宽波段成像仪上搭载了一个双通道长波红外相机，采用推扫方式成像。分析了相机获取的2个通道遥感图像存在的3种失配变换类型，结合 SIFT 特征算子，给出了一组配准参数，配准精度达到亚像素级，满足了利用双通道遥感数据和分裂窗算法反演地温的需求。

A dual-channel LWIR camera is mounted on the wide-band imaging spectrometer, using push-broom imaging mode. This paper analyzes the three kinds of mismatch transformations of the dual-channel remote sensing images acquired by this camera, and gives a set of registration parameters with reference to the SIFT. The sub-pixel registration accuracy meets the need for surface temperature inversion using the dual-channel remote sensing data and split-window algorithms.
