Abstract

A submarine consists of cylindrical, spherical and conical sections, which are joined together in the construction phase. It has to be checked by measurements whether the sections have been constructed with the required precision. In order to proof to a ship- building company in the Netherlands that traditional measuring methods for quality control can be replaced by photogrammetry a test measurement has been carried out. For this test a conical submarine section has been measured twice. The first time in the traditional way and the second time by using photogrammetry. In the photogrammetric procedure retrotargets, an analytical plotter and a bundle adjustment program have been used. In this paper different measuring methods for quality control will be described shortly. The advantages and disadvantages of each method will be discussed. It will be shown in which way the required object coordinate precision of 1 mm or smaller could be obtained by photogrammetry. It is shown that curvature deviations determined with photogrammetry are almost similar with the deviations as obtained by using the traditional measuring method of the ship-building company.
