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 Smart Oblique and Oblique
tasks.
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 task, 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.
Oblique and Smart Oblique tasks also support the following specifications:
Specifications Description
Gimbal Pitch
(Oblique)
Adjusts the camera pitch angle when capturing oblique photos.
The default angle is -45°. When the altitude difference of the
buildings in the mapping area increases, it is recommended to
increase the angle to capture more images of the upper floors of
the buildings. When the buildings in the mapping area are dense, it
is recommended to appropriately reduce the angle to capture more
images between buildings.
When capturing images with Smart Oblique, the option is Gimbal
Angle, and the default angle is 45°.
