Abstract
Compressive sensing theory can reduce the cost of image processing, which can be used in many fields. Based on the sparse characteristics of space target image, this theory has a good application prospect in the field of space optical observation. The practical application of compressive sensing contains three steps: sparse representation, coding measurement and sparse reconstruction. This paper applies compressive sensing theory in optical imaging of space target by learning dictionary sparse representation, non-coherent measurement matrix and orthogonal matching pursuit reconstruction. In order to study the effect of this application, the evaluation index is constructed by peak signal-to-noise ratio and structural similarity. The simulation results show that this theory can sense the space target in low data amount and reconstruct the image in a good quality. This conclusion provides a feasible method for the application of compressive sensing in space-borne imaging system.
