THREE-DIMENSIONAL CONTROL OF SHIP CONSTRUCTIONS

It has recently been acknowledged that the photogrammetric measuring methods which have been developed mainly for mapping purposes are a most advantageous, sometimes even the only possible solution to various problems in the field of engineering survey. This publication contains a description of a research project dealing with a photogrammetric measuring method suitable for the measuring and controlling of constructions. A remarkable part of the research project consisted of an experiment work in which the shape, size and compatibility of two shipblocks was measured using three different metric cameras. Computations were performed using a general three-dimensional adjustment software, which was one of the results of the project. The results obtained with the three cameras and the accuracy of the results were compared with each other and with the results obtained by geodetic measuring methods. The standard error of one coordinate determined by the photogrammetric measuring method was plus or minus 2 mm. Serious attention was paid to the presentation of the results on a digital plotter. Included are some examples of the graphical presentation of the results obtained in the experiment work. The drawings are colored for better readability.
