Abstract
Real-time detection of targets by video satellites is widely applied for civil and military purposes, but spaceborne platforms are generally limited in memory and computing capacity, with tougher demands on detection algorithms, which can hardly be met by traditional target detection algorithms. Therefore, this paper proposed a lightweight target detection algorithm based on YOLO v3 framework and lightweight neural network MobileNet v3. Compared with YOLO v3, the size of the improved network is reduced by 2.9 times at the same level of detection precision. Experimental results showed that the detection speed of the improved lightweight network could reach up to 40.35FPS, with the mean average precision (mAP) of 87.8%.
