摘要: 以多时相遥感影像几何配准模型为理论基础,研究相对配准误差对高分辨率遥感影像变化检测精度的影响。首先,分析了配准误差和影像波段、地类复杂度之间的关系;其次,研究了相同配准误差条件下,每个不同波段的敏感程度以及不同地类复杂度区域的差异性。实验选取地类复杂度不同的 QuickBird 真彩色影像区域为实验数据,结果表明配准误差对每个波段影响不一致性,并且,配准误差对高地类复杂度区域检测精度的影响更为明显,易产生更多的虚假变化信息。

Abstract: The effects of image misregistration on the accuracy of change detection for high-resolution remotely sensed images were quantitatively investigated on the basis of multi-temporal geometrical registration. The relationship of misregistration respectively with bands and land complexity were firstly analyzed and evaluated. The sensitivity of each band and the difference among each region with different land complexity were then analyzed when misregistration errors are the same. The experimental results using QuickBird true-color images of four regions indicated that the misregistration had different impact on each band, and had more evident impact on regions of high land complexity with more false information generated.
