Patent attributes
According to one or more embodiments, a system of generating a two-dimensional (2D) map of an environment includes a 2D scanner and a wall sensor positioned at a fixed position with respect to the 2D scanner, the wall sensor detects a presence of an internal element inside a wall in the environment. Further, the system includes one or more processors operably coupled to the 2D scanner and the wall sensor. The processors generate a wall map of a wall in the environment, the wall map including an occupancy grid with a plurality of cells, a cell representative of a corresponding portion of the wall, and the cell indicative of the occupancy of an internal element in the corresponding portion. Further, the processors associate the wall map with a location of the wall in the 2D map of the environment.
