with mission waypoints. Selecting ‘On’ overrides waypoint actions and en-
ables continuous shooting. Conversely, selecting ‘Off’ will override way-
point actions and disable continuous shooting.
Default value: Auto
The ‘Camera parameters for mapping’ section is used to define detailed parame-
ters related to the camera and has the following functions:
•
Pitch angle: By default the swinglet CAM takes images at a default esti-
mated pitch angle of 10
◦
relative to the horizon. This angle provides the
best compromise between image quality and flight endurance. In some
cases, however, you may wish to change this value to suit your imaging
needs.
Increasing this angle to 15
◦
provides a slightly more perspective view of
a building. Note, however, that a higher pitch angle will cause the drone
to slow down every time it takes an image, losing altitude and decreasing
flight time and longitudinal overlap.
Decrease the pitch angle down to 0
◦
can capture more vertical images of
the ground if mapping precision at low altitudes is of utmost importance.
However, decreasing this angle will cause the drone to lose altitude with
each image taken, requiring it to return to the target altitude before taking
another image, once again decreasing both flight time and longitudinal
overlap between images.
Default value: 10
◦
•
Distance between photos: Check the ‘Use manual parameters’ box to
manually set the distance between photos in the direction of flight. This
option may be used to override the automatic settings based on altitude
and longitudinal overlap.
Default value: Unchecked, Distance between photos: Automatic
Note: Depending on the altitude and the wind the desired distance
between images may not always be achievable. The minimum dis-
tance with no wind and at sea level is around 35-40 m.
