System and method for generating vehicle position fixes for an underwater vehicle based on images of a target object on the seafloor. The position of the target object is estimated based on a selected pixel on the target. For each image of the target, there is a different selected pixel, and a different uncertainty associated with the target location based on the selected pixel. Vehicle position fixes for the underwater vehicle are computed based on an analysis of the selected pixels for each target, the uncertainties of the selected pixel positions, the location and uncertainty of location of the vehicle collecting the pixel positions, and other information collected about the target.

System and method for automated bottom feature navigator

System and method for detecting and classifying man-made objects on the seafloor using 3D reconstruction techniques. Enhanced sea floor object detection with classification is provided that is as good as provided by short range optical imagery. This approach eliminates the step of passing off identification to humans, and enhances the speed, accuracy, and safety of present operations in mine detection and neutralization.

System and method for classification of objects from 3D reconstruction

System and method to partition littoral regions by profiles of specific parameters using fuzzy c-mean clustering. Fuzzy cluster partitions assign each datum to a set of data clusters such that the sum cluster membership probability of the point is equal to unity. Partial memberships can supply information about transition areas from one cluster to another.
