Title:
METHOD FOR ASSESSING THE PHYSICALLY BASED SIMULATION QUALITY OF A GLAZED OBJECT
Document Type and Number:
WIPO Patent Application WO/2022/135942
Kind Code:
A1
Abstract:
A method for assessing the physically based simulation quality of a glazed objects, in particular glazing buildings or glazing vehicles. A hyperspectral canopy hemispherical image of a real sky at given daylight conditions and an image of glazed object, both synchronously acquired, are processed into a physically based rendering to evaluate the colour difference between glazing parts of a rendered representative glazed object and the glazed object of the provided image. An outstanding advantage is a realistic rendering of a glazed object by an accurate rendering of reflecting effects coming from the sky onto glazed parts whatever the viewing angles.
