METHOD FOR DETERMINING CONTRIBUTION AND ORIENTATION OF LIGHT SOURCES AT A PREDETERMINED MEASUREMENT POINT

A method (300) for determining contribution of light sources (103) at a first predetermined measurement point (121), the method comprising the steps of: positioning (310) a light sensor (129) of a sensor unit (117) comprising a matrix of light sub-sensors (130) at the first measurement point, and or...

Summary:A method (300) for determining contribution of light sources (103) at a first predetermined measurement point (121), the method comprising the steps of: positioning (310) a light sensor (129) of a sensor unit (117) comprising a matrix of light sub-sensors (130) at the first measurement point, and orienting the light sensor toward the light sources; setting (320) an exposure level or a gain level of the sensor unit at a level sufficient to form a digital image wherein each of the majority of light sources within a field of view of the light sensor are distinguishable; taking (320) a digital image (420) by the sensor unit of the light sources; identifying (330) each pixel or pixel group (P) of the digital image that represent each light source of the majority of light sources; and determining (340) pixel values of each pixel or group pixel group of the digital image that represent each light source.
