Artifact-free high dynamic range imaging based on Sandroid Cubesat with camera array

摘要

Space Imaging face serious dynamic range problem. Images captured by conventional cameras will loss important information of overexposed or underexposed regions. In this paper, we proposed a novel HDR imaging method with camera array based on Sandroid Cubesat to obtain accurate images of space target. It has been introduced from two aspects of hardware and software and has been tested the accuracy of variety space conditions in DST environment. Experiments proof that our method can obtain clear and artifact-free images from high dynamic range scene, and it cost only a little computation. As the platform of our approach, Sandroid Cubesat is a small satellite with smart phone cluster as the core. It carries powerful computing capability, which could be used to solve complex image processing algorithms on-board.
