Abstract

The proposed method for operating a laser distance measuring device, in particular a hand-held laser distance measuring device, is based on a method in which laser radiation is emitted to a target point by means of an emitter unit, laser radiation reflected back from the target point is detected by a receiver unit with a detection surface, at least one image of at least one target environment of the target point is captured by at least one camera, and a representation of the image, overlaid with a marking of the target point, is displayed on a screen of the laser distance measuring device. According to the disclosure, a parallax error in the representation of the image, overlaid with a marking of the target point, is corrected according to an estimated distance to the target point. The disclosure also relates to a corresponding laser distance measuring device.
