The scourge of the seas: A WW1 German U-boat

06/12/2016   |   Oliver Hutchinson

This model was the result of an experiment in using video files to create the dataset to build a model from. A drone flew over the U-boat, abandoned in the Medway, in a variety of directions, heights and distances, capturing footage of the site. From this video we extracted over 300 still images that were processed using Agisoft Photoscan. The whole process took just under 3 hours from start to finish and we now have an accurately scaled model from which measurements can be taken no matter the tide. The survey has helped us to undertake a condition survey of the wreck and provides a baseline for future monitoring. 

As with many 3D models there is a loss of image quality the more one zooms into the frame. In this case it would have been good to supplement the aerial shots with some close up ground based photography to build in more details and textures. Alas, the location of the sub means this is not possible.

How to navigate a 3D model

Click the model to start. You can explore the model by left clicking on it, and while holding down the button drag the camera around. You can also adjust the centre of view by holding the shift key down and clicking and dragging. Lastly, your mouse wheel can be used to zoom in and out.

We look forward to your comments so that we can learn how better to share this type of material with you.
