Scanning and Processing

My interests in scanning and processing are two-fold; one for data collection purposes, the other to better understand how those data collection methods can introduce error into my work. I regularly use different scanners to collect 3D data and employ a standard suite of post-processing methods to generate the final meshes. More recently, I have begun to explore the variability introduced by different processing algorithms (more on that here), which is aiding in the further refinement of my methodological approach.

Automated computer aided inspection of the same Pontchartrain dart point (and scan data) as above illustrating the results for 3D/2D comparisons, and those for sixteen comparison points. The only difference between the two images, which employ identical data, is the post-processing work flow.

I use the results of each analysis to then refine my post-processing work flow for a specific project, helping me to produce consistent and reliable results. This same methodological approach can be used to identify the best post-processing work flow for mixed-method analyses that employ data gathered using different hardware and software configurations.
