Abstract: 本論文中設計一輛可辨識前方是否為可行走區域並沿著可行走之區域行進之智慧型自走車。自走車的導引系統,利用路面紋理辨識道路,使自走車在未知的環境下,取得前方路面紋理資訊作為導引自走車的依據。
In this thesis, an intelligent autonomous vehicle that can recognize the moveable road areas in front of it and move along these roads was proposed. The guidance system of the vehicle uses texture recognition to distinguish the road areas from the environment, which enables the system to utilize this texture information as a basis of guidance in an unknown environment.
The guidance system proposed uses a webcam placed on the vehicle to capture the images of the surrounding field. Next, the images are transformed to a top-down view of the field by a perspective transformation. Then, linear interpolation is employed to improve the image quality. Finally, the LBP algorithm is used to compare the field images with the textures in the database to identify the moveable road areas. Further more, if the texture of road surface is of a random nature, the GLCM algorithm is added to assist recognition. Once the conditions in front are determined, the guidance system will perform corresponding actions to achieve autonomous vehicle movements.
