Abstract: A process and arrangement automatically generate a floor plan of a building. A set of voxels in the form of polyhedrons is computationally generated and together fill the floor space. The edges of the polyhedron are parallel to the axes of a specified three-dimensional coordinate system. A camera (IR) is moved through the story and generates a sequence of images. The respective position and orientation of the camera (IR) while generating an image are measured. Characteristic key points (S1?, S2?, . . . ) are determined and positioned in the coordinate system. Free voxels (Vx, Vy), i.e. voxels inside a room, are determined. At least one cluster, including a topologically connected set of free voxels, is generated. An enveloping body is placed around each determined cluster. Each enveloping body describes the respective boundaries (W, F) of a room (R.x) of the story.
