Described herein are methods and devices for improved location of any and all underwater structures or equipment installed underwater. In particular, systems are disclosed that combine optical and acoustic metrology for locating objects in underwater environments. The systems allow for relative positions of objects to be determined with great accuracy using optical techniques, and support enhanced location of devices that utilize acoustic location techniques. In addition, location information can be provided by the system even in conditions that make optical metrology techniques impossible or impractical.

Systems, methods, and other embodiments described herein relate to acquiring embedded information from a roadway. In one embodiment, a method includes, in response to receiving a reflected signal resulting from a scanning signal interacting with the roadway, analyzing the reflected signal to detect a roadway signature embedded within the roadway. The method includes computing an identifier of the roadway signature as a function of features associated with the roadway signature that are embodied within the reflected signal. The method includes providing the embedded information about the roadway according to the identifier.

A diver navigation, information and safety buoy system and method. The system and method incorporate a float device, and an ultra-short baseline acoustic array in communication with a diver transponder. The system and method also include a GPS system having a GPS antenna device mounted on the float device. The system also includes an AIS system having an AIS antenna mounted on the float. A diver processor permits a diver's location information to be calculated, and the diver can be navigated to a desired destination.

System, methods, and other embodiments described herein relate to localizing a vehicle on a roadway. In one embodiment, a method includes, in response to detecting one or more indicators of a roadway signature within a reflected signal from the roadway, acquiring a fix on the roadway signature as a function of the one or more indicators that identify at least a segment of the roadway signature. The method includes localizing the vehicle on the roadway by correlating the roadway signature with a signature mapping that identifies a location for the segment of the roadway signature on the roadway.

Techniques are disclosed for systems and methods for video based sensor fusion with respect to mobile structures. A mobile structure may include at least one imaging module and multiple navigational sensors and/or receive navigational data from various sources. A navigational database may be generated that includes data from the imaging module, navigational sensors, and/or other sources. Aspects of the navigational database may then be used to generate an integrated model, forecast weather conditions, warn of dangers, identify hard to spot items, and generally aid in the navigation of the mobile structure.
