| 摘 要： | 针对森林遥感影像测量数据偏差产生的影响难以预估问题,构建污染误差模型对森林遥感影像测量数据偏差的影响因素进行分析。首先选择森林研究样本,利用遥感设备及其工作原理收集遥感影像测量数据,分析样本环境污染、光污染、信号污染3种影响因素,并将其设置为污染误差模型的输入项;其次将不同影响因素下输出的测量数据与真实数据进行计算,得出测量数据偏差的分析结果。实验结果表明,3种不同影响因素作用下产生的数据平均偏差分别为2.15、19.40和71.55 ha。通过纵向对比确定数据偏差的影响排序为:信号污染>光污染>测量对象环境污染,通过横向对比确定设置的3种污染影响因素均为负影响因素。

| Abstract: | Aimed at the problem that it is difficult to predict the impact of forest remote sensing image measurement data deviation,a pollution error model is constructed to analyze the influential factors of forest remote sensing image measurement data deviation.Firstly,forest research samples are selected and remote sensing image measurement data are collected by using remote sensing equipment and its working principles.Three influential factors of sample environmental pollution,light pollution and signal pollution are collected and are set as input items of the pollution error model.Secondly,the measured data output and the real data are calculated under different influential factors to obtain the analysis result of the deviation of the measured data.The experiment shows that the average deviations of the data generated by the three different influential factors are 2.15,19.40 and 71.55 ha,respectively.The order of the influence of data deviation identified by longitudinal comparison as signal pollution is greater than light pollution,and light pollution is greater than environmental pollution of the measurement object.After horizontal comparison,the three pollution influential factors determined to be set are all negative factors. |
