The system includes at least one map creating device (100) that includes an object recognizing unit (111) recognizing, per frame of the road image, a road facility object including at least one of a GCP object and an ordinary object and a property, a feature point extracting unit (112) extracting a feature point of at least one or more road facility objects from the road image, a feature point tracking unit (113) matching and tracking the feature point in consecutive frames of the road image, a coordinate determining unit (115) obtaining relative spatial coordinates of the feature point to minimize a difference between camera pose information predicted from the tracked feature point and calculated camera pose information, and a correcting unit (116) obtaining absolute spatial coordinates of the feature point.",
