Pop up: Photo Masking bronze mould from Deansfield

This application enables the creation of a high quality 3D model of an archaeological artefact via process known as photo-masking. There has been a revolution in 3D modelling in recent years and it is now relatively easy to construct such models from ordinary digital photographs. Isolating the object depicted in these photographs, and masking out the background, is an important first step to achieving high quality results. The final 3D model will be made publicly available and is useful not only for basic documentation purposes, but also for graphical displays in museums, for inclusion in gaming and virtual reality environments, or for identifing different sub-styles in otherwise similar types of artefact (that might tell us about the date of the artefact, where it was made, or by whom).

This particular photo-masking application is looking at one half of a bronze mould used for casting palstaves. Its other half is broken into two pieces. A 3D model of the mould will allow us to extract the shape of the palstave which can then be compared to the already modeled axes in a hope of finding a match.

We would like people to draw a polygon around the object that they see in each photograph in order to identify its outline and exclude the image background. This allows the 3D modelling process to concentrate on the object itself and ignore irrelevant background information.

If you are interested in what a 3D completed model looks like, please have a look at the example here for a MicroPasts palstave model.

Thank you!
