交通號誌辨識在智慧型駕駛中扮演著很重要的角色,能夠即時提醒,並提高行車時的行車安全。本篇論文提出基於類神經網路的學習方式,利用regional occlusion mask的方法,達到改善對於遮蔽交通號誌因遮蔽的關係而失去號誌整體特徵,導致辨識錯誤的問題,並且提高辨識時的準確度。本篇系統也對遮蔽號誌做全域性和區域性的特徵學習,遮蔽號誌透過全域性的特徵學習後,再經由對遮蔽號誌五個區域做區域性的學習,目的是希望能夠解決部分遮蔽的影像所帶來失去整體特徵的問題,我們也利用自己收集的號誌影像(以台灣的北市、新北市)區域為主、德國公開的資料集GTSRB來做實驗。
Traffic sign recognition is very important in the intelligent driving. It enables to remind drivers in real time, and enhance the driving safety. In this paper, we propose a method based on the neural network learning, utilizing the regional occlusion mask method, to improve occlusion traffic sign recognition. This paper utilizes global and local to learn feature of occlusion traffic sign, after learning global feature of occlusion traffic sign, then learning for five local regions of occlusion traffic sign. It expect to solve partial occlusion image, to lose the whole feature problem. We also collect traffic sign images from Taipei City and New Taipei City of Taiwan. The proposed system is tested by our own dataset and German public dataset. The experimental results are promising.
