Abstract

The invention discloses a target detection method based on target space knowledge and two-stage predictive learning, using various data transformation methods to increase the number of samples, increase the diversity of samples, and train SSD and the newly designed RefineNet two deep neural networks network; for prediction targets with higher probability in the preliminary prediction results of SSD, the accuracy of discrimination is further improved through RefineNet; by formulating target-specific spatial structure constraint rules to reduce wrong predictions, the final detection results are obtained. Compared with some existing methods, the present invention takes into account the visual characteristics and spatial characteristics of remote sensing targets at the same time, and uses a deep network with excellent feature extraction capabilities to realize end-to-end target candidate, feature extraction and classification positioning, which significantly improves remote sensing. The detection rate of the target is reduced, and the false alarm rate is reduced.

Description
