PROBLEM TO BE SOLVED: To provide a wave measuring system capable of surely extracting waves information by obtaining a relative water level of a side part of a floating body by analyzing an image photographed by one video camera on the body and further correcting the relative water level. SOLUTION: The wave measuring system images a crossing line 3 of a side face 1a of the floating body 1 and a wave motion 2 by the video camera 4, analyzes the image by an image processor 5 to obtain a relative water level, corrects the water level based on response characteristics of the waves of the floating body 1, extracts wave information including an incident wave direction spectrum of the wafer to the body 1, an angle of wave encounter, a significant wave height and a significant period, and displays the information on a display unit 6. |
