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.
