基於協同式車間通訊之車道辨識系統

Abstract

車輛所在的車道位置的取得，能夠加強行車的安全及幫助智慧型運輸系統(Intelligent Transportation Systems) 領域的發展，本論文使用影像處理結合車間通訊讓車道上所有車輛取得車輛所在車道位置。前後二台車在同一車道上時，前車在視野沒有受到阻擋的情況下辨識出車道位置後，透過無線網路發送出自己的車牌資訊及所偵測到車道位置，而後車在視野受到阻擋的情況下無法自行辨識出車道位置，此時進行前車車牌的辨識，之後利用辨識出的前車車牌資訊和前車發送出來的車牌資訊做比對，由於與前車在同一車道上，一旦車牌資訊相符，等於是間接地得知車輛所在的車道位置。

The lane position can enhance the safe driving and help the development on ITS(Intelligent Transportation Systems) . In this thesis, we combine Image Processing with Inter-Vehicle Communication to get the lane position. The front car on the lane sends the detected lane position and its license plate information after it detected the lane position by itself. Because of the block of the front car, the back car on the lane can't detect the lane position by itself. At this time, the back car will try to detect the license plate information of the front car on the same lane. The back car will compare the detected license plate information of the front car with the license plate information sent out from the front car. If 2 license plate information are the same, the back car will get the lane position.
