This project was to perform a laser scan on a Kawasaki Ninja motorcycle gas tank and re-surface the general geometry (reverse-engineering). The gas tank was braced onto a wooden frame for convenience, target stickers were placed across the tank, and the scan was completed at 2mm resolution (sufficient for this project). Below we have a screenshot showcasing the step-by-step process of how the scanned tank, from mesh format, is taken into NURBS modeling and reverse-engineered. The reverse-engineered data is highly accurate, smooth, and ready for any type of designing, engineering, prototyping, or even manufacturing.
Technical Notes: in the screenshots below, you will notice a picture of the gas tank in variable triangles, there are some really small, dense triangles around the detailed edges, and larger triangles around the flatter, more predictable areas. This is a "decimated file", a version of the original scan data compressed and reduced in file size for easier workability. Raw, unedited scan files can be extremely huge depending on the geometry, resulting in lagged performance within the CAD software. "Decimation" optimizes the scan data for reverse-engineering without compromising on surface details.
