摘要
针对资源三号多光谱相机,提出利用同时获取的各谱段影像间高精度提取的同名像点建立多光谱相机各谱段对应分片CCD之间的位置模型,求解它们的相对内参关系参数,并应用此模型实现了谱段间影像的高精度谱段配准。试验结果表明该方法能够实现资源三号卫星多光谱影像优于0.3像素精度的谱段间自动配准。
Using high accuracy match points extracted between the multi-spectral images that obtained at the same time,a position model of the CCD chips of the ZY-3 multi-spectral camera was proposed. Relative interior orientation relationship parameters were calculated and accurate band-to-band automatic registration of ZY-3 multi-spectral image was achieved based on the position model, The experimental result indicates that the band-to-band automatic registration accuracy of ZY-3 multi-spectral image is better than 0.3 pixels with the proposed method.
