CT reconstruction and structured light scan of a small wooden block

Summary

This submission contains a reconstruction from a tomographic dataset and a structured light scan of a small wooden block.

The data is made available as part of [Bossema et al., 2023] and is meant to serve as a practice dataset for the Blender plugin that is published along the article. The code for the plugin can be found here and on github.   

Apparatus

The CT dataset is acquired using the custom-built and highly flexible CT scanner, FleX-ray Laboratory, developed by TESCAN-XRE, located at CWI in Amsterdam. This apparatus consists of a cone-beam microfocus X-ray point source that projects polychromatic X-rays onto a 1944-by-1536 pixels, 14-bit, flat detector panel. Full details can be found in [Coban et al., 2020].

The structured light scan was acquired using an Artec Spider.

Sample Information

The sample is small wooden block (6x5x3cm).
