Paper Abstract
A high dynamic range imaging method of GEO staring imaging is proposed based on radiance simulation
of GEO remote sensing targets and analysis of foreign and domestic remote sensing payload characteristics. Due
to the high temporal resolution of GEO staring imaging, multiple exposure method is used and image sequences
are captured with different integration times; Then a high dynamic range image is obtained after fusion with the
contrast of neighborhood pixel values being the weighting factor. Finally experiments are done in lab with
visible plane array 2048*2048 imaging system for verifying multiple exposure test. It can be proved that using
multiple exposure capture fusion method can obtain an 11 bit high dynamic range image. The essence of the
method is that it sacrifices time resolution in exchange for high dynamic range, which overcomes the defect of
small dynamic range of single exposure and is of practical significance in terms of GEO high dynamic range
information capture.
