Castle imaged in extraordinary detail: First image from 3D laser scanner by AOC!

Dunans_0008_smlAOC have just posted a picture of their survey online: here it is and this is what they say about their work:

To fully understand the building and aid the restoration process, AOC was commissioned to undertake a detailed measured survey of the building comprising elevation drawings and floor plans (as much as these could be gained from the present access). By using a 3D laser scanner to complete the work, AOC’s team were able to complete the survey in a single day. 33 scans were completed in total with a final sampled pointcloud of 75 million points, creating a wonderful 3D image of the castle’s exterior. The problems with access to the interior were also partially overcome as the laser managed to shoot through the roofless entrance lobby and upper level windows to identify the basic floor plan; even internal features such as second floor fireplaces were identified, now hanging in mid-air after the collapse of the floor beams within. The survey was accompanied by over 900 high-resolution digital photographs of the external features of the castle to aid the survey and create a detailed record for use during the restoration programme.
