Proveniência
- Close Range Scanning, Knowth. 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 mmAccuracy 0.1 mmAccuracy over distance 0.03% over 100 cmTexture Resolution 1.3 mpColours 24 bppLight Source flash bulb (no laser)Video frame rate 16 fpsExposure time 0.0002 sPost-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.
