System and method for classification of objects from 3D reconstruction

摘要

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.

主权项

1. An automatic computer method for detecting and classifying manmade objects comprising:
automatically creating, by a computer, a filter to detect differences in characteristics between natural and manmade objects; automatically receiving, by the computer, sonar intensity data, the sonar intensity data including objects and background; automatically selecting, by the computer, manmade objects from the objects and background based on the filter; automatically separating, by the computer, the selected manmade objects from a background by segmentation; automatically creating, by the computer, a 3D reconstruction of the selected manmade objects by melding multiple scans of information about the selected manmade objects; automatically creating, by the computer, feature vectors based on the 3D reconstruction; and automatically classifying, by the computer, the feature vectors into types based on support vector machine technology and clustering technology.
