Abstract

It is presented a method for illuminating an environment for localisation of a user device comprising a light source and at least one camera. The method is performed in an illumination determiner. The method includes determining a need for adjusting illumination, determining a field of view of the at least one camera of the user device, and obtaining environment data for elements within the field of view from previously stored environment data. The method also includes selecting at least one key element of the elements, and adjusting illumination of at least a subset of the at least one key element by adapting a light source.
