A road-model-definition system (10) suitable for an automated-vehicle includes a camera (14), a lidar-unit (20), and a controller (24). The camera (14) used is to provide an image (16) of an area (18) proximate to a host-vehicle (12). The lidar-unit (20) is used to provide a point-cloud (22) descriptive of the area (18). The controller (24) is in communication with the camera (14) and the lidar-unit (20). The controller (24) is configured to determine an image-position (28) of a lane-marking (26) in the image (16), select ground-points (44) from the point-cloud (22) indicative of a travel-surface (42), determine coefficients of a three-dimensional (3D) road-model (40) based on the ground-points (44), and determine a transformation (60) to map the lane-marking (26) in the image (16) onto the travel-surface (42) based on the image-position (28) of a lane-marking (26) and the 3D road-model (40) and thereby obtain a 3D marking-model.
