Improvement methods for YOLO object detection algorithm targeting embedded devices
To address the problem of implementing algorithms on resource-limited embedded devices,a lightweight im-provement is proposed based on the YOLO series of algorithms to adapt to embedded device implementation,specif-ically including:improving the network backbone by introducing GhostNet ideas based on the YOLOv4-Tiny algo-rithm structure to significantly reduce network parameters and computational complexity;strengthening the fusion effect of neck network features to reduce accuracy loss caused by model compression;and using quantization during training to convert network model parameters from 32-bit floating-point data to 8-bit fixed-point parameters suitable for embedded device computation.Experimental results show that after the improvement in this paper,the network's model size relative to the original algorithm is reduced by 57%when the detection accuracy meets application re-quirements,and the power consumption for embedded device implementation is only 3.795 W.
