1. An optoelectronic laser distance-measuring instrument, comprising a portable housing (2) with reference points (3a, 3b, 3c) arranged on an outer edge thereof;

  • a radiation source (4);

    a radiation receiver (5) for a laser beam (6) and associated with the radiation source (4);

    a microcontroller (9);

    a keypad (10) associated with the microcontroller;

    a read-off from a handling distance, display (11) for displaying a measuring result (14);

    and an aiming in laser beam direction, camera lens (7) with an imaging sensor (8), wherein a target area (12) detected by the camera lens (7) is graphically shown in the display (11), at least partially together with a virtual measuring spot (13) calculated by the microcontroller (9) and with the measuring result (14), wherein a position of the virtual measuring spot (13) calculated by the microcontroller (9) can be corrected relative to the target area (12) depicted in the graphic display (11) as a function of the measured result (14) in terms of a parallax error Δ
