Abstract

A method for simulating, at an instant, the illumination of an indoor scene observed by a camera and being illuminated by outdoor light, the method comprising: a first preliminary phase (P1) including: obtaining (S003, S004) a reflectance map of the scene elaborating normalized radiosity maps for the contribution of the sky and the ground, a second phase (P2) carried out within a first given duration from the instant including: obtaining (S007) the position of the sun, obtaining (S008) a normalized radiosity map for the contribution of the sun, a third phase (P3), including: acquiring an image of the scene, determining (S014, S015) brightness scale parameters for the ground, the sky, and the sun. The invention also proposes tracking the camera position.
