Abstract: A mapping method is disclosed that includes (i) memorizing at least one reference image of an environment to be mapped containing a specific arrangement of a plurality of markers organized in cells; wherein each cell is identified by a marker or by a combination of markers; the plurality of markers comprising at least a number of different types of markers equal to a type-number; (ii) detecting, by a moving video camera, a video sequence wherein the environment to be mapped is, at least in part, framed; (iii) identifying in at least one frame of the video sequence one or more cells being part of the specific arrangement of markers of the reference image; and (iv) calculating, on the basis of the data regarding the identified cells, at least one homography for the perspective transformation of the coordinates acquired in the video sequence into coordinates in the reference image and vice versa.
