Abstract

A method and system that can be used for scanning underwater structures. The method and system allow a user to gain a better understanding of an underwater structure. For example, the method and system detect change(s) to an underwater structure. An acoustic sonar wave is directed toward an underwater structure, and a reflected acoustic sonar wave is received and processed to produce a three dimensional image. Data points of this three-dimensional image of the underwater structure are aligned to a pre-existing three dimensional model of the underwater structure. A change detection model is generated based on the aligned 3D images, and the change detection model is compared to the pre-existing three dimensional model of the underwater structure. Based on the comparison, occurrences of structural changes in the underwater structure are detected.
