本研究采用解混合方法对AVNIR-2和QuickBird影像估算的卷心菜覆盖度进行了精度比较，以增加不同观测日在不同空间分辨率水平下获得的遥感数据量。使用 AVNIR-2 和 QuickBird 图像的分解方法估计的卷心菜覆盖率的准确率几乎相同。这个结果非常有趣，因为它表明我们或许能够利用不同观测日在不同空间分辨率下获得的遥感数据来评估卷心菜覆盖度。因此，使用该方法可以使用不同的遥感图像系统来评估卷心菜生长期间的状况。 (C) 2011 Elsevier B.V. 保留所有权利。
In this study, accuracy comparisons of the cabbage coverage estimated from AVNIR-2 and QuickBird imagery using an unmixing method were carried out to increase the amount of remote sensing data obtained at different levels of spatial resolution on different observation days. The accuracy rates of the cabbage coverage estimated using an unmixing method from AVNIR-2 and QuickBird imagery were almost the same. This result is very interesting, because it shows that we may be able to evaluate cabbage coverage using remote sensing data obtained at different spatial resolutions on different observation days. Thus, it would be possible to use different remote sensing imagery systems to evaluate cabbage conditions during the growing period using this proposed method. (C) 2011 Elsevier B.V.
