Method and device for light commissioning

A method for creating a navigation path for navigation in an indoor space based on measured lighting from a lighting system arranged in the indoor space, wherein the lighting system comprises a plurality of light sources, wherein the method comprises the steps of:

• defining a position, P0, in the indoor space,
• defining a subspace, S0, of the indoor space comprising the position, P0, wherein the subspace, S0, comprises at least one light source of the plurality of light sources,
• setting the intensity level, I0, of the at least one light source in the subspace, S0, to an intensity level value,
• measuring a light intensity, IL0, in the position, P0,
• and in an iterative manner from i=1, 2, . . . , to n,
• defining a position, Pi, in the indoor space,
• defining a subspace, Si, of the indoor space comprising the position, Pi, wherein the subspace, Si, comprises at least another light source of the plurality of light sources,
• setting the intensity level, Ii, of the at least one light source in the subspace, Si, to an intensity level value,
• measuring a light intensity, ILi, in the position, Pi, and
• registering and storing a spatial relation between
• the measured light intensity, ILi, in the position, Pi, and
• the measured light intensity, ILi-1, in the position, Pi-1,
• to a path register,
• and
• creating a navigation path in the indoor space based on the path register.
