| 摘要: | 本論文試圖探究如何在少量資料時利用深度學習的方法以衛照影像來進行軍民艦船的判斷，並從圖中偵測出所判別的船艦的位置。
本研究使用的方法除了透過深度學習以及遷移學習(Transfer Learning) 的概念來訓練模組外，鑑於部分分類資料較少也必須用資料增強（Data Augmentation）的方式生成部分資料並加入訓練集，藉以提高整體船體偵測的準確率。
經過不同模型測試與參數調校後，最佳實驗結果得出軍艦AP為0.816、民船AP為0.908，整體mAP為0.862，期許這樣的成果可進一步發展為可輔助軍事判圖人員進行相關作業之系統，提升整體作業效率。
未來以此為基礎希望可以發展更細部的軍事設施判斷模組，進而可以投入其餘判圖種類之應用，完善其判圖系統。
The objective of this thesis is to develop methods to detect and recognize civilian boats and war ships in satellite images based on deep learning approaches when only limited amount of data are available.
The concept of transfer learning is employed to take advantage of existing models. Owing to the restricted availability of certain categorical data, this thesis also used data augmentation techniques to generate and add samples into the training sets to improve the overall accuracy of ship detection.
After extensive model selection and parameter fine-tuning, the average precision (AP) of war ships and civilian boats has reached 0.816 and 0.908 respectively, and the overall mAP is 0.862. The developed framework is ready to be incorporated in a semi-automatic system to assist military personnel in facilitating the efficiency of image detection and interpretation.
This thesis is expected to lay the groundwork for more precise military facility detection models, thus improving efficacy of future military facility image detection systems. |
