Title: A METHOD FOR DETERMINING A SPATIAL LIGHT DISTRIBUTION IN AN ENVIRONMENT
Abstract:
The present invention relates to a method determining a spatial light distribution in an environment. The method comprising: acquiring (602) a spatially resolved light data set (100) by collecting light from the environment (202) using a camera, wherein the light data set (100) comprises a plurality of data elements of a first type (106), each data element of the first type (106) being associated with a vertical angle span and a horizontal angle span, wherein the vertical angle span and the horizontal angle span pertain to angles from which light from the environment (202) is incident on the camera, and each data element of the first type (106) comprising data pertaining to an amount of incident light within a first spectral range; and determining (604), based on the light data set (100), a vertical spatial distribution (122) of the light within the first spectral range. The measuremnet is taken with a RGB camera and the pixel intensities of row are summed up and averaged.
