Luminance Uniformity Analysis Based on Digital Camera Measurements

This paper presents a new method for calculating luminance uniformity on the field. The first step of the study is doing the luminance measurements by using a Digital Camera. The second step of the study consists in editing the acquired image to separate the calculation area for which the uniformity is to be studied. Last but not least the final step of the study is to calculate the uniformity. A graphical programme was used for editing of the picture, while the calculations are done with a script in MATLAB R2020. The pictures have been acquired on the Independence Boulevard from Iasi, Romania.
