A machine vision system is proposed that will identify and locate GPS co-ordinates of defective Raised Pavement Markers along road lane markings. This system will comprise of a mobile data acquisition system, and a separate ofjline image analysis system. In this paper we present a method for road lane marking identification, using a Hough Transform based technique. This paper describes the implementation of the Hough Transform for line detection. Using the Hough Transform algorithm road lane markings are automatically identified, given a scene acquired from a digital camera system. This knowledge is intended to be used to aid current research in the area of defective Raised Pavement Marker detection at 1TB. Results of a sample dataset are presented and discussed
