Abstract:

The installation of new or modified systems on board U.S. Naval combatants during overhauls requires advance planning ship checks. One primary purpose of a ship check is to document existing shipboard conditions in order to develop engineering drawings for the installation of these new systems. Gathering and documenting existing shipboard conditions has always been a very labor intensive effort. Also, accuracy of measurements is restricted by congested spaces, dimensions of extensive length, and intricate configurations of systems. Furthermore, the accuracy of the ship check information relates directly to the quality of the production installation. Accurate well-planned ship check information will reduce production interferences, production costs and schedule variance. One objective of a planning department is to reduce man day expenditures required to accomplish a ship check while increasing the accuracy of the data gathered. Automating this ship check using photogrammetry, specifically stereo photogrammetry, can provide a means to achieve these objectives. This paper will explore the use of stereo photogrammetry to gather ship check data for shipboard distributive systems such as piping, ventilation, cable ways, compartment arrangements and structural components.
