隨著生活品質的提昇，車輛輔助安全駕駛系統，也就變得越來越重要。交通標誌是提供駕駛人關於道路狀況的資訊且根據中華民國交通部交通法規[21]，有90%的交通標誌是含有紅色外框的警告、禁止、限制標誌。在本研究中，我們將一部相機架設在車上，用來偵測紅色的交通標誌，並且辨識速限交通標誌的速度來幫助駕駛人避免超速危險的發生。 In these few decades, the vehicle number is rapidly increasing because people’s incomes are increasing. In addition to the vehicle number, more factors of road situation, driving environment, and human attention result in a large amount of traffic accidents and casualties. If there is a mechanism to help the driver to detect the road situation and driving environment, and then to provide some useful information to the driver in these situations, the danger is therefore avoided. In this thesis, we set up one camera on the vehicle to capture images for detecting traffic sign with red color border and recognize the speed in speed limit traffic sign.
