Abstract

The invention relates to a navigator started based on iris recognition, wherein the navigator includes a navigation device and an iris recognition device in electrical single connection with the navigation device; the iris recognition device comprises: (1) a sampling module; (2) a preprocessing module; (3) a feature encoding module used for extraction and encoding of characteristics of an iris image and including a first LBP operator processing sub module, a second LBP operator processing sub module, a third LBP operator processing sub module and a fourth LBP operator processing sub module; and (4) an encoding matching module. The relationship of a center point with other surrounding neighborhood regions is increased, and image textures with different scales and frequencies can be met; after processing with several LBP operator processing sub modules, under a condition without affecting the relationship of the center point with the surrounding neighborhood regions, the encoding length is reduced continuously, storage space is saved, the calculated quantity is reduced, the recognition speed is improved, the recognition accuracy rate is enhanced, and relatively high robustness is obtained.

Description

technical field [0001] The invention relates to the field of navigator system design, in particular to a navigator based on iris recognition. Background technique [0002] In related technologies, a navigator with an identity verification function usually uses a basic LBP (local binary pattern) operator to extract and encode iris image features. The LBP operator is a method for describing texture features in the grayscale range of an image. It has strong robustness to illumination changes, so it is widely used in image texture feature extraction. [0003] The basic LBP operator is generally defined as: in a 3×3 window by the center point n c and its surrounding 8 neighbors n 0 ,... n 7 composition, where the texture T is defined as: T=(n 0 -n c ,n 1 -n c ,...,n 7 -n c ), binarize it, and use n c As the threshold, the 8 points of the neighborhood and n c Comparison, if the value greater than the center point is marked as 1, otherwise it is marked as 0. The texture...
