32. Variances of Cylinder Parameters Fitted to Range Data
Series: Journal of Research (NIST JRES)
Report Number: 117.015
Topic: Materials Science
Published: 9/26/2012
Author: Marek Franaszek
Abstract: Industrial pipelines are frequently scanned with 3D imaging systems (e.g., LADAR) and cylinders are fitted to the collected data. Then, the fitted as-built model is compared with the as-designed model. Meaningful comparison between the two models ...
