The proposed system integrates advanced technologies to enhance mobility and safety for visually impaired individuals. It utilizes a GPS module to fetch real-time location data of the blind person, sending this information to a server or cloud for access by close ones. The environment is recognized by capturing images with a camera module, and a neural network processes these images to identify objects and surroundings, displaying this information on a display module for easy understanding by the close ones. Crucial details such as the blind person's location, name, and blood group are shown on the display, sourced from a pre-defined database or cloud storage. The system also includes a microphone for receiving voice commands or feedback, and it employs text-to-speech functionality to relay recognized environment details to the blind person. Seamless integration between all modules is ensured, with communication protocols like Wi-Fi and Bluetooth connecting the ESP32 board to the cloud/server for real-time data transmission.
Components Required:-
1. Display Module
2. Camera Module
3. Microphone
4. Wi-Fi
5. Speaker (for audio feedback)
6. Ultrasonic sensor
7. Buzzer
8. Sipeed Maixduino MCU
Methodology:-
The blind person guidance system integrates several key modules on an ESP32 development board with an AI accelerator (Sipeed Maixduino MCU). Using GPS and Wi-Fi connectivity, the system fetches and communicates the blind person's real-time location to caregivers. A camera module equipped with neural networks detects and analyzes the environment, identifying objects and obstacles. Information such as the blind person's location, name, and medical details is displayed on a dedicated module for caregivers. Simultaneously, a microphone captures surrounding sounds, while an AI algorithm processes this data to provide spoken feedback through a speaker, offering navigation directions and alerting to potential hazards. Additional features include ultrasonic sensors for obstacle detection and a buzzer for immediate alerts, ensuring comprehensive assistance and safety during navigation.
