Detection Neural networks are memory intensive, making them difficult to deploy on embedded system with limited hardware resources. To solve the real-time problem of airborne recognition, we introduce a lightweight detection network framework based on the YOLOv3-tiny, that work together to reduce the volume of network by 3× with accuracy increasing by 1% and detection speed reaching 15 fps. The method is based on the YOLOv3-tiny, the size of which is 33.1 MB. Its reference time and mAP are 0.085 s and 78.6%, respectively. Next, we use the structure compression and improved channel pruning strategy to reduce the network volume to 10.33 MB without affecting their accuracy. Considering that model compression will have an impact on the performance of the network, we also adopt some tricks, such as adjusting learning rate and adding attention mechanism, to further improve the identification accuracy, from 78.6% to 79.3%. These measures enable the model to run better and faster on the resource-constrained airborne embedded devices or mobile applications.
