| Summary: | Mindener Museum's Lapidarium incorporates a collection of stone work like reliefs, sculptures and inscriptions from different time
epochs as advices of the city's history. These gems must be protected against environmental influences and deterioration. In advance
of the measures a 3D reconstruction and detailed documentation has to be taken. The framework to establish hard- and software must
match the museum's infrastructure. Two major question will be answered. Are low-cost scanning devices like depth cameras and
digital of the shelf cameras suitable for the data acquisition? Does the functionality of open source and freeware covers the demand
on investigation and analysis in this application?<br><br>
The working chain described in this contribution covers the structure from motion method and the reconstruction with RGB-D cameras.
Mesh processing such as cleaning, smoothing, poisson surface reconstruction and texturing will be accomplished with
MeshLab. Data acquisition and modelling continues in structure analysis. Therefore the focus lies as well on latest software
developments related to 3D printing technologies. Repairing and finishing of meshes is a task for MeshMixer. Netfabb as a tool for
positioning, dimensioning and slicing enables virtual handling of the items. On the Sketchfab web site one can publish and share 3D
objects with integration into web pages supported by WebGL. Finally if a prototype is needed, the mesh can be uploaded to a 3D
printing device provided by an online service. |
