Night-time Mobile Mapping of Road Surface Luminance

Lighting – which is measured in luminance – plays a key role in improving road safety. A new measurement system is now being developed to evaluate night-time road lighting conditions based on luminance-calibrated 3D point cloud data. This new approach integrates imaging photometry, which... (read more)
