Poole WAddon Hill Brooch –
Brooch in Poole Museum, Keith S Jarvis, DMAG Proceedings Vol 104, 1982
Poole Museum Accession number T:2021.193 . A bronze brooch, said to be from Waddon Hill (ST 447016), is now in the Poole Museums collection. The brooch has the pin missing and may be compared with the aucissa type since the head, ribbing and foot-knob are of this form although the profile is not sufficiently bowed. The find is consistent with the early Roman military occupation known on this site. KEITH S. JARVIS – 1982
It is believed this is one of the earliest finds from the fort, made in the late 1870’s by quarrymen working at the site, and passed to the landowner of the time, Mary Cox of Beaminster Manor House. It was handed round as an example of finds at the site, by Boswell-Stone at his 1892 lecture at the Bridport Literary Institute. The photo on the right is from Poole Museum website.
Photogrammetry Model – … Use the button, not escape to exit fullscreen !
The colour balance needs a little adjustment, as the colour in the Poole Museum website image is closer to reality.
Model with missing pin drawn in.
Model only using IR scanner and its camera
The detail on the surface texture is not as precise as the photogrammetry model, and the colour is too brown.
Ring – we are still learning !
This medieval gold ring was scanned with the infrared scanner, but the result is not useable. There are two issues, with very small objects, even though the scanner can resolve to about one fifth of a millimeter, that is still not good enough for very small objects, and the reflective surface did not help the IR process. The scaner visible light camera also is not good enough resolution for a texture on very small objects. We should have just used photogrammetry for this one !

This is what the 3D model below should look like. This image is from the Poole Museum collections website.
