description A method for an image-based measurement of a scene using a handheld apparatus, including a recording of at least one first image and one second image of the scene by at least one camera of the apparatus, a photogrammetric evaluating of the first and the second image, and a graphic outputting of an image representation of the scene on a display unit, characterized by an automatically proceeding edge measurement functionality, as part of which, in each case without user intervention, edges in the scene are identified utilizing at least one image of the scene, edge lengths of the identified edges are ascertained based on the photogrammetrically evaluated images, and the ascertained edge lengths are displayed in the image representation of the scene.
