Block-adjustment and Accuracy Validation for GF4 Patch-images Based on RFM
It is analysed that the geometric characters of specific patch-imaging mode of GF4 which is the first geostationary orbit optical remote sensing satellite of China. And a block adjustment method using average elevation is proposed directing at the specific geometric character that the base to height...

It is analysed that the geometric characters of specific patch-imaging mode of GF4 which is the first geostationary orbit optical remote sensing satellite of China. And a block adjustment method using average elevation is proposed directing at the specific geometric character that the base to height ratio between images is very small. The method constructs the block adjustment model based on rational function model (RFM) and the proposed block adjustment method is employed on the GF4 patch-images without ground control, which solves the low splicing accuracy situation due to some factors, such as low orbit and attitude measurement accuracy, astronomical refraction and lens distortion etc. At last, in two experiments with GF4 real data, it is verified that the accuracy and effectiveness of the proposed method, and the influence of different imagery errors compensated model is analysed also. |
