Stereo imagery of the roughness sea surface is one of the most effective tools for remote sensing wave characteristics. Typically, this method is implemented from the decks of fixed oceanographic platforms or onshore structures using two or more calibrated cameras. The topography accuracy from stereopairs directly depends on the quality of camera calibration. With a well-functioning procedure for reconstructing the sea surface from the data of a calibrated stereo system, considerable interest is associated with data obtaining with close accuracy using uncalibrated systems. This work is devoted to the study of this issue using the example of ship stereo survey in the Atlantic. The paper considers the process of image processing from uncalibrated cameras, presents the results of reconstructing the sea surface reliefs at several wind speeds and spatial spectra of long surface waves, and analyzes the practical applicability of uncalibrated systems.
