| 英文摘要 |
| The problem of overlapping occlusion in target recognition has been a difficult research problem, and the
situation of mutual occlusion of ship targets in narrow waters still exists. In this paper, we proposed an improved mosaic
data enhancement method, which transforms the training image stitching into three different scales and inputs them into
the network for training at different scales to strengthen the learning ability of the detection algorithm for local features.
While keeping the test speed constant, the recognition accuracy of overlapping targets is improved, the rate of decay of
recognition ability at different resolutions is reduced, and the robustness of the algorithm is enhanced. The experiments
based on a small mobile testbed proved that, compared to the original algorithm, the improved algorithm improved the
recognition accuracy of overlapping targets by 2.5%, reduced the target loss time by 17%, and improved the recognition
stability at different video resolutions by 27.01%. |
