Application of image matching algorithm combined with feature point detection in barrier-free multimediareading
Visual dysfunction not only restricts the action ability of the vulnerable group,but also seriously affects their life,stud-y and work.In order to enable visually impaired people to read multimedia intuitively,naturally and friendly,a barrier-free multime-dia reader was designed based on image matching algorithm and feature point detection,and the performance of the system was veri-fied by image matching experiments and rotation invariance experiments.The results show that the combined feature point detection by image matching algorithm can quickly converge on the data,and can match 675 pairs per second,and the correct matching logarithm and matching accuracy are 179 pairs and 96.24%,respectively.In the case of large rotation,it has good rotation invariance,and vis-ually impaired people can quickly and accurately retrieve the target bibliography when they read barrier-free multimedia,which great-ly improves the reading experience.This study facilitates the study and life of the visually impaired and promotes the construction of a barrier-free and harmonious society.
