本論文主要是設計一個可辨識導盲磚並且幫助引導視障者沿著導盲磚行進的智慧型自走車，為了達到這個目的，必須為自走車設計導航系統，使得自走車能航行在有導盲磚的環境中，自走車透過即時影像處理的技術來達到辨識導盲磚的功能。
自走車使用Netbook電腦(ASUS EEEPC 901)來實行即時數位影像處理技術，並且使用PIC16F877做為控制晶片，人機介面是使用Visual C#.Net 2008所撰寫而成，我們可以透過人機介面對自走車下達指令，自走車是由兩顆直流馬達驅動並且透過RS232與 Netbook 電腦溝通。
自走車上架設1個CCD Webcam 攝影機以擷取影像，並且將擷取到的影像透過USB傳輸至Netbook電腦 (ASUS EEEPC 901)，對CCD Webcam 所擷取到的影像使用即時影像處理技術以判斷影像中是否有導盲磚的存在並且獲得導航資訊，而導航資訊可以作為控制自走車行進的依據，使此自走車能夠達到導引盲人之功能。

The goal of this thesis is to design an Automatic Mobile Vehicle (AMV), the automatic mobile vehicle can recognize the guide-tile and help to guide the visually disabled along the guide-tile. To achieve the purpose, a navigation system must be designed for leading the AMV moving in an environment with the guide-tile. The AMV can recognize the guide-tile via real-time image processing techniques.
The AMV makes use of a Netbook Computer (ASUS EEEPC 901) to do the real-time image processing techniques and makes use of PIC16F877 as its control chip. The Human-Machine interface system is achieved by Visual C#.Net 2008. We can send orders to control the AMV by the Human-Machine interface. The AMV is driven by of direct current motors and communicates with the Netbook Computer through RS232.
A CCD Webcam is set on the AMV to capture the images and transmits the images to the Netbook Computer. The images can use to determine if there is any guide-tile here and extract navigational information through the real-time image processing techniques. The navigational information can be the basis to direct the AMV to move, and the AMV can achieve the purpose to guide the visually disabled.
