A method and apparatus of performing object detection on a path of travel is described. The invention is also related to obstacle detection on railway tracks. Object detection over irregular surfaces or traveling over know paths is also provided. The invention can be applied to railways for obstacle detection on train tracks with a look-ahead sensor system such as a lidar and/or camera system. The object detection may involve the use of multispectral lidar and material identification as well as artificial intelligence for object identification. A reference map is created during a first pass through a virtual tunnel of travel. A vehicle travelling through the tunnel of travel the vehicle will register with reference map and use differences between scans and the reference map to perform object detection. Responses are performed based on the object detection or object identification.
