摘要: For radiometric normalization (RN) of multiple remote sensing (MRS) images within large-scale coverage, the traditional methods ignore the error accumulation and adaptive allocation of cumulative errors caused by the transfer paths in the classical one-after-another pipeline. To this end, a block adjustment-based RN method of MRS images is proposed by considering the global and local radiometric differences (RDs) in this letter. First, the block adjustment-based global RN is conducted to eliminate the global differences of MRS images. This step is independent of transfer paths so that it breaks through the corresponding error accumulation and uneven distribution in the one-after-another pipeline. Second, two local strategies based on block adjustment and edge optimization are further adopted to remove the local residual RDs. In the experiments, it demonstrates that the proposed method can obtain MRS images with a balanced and appealing visual effect, which outperforms the moment matching (MM) method and the popular ENVI software.
