Photogrammetry : boat surveys

Photogrammetric surveying of ships is a complex exercise due to the nature of the objects to be recorded. The advantage of a complete survey, as opposed to a half-hull survey, is that it allows the deformations of the structures to be identified, evaluated and diagnosed.

In the example below, the demonstration is made on a model. The principles and difficulties are identical to a 1:1 scale model, but with much better accessibility. For examples of real boats, see the following pages
