Abstract
Various arrangements for generating a high definition map are presented. An image of a roadway environment may be captured. A laser imaging detection and ranging point cloud of the roadway environment may be generated. An object recognition process may be performed on the image of the roadway environment to detect one or more objects present in the roadway environment. A fusion process may be performed using the lidar point cloud to identify a location of the one or more detected objects from the image in a vehicle frame of reference. The one or more objects may be mapped from the vehicle frame of reference to a global frame of reference An autonomous driving high definition map may be created that includes the mapped one or more objects in the global frame of reference.
