Design of Intelligent Guide Wand with Multi sensor Information Fusion
In order to help visually impaired people travel safely and conveniently, and to address the performance limitations of traditional white canes, a navigation cane was designed using a combination of multiple sensors in an intelligent system. This system is centered around the STM32 embedded microcontroller and incorporates advanced signal processing algorithms and multi-sensor technology. When in use, it can measure road obstacles, water ac-cumulation, tactile pavements, zebra crossing guidance, and provide guidance through voice prompts or Bluetooth broadcasting. This enables visually impaired individuals to safely navigate independently with the assistance of the navigation cane.
