Ottawa Steam Locomotive CN 6200 & Tender; 20mm

3D Model

Steam locomotive CN 6200 and tender outside the Canada National Museum of Science and Technology in Ottawa, scanned quickly at ground level (e.g., the top wasn’t visible) with a Faro Focus laser scanner.

This is the scalar LiDAR (Light Detection And Ranging) data, waiting to be modeled. Notice how the black metallic paint returns less data? The deep black absorbs much of the light (see: black body absorbing electromagnetic radiation) used in the measurements.
