車牌辨識之應用

車輛的發明給人們帶來非常大的便利性，已成為生活中不可或缺的工具了，人們通常追求方便、快速、效率，因此車的數量也越來越多，而發生交通事故的機率也隨之增高，例如：闖紅燈、超速、逆向駕駛、逆向超車、酒駕…等等，又因酒駕而造成重大傷亡的次數屢次增高，所以近年來政府用更嚴厲的手段來取締酒駕，但酒駕再犯率依舊是高。本論文提供一套以車牌辨識的方式來取締酒駕者，首先將曾經為酒駕者的車牌資料紀錄於資料庫內，並在臨檢站前方架設網路攝影機，將即時影像串流透過網路傳送至車牌辨識系統主機中，當車牌辨識系統主機偵測到即時影像串流中車輛的車牌與先前建置在資料庫中的車牌資料一樣時，此時就發出警報告知臨檢站的員警，該車牌的駕駛者曾經酒駕過，請員警提高警覺，並提升員警的執行效率。

The invention of vehicles brings great convenience to people and has become an indispensable tool in life. The number of cars is increasing because of the convenience, speed and efficiency it can bring to people. However, reckless driving leads to increase of the probability of traffic accidents. For example, drunk driving, speeding, improper turn, disobeying traffic lights and signs... etc. In recent years, the number of fatalities caused by drunk driving crashes has risen rapidly. The government attempts to reduce drunk driving by applying the strict policies on prevention measures, with limited success. This paper describes how license plate recognition applied on banning drunk driving violation. The process of this application is described below: All the license plate information of the drunk drivers offenders was recorded in the database. IP Camera will be set up in front of the inspection station and generate real-time video stream which will be transmitted though the LAN to the license plate recognition system. The license plate recognition system detects all the passing vehicles in the real-time video stream. An alert notification will be sent to station polices if the system recognizes same license plate number as built database. This application can enhance the efficiency and effectiveness of drunk driving prevention and enforcement.
