Course Angle
The route angle can be adjusted, and the starting and ending
positions of the route will be adjusted accordingly. Note: the
estimated time of the task varies for different course angles. By
adjusting the course angle, the task with the shortest estimated time
can be planned to improve the operation efficiency.
Elevation
Optimization
When enabled, the aircraft will fly to the center of the mapping area
to collect a set of oblique images to optimize the elevation accuracy.
It is recommended to enable this option for orthophoto operation,
which requires high elevation accuracy.
This feature is not supported for Oblique Collection.
Upon Completion
The flight action performed by the aircraft after completing the
operation. The default selection is Return to Home.
Side Overlap Ratio/
Frontal Overlap Ratio
Side overlap ratio is the overlap ratio of two pictures taken on two
parallel paths. Frontal overlap ratio is the overlap ratio of two pictures
captured consecutively in the same heading along the flight path.
The overlap ratio is one of the key factors affecting the success of
later model reconstruction. The default side overlap ratio is 70%,
and the default frontal overlap ratio is 80%, which is suitable for
most scenarios. If the mapping area is flat and has no undulations,
the overlap ratio can be appropriately reduced to improve
operational efficiency. If the mapping area has large fluctuations,
it is recommended to increase the overlap ratio to ensure the
reconstruction effect.
When using Oblique Collection, two more settings will be
available: Side Overlap Ratio (Oblique) and Frontal Overlap Ratio
(Oblique). The overlap ratio of oblique photos can be lower than
that of orthophotos.
Margin
The distance of the flight area beyond the mapping area. The
purpose of setting the margin is to ensure the edge accuracy of the
mapping area by capturing images outside the mapping area.
Smart Oblique does not support setting margin; it will
automatically expand the margin according to the range of the
mapping area and the gimbal pitch.
Photo Mode The camera's photo mode. The default selection is Timed Interval Shot.
Custom Camera
Angle
Once enabled, users can customize the aircraft yaw angle and the
gimbal pitch angle. Only the Ortho Collection in the Area Route
supports customizing the camera angle.
Route Start Point
The starting point of the route can be customized in the optional points
of the map view.
Takeoff Speed
After the aircraft takes off and reaches the flight route altitude, the
flight speed before entering the flight route. This speed is not the
vertical take-off speed of the aircraft. It is recommended to set it to
the maximum to improve operational efficiency.
