2004年和2005年开展了遥感邻近效应的理论研究,2次卫星、1次航空遥感同步试验测量和测量数据分析,在获取了邻近参数的基础上实现了对图像的邻近效应校正。本文介绍了2005年7月25日在官厅遥感实验场沙漠的卫星同步测量实验结果和2005年5月11日奥运场馆建设预留裸土地的ADS40航空遥感同步实验测量数据分析。改进测量方案和测量装置,并且对测量结果进行了对比分析。在两个相邻像元邻近效应分析的基础上,增加了9个点邻近像元效应分析和建立计算公式;在满足高斯条件和影像平坦性要求的前提下,直线高斯相邻点（d=2R）条件下亮度分布交叉点在（d=R）,像元分辨率相互影响约为12.5%,实际测量中亮度分布交叉点和相互影响偏向于亮度值相对低的像元。

Adjacency Effect Measurement and Data Analysis

Supported by NSFC, we have carried out the research on adjacency effect since 2004 and conducted 2 satellite and 1 aerial synchronous experiments. The experiments on May list and July 25th, 2005 and the results analysis were introduced in this paper. With improved measurement design and measurement device, data are analyzed by comparing the spectral curves from ground measurement, flat platform measurement and framed platform measurement, the results show that the improved measurement can prevent more scatter lights to come in the adjacent measurement system. Two adjacent effect analysis results show that if the two pixels have the same brightness there are mutual adjacent influence source and the influence strength is around 12.5% , if the two pixels do not have the same brightness, the influence strength toward weaker pixel, in other word the less brighter pixels get more adjacent effect.
