Abstract
The invention relates to a method for controlling a light source (7), the method using (a) at least one pose estimate (1) of a camera (8) configured to capture one or more images of a scene of interest (13) which comprises at least one landmark (9), as said light source is operated to emit light which illuminates said scene of interest, (b) a landmark map (2) comprising at least 3D location information of a plurality of landmarks comprising the at least one landmark in the scene of interest, (c) an illumination model (3) describing a relationship between an emission illumination power and reflection illumination power, wherein said emission illumination power is the power of light emitted by the light source (7) to illuminate said scene of interest, and said reflection illumination power is the illumination power of light reflected by one or more landmarks in said scene of interest and received by the camera, and (d) a predefined threshold reflection illumination power (4). The method comprises the following steps: (a) determining (5), for at least one of the plurality of landmarks, at least one optimized emission illumination power of light (6) to be emitted by the light source, a…
