BiRD project (2017-2020)

European Metrology Programme for Innovation and Research (EMPIR) project BiRD - "Bidirectional reflectance definitions".

This project aims to clarify how bidirectional reflectance distribution function (BRDF) measurements should be carried out on both classical surfaces and surfaces exhibiting goniochromatism, gloss and/or sparkle visual effects.

Metrology Research Institute's contributions to WP1, WP2 and WP4 are based on competence in the area of material characterisations and assessment of settings of instruments for BRDF and gloss measurements.

Metrology Research Institute will review the state of the art in terms of existing commercial colour management software for colour quality control of surface appearance in collaboration with University of Alicante, Spain (UA). Metrology Research Institute will develop an open source code to plot and to compare BRDF in polar mode, using X, Y, Z representations with inputs from UA. The code will be tested with data provided by other partners and the data obtained in IND52 xDReflect project.

Metrology Research Institute, with support from UA, will develop an open source code to plot and compare the colour travel, an appearance descriptor, in CIELAB space, and a visualisation mode of BRDF data. The code will be tested with data from other activities of the project, and from those obtained in IND52 xDReflect project.
