Article Dense RGB-D Semantic Mapping with Pixel-Voxel Neural Network
It seems semantic mapping would be an enabling technology in use of two-body ocean wave energy conversion (WEC) platforms. WEC research has resulted in the use of variable-depth platforms to increase incident wave amplitudes and wave energy density acting on a surface float tethered to the platform. Since the variable-depth platform must be within a few meters of the free surface to obtain optimal concentration of wave energy density, collisions between the surface float and variable-depth platform are an operational concern. Safe separation distances between the taut four-point moored variable-depth platform and low-density surface float are easily achieved, but power takeoff performance will be sacrificed if the variable-depth platform is too deep. Semantic mapping may provide critical feedback to the platform mooring system to optimize safety and power takeoff.

Acoustic and optical sensors could be mounted on the platforms for this application.

There is now a wave energy converter (WEC) design which can create surf offshore. Outer Continental Shelves in water depths greater than 30 meters are ideal for this WEC. Waves 0.3m high can be concentrated to waves over 1.0m high using a variable-depth platform. Autonomous platform depth control is critical for safety and performance reasons. A robust neural network will be required to safely control this quantum increase in kinetic energy input to WEC power takeoff systems
