  • Patent number: 10491297
    Abstract: Multiple luminaires are mounted contiguously in a plane, along a straight line or following a one or two dimensional contour, but with a visible periphery between each adjacent pair. A different signal is embedded into the visible illumination emitted by each luminaire, which an image processing module can detect from one or more images captured by a camera. An angle-dependent mask is arranged to cover at least the periphery between adjacent luminaires, such that an appearance of the periphery when viewed from the environment through the mask varies as a function of viewing angle, becoming less visible at greater values of viewing angle (being the angle between a corresponding viewing direction and a normal to the plane, line or contour). The image processing module distinguishes between the different signals based on the periphery being visible when captured from less than a predetermined value of the viewing angle.
