METHOD FOR DETECTING AND PRESENTING A SURFACE CHANGE ON AN OBJECT, DEVICE FOR PERFORMING THE SAME, AND SYSTEM COMPRISING A

The invention relates to a method for detecting and presenting a surface change (20) on an object (22), in particular a building, preferably a floor of a building, in which, in at least one method step (70), a surface (24) of the object (22) is detected by means of a plurality of images by means of a camera (26) of a device (12), in particular a robot, which camera is movable relative to the object (22), wherein in at least one method step (80), by means of an evaluation unit (34), at least one surface change (20) in a surface portion (50) of the surface (24) is determined by comparing at least two images of the surface portion (50) detected at a distance from one another over time, and wherein in at least one further method step (82), by means of the evaluation unit (34), at least one surface change (20) in the surface portion (50) is determined by means of the evaluation unit (34). The position of the at least one surface change (20) on the object (22) is determined by means of the distribution of the surfa
