摘要	Without increasing the CCD pixels, the super-resolution reconstruction of sub-pixel imaging by increasing the temporal and spatial sampling frequencies in CCDs is one of the approaches to improve the system resolution. However, owing to the increase of sampling frequency, there exists aliasing in data collected by CCDs and blurring in a reconstructed high-resolution image, as a result of which the resolution is far away from the ideal value. To resolve the problem, an algorithm of super-resolution reconstruction, based on sub-pixel imaging achieved by multiple linear array CCDs, is put forward. First of all, an interpolation model on high-resolution grid is established. Next, blur kernels in an image with high-resolution are identified in linear array and scanning direction, respectively to obtain the blur kernel in a frame. Last, the gradient smooth Richard-Lucy algorithm with Neumman boundary conditions is employed to deblur the image and the ringing effects are inhibited as well. Experimental results prove that the gray mean grade (GMG) of super-resolution images reconstructed with the algorithm compared with bilinear interpolation is improved by 7.63, which outperforms in both visual quality and details. Super-resolution reconstruction of sub-pixel imaging in multiple linear array CCDs can be achieved by this algorithm to obtain higher system resolution.
