All figures (14)
Figure 4. Example of a 3D model with the associated acquisition frames, which shows a typical path for a small object.
Figure 5. Outline of our normal fitting correction.
Figure 12. The gold Buddha model.
Figure 1. Overview of the presented framework, that covers the whole chain from the 3D digitization of real CH artifacts up to the Web publishing of the resulting digital 3D copies for archiving, browsing and visualization through Internet.
TABLE I. INFORMATION AND TIMINGS FOR VARIOUS ACQUIRED OBJECTS.
Figure 10. The Strawberry model rendered with and without color, and with and without normal map.
Figure 9. The Gargoyle model rendered with and without color, and with and without normal map. Bottom row: close-up on the tail details.
Figure 6. Comparison of texturing obtained by a naive averaging of all input frames (top row) and the proposed approach using weighting masks (bottom row).
Figure 7. Color reconstruction for the Elephant model.
Figure 2. The in-hand scanning device used during the first step of the presented workflow, producing the data flow required for the generation of cultural artifacts digital copies.
Figure 13. Rendering examples of our 3D digital artifacts using the SpiderGL library on an common Web browser.
Figure 8. Differences induced by our constrained fitting on the normal computation for a region with a good sampling (top row) and a region with a poor sampling (bottom row). From left to right: initial mesh normals; normals from unconstrained fitting; normals from our constrained fitting.
Figure 3. The diffuse color texture is computed as the weighted average of all video frames. Weights are obtained by the composition of multiple elementary masks, each one corresponding to a particular criterion related to viewing, lighting or scanning conditions.
Figure 11. The white Buddha model.
