ESTIMATING POSITION AND ORIENTATION OF AN UNDERWATER VEHICLE RELATIVE TO UNDERWATER STRUCTURES
摘要
A method and system that can be used for scanning underwater structures. For example, the method and system estimate a position and orientation of an underwater vehicle relative to an underwater structure, such as by directing an acoustic sonar wave 5toward an underwater structure, and processing the acoustic sonar wave reflected by the underwater structure to produce a three dimensional image of the structure. The data points of this three dimensional image are compared to a pre-existing three dimensional model of the underwater structure. Based on the comparison, a position and orientation of an underwater vehicle relative to the underwater structure can be determined.
