Background of the project
The smart campus defense software implements an early warning system based on camera data collection, face recognition , mask recognition, and data statistics. This defense system can log in and clock in for administrators through face recognition, and through fixed cameras installed in the classroom , collect images of classmates in the classroom in real time to determine whether they are wearing masks, and then mark them on the monitoring screen to remind security personnel. Use OpenCV/crawler data collection, use Numpy, Pandas and feature engineering, model aggregation for data preprocessing, and CNN model training framework.
