ANPR-using-DFRobot-ESP32S3-AI-Camera-Module
In this project, the ESP32-S3 AI camera captures an image of a vehicle and converts it into a Base64-encoded string, which is then embedded into a JSON payload along with a natural language prompt requesting number plate extraction. This payload is sent via an HTTP POST request to Google's Gemini API (generateContent endpoint). The Gemini API processes the image and returns a JSON-formatted response, where the extracted number plate (or a relevant message) is found within a nested text field. The ESP32 then parses this JSON response using ArduinoJson, extracts the plain-text number plate, and—if valid—logs it or sends it to Firebase for storage and further monitoring.
The ESP32-S3 AI Camera is a cutting-edge intelligent camera module built around the high-performance ESP32-S3 chip, designed for efficient video processing, edge AI, and voice interaction. Featuring a wide-angle infrared camera, onboard microphone, and speaker, it is ideally suited for applications such as electronic peepholes, baby monitors, and license plate recognition.
