Evaluation of the quality of illumination based on the luminance photo and the visualization of the 3D scene
Abstract:
The article proposes a new criterion for lighting quality that extends the existing UGR. The proposed criterion is tested in an experiment on real lighting installations - Moscow metro stations. At metro stations, the spatial-angular distribution of luminance is measured using a camera that shoots in RAW format and a luminance meter. A luminance meter is used to normalize the image to absolute luminance values. In the experiment, observers evaluate the quality of station lighting and compare the results with the calculation of a new criterion. A high correlation of the results obtained by observers and calculated using the new quality criterion is shown. For a few stations, a 3D model is built, and the criterion is calculated according to the model. The article concludes that the quality criterion is applicable to the assessment of lighting quality. Moreover, the proposed criterion can be considered an extension of the existing UGR.
