ABSTRACT

This study evaluated the use of low-cost materials for radiometric calibration of multispectral images. Four materials were tested: plywood panels painted with matte paint (M1); plywood panels covered with synthetic nappa leather (M2); Ethylene Vinyl Acetate (EVA) panels (M3), and plywood panels covered with Polyvinyl chloride (PVC) canvas (M4). The useful life of all materials and the errors associated with the calibration was determined. The M1 and M2 panels presented the lowest errors (RMSE), whereas the M4 panels showed the highest errors. Finally, the M3 panels showed the lowest resistance to use, whereas the M1 panels showed the greatest durability.

摘要

本研究评估了使用低成本材料对多光谱图像进行辐射校准的情况。测试了四种材料：涂有哑光漆的胶合板（M1）；覆有合成纳帕皮革 (M2) 的胶合板；乙烯醋酸乙烯酯 (EVA) 面板 (M3) 和覆盖有聚氯乙烯 (PVC) 帆布 (M4) 的胶合板。确定了所有材料的使用寿命以及与校准相关的误差。M1 和 M2 面板的误差 (RMSE) 最低，而 M4 面板的误差最高。最后，M3 面板显示出最低的使用阻力，而 M1 面板显示出最大的耐用性。
