Region Transformation<\/strong>
\nMeasuring road glare requires assessing the longitudinal uniformity, overall uniformity, and average luminance of the road surface. According to the IEC 60050-841: 2014 (GB 5700) standard, the measurement points on the road surface must be evenly distributed. When using a glare luminance meter for road imaging, the road surface appears as a trapezoidal region in the luminance image. To address this, the software provides a quadrilateral-to-rectangle transformation algorithm for luminance uniformity analysis.<\/p>\n

Automatic identification and classification of light sources<\/strong>
\nGlare evaluation requires information on the spatial position, solid angle, average luminance, and illuminance of each light source. Therefore, the glare luminance meter features a luminance threshold-based light source identification algorithm, which can detect, label, and classify each light source. Based on glare calculation standards, the algorithm determines whether each light source should be included in the glare measurement results.<\/p>\n

Flickering light source correction<\/strong>
\nIn China, the power supply frequency for electric light sources is 50-60Hz, resulting in a flicker period of approximately 10Hz. For glare measurements, the exposure time for luminance measurement is typically set at 1\/1000s, which is much shorter than the flicker period of the light source. This fluctuation in light output significantly affects the repeatability of glare measurement results. Our provided flicker light source measurement mode effectively mitigates the impact of light source flicker on measurement results.<\/p>\n

Field of view correction<\/strong>
\nIndoor UGR (Unified Glare Rating) and DGI (Daylight Glare Index) measurements both use a fisheye lens with a 180\u00b0 field of view. However, the human eye\u2019s observation field of view is 143\u00b0 horizontally and 124\u00b0 vertically. Therefore, glare analysis needs to be adjusted according to the human eye\u2019s observation range. Konia Optoelectronics provides a field-of-view correction function tailored for human eye observation.<\/p>\n

Customize light source analysis area<\/strong>
\nWhen optimizing the design of lighting scenarios, it is essential to understand the contribution of each luminaire or light source at specific locations to glare. This information is used to adjust and optimize the installation position and angle of the luminaires. Konia Optoelectronics offers a manual selection feature that allows users to delineate specific light source areas and provides the glare contribution of the selected region independently.<\/p>\n
