This study proposes a model quantization strategy leveraging knowledge distillation to construct a high-precision, real-time detection model tailored for edge devices, such as street-view cameras. By obtaining a teacher model with high accuracy and low inference speed, and a student model with lower accuracy but higher inference speed, knowledge distillation is applied to enhance the student model's detection accuracy by 10.64% in Mask's mAP50, while preserving its inference speed. Compared to YOLO11m, the teacher model achieves an 8% increase in Mask's mAP50. The distilled student model reduces parameters and GFLOPs by 34.98% and 27.43%, respectively, relative to YOLO11m, and by 33.23% and 30.9% compared to the teacher model. This framework offers an effective solution for edge devices in flood monitoring, balancing accuracy and real-time performance.
