Abstract

The disclosure is based on a hand-held laser distance measuring device comprising at least one laser unit which is configured to determine a first distance using a laser beam emitted in a first relative direction. The laser unit is further configured to determine at least one second distance, near instantaneously, using a laser beam emitted in at least one second relative direction which differs from the first relative direction.

Claims

1. A handheld laser distance measuring device comprising:

at least one laser unit including a laser beam guidance apparatus configured to guide a laser beam in different directions, the at least one laser unit being configured (i) to determine a first distance in a first relative direction using the laser beam, and (ii) to determine, almost simultaneously, at least one second distance in at least one second relative direction that differs relative to the device from the first relative direction, using the laser beam; and

an input unit configured to set an angle, at least between the first relative direction and the at least one second relative direction.

2. The laser distance measuring device as claimed in claim 1, further comprising a computer unit configured to set an angle at least between the first relative direction and the at least one second relative direction.

3. The laser distance measuring device as claimed in claim 2, wherein the computer unit is further configured to regulate the laser beam guidance apparatus in an operating mode by virtue of a first measurement point of the first relative direction and a second measurement point of the at least one second relative direction being arranged at a predetermined distance from one another.

4. The laser distance measuring device as claimed in claim 1, further comprising a computer unit configured to determine at least one contour of a measurement object.

5. The laser distance measuring device as claimed in claim 1, further comprising a computer unit configured to determine at least one distance from a measurement point on a first surface to a measurement point on a second surface spaced from the first surface.

6. The laser distance measuring device as claimed in claim 1, further comprising a computer unit configured to determine an angle of intersection between at least two measured surfaces.

7. The laser distance measuring device as claimed in claim 1, wherein the at least one laser unit is further configured to generate at least one projection line.

8. The laser distance measuring device as claimed in claim 1, wherein the at least one laser unit is further configured to project a value of a length of a distance.

9. The laser distance measuring device as claimed in claim 1, further comprising a position capture unit configured to capture at least one alignment of at least the at least one laser unit in space.

10. The laser distance measuring device as claimed in claim 9, further comprising a computer unit configured to calculate a further distance at least from an alignment captured by the position capture unit and two distances measured in a same relative direction.

11. The laser distance measuring device as claimed in claim 1, wherein the at least one laser unit determines the first distance and the second distance within 500 ms.

12. The laser distance measuring device as claimed in claim 1, wherein the at least one laser unit determines the first distance and the at least one second distance within 50 ms.
