This device plans to combine modern engineering and artificial intelligence techniques with tradi-tional navigation aid products,using a camera module,ultrasonic obstacle avoidance module,GPS navigation and communication module as well as a ten-axis IMU motion detection module to provide navigation services such as reading and object recognition,safe obstacle avoidance,and fall detection and alarm for the blind.In conjunc-tion with the internal resources of Raspberry Pi 4B,the hardware circuit and system software design have been completed,and an overall flowchart is provided.This device can accurately recognize objects and text,and voice broadcast them.It has a high-precision visual recognition and intelligent obstacle avoidance system,and can au-tomatically collect information and send messages in case of incidents other than user falls to achieve the alarm function in real-time.
