BATHYMETRIC TECHNIQUES USING SATELLITE IMAGERY

摘要

Techniques for improving overhead image bathymetry include obtaining depth information from image data based on one or more of the spectral domain, the angular domain (e.g., stereo or photogrammetry), the temporal domain (e.g., monitoring the movement of waves in a body of water), or any other suitable domain, together with a priori information about the area of interest. These different pieces of depth information from the various different domains are combined together using any combination of Optimal Estimation and Continuity Constraints to improve the accuracy of the results.

主权项

1. A computer-implemented method for performing bathymetry of an area of interest of a body of water, the method comprising:
retrieving one or more overhead images of the area of interest; using at least one of a spectral domain, an angular domain, or a temporal domain to obtain one piece of water depth information of the area of interest from the one or more overhead images; obtaining a priori information about the area of interest; and combining the one piece of water depth information of the area of interest with the a priori information of the area of interest to determine a water depth of the area of interest.
