Enhanced indoor localization with sign-aided visual–inertial odometry

Key Points

• Enhanced indoor localization improves accuracy for navigation systems using visual-inertial odometry and sensor fusion.
• Increased accuracy to 95% was achieved in testing scenarios, demonstrating significant pathways for better indoor navigation.
• Observational analysis applies sign-aided visual-inertial odometry alongside sensor fusion techniques to improve localization effects.
• This significant advance in indoor navigation methods may enable better mobility solutions in complex environments.
