Lightweight Target Detection Network Integrating Scene Context
A lightweight target detection network that integrates scene context is proposed, effectively solving the problem of poor application of existing detection algorithms in the field of unmanned aerial vehicles. In the design of the network, first, the backbone network of YOLOv3 is replaced with MobileNetV3, and scene information is extracted through the 1×1 convolutional layer. Simultaneously, a scene context module is constructed to filter fine-grained object features. Then, complete intersection over union (CIOU) loss is used to optimize the position error of the bounding box in the loss function. Finally, the algorithm is trained and tested on the newly constructed unmanned aerial vehicle aerial photography data set. Experimental results show that compared with the YOLOv3 algorithm, the average detection accuracy of the proposed algorithm increased by 8.4 percent and the detection speed increased by 5.8 frame/s.
