Abstract
An optoelectronic laser distance-measuring instrument (1) with preselectable or sensitive reference points (3a, 3b, 3c) arranged on the outer edge of a portable housing (2) and having a radiation source (4), an associated radiation receiver (5) for a laser beam (6), a microcontroller (9), keypad (10), a display (11), which can be read off from the handling distance, for the depiction of a measured result (14), a camera lens (7) that is aimed in the direction of the laser beam (6) and has a image sensor (8), whose detected target area (12) can be graphically depicted on the display (11) at least partially together with a virtual measuring spot (13) calculated by the microcontroller (9) as well as with the measured result (14).
