Research on Tactile Image Reconstruction Algorithm for the Blind Based on Corner Matching

in the tactile substitution vision system, the visual image information of the blind which is collected by using the camera is limited and this limited tactile information will lead to errors in the judgment for the blind. In this paper, corner matching is used as a feature and the image mosaic method is used to realize the reconstruction of tactile image of large view field. The experiment results show that the visual field of the spliced visual image is enlarged and the amount of information displayed is also expanded.
