Abstract : A problem in modular shipbuilding is the lack of a reliable and quick method of obtaining and utilizing dimensional control in 3D . Photogrammetry has been successfully used as a tool for this application, but because of the large number of systematic errors associated with film- based cameras only very large shipyards have attempted this. Recently, developments in Charge Coupled Device (CCD) imaging arrays for cameras have allowed some success m applying photogrammetric techniques without film in dimensional control. The software and hardware configurations have been expensive and complicated. Digital camera systems and computers were purchased and programmed to tie existing inexpensive software packages with Geometric Dilution of Control (GDOP) error propagation analysis originally designed for topographic mapping into a tool for production shipyard fabrication dimensional control.
