Optical and SAR Imagery Registration Based on Virtual Searching Window
摘要
Abstract
The imaging mechanisms for optical and SAR imagery is different, which throws a big difficulty in the registration between them.Aiming at above problem, this paper proposes an registration method based on virtual searching window. Based on spatial features of registered imagery, the virtual searching window is constructed, and then the spatial features and gray statistical features are combined together to register optical and SAR imagery. While the algorithm's searching efficiency is guaranteed, its precision is improved. Images of Radarsat-2 and ASTER with big differences in scale and angle are tested. Some features are extracted manually to check the transform model's precision, the results indicate that errors are lower than one pixel, which effectively proves that the algorithm is robust to differences in scale and angle between optical and SAR imagery and has a high precision.关键词
