A method for measuring sea state includes scanning an area of a waterborne moving object over a period of time using at least one sensor to obtain point cloud data of the moving object. The area of the moving object is identified based on the point cloud data. Changes in movement of the area of the moving object are characterized over the period of time based on the point cloud data to calculate a state of the moving object. Sea state is estimated based on the state of the moving object.

Sea state estimation

A system and method for determining the distance between at least one point on a vehicle and at least one projected area off of the vehicle includes receiving, with a processor, sensor signals indicative of LIDAR data for the projected area off the vehicle; applying, with the processor, a linear estimation algorithm to filter out noise within the LIDAR data and define a surface plane for the projected area; evaluating, with the processor, the LIDAR data against a vehicle state model; determining, with the processor, the distance between the at least one point on the vehicle and the at least one projected area off the vehicle; and commanding a response in the vehicle controls.
