Abstract: Method for creating a spatial model of a target object with a hand-held distance measuring device, the device comprising a laser distance meter, a camera, a computing unit and a data storage device, the method comprising measuring with the laser distance meter one or more distances to the target object from different positions, storing the measured distances in the data storage device, capturing with the camera a plurality of images of the target object, wherein each of the measured distances is associated with one of the captured images, determining with the computing unit relative camera poses for the plurality of images, and calculating with the computing unit based on the plurality of images and on the determined relative camera poses a three-dimensional geometry of the target object.
