AI Vision ASSISTANT CAMERA

The AI vision assistant camera is a smart device for image recognition and interpreta- tion.

Powered by AI, it analyses images from user-defined prompts and generates clear, meaning- ful descriptions. By combining hardware experimentation with advanced AI, the device enables hobbyists to explore vision intelli- gence in practical ways.

Compact yet powerful, it captures images with its onboard camera, sends them to OpenAI through API calls, and performs actions via programmable button functions. These buttons can be configured for tasks such as solving mathematical problems, translating languages, or generating image sum- maries. The device also supports OCR (optical character recognition), image-based translation, and other modes of information extraction.

The system is centred around the ESP32-CAM module with an OV2640 camera, which serves as the primary component for capturing images. These images are processed via the OpenAI API, and the analysed results are displayed on an SSD1306 OLED screen. User interaction is facilitated through buttons that allow functions such as capturing images and triggering Al processing.

Circuit and working

Fig. 2 shows the circuit diagram of the AI vision assistant camera. The circuit uses the ESP32-CAM (U1) as the main controller for both image processing and task execution. An OLED display, HS13L03B2C01, with an I²C interface (U2) connected via SDA (IO14) and SCL (IO15) pins, is powered by 3.3V to present outputs such as text, translations, or image descriptions.
