| 摘 要： | 针对ADS40影像从Level 0级到Level 1级的间接法纠正过程中,最佳扫描行搜索效率低下的问题,在深入研究ADS40影像成像规律的基础上,提出一种基于位置传播的ADS40L0级影像最佳扫描行快速搜索算法。一共采用了4景ADS40影像数据对算法进行验证并与传统二分法实验结果进行对比。结果表明,文中方法平均搜索效率为二分法的6.66倍,平均匹配率为99.99%,验证了算法具有高效性和精确性。

| Abstract: | Aiming at the low efficiency problem of searching best scan‐line for rectifying L0 ADS40 image to L1 image by indirect method ,it proposes an efficient scan‐line searching method based on a best scan‐line position propagation strategy on the basis of studying ADS40 images imaging principle in depth .Four ADS40 image data sets are used to evaluate the performance of the proposed method and the results are compared to the results obtained with traditional binary‐search method .The experiment results show that proposed method is 6.66 times faster than traditional binary‐search method ,w hile keeping the matching rate on 99.99% ,as a result of w hich the proposed method is efficient and accurate . |
