The dimensioning of lighting installations is performed according to the specifications of CIE documents and relevant standards. Differences are often observed between simulations and experimental measurements regarding the quality criteria and luminance distributions. This paper deals with road lighting quality parameters evaluation between experimental ILMD images and calculations. Influence of image rectification is first examined. Impacts of image resolution, grid resolution and grid positioning on average luminance, overall uniformity and longitudinal uniformity are evaluated. An elliptical method based on human eye resolution and perspective projection is presented for road lighting calculations. It conducts to a good robustness regarding misalignment and give access to a pixel-to-pixel comparison with experimental ILMD images.
