Abstract:

The detection of remote sensing airport regional objects is of great military and civilian significance.In order to achieve fast and accurate detection results,a data set that is more mission-specific is independently constructed for the detection task.We use the representative network YOLOv3 of the one-step regression global detection method as the basic framework.For the problem of uneven distribution of categories in the data set,the use of generated data isproposed.The method uses generative adversarial networks to perform targeted data expansion to obtain data sets with domain transformation characteristics and more balanced distribution of different types of data.At the same time,the improved DWFPN detection component is used to fusion deeper distinguishable and more robust features.Experiments show that,compared with the original network,the improved network brings 4.98% increase in mean average precision (mAP) and 8.33% increase in average IOU,which reaches 89.07% mAP and 61.97% average IOU,respectively.At the same time,the average detection time of the improved network is 0.0625s,which is 7 times faster than the RetinaNet-101 network with a similar detection rate.Experiments prove the effectiveness of the network and its practicality for specific tasks.
