Photogrammetry

I've been using photogrammetry for over 7 years. Texture extraction and millimeter to sub-millimeter tolerances mean photogrammetry is useful for art and engineering applications.

Carbon Fiber Tub

This scan was done for the University of Ottawa super mileage team. The carbon fiber chassis was handbuilt. An accurate model was needed to avoid interference issues when designing the interior assemblies. I wasn't allowed to paint or coat the chassis to make it lighter which made picture dynamic range very low. I ended up using hundreds of colored stickers to get better keypoint detection.

Raw scan data was processed in 3ds Max and then imported into SolidWorks. Mounting point datums were used to calibrate mesh scale.
