Autor: Alina Pranovich, Morten Rieger Hannemose, Janus Nørtoft Jensen, Duc Minh Tran, Henrik Aanæs, Sasan Gooran, Daniel Nyström, Jeppe Revall Frisvad

Publikováno v: Sensors, Vol 24, Iss 21, p 7025 (2024)

The conventional approach to appearance prediction for 3D printed parts is to print a thin slab of material and measure its reflectance or transmittance with a spectrophotometer. Reflectance works for opaque printing materials. Transmittance works fo

Publikováno v: Lyngby, R A, Nielsen, E, De Chiffre, L, Aanæs, H & Dahl, A B 2019, ' Development and metrological validation of a new automated scanner system for freeform measurements on wind turbine blades in the production ', Precision Engineering, vol. 56, pp. 255-266 . https://doi.org/10.1016/j.precisioneng.2018.12.006

Geometrical defects on the surface of wind turbine blades can severely degrade the blade during operation and lead to reduced lift, which in turn reduces the power output of the turbine. This paper presents an automated surface geometry inspection sy

Publikováno v: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XL-5/W8, Pp 7-15 (2016)

Structured light systems are popular in part because they can be constructed from off-the-shelf low cost components. In this paper we quantitatively show how common design parameters affect precision and accuracy in such systems, supplying a much nee
