The Bee-Eye: A practical device for measuring the luminance distribution

There are multiple applications in the built environment that can benefit from luminance distribution measurements. However, existing measurement devices have a limited applicability. A luminance distribution measurement device, referred to as the Bee-Eye, is developed based on low cost components that is practical and autonomous. The Bee- Eye, consisting of a single-board computer and camera system, converts the RGB channels, captured using the High Dynamic Range (HDR) technology, to the CIE XYZ color space, because the color matching function y ̅ matches V(λ), the sensitivity of the human eye for photopic vision. Measurements showed that this device is able to measure the luminance distribution for a 180° view with an accuracy ranging from 5% to 20% (worst case).

I received my bachelor degree for architecture in 2014 at Eindhoven University of Technology. 2 years later I received my master degree for building physics and services at the same university. In 2016 I started my PhD at TU/e under the supervision of Rajendra Dangol and Alexander Rosemann, During this PhD we aim to measure lighting quality to serve as input for a control algorithm.
