13. Method for recording ambient scans in a forest stand with a device according to claim 1 having a base on which, in a first step, the first laser scanner is arranged in the first viewing point on the base and the first laser scanner performs a first ambient scan from the first viewing point, characterized in that, in a second step, a second ambient scan is performed from the second viewing point.

14. The method according to claim 13, characterized in that the first laser scanner is displaced between the first ambient scan and the second ambient scan from the first viewing point to the second viewing point.

15. The method according to claim 13, characterized in that the first laser scanner is pivoted between the first ambient scan and the second ambient scan from the first viewing point to the second viewing point.

16. The method according to claim 13, characterized in that the first laser scanner and the at least one second laser scanner, which are arranged in the second viewing point, perform the first ambient scan and the second ambient scan.

17. The method according to claim 14, characterized in that the first laser scanner performs ambient scans during the displacement.

18. The method according to claim 13, in that the laser scanner is rotated around its own vertical axis (H) in one of the viewing points to perform the ambient scan.

19. The method according to claim 13, characterized in that a recording module with a satellite-based radio module provides recorded data with a temporal and local assignment by blockchain technology.

20. The device of claim 1, wherein the second viewing point is spaced from the first viewing point by a length (L), wherein the length (L) is between 1 meter and 2.5 meters.

Description

[0044] FIG. 1 shows a first embodiment of a device according to the invention in a side view;

[0045] FIG. 2 the first embodiment in a section according to line II-II in FIG. 1;

[0046] FIG. 3 a second embodiment of a device according to the invention in a side view; and

[0047] FIG. 4 a third embodiment of a device according to the invention.

[0048] FIG. 1 shows a device 1 in a first embodiment. The device 1 has a base rod 2, which is mounted on a stand 3 so that it can be rotated about a rotation axis A. The base rod 2 has a drive 4 to the stand 3. On the base rod 2 a first laser scanner 7 and a second laser scanner 8 are arranged in a first viewing point 5 and in a second viewing point 6 respectively. These two laser scanners 7 and 8 can each be rotated around their vertical axis H. In the embodiment shown, a drive is provided to rotate the laser scanners 7 and 8 relative to the base rod 2. The two viewing points 5 and 6 have a length L between them, which is about 1.5 m.

[0049] The device 1 shown in FIG. 1 is located on a slope H with an approximate inclination by an angle . The stand 3 in this embodiment is an earth spike, which is driven into the earth either vertically (shown in dashed lines), or normally to the slope H. If the stand 3 is vertically aligned, the base rod 2 can be swivelled in relation to the stand and can be fixed, for example, with a screw essentially parallel to the slope H. This makes it easier to capture the surroundings, since otherwise, on a steep slope, part of the image would only show the slope H.

[0050] FIG. 2 shows a laser scanner with an aperture angle , which is 120 in the embodiment shown.

[0051] FIG. 3 shows a second embodiment of the device 1, where only the first laser scanner 7 is provided, which is located in the first viewing point 5 at the considered moment. The first laser scanner 7 can be moved along the base rod 2 either manually or via a drive until the second viewing point 6. The stand 3 is designed as a tripod in this embodiment.

[0052] A third embodiment of device 1 is shown in FIG. 4. In contrast to the other embodiments, the base rod 2 is arranged eccentrically with a length L/2 around the rotation axis A and, as in the second embodiment, only a first laser scanner 7 is arranged first in a viewing point 5. The base rod 2 is pivoted in a second step, so that the first laser scanner 7 is then arranged in the second viewing point 6.
