ABSTRACT
Since traditional high dynamic range (HDR) imaging technology cannot be directly applied to satellites, in the field of remote sensing imaging, a technology for directly generating HDR remote sensing images on the satellite has been explored for a long time. Based on the above requirements, this paper proposes a multi-exposure remote sensing image fusion algorithm based on spaceborne DSP TMS320C6678 (C6678) to realize this technology. Firstly, three low dynamic range images of overexposure, normal exposure and underexposure are generated by the method of fast continuous shooting by the satellite camera, and the acquired multi-exposure remote sensing images are transmitted to the satellite DSP C6678 for processing. Then the multi-exposure remote sensing image fusion algorithm built in DSP will be used to quickly generate high-quality and high-signal-to-noise HDR images. This technology greatly improves the image information acquisition capabilities of remote sensing satellites and fills the gap in the application of spaceborne HDR synthesis technology.
