Technical solutions are described for generating an augmented reality map of an environment. An example method includes obtaining, by a 2D scanner, a 2D scan set including 2D coordinates of points in the environment. The method further includes capturing and displaying, by a portable computing device, a live video stream of a field of view, the portable computing device being fixed at a relative position with respect to the 2D scanner. The method further includes displaying a selection marker overlaid on the live video stream at a location in response to a user input. The method further includes projecting a beam of visible light on an object point in the field of view, corresponding to the location on the display of the selection marker. The method further includes receiving, via the portable computing device, a selection input and in response generating and storing an annotation at the object point.
