In this video we can see a localization simulation over OpenGL. The virtual robot is represented as red mark over floor and the blue square represent the theoretic field of vision (the second image on the right hand).
The first image on the right hand is the real field of vision and the two small figures are the summary of real and theoretic fields of vision.
Comparing these small figures we can know where is the real robot… so the localization problem is solved!
