Systems and methods for positioning objects in underwater environments are provided. The geolocation of a target for an object is determined, and a light source provided as part of a positioning system is operated to project a visible target at that location. The determination of the target location relative to the positioning system can include determining a location of the positioning system using information obtained from a laser system included in the positioning system. The light source used to project the visible target can be the same as a light source included in the laser system. A location of an object relative to the target location can be tracked by the laser system as the object is being moved towards the target location. The described methods and systems utilize one or more non-touch subsea optical systems, including but not limited to laser systems, for underwater infrastructure installation, measurements and monitoring.

System, 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, analyze 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.

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 sensor fusion with respect to mobile structures. A mobile structure may include multiple ranging sensor systems and/or receive navigational data from various sensors. A navigational database may be generated that includes data from the ranging sensor systems and/or other sensors. Aspects of the navigational database may then be used to generate an integrated model, which can be used to generally aid in the navigation of the mobile structure.

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.

A subsea measurement system (400) comprises a first reference beacon (110) disposed at a first known location, a second reference beacon (112) disposed at a second known location, and an acoustic communications module (302) for coupling to a subsea element to be monitored. The acoustic communications module (302) is capable of moving, when in use, relative to the first reference beacon (110) and the second reference beacon (112). The acoustic communications module (302) also comprises a processing resource and is arranged to determine first range-related data to the first reference beacon (110) in response to receipt of a first signal by the acoustic communications module (302) from the first reference beacon (110) and second range-related data to the second reference beacon (112) in response to receipt by the acoustic communication module (302) of a second signal from the second reference beacon (112).

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.
