Description

South-Cross-perspective-view-1 intro

SMR No.: OF005-016----

Monument Type: Cross - High cross

A ringed sandstone cross about 12 feet (3.7m) high, the South Cross is covered mostly with abstract ornament in the form of interlacing, fretwork, spirals and bosses. It has a Crucifixion scene in low relief unusually placed on thewest face of the shaft rather than the cross-head itself. There are worn depictions of humans and animals on the base. In style it appears to date from the mid 9th century.

Technical Details

3D Capture Method: Close range Scanning

3D Capture Description: The Artec EVA scanner is used to generate high resolution models of surfaces with small scale detail. The Artec EVA uses structured light to record. A forensics tent is used to create a controlled lighting environment and ensure measurement can proceed regardless of the weather when used outdoors. Scanning is undertaken with the fastest speed setting (15 frames per second) and with a minimum 400 mm depth of field. The data is recorded with sufficient overlap between scans to ensure easy registration.

  • Resolution 0.5 mm
  • Accuracy 0.1 mm
  • Accuracy over distance 0.03% over 100 cm
  • Texture Resolution 1.3 mp
  • Colours 24 bpp
  • Light Source flash bulb (no laser)
  • Video frame rate 16 fps Exposure time 0.0002 s

Post-processing is done in Artec Studio 9 software: individual scans are edited, aligned, before a final surface is generated using global registration, fusion, and a small objects filter algorithm. If required, a textured surface can also be created. The model is exported from Artec Studio 9 as an .obj file. For dissemination purposes a 3D pdf of the model is generated using Geomagic Studio 2012.

Data Processing Software: Artec Studio 9 & Geomagic Studio
