The Real-time Face Recognition with YOLO system operates as an edge artificial intelligence device centered around the MaixCam development board. The workflow begins when the integrated camera module captures live visual data from the environment. This video feed is processed locally on the board using a lightweight YOLOv8 model deployed via Python 3.11 and the MaixPy environment, which has been programmed using the MaixVision IDE. As the neural network analyzes the incoming frames, it performs object detection to locate human faces and applies a 5-point facial landmarking system to map key facial features such as the eyes, nose, and mouth corners. This local inference allows the system to distinguish between known and unknown individuals in real time without needing to offload computations to a cloud server. Based on the classification and recognition results, the MaixCam can output control signals to peripheral hardware. For instance, it can toggle the red and green LEDs to visually indicate status, such as granting access for a recognized face or denying access for an unknown face. The entire setup is continuously powered by a dedicated 5V 2A adaptor, ensuring stable voltage and current delivery to both the development board and its connected indicators during high-load machine learning operations.

Frequently Asked Questions
Running real-time neural network inference like YOLOv8 on an edge vision board demands significant processing power, which draws more current than a standard computer USB port can reliably supply, making a dedicated 5V 2A adaptor necessary to prevent unexpected reboots.
No, model training typically requires high-performance GPUs and is done offline in Python. You then convert and deploy the pre-trained weights to the MaixCam board for inference using the MaixVision IDE.
The 5-point landmarking system pinpoints specific facial features like eyes and the nose to align and normalize the face image before recognition, improving the accuracy of identifying known versus unknown individuals.
