Study on supper resolution reconstruction based on staggered arrays
Yuan Zhang, Zhong Xing, Guang Jin · 2011
The image resolution can be improved without increasing the requirement to optical imaging systems' parameters and decreasing the size of CCD pixel by staggered arrays technology, which arranges several CCDs in a specific mode. In this paper, an image super resolution method of improving the image resolution for 1.5 times both in two directions by 4 linear arrays staggered based on this technology is presented, which avoids the large computation in a single time by use of circulation method. This method is proved effective by the digital simulation, and a simulated experiment platform is constructed to test its feasibility. The image resolution is improved for 1.42 times of the unreconstructed image according to the imaging experiment of resolution chart, which is closed to 1.5 times in ideal case. And also, the reconstructed and unreconstructed images are evaluated by the image information entropy, which proves that the reconstructed image contains more information.
