| 摘 要： | 从原始遥感图像几何畸变特征出发，建立了SeaStarStarSeaWiFS和NOAA AVHRR遥感图像数据重采样的一种快速算法，并提出了邻点权重重采样方式。该种快速长法能有效地提高遥感图像几何校正的速度，并适用于连续对地观测系统遥感数据的重采样过程。邻点权重重采样方式可用以替代通常的最近邻点和双线性插值采样方式。

| Abstract: | A method for fast resampling of remote sensing imagery has been developed based on the nature of the geometric distortion of raw imagery. The method was applied to resample SeaStar SeaWiFS and NOAA AVHRR images. Examples of the resampling of SeaStar SeaWiFS images are presented by using the results have shown that the resampling using the method suggested in this paper is much faster than other resampling methods. A weighted neighbour intensity interpolation has also been proposed. The quality of the resampled images is improved. The weighted neighbour intensity interpolation. Advantages of the weighted neighboun intensity interpolation over the nearest-neighbour and bilinear intensity interpolations have been discussed. |
