No full textFig. 2.28. Picture for H-RTI digitisation. The highlights on the black spheres allow the algorithm to reconstruct a RTI model.Published as part of Brecko, Jonathan & Mathys, Aurore, 2020, Handbook of best practice and standards for 2D+ and 3D imaging of natural history collections, pp. 1-115 in European Journal of Taxonomy 623 on page 29, DOI: 10.5852/ejt.2020.623, http://zenodo.org/record/375133

No full textFig. 6.14. Ishango rod. The left 3D model was acquired with a µCT many years ago. The middle one is scanned with the MechScan structured light scanner. The right one is the combination of both the µCT scan, the structured light scan and the texture of the photogrammetry model.Published as part of Brecko, Jonathan & Mathys, Aurore, 2020, Handbook of best practice and standards for 2D+ and 3D imaging of natural history collections, pp. 1-115 in European Journal of Taxonomy 623 on page 96, DOI: 10.5852/ejt.2020.623, http://zenodo.org/record/375133
Fig. 6.1. Shell digitised with different methods. The photogrammetry model was captured with a 100 in Handbook of best practice and standards for 2D+ and 3D imaging of natural history collections
No full textFig. 6.1. Shell digitised with different methods. The photogrammetry model was captured with a 100 mm Macro lens and processed with Agisoft Photoscan. The visual comparison of the mollusc shows a similar level of detail between photogrammetry and MechScan for the external surfaces, with still a bit more detail for the MechScan. The HDI Advance has a much lower resolution.Published as part of Brecko, Jonathan & Mathys, Aurore, 2020, Handbook of best practice and standards for 2D+ and 3D imaging of natural history collections, pp. 1-115 in European Journal of Taxonomy 623 on page 86, DOI: 10.5852/ejt.2020.623, http://zenodo.org/record/375133
Fig. 2.17–2.18 in Handbook of best practice and standards for 2D+ and 3D imaging of natural history collections
No full textFig. 2.17–2.18. Two different designs of the ZooSphere. In the first (left) figure, the stepper motor is centered on a long U-shaped axis, a swing, which is controlled by the second axis. In the second figure (right) all of this is more compressed in space and instead of a U-shaped axis to mount the first stepper motor, it is attached to the second by means of a T-shaped rod.
