Abstract
A robotic cleaning device and a method for operating the robotic cleaning device to detect a structure of a surface over which the robotic cleaning device moves. The method includes illuminating the surface with structured vertical light, capturing an image of the surface, detecting at least one luminous section in the captured image, and determining, from an appearance of the at least one luminous section, the structure of the surface.
