METHOD FOR DETERMINING PARAMETERS OF WATER SURFACE OBSERVATION BY IMAGING

摘要

The invention relates to a method for determining an observation parameter associated with a water surface (5) by imaging. Said method includes a referencing step at the end of which a three-dimensional model of an observation site including the water surface (5) is obtained from physical reference points (19) placed on a permanent structure (15) and from virtual reference points (21) placed on a temporary structure. The method further includes an observation step during which the height of the water surface is determined. For this purpose, an imaging device (23) captures images of the observation site, and a data-processing algorithm then determines the coordinates of the water surface (5) using a visual medium (7). The height of the water surface is determined using the three-dimensional model of the observation site. The method further enables the surface velocities of the water surface (5) to be determined.
