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 a water depth measurement of the area of interest from the one or more overhead images;
obtaining a priori information about the area of interest; and
combining the water depth measurement 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;
wherein the a priori information includes at least one of an estimate of water depth, and an estimate of the type of bottom surface of the body of water in the area of interest.

Abstract
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.
