○
It is best practice not to have other people closely accompany the operator during the
scan acquisition as they will be scanned throughout the map leaving streaks of data
and potentially corrupting the solution in feature poor environments.
○
If people are required to follow the operator they should ideally maintain a distance
of 20m or more from the operator.
Setting up 3D markers
If you have a field area that is poor in 3D features, you should consider putting up 3D markers in your
area. This can be done as follows:
1.
Consult Figure 2 for an example of how to set-
up your survey area. A’s are (drone) ma
rkers,
B’s are 3D markers. The BASE acts as a 3D marker and as a point of departure and return for
every loop. All markers should remain stationary throughout the survey! These markers are
needed for the scanning algorithm.
21.
Make sure that you have plenty o
f 3D markers in the area you’ll be scanning; all
measurements should contain at least one 3D marker in close proximity to the path taken.
In
figure 2 the 3D markers (B’s) were placed in the centre of each loop.
22.
Clearly mark the borders of the area you’ll b
e scanning (e.g. with drone markers). This will
make it easier to follow the path that you planned.
In figure 2 the borders were marked by
A’s in every corner and in between.
23.
Put a 3D marker in the centre of the area you’ll be scanning. This will act as yo
ur BASE that
you’ll constantly loop back to (every loop should start and end at the base).
24.
Place (3D) markers on strategic spots that can help you follow the route you planned.
In
figure 2 drone markers (A’s) were used to define the borders of the
survey area. Furthermore,
they serve as visual cues for the path to be followed. 3D markers (B’s) in the centre of the loop
also make it easier to follow a predefined path.
